Winners and Losers in UK Funding

This could possibly stir another round of unhappiness with the physics funding in the United Kingdom.

The body overseeing UK astronomy and physics says some of its programmes will be cut back to save £81m by 2011.

Areas that will lose money are those deemed to be a low priority in a recent programmatic review.

They include support for the Integral space telescope and the Veritas observatory, both of which are concerned with the investigation of gamma-ray light; and Bison, an observatory network pursuing solar-terrestrial physics.

No word in this news report if funding is going to be restored to the UK's involvement in Gemini and the International Linear Collider, both of which they pulled out of during this last budget debacle.

Communicating With Your PhD Supervisor

In Chapter X of my "So You Want To Be A Physicist" essay, I mentioned the process of selecting your research adviser/supervisor for your graduate work. This is possibly the most important person in your academic life and selecting someone compatible is an extremely important aspect of your education.

In last week's Science, there's a wonderful essay on the same issue that focuses on your interaction with your PhD supervisor. It deals with communicating with your supervisor no matter what style he/she adopts. This is very important especially if your supervisor is a well-known scientist that is in very high demand. So this is definitely a useful essay if you are about or just starting your graduate program.

High-Tc Superconductors Are Very Kinky - Update 2

A new update to my first essay on the kink feature in the ARPES spectra of high-Tc superconductors. This time, it could throw a major wrench into the analysis done previously on this high-energy kink feature that has been seen around 500 meV. The new paper[1] disputes the idea that this high energy kink is intrinsic to the band dispersion of the material. Rather, they argued that it is an artifact of the momentum distribution curve (MDC) method. Their analysis of the energy distribution cureve (EDC) does not show the same effect for that energy range.

It would be interesting to see if the previous authors who have done the analysis on this high energy kink would respond to this paper.

Science and Maths Exams are Harder Than Arts Subjects, Say Researchers

Oooh.. now this is bound to stir up a whole bunch of hornet's nests.

Researchers at Durham University in the UK think they have evidence that shows that science and math subjects are harder than arts subjects such as English, social studies, etc. They used the grading scale in the UK's A-Level examinations as their data.

They analysed the GCSE and A-level results of almost a million students who sat exams in the summer of 2006, comparing marks in traditional sciences and maths with those in arts and humanities.

There were "substantial differences in the average grades achieved by the same or comparable candidates", they found.

A-levels in physics, chemistry and biology were marked a grade lower than A-levels in drama, sociology and media studies and three-quarters of a grade harder than English, religious education and business studies, the researchers said.

Examiners were half a grade more generous when marking students of the same ability in psychology A-level, compared with biology A-level.

For many of us, this isn't really that surprising. There have been plenty of anecdotal studies on a general consensus that the science subjects are more "difficult" both in high school and in college. However, there hasn't been any kind of systematic studies on this. Furthermore, I don't know if it is a fair comparison between the two, and certainly it is comparing apples and oranges.

Still, with the UK system, it may reinforce the fact that teachers or even parents may encourage students to take the easier subjects in their A-level exams, which may explain why the number of students in the UK taking the more difficult subjects has been declining for the past several years.

Supplemental Spending Bill Signed

The President signed the $186 billion supplemental spending bill which includes $338 million for science agencies in the US. Quick! What percentage of the total supplemental bill is that?! The majority of the money in the bill goes to you-know-where.

This is only a stop-gap measures that will prevent further layoffs at Fermilab and SLAC. The inherent problem not only in the budget, but in the fundamental philosophy of those in Congress hasn't changed. So there really isn't that many reasons to be optimistic at all.

Michael Lubell, a physicist at the City College of New York and APS director of public affairs, also points out that three key issues that physicists raised last December with budget makers remain “largely unaddressed”. These are cuts in funding for particle physics, the lack of support for national facilities, and the damage to America’s credibility as an international partner because of the decision to cut funds for ITER.

“Unless these issues are addressed some time in the next six months, the country will pay a heavy penalty,” said Lubell, who plans to continue lobbying over the 2009 budget.

Scientific Fraud

Is there more of it than you think? This article seems to think so.

The data presented in the article were restricted to the US health and biological science, so it simply "extrapolated" into the rest of science. Now, even if this is true, that there are "... three incidences of fraud for every 100 researchers...", one needs to evaluate two important things as far as physics is concerned:

(1) were these part of important, high-profiled work and publications?

(2) did it get through to the stage where it was being used as a valid source?

The two instances mentioned in the article (the Schon and Ninov debacles) certainly fit #1, but this is out of how many high-profiled work? The thing we need to keep in mind here is that these high-profiled work, published in major journals, are usually highly scrutinized. So one certainly cannot get away with a lot of things, much less, fraudulent results, since someone is bound to try and reproduce your results. This is why it is still a major puzzlement why Schon did what he did, as if he didn't think someone was going to try and reproduce his results. So these important works in physics usually are not affected by frauds, because it is just way too difficult to get away with it.

Now, certainly such things are less scrutinized in lesser journals. But most of these very seldom become significant work that we rely on. And this brings us to #2. How many of these frauds actually made it "out" and into the stages where they were applied and used? I don't know of any. Why? Because if it is fraudulent, it would not work, no matter how much you try! That was the problem with the Schon results, no one could reproduce it! It could not get out of the scrutiny part and into the applied/application part.

The point here is that fraudulent work in physics hasn't made it out too far for it to mislead or fool enough people. (I'm distinguishing this from outright crackpottery such as the "hydrino".) If it doesn't work, it doesn't work, no matter how one tries to hide the fraud. Science, and certainly physics, is still a slave to Mother Nature.

Because the PRACTICE of science is a human endeavor, it is why we have peer-reviewed process, and then further scrutiny by others in the field. If not, why bother with all of the circus? The public and the media should be made aware of this, and this is why any results or discoveries should be given the proper "gestation period" for the system to work. The fact that something has been published isn't really the end of the story, but rather the beginning of a detailed, careful scrutiny. It is when the public and the media forget about this is when they are "misled".

Physics Teacher Shortage in the UK

More physics secondary education problem in the UK. A new report indicates that one in for secondary schools in the UK no longer have a physics specialist teacher.

The survey shows substantial differences in the availability of physics teachers - both regional differences and by the type of school. And it raises concerns about the viability of physics as a separate subject.

In inner London, there is a tendency to have general science teachers rather than specialist physics teachers - and 50% of secondary schools do not have any physics teachers.

In contrast, in the Yorkshire and Humberside region, only about 10% of schools do not have any specialist physics teachers.

If we couple with with an earlier report and something that I truly believe that the problem with physics education is the way it is being taught in high schools, then the situation in the UK not very good. It is not just a matter of conveying the material. It is also the enthusiasm, creativity, and interest in the material. Presumably, someone who specialized in physics would tend to have those elements and would show it in his/her teaching.

Recapturing The Excitement Of Science

This article is all over the place and going in all directions. Its main emphasis is on the refurbishing of the Faraday Lecture Theatre at the Royal Institution in London. Still, it is an interesting read, especially on the historical aspect. Even more interesting, however, is that the impression that I have regarding the teaching of physics, and how the importance of physics is communicated to the general public, are articulated exactly in the article.

What a contrast with today. Last week, Ofsted reported that at both primary and secondary school level, science lessons were dull and there were not enough practical experiments. Teachers no longer entertain classes with explosions of powdered magnesium; gone are the bunsen burners for heating noxious mixtures in fragile test-tubes.

"Science is a fascinating and exciting subject," said Chief inspector Christine Gilbert. "Yet for many pupils, it lacks appeal because of the way that it is taught."

So why are so many people today happy to admit that they find science difficult and dull? Some of the blame may be laid at the doors of our education system, as the Ofsted report suggested. But there must be more to the flight from science.

People who would never admit to a lack of understanding of art or literature are happy to confess to total incomprehension where science is concerned. Yet our lives today depend as never before upon the outcomes of innovative science and technology. Without medical science, our lives would be shorter and more painful; without physics and chemistry, domestic conveniences that ease our everyday lives could never have been developed.

If, however, the reason for the general public's disenchantment with science is to be laid at the door of scientists unable or unprepared to communicate their subject so as to engage the interest and enthusiasm of non-specialists, then the Royal Institution is continuing a long tradition actively to counter such a trend.

This person in that speeding case may be exactly the product of such an environment, resulting in a complete disconnect between the advances in physics and the way we live our lives today.

