[quote]“The Royal Swedish Academy of Sciences has decided to award the 2015 Nobel Prize in Physics to Takaaki Kajita and Arthur B. McDonald for the discovery of neutrino oscillations, which shows that neutrinos have mass.” Göran Hansson, secretary general of the academy, a few minutes before 6am Eastern time. Kajita is at the University of Tokyo. McDonald is with Queen’s University in Kingston, Canada. “At this moment in this room there are more than a billion neutrinos, which travel almost at the speed of light.”[/quote] [url]http://www.scientificamerican.com/podcast/episode/2015-nobel-prize-in-physics/[/url] Well-deserved. A well-known, experimentally-verified result which is not yet understood theoretically and shows the incompleteness of the Standard Model.
I don't understand physics so I'm just going to say; good.
Re-enable ratings so I can give this a million winners These two have very much earned this prize

Go science

Fantastic result, elegantly done. Congrats to them.

This year’s prize is awarded to the experimental discovery that neutrinos can change identity. For example, a mu-neutrino can become a tau-neutrino and vice versa. They oscillate.[/QUOTE]
Is this in anyway related to the theory not to long ago that neutrinos can go FTL? I seem to remember something about neutrino oscillations as a potential explanation.
[QUOTE=LoneWolf_Recon;48840917]Is this in anyway related to the theory not to long ago that neutrinos can go FTL? I seem to remember something about neutrino oscillations as a potential explanation.[/QUOTE] That turned out to be loose wiring. Neutrinos don't go FTL.

[QUOTE=Hamaflavian;48841372]transneutrino joke incoming[/QUOTE] Mmhh... I have a joke on the tip of my tongue about Neutrinos being able to go FTM but not FTL yet I cannot come with anything witty. God this is frustrating.
Interesting video about it. [video=youtube;XQHw7qQrpf0]http://www.youtube.com/watch?v=XQHw7qQrpf0[/video]

Excuse my ignorance, I don't know physics well.. if at all.
[QUOTE=Fourier;48841944]So this means something Tesla could be right about Aether? Other type neutrinos from nature can be changed to electron-neutrinos - electricity?

[QUOTE=Falubii;48842250]Electricity is electric fields. Neutrinos are electrically neutral.[/QUOTE] Oh ok. But why Electron Neutrino then.. do those Electron Neutrino share properties with Electrons.. mass wise or what? Just wondering.
[QUOTE=Fourier;48843263]Oh ok. But why Electron Neutrino then.. do those Electron Neutrino share properties with Electrons.. mass wise or what? Just wondering.[/QUOTE] They're part of the same lepton generation. Muon and mu neutrino, electron and electron neutrino, tau and tau neutrino.

Just wondering.[/QUOTE] In nuclear reactions, whenever an electron is produced, you get an electron neutrino along with it, hence the name. I don't know of any reactions that make muons or taus, but the same probably applies. They're just named after the other particle they're associated with.

It seems they would be necessary if we wanted to run one of those reactions in reverse.

all i know is as long it breaks the standard model of physics, we are in the right direction of things.
