I worked on SNO for my masters, helping to build the water purification systems. The goal was one atom of impurity per cubic metre of water. It made distilled water look filthy. :)<p>Everyone knew that if we got it to work, Arthur would win the Nobel Prize. He worked <i>very</i> hard on it, and was a good leader.<p>Congratulations to him.
I can't wait to see laureates' Nobel Lectures. Each year laureates give a down to earth lecture about their findings - how they started, how they found the results, what motivated them to work on these problems, etc. Very interesting to see laureates explain this themselves.<p>Click on the laureate names, then choose "Nobel Lecture" to watch the videos.<p>For example,<p><a href="http://www.nobelprize.org/nobel_prizes/physics/laureates/2013/higgs-lecture.html" rel="nofollow">http://www.nobelprize.org/nobel_prizes/physics/laureates/201...</a><p>For Higg's lecture a few years ago, etc.
<a href="https://en.wikipedia.org/wiki/Neutrino_oscillation" rel="nofollow">https://en.wikipedia.org/wiki/Neutrino_oscillation</a><p>Neutrino oscillation is a quantum mechanical phenomenon whereby a neutrino created with a specific lepton flavor (electron, muon or tau) can later be measured to have a different flavor. The probability of measuring a particular flavor for a neutrino varies periodically as it propagates through space.<p>First predicted by Bruno Pontecorvo in 1957,[2] neutrino oscillation has since been observed by a multitude of experiments in several different contexts. Also, it turned out to be the resolution to the long-standing solar neutrino problem.<p>Neutrino oscillation is of great theoretical and experimental interest, since observation of the phenomenon implies that the neutrino has a non-zero mass, which was not included as part of the original Standard Model of particle physics.
Quote from the embedded video:<p>> In order to do this we had to build a detector the size of a 10 story building, 2 kilometers underground. In a mine, Creighton Mine, near Sudbury, Ontario... and we had the advantage of a thousand tonnes [of heavy water] on loan from Canada's reserves of heavy water. The value of which was on the order of 300 million dollars. We used that for about 10 years, measuring neutrinos roughly 1 [per] hour. By having this very sensitive detector we were able to make measurements that others could not. But it took [a] team... on the order of 150 people to accomplish this scientific measurement.<p>Pretty astounding work, if you ask me. The dedication of these people should be applauded.
This seems to be awards for two neutrino observatories, Super-Kamiokande and SNO(Sudbury Neutrino Observatory). Note that the Nobel Prize in Physics 2002 was also awarded to neutrino observations.
Is it fair to give the Nobel prize to a single/two persons in 2015? Usually it is a team of people all working together collectively to solve a common problem.
We changed the URL from <a href="http://www.nobelprize.org/nobel_prizes/physics/laureates/2015/index.html" rel="nofollow">http://www.nobelprize.org/nobel_prizes/physics/laureates/201...</a> to one that gives some background.
OT: In spanish Kajita sounds like Cajita (little box), so there's a joke about this being a PR campaing of McDonalds.<p>Also Kajita should be happy because of this achievement :P