SCOAP3 Expands

The push for having open-access peer-reviewed journal articles in high-energy physics now includes 3 more US National labs: SLAC, J-Lab, and Lawrence Berkeley.

Eventually, everyone will have access to those high-energy physics papers. So no one can claim any ignorance because he/she has been unable to access these peer-reviewed articles. :)

The Laws Of Physics Do Not Apply Here?

I was casually reading this article, which started out to be rather amusing. But then, it got VERY annoying especially when the ignorant judge started to give out his opinion.

A couple in England was contesting a speeding ticket when the wife was caught using a speed camera. Her husband, who happened to be a physicist, challenged the speeding ticket because the speed camera wasn't used according to instruction.

Now I have no idea who's right or who's wrong here, and this isn't really the focus of this blog post. However, what caused my jaw to drop was what the judge then said.

West Yorkshire Casualty Reduction Partnership spokesman, Philip Gwynne, said Mr Fielden appeared to be "defending his wife's honour" by "using the laws of physics."

He said: "However, the judge has ruled that in speeding cases it is the law of the land that matters – not the law of physics.

"Maybe it's time that we left physics in the classroom and allowed cameras to get on with their job which is to reduce injury and death on our roads and encourage people to drive within the speed limits," he continued.

Er... hello? Didn't the camera actually used physics to measure a vehicle's speed in the first place? And what's with confining physics to only "in the classroom" nonsense? Is he out of his mind making such a silly statement like that?

I hate to say this, but I shouldn't be shocked by such stupidity anymore. However, it also a reflection on those in physics to evaluate on whether we have done enough to emphasize the relevance of physics in our world today. Too often, big news on physics have come from very esoteric areas of physics. This includes high energy physics (the LHC is in the new a lot lately), astrophysics, etc., all of which are definitely important, but have a major disconnect between the subject area and what the general public are familiar with. They don't see how such things are applicable in their daily lives, and so have the impression that physics only deals with things that they don't use. They forget that their basic electronics, and most of their modern conveniences, came out of discoveries in physics, especially solid state/condensed matter physics.

Confining physics to the classroom is the last thing we want to do.

Zz.

EDIT/UPDATE: There's a bit of confusion on my part on who said that idiotic passage that I quoted from the news article. From this report, it appears that it is the person by the name of

Philip Gwynne, a spokesman for West Yorkshire Casualty Reduction Partnership, which runs the camera, said: "Maybe it's time we left the physics in the classroom. The cameras are there to encourage people to drive safely."

If this is true, than I apologize to the presiding judge, and this Philip Gwynne character has a serious problem. The "West Yorkshire Casualty Reduction Partnership" can't possibly want someone this ignorant to be their spokesman..... can they?

Public Outreach Program For Gravitational Wave Astronomy?

It could happen! It certainly isn't a very well-known area of physics/astronomy, so any kind of publicity and public outreach can certainly help in making the field more familiar to students and the public.

This preprint highlights the effort in introducing gravitational wave research by the LIGO collaboration to students, educators, and the public.

Abstract: The nascent field of gravitational-wave astronomy offers many opportunities for effective and inspirational astronomy outreach. Gravitational waves, the "ripples in space-time" predicted by Einstein's theory of General Relativity, are produced by some of the most energetic and dramatic phenomena in the cosmos, including black holes, neutron stars and supernovae. The detection of gravitational waves will help to address a number of fundamental questions in physics, from the evolution of stars and galaxies to the origin of dark energy and the nature of space-time itself. Moreover, the cutting-edge technology developed to search for gravitational waves is pushing back the frontiers of many fields, from lasers and materials science to high performance computing, and thus provides a powerful showcase for the attractions and challenges of a career in science and engineering. For several years a worldwide network of ground-based laser interferometric gravitational-wave detectors has been fully operational, including the two LIGO detectors in the United States. These detectors are already among the most sensitive scientific instruments on the planet and in the next few years their sensitivity will achieve further significant improvement. Those developments promise to open an exciting new window on the Universe, heralding the arrival of gravitational-wave astronomy as a revolutionary, new observational field. In this paper we describe the extensive program of public outreach activities already undertaken by the LIGO Scientific Collaboration, and a number of special events which we are planning for IYA2009.

Rising Cost of Oil 'Due to Speculation'

Finally, a research work done in the field of econophysics that I've actually found to be "relevant" and interesting! :)

This is a preprint by a group from ETH Zurich and the East China University of Science and Technology. In it, they claim that the rising cost in oil cannot be explained simply via supply and demand, that the major cost for the increase is due to oil speculation. You can read a review of this preprint at the Physics World website (free registration is required).

In an economy without speculation, the price of commodities tends to grow by a fixed percentage every year; this is an exponential rate of growth. But when an economy is influenced by speculation, the percentage increase can grow too. This gives rise to a power-law growth or, as the researchers call it, a “super-exponential growth”.

Sornette’s group has looked at three different models to see if oil prices exhibit super-exponential growth. Each of these models is based on a “log-periodic power law”, which characterizes the super-exponential growth, and contains three main parameters: the time when the bubble is expected to end; the exponent of the power law; and a scale factor. The researchers found that all three models fitted the oil-price data well, implying that the growth has indeed been a bubble.

Apparently, this group also predicted back in 2005 of the burst of the US housing market. And look at where we are now?

A Celebration of Learning?

I don't think so.

OK, so this is another one of those where I know that I am being overly critical here, and possibly nit-picking the issue. But still, based on my experience, the important distinction here is lost on many people who are not familiar with science and science education.

This story is reporting a group of high school and college students reading out loud various books in an effort to highlight the love of learning.

Inside the gazebo at Goettel Park was not the place Monday for anyone with a headache: Sebastian Notaro's voice boomed chapters from "College Physics" while Kate Sheldon read a cookbook. Andrea Catania recited from a Harry Potter book, and Chelsea Meredith read from the Quran.

Five others were reading aloud - all at the same time.

They even explained the reason why they are doing this silly exercise.

The event, which didn't have a name, had two purposes, including the collection of donations for a food pantry.

"It's a great way to revitalize intellectual spirit among our youth and show we are interested in learning," Miller said.

The food pantry drive thing, I have no problem with, and certainly can be effective if advertised. But the "we are interested in learning" part has a lot of things wrong with it especially as far as learning physics and mathematics are concerned.

First of all, just because someone can read something, doesn't mean he/she understands the content. Give a high school student a copy of Jackson's Classical E&M text and I can easily see that student reading it. He may stumble over a few words, but he can read it. But did he understood what he just read? I bet you cash the weight of that book that he did not. So just because someone reads off "College Physics" is meaningless as far as "learning" is concerned. That is why you never see authors of a college physics text at bookstores or coffee lounges reading chapters off their books. That would be absurd.

Secondly, one does not study physics and mathematics simply by reading it similar to what one would do when reading a novel, or a cookbook. You don't just sit in a chair with nothing else, and read Griffith's Quantum Mechanics text. While you can get some superficial knowledge out of doing something like that, you do not get the clear grasp of the content without actually working it out while reading the book. One learns and understand the material via working out the examples and following along the mathematics with pen and paper. It is also why these texts have exercise problems to test one's understanding of the material. This is the only way to really get a grasp of the physics. There are no shortcuts.

So while I can appreciate this as being nothing more than "symbolic" or a publicity stunt, the way it is done to emphasize "learning" is all wrong for understanding "College Physics". They could have done better if they read and understood the book and showed a demonstration instead. It certainly would have been a lot more exciting for the audience and may even had prevented headaches!

NOVA scienceNOW Premieres Wednesday

Got this info in my e-mail, and thought a lot of people might be interested in seeing this.

On Wednesday, June 25 at 9 p.m., PBS will present the season premiere of NOVA scienceNOW, NOVA's magazine-style "sister show" hosted by astrophysicist Neil deGrasse Tyson, Director of the Hayden Planetarium at the American Museum of Natural History. We think readers of Physics and Physicists will be interested in the show and hope you'll consider posting about it!

