People seem to want to learn more about neutrinos! With the latest Nobel prize being awarded to the discovery of neutrino mixing, it is a good time to have some general article on what we know about neutrinos. John Beacom has written a rather nice article here that should give you an idea of the physics of neutrinos and why it is an important study.
It just struck me as a rather interesting development. When SNO and Super-K were discovering all this, there was hardly any neutrino experiment in the US. Oh, there was plenty of US participation, but neutrino experiments were not big or a priority. This is understandable because, back then, the Tevatron was still going strong and LHC hasn't completely come into force yet. Now, how things have changed considerably. With the Tevatron gone and the center of high energy physics collider having shifted to CERN, the US is now trying to be a major player in neutrino studies, with MINOS, NOvA, and the proposed LBNE. In DOE/funding lingo, the US has abandoned the "Energy Frontier" and has gone into the "Intensity Frontier".
I believe there are still huge amount of amazing physics to be discovered from neutrinos. So it will be interesting how all these new generation of neutrino detectors will pan out.
