Lazy Reporting And Taking Way Too Much Credit

It is not surprising that whenever a major discovery is made or a major award is given, as many people and institutions want to ride the coattail and be a part of it. I understand that.

But sometime, it is stretching it a bit waaaay too much, especially when the report itself sounds very lazy and weak.

The recent announcement of the Nobel Prize in physics being awarded to 3 figures who are instrumental in the discovery of gravitational waves seem to be one such case. I stumble across this news article out of what I believe is a local newspaper called the "Gonzales Weekly Citizen". The headline said:

LSU scientists win Nobel Prize in Physics

Of course, that perked my interest since I didn't know any of the 3 men who were awarded the prize are known to be associated with LSU (Louisiana State University, for those who are not familiar with this).

Now, it seems that the reporter is playing fast and loose. Rainer Weiss is listed as an "adjunct professor" in the LSU physics dept. Now, we all know that an adjunct professor is nothing more than a "contractor". That person is not considered as a staff member, but rather hired on a per-term basis or based on a contract. In most cases, the person is probably associated by another institution rather than the one where he/she is an adjunct professor of.

In fact, in this case, Rainer Weiss is more well-known as being associated with MIT than anywhere else. It is what is listed in all the news report for this award. In fact, if you look at the Nobel Prize page that announced this award, the profile on Weiss says:

Affiliation at the time of the award: LIGO/VIRGO Collaboration, Massachusetts Institute of Technology (MIT), Cambridge, MA, USA

No mention of LSU. In fact, the LIGO project itself is a consortium of many universities and it is jointly administered by MIT and Caltech. One of the facilities may be in Louisiana, and LSU is involved in the project, but that's about it. They should be proud of their contribution to the project, but to over play it to this level is not quite right.

So this news report is misleading at best!

But that's not all! There's a certain level of laziness in the reporting.

LSU adjunct professor and MIT professor Emeritus Rainer Weiss and California professor Emeritus Kip Thorne are co-founders of the collaboration. Weiss won half of the prize, and the other half went to the California Institute of Technology professors involved.

I'm sorry, but they could not even bother to mention Barry Barish name? He's being relegated to being part of the "... California Institute of Technology professors involved." REALLY!

As I said, rather lazy reporting.

Electron Is Still A Point Particle

There have been experiments to measure the electric dipole moment of an electron, if any, which would indicate that (i) an electron has an internal structure and (ii) consequently it isn't a point particle that we have been assuming within QED. So far, all the experiments have not found any, and each measurement continues to increase the precision of the previous measurement.

Chalk this one up to follow the same trend[1]. This time, they are using a different technique to measure the electron dipole moment by using trapped molecular ions. The result of the experiment is an even more precise measurement, and lowered the upper bound of the dipole moment by several orders of magnitude when compared to the previous result.

Electron is still a spherical cow!

2017 Physics Nobel Prize Goes To Gravitational Wave Discovery

To say that this is a no-brainer and no surprise are an understatement.

The 2017 Nobel Prize in Physics goes to 3 central figures that made LIGO possible and the eventual discovery of gravitational wave in 2015.

The Nobel Prize in Physics 2017 was divided, one half awarded to Rainer Weiss, the other half jointly to Barry C. Barish and Kip S. Thorne "for decisive contributions to the LIGO detector and the observation of gravitational waves".

Congratulations to all of them!