Wednesday's episode kicks off with a trip to the Soudan Underground Laboratory, a mine-turned-science lab where scientists are searching for evidence of dark matter. Later this summer, NOVA scienceNOW will travel to the Goddard Space Flight Center, where astronauts are preparing for a tricky last-chance repair mission to the Hubble Space Telescope; then, on July 23, we'll explore a radical step forward in the search for extraterrestrial intelligence; and on July 30, we will get the latest results from the Phoenix Mars mission. Every episode closes with Neil deGrasse Tyson's "Cosmic Perspective." For a taste of NOVA scienceNOW's unique take on physics, biology, math, and more, pay a visit to our YouTube page at http://www.youtube.com/novaonline

NOVA scienceNOW will run new episodes every Wednesday at 9 p.m. through the end of July, with rebroadcasts continuing in August. For a full list of upcoming segments, please see the attached press release. You can also find more on all these stories on the NOVA scienceNOW Web site: http://www.pbs.org/novasciencenow

And to check your local listings to confirm when NOVA scienceNOW will air near you, visit: http://www.pbs.org/wgbh/nova/schedule-local.html

I have talked to many people who are involved in MINOS. They are doing very fascinating work there, not the least of which, the location where they were in (or should I say, under).

Earth Will Survive After All

This came out last Friday, but I've only finished reading the whole thing just now. As reported in The NY Times today, all the concerned regarding the safety of our Earth due to the LHC has no significant probability of happening. This is based on the report that was released a few days ago.

And note the argument that I've used all along from the Auger Observatory results.

Do I think this will silenced all those doomsday-sayers? Nope, because most of them have already made up their minds with their so-called "facts". They'll still be singing the same tune even 10 years after LHC has gone into operation, because people never learn. A few of the people that I know will probably be at there when the LHC begins not only the first particle beam this July, but also the first collision, which from what I've been told, probably will begin in Sept. I told everyone to take some pictures, especially if a black hole starts appearing. I want to be the first to post a picture of a black hole swallowing up a part of Earth!

:)

EDIT: The preprint by Giddings and Mangano has now appeared on ArXiv.

http://arxiv.org/abs/0806.3381

The abstract is VERY clear:

Abstract: We analyze macroscopic effects of TeV-scale black holes, such as could possibly be produced at the LHC, in what is regarded as an extremely hypothetical scenario in which they are stable and, if trapped inside Earth, begin to accrete matter. We examine a wide variety of TeV-scale gravity scenarios, basing the resulting accretion models on first-principles, basic, and well-tested physical laws. These scenarios fall into two classes, depending on whether accretion could have any macroscopic effect on the Earth at times shorter than the Sun's natural lifetime. We argue that cases with such effect at shorter times than the solar lifetime are ruled out, since in these scenarios black holes produced by cosmic rays impinging on much denser white dwarfs and neutron stars would then catalyze their decay on timescales incompatible with their known lifetimes. We also comment on relevant lifetimes for astronomical objects that capture primordial black holes. In short, this study finds no basis for concerns that TeV-scale black holes from the LHC could pose a risk to Earth on time scales shorter than the Earth's natural lifetime. Indeed, conservative arguments based on detailed calculations and the best-available scientific knowledge, including solid astronomical data, conclude, from multiple perspectives, that there is no risk of any significance whatsoever from such black holes.

Any challenges MUST be done with physics, using at least the same level of meticulous study, and not by a series of quotations attributed via 2nd hand information from other people.

Rethinking Expertise

In an earlier post, I responded to a writer who called professional scientists the "most scientifically illiterate group in the US" and pointed out several fallacies of that statement. The problem here is that the level of expert knowledge that scientists consider themselves to have. We know what it means and how it feels to know something very well. This is why when we read other area of studies, we know we do not have the same level of expertise and would rather be inclined to refer to a true expert in such a field.

A book that was recently reviewed in Physics World seems to support what I had said. In Rethinking Expertise by Harry Collins and Robert Evans, the authors makes several distinction on the level of knowledge that a person can have.

The starting point of the book is the obvious realization that, in science or any other specialized field, some people know more than others. To develop this truism, the authors present a “periodic table of expertise” — a classification that will make it clear who we should listen to when there is a decision to be made that includes a technical component. At one end of the scale is what Collins and Evans (who is also a Cardiff sociologist) engagingly call “beer-mat expertise” — that level of knowledge that is needed to answer questions in pub quizzes. Slightly above this lies the knowledge that one might gain from reading serious journalism and popular books about a subject. Further up the scale is the expertise that only comes when one knows the original research papers in a field. Collins and Evans argue that to achieve the highest level of expertise — at which one can make original contributions to a field — one needs to go beyond the written word to the tacit knowledge that is contained in a research community. This is the technical know-how and received wisdom that seep into aspirant scientists during their graduate-student apprenticeship to give them what Collins and Evans call “contributory expertise”.

What Collins and Evans claim as original is their identification of a new type of expertise, which they call “interactional expertise”. People who have this kind of expertise share some of the tacit knowledge of the communities of practitioners while still not having the full set of skills that would allow them to make original contributions to the field. In other words, people with interactional expertise are fluent in the language of the specialism, but not with its practice.

I think most of us who work in science are fully aware of that, and that is why we seldom offer "expert" opinion on an area that we didn't specialize in. We KNOW what level of understanding is required to be able to make an original contribution to it. This is something crackpots are not aware of, and something that most of the public are not aware of when they talk about science and gave the impression that they have actually understood the issue on hand.

I think I have the "interactional expertise" in many areas, where I can actually engage in a semi-intelligent conversation with experts in those areas. However, if someone were to ask me for information about something in those areas, I would definitely refer to an expert, even though I believe that I know more about that area of study more than the average Joe off the street. Unfortunately, for some people, my referral to an expert somehow implied that I'm "scientifically illiterate". How logical is that?

A Resuscitated Science Funding

The US House of Representatives gave some lifelines to science funding in the US.

A third of a loaf is better than nothing. That's the feeling among the U.S. research community after the House of Representatives voted overwhelmingly yesterday to boost the current budgets of four key science agencies by $337 million. Although it was less than lobbyists had hoped, it's probably more likely to happen than the sizeable budget increases for next year approved this week by several House and Senate spending panels with jurisdiction over a number of science agencies. Lobbyists fear those numbers, for the 2009 budget year that begins in October, could represent high-water marks in a process that likely will extend far beyond the November elections.

This still has to be approved by the Senate, and then signed by the President, so it still has a long ways to go. Still, it has a good prospect of getting through. But this is only a temporary reprieve in the sense that it stops the layoffs, furloughs, etc. It still doesn't provide the money for any significant progress in funding. And then there is the continuing resolution of a crappy budget well into 2009.

All is still not well....

A Constant Constant

One of the issues that physics is trying to investigate is whether our physical constants are the same everywhere else in the universe. This just doesn't mean that it could be different in a different location of the universe due to the exotic conditions, but also at different times throughout the evolution of the universe. We have heard about the controversial idea that the fine structure constants could have varied at different times during the life of our universe.

Now comes the latest verification that comes from 6 billion light years away regarding the ratio of the mass of the proton to the mass of the electron. Murphy et al.[1] have reported that, within the limits of their experiment (which is the most accurate so far), they see no variation in this ratio. This means that this constant is the same even back that far in time.

You may read a review of this work here as well.

Physics Experiment With Your Microwave

This article describes a rather simple physics experiment that one can try with a microwave oven.

2 microwave-safe glasses

1 incandescent light bulb (60 watts works well)

1 microwave oven

Directions: Fill one glass with water. Put the light bulb in the other glass so it doesn't roll around. Put both glasses in the microwave. Turn the microwave on for three seconds (use the low-power setting if it has one).

Watch: If your microwave has a turntable, you will see the light bulb glow and dim as it travels. If your microwave doesn't have a turntable, repeat the experiment several times, moving the light bulb to different spots. Be careful, the light bulb gets hot! And don't run the microwave longer than five seconds at a time.

The science: Light bulbs glow when electrons speed across a thin metal wire called a filament, heating it to several thousand degrees. In this experiment, you harnessed the energy of the microwave radiation generated by your microwave oven.

It sounds interesting enough. But I can't help thinking "Holy Cow! Someone's not going to follow the instruction and will blow up his/her microwave oven!" Then again, a spark in a microwave oven is, in itself, a fun physics experiment. :)

The Problem With Using Scientists' Words To Support Religious Beliefs

This is a rather interesting article in Slate.com. It discusses the propensity of some people of quoting scientists, especially Einstein in particular, to support a particular religious point of view, or to say that even those great scientists believed in a deity.

I suppose when one deals with history or the nature of human interactions and beliefs, these quotes are the "data" one goes by to draw up a conclusion about that person. Of course, one only needs to examine a lot more than just a few quotes to get a more complete picture. Quotations need a frame of reference, a context, to give a fuller picture.

However, physics, on the other hand, are not done via a series of quotations, no matter how much one can cite such a thing. Most people not in this field of study seem to not be aware of that. If you look at the "debate" in the comments section on the issue of the LHC safety, you'll encounter a lot of "quotes" from various documents or from various people. This is done while the person extracting the quotes have no clue of the physics in question. One cannot engage in a physics discussion with people like that!

There is also another angle to all this. As a physicist, I highly respect the accomplishment of all the giants in this field. How can one not when one is benefiting from all the work and discoveries done by them. When I wrote my glowing comments about John Bardeen, while I admire his down-to-earth and unassuming demeanor, what I admire the most are his accomplishments, more than anything else. In other words, I look up to him as a physicist.

However, I also know that while I am in awe of these great scientists, I do not worship them. Their words are not the gospel, and they are or were still ordinary human beings. From what I have seen, many physicists also share the same level of acceptance. It is only those who somehow need need to put these people on such high pedestal that are examining each and every word that these prominent scientists say as if a favorable statement somehow justify their beliefs. "See? Einstein thinks the same way as I do!" Big Deal! Do you also understand General Relativity?

Can Special Athletes Really Defy Physics?

I shouldn't highlight this, but I'm pissed at the title. The title of this article has no relevance whatsoever with the content. So why even bother making such a mockery?

Sometimes, when you're talking about "willing" something to happen, you don't mean defying the laws of physics.

It's not like a great place-kicker can make a poorly struck field goal hook back against the wind.

Nor do I believe Tiger can physically cause a putt to change directions.

But great athletes can mix talent with desire -- plus an incredible confidence -- to create the result they need.

Nothing in the article comes even close to "defying physics", whatever that means. If Tiger Woods actually putted a golf ball downhill past a hole, and then the ball decide to act against gravity and comes back to go into the hole, now THAT is what I would call 'defying physics', thankyouverymuch! If that happened, it will be an even bigger news than his painful win at the US Open, I can tell you that!

Furthermore, these people seem to have forgotten that Tiger has LOST {gasp!} before. I'm guessing that he had tried to "will" many putts into the hole during those losses that didn't happen. Thus, some of the claims being made in that "news" piece seem to be based on only on sports highlights on TV that selects favorable "data", rather than examines the whole body of evidence.

I don't expect a thorough scientific analysis of the data for something like this, but at the same time, the inability for people to do some simple analytical evaluation is utterly shocking. This is why there are people who believe in various mumbo-jumbo such as The Secret.

Physics Agency Instigates Review

The Science and Technology Facilities Council (STFC) of the United Kingdom responsible for funding physics/astronomy programs has instigated a review of the way it conducts its business. This is after a universal criticism of the way it has caused the current funding debacle in the UK.

Too bad the US President and Congress are not brave enough to give themselves a review of what they did the the US physics programs.

Graduate Quantum Mechanics Reform

So I've written a bit on revamping the undergraduate physics laboratory. I believe that many, if not most, of the studies on better teaching and presentation methods have been directed at introductory college, undergraduates, and high school students. We don't hear much about graduate programs that need revamping. I suppose one assume that students at that advanced level can mostly learn on their own even with unequipped instructors and teaching methods that aren't well-developed.

So it is a breath of fresh air that I came across this preprint that actually talked about reforming how graduate level QM is taught.

Abstract: We address four main areas in which graduate quantum mechanics education in the U.S. can be improved: course content; textbook; teaching methods; and assessment tools. We report on a three year longitudinal study at the Colorado School of Mines using innovations in all four of these areas. In particular, we have modified the content of the course to reflect progress in the field in the last 50 years, use modern textbooks that include such content, incorporate a variety of teaching techniques based on physics education research, and used a variety of assessment tools to study the effectiveness of these reforms. We present a new assessment tool, the Graduate Quantum Mechanics Conceptual Survey, and further testing of a previously developed assessment tool, the Quantum Mechanics Conceptual Survey (QMCS). We find that graduate students respond well to research-based techniques that have previously been tested mainly in introductory courses, and that they learn a great deal of the new content introduced in each version of the course. We also find that students' ability to answer conceptual questions about graduate quantum mechanics is highly correlated with their ability to solve calculational problems on the same topics. On the other hand, we find that students' understanding of basic undergraduate quantum mechanics concepts at the modern physics level is not improved by instruction at the graduate level.

It's an interesting reading, and I've gone through it only quickly. I plan on reading it some more when I have the time. In the meantime, why don't you take a whack at it? :)

Physics of a Crane Collapse

With all the recent crane collapse going on, especially in New York City, this issue is certainly quite relevant. The following report is basically a transcript of a discussion with an assistant professor at the University of Maryland on the physics surrounding a crane collapse.

Can Real Life Physics Example Be Taken Too Far?

This news article reports on a physics question that does not sit well with a number of people.

In today’s Senior Physics exam, one of the problems is about a 'virtual' crime scene in which a victim is lying on the stage in the school auditorium with a gunshot wound to the head. There are four student suspects, and the problem has to do with calculating trajectory and other physics issues.

Many administrators are complaining.

Ruth Rosenfield President of the Montreal Teachers Association cannot believe how such an insensitive question could have been included in the exam, in light of the Dawson College shooting.

What do you think? Would a question like this be appropriate at Columbine high school, Virginia Tech, or Northern Illinois University? Or is there a better, less controversial way to test students about projectile motion without invoking such imagery?

Peter Higgs on the Dawn of the LHC

I mentioned earlier of an article referring to Peter Higgs and the impetus for him to come up the Higgs mechanism. One doesn't hear much about Higgs since he's a very low-key individual. So it is rather nice to read about him and what he's up to nowadays, especially on his recent visit to CERN. This news article is basically an update on him especially with regards to the LHC about to be powered up.

Fermilab Takes Stage in The Da Vinci Code-Like Physics Thriller

Physics thriller... hum.... when was the last time you see those 2 words together? :)

In any case, this article from Symmetry magazine is quite entertaining. It is a review and an interview with author Mark Alpert regarding his new novel "Final Theory". Most of the setting for this novel is set at Fermilab.

So hey, if Dan Brown can use CERN for "Angels and Demons", someone else certainly can use Fermilab for another thriller, no? :)

Physicists in Congress Calculate Their Influence

OK, let me first of all qualify myself by saying that I love, LOVE, reading this piece. I don't ever recall reading a report on this before, even though there have been previous articles on how physicists work in the US Congress. But this NY Times article on the 3 physicists in the US Congress is just plain delightful.

First of all, it highlights what I have argued earlier. What is important is not that one learned a specific issue, but that one is equipped to learn about things and think things through analytically, which is something that can be acquired as a skill in a science class.

There are 435 people in the House, Mr. Holt said, and “420 don’t know much about science and choose not to.” He recalled his exasperation when anthrax spores were discovered in the Capitol in 2001 and colleagues came to him and said, “You are a scientist, you must know about anthrax,” a subject ordinarily missing from the physics curriculum.

“The difference,” he said, “is we would be perfectly happy to pick up a copy of The New England Journal of Medicine and read about the etiology of anthrax.”

“In fact, we basically did that,” Mr. Ehlers said.

“We know more than our colleagues,” Mr. Holt said, “but not more than they could know.

But it is also sad to know that these lawmakers are saddled with the same level of ignorance that we have seen in the general public.

But sometimes, he said, the problem is just old-fashioned ignorance. Several times he has found himself “rushing to the floor” to head off colleagues ready to eliminate financing for endeavors whose importance they did not understand.

Once it was game theory. The person seeking the cut did not seem to realize that game theory had to do with interactions in economics, behavior and other social sciences, not sports, Mr. Ehlers recounted.

Then there was the time he rose to defend A.T.M. research against a colleague who thought it should be left to the banking industry. In this case the initials stood for asynchronous transfer mode, a protocol for fiber-optic data transfer.

One would think that if one is making such an important decision on something, that one would at least figure out what those things mean, especially when these lawmakers have staffers that can easily brief them on what they are.

It would be nice to have more people in power who have a more positive inclination towards science, and physics in particular. However, I'm skeptical that there will be significantly more.

High-Tc Superconductors Are Very Kinky - Update 1

Since I last completed the essay on the "kink" that is observed in ARPES spectrum of high-Tc superconductors, I've made 2 updates on the list of references. There have been 2 preprints appearing on arXiv that argued for the phonon origin of this kink. It there does not seem to be any end to this issue in sight, at least for now.

I wonder how the ARPES spectrum for the FeAs-based superconductors are going to look at. I bet many people are scurrying to be the first to report on that, assuming of course that one has a sizable single-crystal sample that can be easily cleaved in vacuum.

Physicist Debunks Cellphone Popcorn Viral Videos

It is really sad that we now have to address all kinds of crackpotteries that appear on YouTube. This is one such example.

YouTube videos that show a group of friends apparently cooking kernels of popcorn with their cellphones have been viewed more than a million times since they were uploaded last week.

The parlor trick (see embedded clip) looks amazing enough, but there's a hitch: It's not physically possible, according to University of Virginia physics professor Louis Bloomfield.

The problem here isn't these yoohoos who made the video. There will always be bored people like this who'd do one thing or another just to get attention. The problem is the people who view these things and would put some credibility into it. We then have to take some effort into debunking such crap. Even then, how many people who saw the video would actually see this response?

ITER Faces Cost Hikes And Delays

ITER hasn't been built yet, but already planners are warning of additional costs and a possible 3-year delay. (Link may be available without subscription only for a limited time).

Construction has not even begun on the ITER fusion reactor, which has been beset by political wrangling since its inception. Now its seven international backers are to be told they will have to come up with an extra €1.2 billion–1.6 billion (US$1.9 billion–2.5 billion) on top of its current €5-billion construction budget if the project is to be realized.

A report from a group of scientific advisers says the additional money is needed for critical design changes and for coordinating between the participant nations. And the experiment, already delayed, will not be completed until anywhere from one to three years after its current 2018 due date.

I guess some of the added costs are understandable. They had to incorporate earthquake safety for the building at Cadarache, which was not included in the original estimates because that was done before a site selection. Still, this is approaching (if not already overtaking) the ILC cost.

Making Sense of the Legendre Transform

I don't mind admitting that, while I was a graduate student, doing the Legendre transform in statistical mechanics was more of a "automatic" response rather than anything I actually understood. All I knew was that it got me from one place to the other, and that's that. Luckily, I don't quite use that piece of information, and that skill, in my everyday work. Unluckily, it means that, while I can still tackle such problems, I don't think I have that good of a grasp of it as I do with other aspects of physics.

That's why I was rather interested in reading this preprint on an effort to clearly introduce the Legendre transform. The authors used the standard, useful examples from classical mechanics and statistical mechanics, so physics majors should be well-familiar with the coverage. I've only looked through it rather quickly, with the intention of reading it more carefully later, but I think this could potentially be highly useful to many, especially if you are still in school learning this subject.

If you have read through this more carefully, and have some comments, please post them here. I'd like to hear them.

Science Education for Everyone: Why and What?

This is a rather provocative and often insightful essay posted on RedOrbit. It discusses not just why a general science education for non-scientists/engineers is important (we all know that), but also how it should be done. There are certainly many points in this essay that I agree, and I certainly consider the general introductory course in Physics, for example, not quite as effective to non-science majors in terms of getting across the point. That's why I have tried to put down some suggestion on how to do this better from the perspective of the introductory laboratory exercises.

However, the essay goes a bit further than that and tackles the larger issue, which by and large, I agree with. However, I also think that the author may be missing an important point in all of this. For example:

When we take as our goal the production of students who are comfortable handling science-related issues that arise in public debate, two propositions follow immediately, both of which are profoundly out of tune with the current academic consensus: (1) the students need to know something about all areas of science, rather than a lot about a single area; and (2) the students do not need to be able to "do" science.

I have absolutely no problem with that one. But this one is where the author missed something important:

A common response to the notion of teaching all of the sciences is the claim that the standard type of courses really teach something called the "scientific method," and that this will magically give students the background they need to read the newspaper on the day they graduate. This argument is so silly that I scarcely know where to start commenting on it. If it were applied to any other field, its vacuity would be obvious; after all, no one argues that someone who wants to learn Chinese should study French, acquire the "language method," and learn Chinese on his or her own. If we expect our students to understand the basic principles of ecology or geology, we should teach those principles explicitly. To do otherwise is to indulge in what I call the "teach them relativity and they'll work out molecular biology on the way home" school of thought. Incidentally, the notion that there is a magical "scientific method" explains a bizarre feature of the modern scientific community. I am referring to the fact that, outside of their fields of specialty, professional scientists, as a group, are probably the most scientifically illiterate group in the United States. The reason is simpie: scientists are never required to study science outside of their own fields. The last time a working physicist saw a biology textbook, for example, was probably in high school. If you do not believe me, ask one of your scientific colleagues how he or she deals with public issues outside of his or her field. Chances are you'll get an answer like "I call a friend," a technique I refer to as having recourse to the Golden Rolodex.

There are 2 problems with the author's view on this:

1. Scientists, more than anyone else, I would think, know the limitation of what they know, and because of that, realize that that what they know about other fields are only at the superficial level. I can bet you that if you take someone off the street and another physicist, for example, evaluate carefully what each of them know about stem-cell, I will put my money that the physicist has a deeper technical understanding of what a stem-cell is. Yet, if you ask them casually about such issue, you can easily get the "I call a friend" answer. Why? Because most of us do not consider our knowledge to be on the expert level on such issues. Our "threshold" for considering that we have a valid understanding of something is SO HIGH, because we know what is meant to be an "expert" at something, that many of the important aspect of understanding something are in the DETAILS which one are not aware of by knowing something just superficially! So to deduce the fact that a scientist would rather rely on someone who is an expert in the other field as being "illiterate" in that area of study is bogus! This is where an "anecdotal" observation simply doesn't have enough substance to draw up such conclusion.

2. When we teach students science, or physics in particular, we are teaching them SKILLS, or more specifically, analytic skills. It is a systematic examination of the problems, looking at correlations via the relationships between various quantities and parameters, and then looking at the cause and effect. If one look closely, what I've mentioned here is totally INDEPENDENT of physics! You can apply such skill to any problem that one encounters in life! In fact, I just applied such skill in #1 to argue why the author's conclusion is faulty! When I did my series on the revamping of the undergraduate physics lab, the whole purpose of it is to make a CONSCIOUS effort to get the students to examine these aspects of the formation of knowledge. How do we accept something as being valid? When someone claims that "... scientifically illiterate group...", how do we judge that to be valid rather than just simply accepting it blindly just because someone writes it on a webpage? This is the whole essence of our ability to analyze a situation to make a valid conclusion, and thus, forming knowledge about something. While you do not study classical mechanics in introductory physics classes so that you can be able to understand the issues surrounding global warming, the SKILL that you acquire in thinking through a problem in classical mechanics is very much relevant in your effort to decipher the wide range of information that is contained in global warming.

But why can't we simply cut to the chase and just teach the kids about global warming, stem-cells, energy crisis, etc.. etc? Because there are an infinite number of scientific issues that can pop up! We simply can't cover ALL of these issues or even anticipate what's to come in the future. Nanotechnology is something that is fast emerging as something that could create quite a social issue soon. And who knows, there are those that could easily pop up anytime soon. Teaching specific subject matter rather than the skills that are subject independent is like giving a hunger person some fish, rather than teach that person how to fish. You can satisfy the immediate needs, but next time the same type problem crops up, you have to continue to provide more, rather than just give that person the skill to be able to solve it on his/her own.

I'm not saying covering these areas in a general science course is useless. They are not. However, they should be covered as ILLUSTRATIONS of the application of the analytical skills they learned in science classes. When someone mention "stem cell", a scientist wanting to know about it will first ask "OK, what is a stem cell? How is it defined? What does it do, and what are the properties?" Then the scientist will ask "OK, what are the social/cultural/moral issues? What are the points from each side? Do they make any valid ideas that are consistent with what stem cell is defined as? Are their conclusions unique, or can there be more than one conclusions based on the same set of data and understanding?" These are ALL the same type of questions a scientist asks in his/her own line of work, and the same skill applies when he/she tries to understand the same thing. I don't see any other way to evaluate something to be valid. This will allow someone to clearly know the boundary between something that is based on solid, physical evidence, versus something that has gone beyond that into the realm of moral decisions and social opinions.

The problem right now, as I see it, is that there isn't a conscious effort to tell these students that this is one of the main purpose of them enrolling in such science courses. Many, if not most, of the instructors are simply teaching the content, with little emphasis, even if they are aware of it, of the analytical skills that are being "accidentally taught" through such classes. So these students are encountering a very valuable skill without knowing it, and they lose it afterwards because it isn't something that was visible to them as being important. It is why, I think, that we can start with the revamping of the intro physics labs, because this is where science is right in front of their face, and where they see how we accept or understand something. Only through a conscious and deliberate effort of emphasizing such analytical skills can we generate a general population that can do their own self-evaluation of the information that they are being bombarded with.

Advancing Research in Science and Engineering

A new report out of the American Academy of Arts and Sciences paints a discouraging picture for young researchers in light of funding situation here in the US. The white paper, titled "Advancing Research in Science and Engineering", boils down to two issues: "the need to foster early-career scientists and to encourage high-risk research", both of which are severely affected by the constant budget and funding problems.

The complete detail and the full report can be found here.

Where Mathematics And Astrophysics Meet

This is a terrific article that, as the article mentioned, illustrates Wigner's proposition of the "unreasonable effectives of mathematics in the natural sciences". It describes an example on where research work in a fundamental theorem of algebra actually has a practical solution for a problem in astrophysics.

In their article "From the Fundamental Theorem of Algebra to Astrophysics: A `Harmonious' Path", which appears in the Notices of the AMS, mathematicians Dmitry Khavinson (University of South Florida) and Genevra Neumann (University of Northern Iowa) describe the mathematical work that surprisingly led them to questions in astrophysics.

DOE Submits Yucca Mountain License Application

The Dept. of Energy submits a license application to the U.S. Nuclear Regulatory Commission for the federal nuclear waste repository at Yucca Mountain, Nevada.

I will clearly qualify myself as someone who support nuclear power, be it in the form of fission reactors that we currently have, or development/research of fusion reactors (though not necessarily in the current trend). However, the central issue is still the waste generated by nuclear power plants, especially those in the US that are prohibited by law to be reprocessed, unlike those done in Europe and Japan. So baring a change in policy, having a safe place to store these nuclear waste is of utmost importance if support for that energy source is needed. That's why, after a lengthy study, the DOE is now able to apply to make the Yucca Mountain a repository site.

We'll see how it goes...

Particle Physics Project Prioritization Panel

It was reported earlier that the particle physics in the US is getting some "lifeline", based on the initial report to be submitted to the Dept. of Energy. The panel, known as P5, has now submitted its final report to the DOE.

Various reports on this seems to indicate a reason for optimism, even when the panel gave a lukewarm support for the ILC. Unless there's some serious infusion of cash, I can't see how anyone can be optimistic about the situation, especially when another continuing resolution is almost a certainty for the 2008 Fiscal Year, where science in the US will be saddled with continuing the most devastating budget in recent memory.

A BCS-Like Gap for the New Iron-Arsenic Superconductor

This ought to throw a large wrench into any similarities between the copper-oxide superconductors and the newly-found iron-arsenic superconductors. A new measurement of the superconducting gap of the latter found that they behave very much like that predicted by the conventional, good-old BCS theory[1]. This means that, even though the crystal structure has similarities with the copper-oxide superconductor (and the notion that maybe the same theory might be applicable as well), the behavior so far rules out many of the exotic theories that have been set up for the copper-oxide superconductors. The authors argue that in light of this, new theories may be needed to describe the iron-arsenic superconductors.

Fasten your seatbelts, folks. It's going to be a long and bumpy ride here as more experimental data pour in.

The Milky Way Gets a Facelift

Or rather, our understanding of the Milky Way gets a facelift!

This was reported in today's Science's daily news update.

Forget what you thought the Milky Way looked like. The galaxy is far from the simple and elegant spiral-armed structure so often portrayed. New observations, presented today at the 212th meeting of the American Astronomical Society in St. Louis, Missouri, reveal, among other things, that the Milky Way is missing two of the four spiral arms it was thought to have. The findings should force a significant rethinking about how the Milky Way evolved and how its stars formed.

Horrors! We live in a "deformed" galaxy? :)

Dark, Perhaps Forever?

The New York Times has a lengthy piece on the current effort in the study of Dark Energy.

A decade ago, astronomers discovered that what is true for your car keys is not true for the galaxies. Having been impelled apart by the force of the Big Bang, the galaxies, in defiance of cosmic gravity, are picking up speed on a dash toward eternity. If they were keys, they would be shooting for the ceiling.

“That is how shocking this was,” Dr. Livio said.

But what I just don't quite understand is this kind of reaction:

It is still shocking. Although cosmologists have adopted a cute name, dark energy, for whatever is driving this apparently antigravitational behavior on the part of the universe, nobody claims to understand why it is happening, or its implications for the future of the universe and of the life within it, despite thousands of learned papers, scores of conferences and millions of dollars’ worth of telescope time. It has led some cosmologists to the verge of abandoning their fondest dream: a theory that can account for the universe and everything about it in a single breath.

Forget about the fact that I don't quite believe that such a thing is possible (i.e. "account for the universe and everything about it in a single breath") due to my view that the "TOE" is a fallacy. But why are they giving up so quickly? I mean, the discovery of dark energy has only been about 10 years old! This is a blink of an eye! Condensed matter physicists had dealt with the mysteries of high-Tc superconductors for 20 years already, and you don't hear them giving up! And they have more data and more discoveries to content with.

If the Dark Energy Survey really gets off the ground, there's a good chance that more evidence on the nature of dark energy will be revealed. Aren't people just salivating for that kind of information? I don't know what is there to be discouraged about. If I were in this field, I'd say that this might be some of the most exciting time to be alive!

Accelerators And Dinosaurs

This is an old article in Physics Today written by Michael Turner, but it is still a good piece to read if you are not familiar with particle accelerator physics and are still confusing particle accelerator with high energy physics. I've written about this topic (and the popular misconception) before, but here, Turner has written this better than I could.

I remind my readers that only a handful of the more than 15 000 accelerators in operation around the world are used in particle-physics research. This fact would not surprise Ernest O. Lawrence, who saw an importance far beyond physics research. He and his brother John, a physician, pioneered the medical applications of accelerators at Berkeley. Today, one-third of all accelerators are involved in medical applications, such as cancer therapy, imaging, and the production of short-lived isotopes. The other two-thirds are used for industrial applications ranging from micro-machining to food sterilization and for national security applications, which include x-ray inspection of cargo containers and nuclear stockpile stewardship.

This data clearly show why the field of accelerator physics transcends beyond just what they are normally perceived as, which is particle-physics/colliders. This is a good article to read if you're bored.

Boffo Box Office for Science Festival

All early reports seem to indicate that the first ever World Science Festival is a resounding success. They have either sold out or virtually sold out almost all of their events.

“Despite the fact that we are programmed against ourselves,” he says, “with almost seven or eight of our events happening at the same time in some instances, we have sold more than 90 percent of our seats and may in fact sell out the entire event.”

But what I found amusing was the dimwit who wrote the first comment to that news article. He/she seems to have the impression that the whole point of having a science festival is to encourage kids to have a career in science! If that's the case, we should bar adults from going to such events, since they definitely are too late to change careers! Yes, stop that 60-year old grandpa from attending Alan Alda's "QED"!

US Particle Physics Spared the Axe?

Well, maybe for now.

The High Energy Physics Advisory Panel (HEPAP) that advises the Dept. of Energy, met this past week to make recommendations on future directions of high energy physics funding and projects in the US. This New Scientist article seems to be painting a "rosier" picture than it really is.

You can read the preliminary report of the P5 meeting here.

There's nothing here that indicates that the politicians (and the President, now and the one to be installed in 2009) pays any attention to such report. After all, they've been known to ignore previous recommendations.

And as a follow-up to the post from yesterday regarding the anonymous donor that gave $5 to help Fermilab, Wired has this dead-on article about the sad state of American particle physics funding.

Say what you will about the relative importance of particle physics in everyday life, but how is it that a government spending $16.8 $2.9 trillion a year can't scrounge up enough change in the cushions to properly fund its premiere particle physics lab?

In the scheme of this country, we're not talking huge amounts of money here. The Federal government's total budget for the lab is $320 million. That's as much as we spend on, say, two-and-a-half F-22 Raptors, and we've managed to build over a hundred of those. Even just the interest on our nation's collective credit card was more than 1,000 times the Fermilab's budget.

... which is essentially what I had said earlier. People have somehow lost perspective for the scale of things.

Private Donor Gives Fermilab $5 Million

This is all over the Web already, but what the hey...

An anonymous donor gave $5 million to U. of Chicago to help with the financial debacle at Fermilab. This is reminiscent of the donation to RHIC a while ago to save it from being shut down temporarily due to similar budget constraints, although it wasn't from an anonymous donor.

The savings from the furlough allowed lab officials to keep the lab's particle smasher, the Tevatron Collider, running all out in its quest to spot the famed Higgs boson, the missing link in physicists' theory of the known fundamental bits of matter. Fermilab researchers hope to discover the Higgs before it's snagged by the more powerful Large Hadron Collider, which should turn on this summer at the European particle physics laboratory, CERN, near Geneva, Switzerland. The donation, which will be funneled through the University of Chicago, will enable the lab to stop the furlough after two of four planned rounds of leave. The lab was able to scrape up another $1 million, in part because about 50 employees have already jumped ship, Oddone says.

This is the second time in recent years that philanthropists have bailed out a beleaguered DOE lab. In 2006, Congress gave Brookhaven National Laboratory in Upton, New York, too little money to run its Relativistic Heavy Ion Collider, which is used to study a type of nuclear physics. James Simons, a theoretical physicist and billionaire hedge-fund guru then donated $13 million to Brookhaven to run the machine.

It paints a very sad picture of science funding in the US. $5 million is PUNY in the scale of funding sizes. Many corporations burn that much in just 1-day. And we haven't gotten into what minuscule percentage that is out of the military spending. Yet, it saved the lab from the debilitating furloughs that, from all anecdotal accounts, have crippled the Fermilab.

But still, this is only a temporary band-aid on a bigger disease.

Although the donation ends the furlough, it does not solve Fermilab's problems. "The grain of salt is that it really does nothing to change the uncertainty with regard to the future," says Brendan Casey, a Fermilab particle physicist. "So there's some relief, but the underlying tension is still there." A DOE advisory panel will meet tomorrow and Friday to discuss the future of the lab and particle physics in the United States.

Both the US public and the politicians need to decide if they wish to continue supporting particle physics in the US. Scientists would rather hear that they do not, rather than giving mixed, wishy-washy signal. At the very least, the former will allow many to simply pull up roots and move on, knowing that a political decision was made to abandon an important field of physics. Years from now, at least, we know who to blame for such a debacle and let history judge the foolish mistake these people made.

Wi-Fi Signals Causing Health Issues?

New reports are surfacing of certain people who are "electro-sensitive" and being affected by Wi-Fi signals, causing headaches and chest pains.

You'll understand if I read something like this with a large degree of skepticism. This is not new. I've reported this earlier with people who claim almost the same symptoms with cell-phone signals. Look at how credible those claims are.

I'm not saying these people didn't experience all this, and I'm not saying we shouldn't look into it. But considering the track record of such claims in the past (including claims about transmission power lines), we shouldn't enact bans and legislation just YET until there's clear evidence of a cause-and-effect. And let me tell ya, we are a LONG way off from that at this point.

João Magueijo’s Big Bang

I don't normally highlight either fringe science or something that is still so highly controversial that it requires more "gestation" period. But since this thing is going to be on TV tonight, I might as well point it out. The Science channel will be airing a documentary presenting the highly controversial view of cosmology from the point of view of cosmologist João Magueijo. He, if you have followed this field closely, is a proponent of the idea that the intrinsic speed of light has been varying over time since the beginning of our universe. I'm guessing that he is justifying this view based on the still-controversial observation that the fine structure constant may have varied over time (see here and here).

Still, this NY Times review of the documentary isn't that flattering.

Not everyone will be charmed, however, by the extent to which he and his producers apparently thought it was necessary to dumb down and dress up the science in question. Everything is presented in classroom metaphors, and not very vivid ones: shots of static on a television screen represent cosmic radiation; a stretchy sweater with a lot of extra buttons stands in for the expanding universe. An inordinate amount of screen time is also devoted to shots of the dreamy Dr. Magueijo staring at models of the solar system or lying on a deck chair and gazing at the sky.

It doesn’t help when he brings his own bad-boy biography into the picture (a habit that began with his 2003 book, “Faster Than the Speed of Light”). We’re treated to the story of how he had his Einstein-was-wrong-about-the-speed-of-light breakthrough while fighting a hangover, and to the sight of him chuckling while watching what appear to be fake home movies, with an actor playing the young João.

Unfortunately, I have other commitments tonight that I won't be able to watch this show, and I didn't set anything to record it. If you did catch it, can you post something here and let me know what you think of it?

The article did get one thing rather accurate, though. I've seen his pictures several times already before this (haven't met him in person yet), and I might even go out on a limb and say that he is one of the most good-looking physicist that I've ever seen. :) I'm guessing that the camera loves him, and in many circles, that's good enough for a TV show.

World Science Festival Debuts Tomorrow

If you are lucky enough to be in the New York city area, you can participate in the World Science Festival which will start tomorrow in Manhattan.

The festival website has more info and programs for this event.

Behind a Scientific Success, a Failed Texas Experiment

As the dawn of the LHC is upon us and the excitement growing by the day, a relic of what could have been the most powerful particle collider ever built sat decaying and gathering dusts in Texas. This article looks back at the debacle that was the Superconducting Supercollider what was supposed to be built just outside of Dallas.

The Tevatron ring measures about 4 miles in circumference. The SSC ring was to have been 54 miles in circumference, producing collisions 20 times more intense than the Tevatron.

The new European accelerator, called the Large Hadron Collider, will not be as powerful as the mighty SSC would have been. The Large Hadron Collider's ring, about 17 miles in circumference, should be capable of producing collisions about one-third as powerful.

The collapse of the SSC is also an example on how politics got into the way of a science project, especially in how Fermilab lost the opportunity to build it there. It also shows very clearly for the first time that physicists are not united behind such huge and horribly expensive machine. Phil Anderson, for example, testified on why he was opposed to such a facility.

The SSC would have made the LHC moot. However, the SSC collapse has also foreign partnerships with the US more weary about the US commitment to such endeavor. The recent budget cutbacks on the ILC and ITER only reinforced such point of view.

Brookhaven's Summer Sundays

I have mentioned this whenever they have their yearly open Summer Sundays. If you are anywhere near Long Island, NY, you really shouldn't miss the opportunity to visit Brookhaven National Laboratory during one of their Summer Sundays. You get to visit not only the lab in general, but also get to tour the facility that's open for visitors for that day. Typically, the days highlighting the NSLS and RHIC are two of the more popular and tend to have the largest number of visitors, and understandably so.

This is one of the few opportunities one gets to tour a world class science facility and gets to ask questions to scientists working there.

Speaking of Brookhaven, it seems that people are still publishing erroneous rumors and accusation towards the lab that are amazingly wrong (and presumably getting away with it). The lab wisely decided to address the inaccuracies published in a book titled "SWelcome to Shirley: A Memoir from an Atomic Town", and included references to the affect of the lab on that two and the surrounding area on Long Island. It is amazing that someone would publish a book and yet, hardly do any homework on what they are writing on. Unfortunately, many of the book's readers would probably never see these counter points against the book and so, these inaccuracies (lies?) will be perpetuated. This is usually the "source" of information for the "public" and these accusations are taken as gospel by many.

US National Compact Stellarator Experiment Cancelled

I suppose this is neither inevitable nor surprising. The National Compact Stellerator at Princeton Plasma Physics Laboratory has been shut down, mainly due to cost overruns and delays.

"In late 2006, it became clear that NCSX construction project would not be able to meet its approved baseline total project cost of $102M or its completion date of July 2009," said Under Secretary for Science Raymond Orbach in a statement. Since then the DOE, Princeton University, and Princeton Plasma Physics Laboratory (PPPL) have been reviewing their options for the project and PPPL. They concluded that "the budget increases, schedule delays and continuing uncertainties of the NCSX construction project necessitate its closure," said Orbach. The new proposed cost for NCSX was $170 million with an August 2013 start date, which would have put research at PPPL in peril said an April 2008 Office of Science report.

Outsider Science

Hey, if you're an amateur scientist/physicist and think you have some earth-shattering theory that you want to share, you may want to read this article from Symmetry before you hound other physicists with it.

I have been the recipient of several of these unsolicited e-mail and "manuscripts", and let me tell you that other than providing a good few minutes of laughter, I some time feel rather sorry for these people because, most often, the mistakes or inconsistencies were quite obvious. This despite the fact that many of these "theories" are often rather difficult to decipher because they are written in non-standard terminology. The words being used are familiar, but the context they are used in are rather odd. Certainly, the advice given in that article is very pertinent here:

To merit their attention, professionals say, an outsider would have to show that he’s done his homework. Serious contenders have to understand the language of physics and get their math right. Most importantly, any new theory must agree with past experiments.

A theory could predict that hula hoops will come bouncing out of CERN’s Large Hadron Collider in Switzerland, as long as it accounts for all the experimental data up to that point, Rizzo says. Too often, amateurs ignore that basic constraint.

I would say that the amateurs "ignore" that constraint because they tend to not be aware of all the experimental data, or are ignorant of the body of knowledge in that field of study. This is another example of what I categorize as "imagination without knowledge is ignorance waiting to happen". There's no substitute for doing one's homework, and claiming something that contradicts or inconsistent with existing data or observation without realizing such data exist reflects one's ignorance. No professional scientist wants to be shown to be in ignorance of the state of knowledge of the field he/she is in, but this is what many "amateur physicists" continue to exhibit without shame.

Quantum All The Way

This is from a few weeks ago, but the issue is so important and interesting, I should still mention it on here. This was also the article I was reading on the plane while I was on my most-recent vacation. It was fascinating enough that it didn't put me to sleep and entertained me for several minutes.

This article was written by Phillip Ball in May 1st 2008 issue of Nature. I strongly suggest that, if you haven't read it and have access to it, that you take some time reading it. It deals with the issue of the "transition" or boundary or crossover or whatever between classical and quantum regimes.

To understand what the quantum–classical transition really means, consider that our familiar, classical world is an ‘either/or’ kind of place. A compass needle, say, can’t point both north and south at the same time. The quantum world, by contrast, is ‘both/and’: a magnetic atom, say, has no trouble at all pointing both directions at once. The same is true for other properties such as energy, location or speed; generally speaking, they can take on a range of values simultaneously, so that all you can say is that this value has that probability. When that is the case, physicists say that a quantum object is in a ‘superposition’
of states.

Thus, one of the key questions in understanding the quantum–classical transition is what happens to the superpositions as you go up that atoms-to-apples scale? Exactly when and how does ‘both/and’ become ‘either/or’?

Of course, there is a very good coverage of the leading candidate that tries to connect between the classical-quantum transition - decoherence. One of the important point of the article is the idea that it isn't the SIZE of the object that is important, but rather the time scale for when decoherence sets in.

Decoherence also predicts that the quantum–classical transition isn’t really a matter of size, but of time. The stronger a quantum object’s interactions are with its surroundings, the faster decoherence kicks in. So larger objects, which generally have more ways of interacting, decohere almost instantaneously, transforming their quantum character into classical behaviour just as quickly. For example, if a large molecule could be prepared in a superposition of two positions just 10 ångstroms apart, it would decohere because of collisions with the surrounding air molecules in about 10−17 seconds. Decoherence is unavoidable to some degree. Even in a perfect vacuum, particles will decohere through interactions with photons in the omnipresent cosmic microwave background.

So that's why we can still get interference pattern when particles as large as buckyballs are used, or that we can still see superposition effects in 10^11 particles, as in the SQUID experiments from Delft/Stony Brook.

The article also pointed out the alternative idea from Penrose that the coupling of the system to gravity (or gravitons to be exact) might be responsible for the emergence of our classical observation. I mentioned this earlier in another blog entry, including the upcoming tests being proposed Dirk Bouwmeester.

A great article, even if only for the wealth of the references given. A highly-recommended reading.

PRST-AB Celebrates Its 10th Anniversary

The Physical Review Special Topics - Accelerators and Beams journal celebrates its 10th Anniversary on May 14th, 2008. Here is the announcement from the Physical Review

On 14 May 2008, Physical Review Special Topics - Accelerators and Beams is celebrating its 10th anniversary. PRST-AB was founded by Robert Siemann and the APS in 1998 to provide the accelerator community with its own journal, covering all aspects of accelerators from fundamental physics to technology. PRST-AB has also been an innovator in scientific publishing, with numerous advanced and novel features: It is an all-electronic journal, features conference or special editions, exhibits aspects of a virtual journal, and has pioneered open-access publication. PRST-AB is offered at no cost to both authors and readers, through the generous support of its sponsors.

Publications in PRST-AB have been growing steadily from initially 24 articles in 1998 to 130–140 articles published per year in 2006/7. In parallel, the number of sponsors has increased substantially from 8 original ones to presently 19, in North America and Europe. The wide sponsorship is recognition of 1) PRST-AB as the premier journal of accelerator physics and technology, and 2) the contributions PRST-AB is making to the international accelerator community.

To celebrate its 10-year milestone, PRST-AB is publishing a number of short essays on general topics of accelerator physics, written by well-known experts in the field. The anniversary essay series starts in May and will be continued throughout the remainder of this year.

Frank Zimmermann
Editor

Note that you can access articles from PRST-AB free of charge. With the announced publication of short essays on the general topics of accelerator physics, you might want to check out this journal during the remainder of the year for these articles. They might provide useful information and overview of the field if you're not familiar with the area of accelerator physics.

A Historical Derivation of Heisenberg’s Uncertainty Relation is Flawed

This is a rather interesting paper published in the current issue of AJP[1]. It narrates the historical account of the rigorous derivation of Heisenberg's uncertainty principle and claims that some of the derivation used after Heisenberg's presentation of it may have been flawed.

However, what caught my eye was the single author of this paper. It is John. H. Marburger III. When I checked his affiliation, I was correct. This is THE John Marburger who is currently the embattled "Science Adviser" to President's George W. Bush.

Immediately, 2 things came to my mind. First, at least he still gets to continue to explore scholarly topics, even in the historical sense, while he holds this position. But secondly, he must be bored in his current job to actually have some time to do such in-depth research. :) That last comment, of course, is purely speculative on my part.

At Ten, Dark Energy "Most Profound Problem" in Physics

I'm sure many people would argue with the "most profound problem" in physics tag here. But don't kill me, that's the title used in a rather good overview published by National Geographic of dark energy as it approaches its 10th year since discovery.

I've already mentioned other reviews and historical perspective on dark energy, which you may want to read here and here to supplement this article.

Willis E. Lamb Jr., Died at Age of 94

Anyone who has studied quantum mechanics would have come across his name and the "Lamb shift" named after him. Willis Lamb died this past week at the age of 94.

A professor emeritus at the University of Arizona, Dr. Lamb received a 1955 Nobel Prize in physics for his experimental work on the fine structure of the hydrogen atom and for the discovery of what came to be called "the Lamb shift," a tiny deviation in the energy of an electron orbiting a hydrogen atom's nucleus. The discovery had enormous implications for the quantum theory of matter.

Iron-Based High-Tc Superconductors - Follow-up

Actually, this is more of an in-depth review of what we know so far about this iron-based superconductors. Physics Today has quite a good article covering what has now become a rather "hot" material in condensed matter physics. It definitely appears that the spin-density wave has a major role in this family of material.

Arsenic Poison Didn't Kill Napoleon

Another myth bites the dust.

A new study by physicists at INFN in Milano-Bicocca and Pavia, Italy, has shown that there's no difference in the arsenic level in Napoleon's hair during his last days when compared to when he was a child. This means that he wasn't deliberately poisoned by arsenic during his last days. Instead, it was more likely that it was due to a lifetime's worth of exposure to arsenic.

Accelerator Disaster Scenarios, the Unabomber, and Scientific Risks

I just want to say that I had a lot of fun reading this preprint by Joseph Kapusta. It is entertaining, insightful, and has a ton of information for both scientists and non-scientists alike. It reinforces the point that I've been trying to make, which is the constant miscommunication between scientists and non-scientists. The blame goes on both sides - scientists for not considering how what they say is being interpreted by the public, and the public for not self-educating themselves into trying to understand not just the science, but the vocabulary that science uses. Not being aware that there are discontinuity in the communications and understanding of the two parties is the first significant problem. This is also a very good opportunity to again highlights the wonderful essay written by Helen Quinn that I've mentioned a while back. Everyone should read it!

If you have some time, I'd recommend reading this article by Kapusta, even for just for its "storytelling" aspect.
