Neutrinos: Nature's Identity Thieves?

The oscillation of neutrinos from one variety to another has long been suspected, but was confirmed only about 15 years ago. In order for these oscillations to occur, neutrinos must have a mass, no matter how slight. Since neutrinos have long been thought to be massless, in a very real way, this phenomena is a clear signal of physics beyond the known. In this video, Fermilab's Dr Don Lincoln explains how we know it occurs and hints at the rich experimental program at several international laboratories designed to understand this complex mystery.

This channel is one of the very few that explain complex subjects simply and clearly. Thanks, Don!

It's sad that your videos get so few views because they are really good and relatively easy to understand even for a layman like me. :)

[MyEdITz]

its sad that this channel doesnt get enough attention. they explain complex physics so simply but also accurately...

I'm oscillating between these wonderful fermilab videos!

[paiacinhu]

If even I understand that, this is a great teaching video, Dr. Lincoln.

Congrats and best wishes for everybody at Fermilab.

I mean, how do you even find 3 atoms among quadzilions other atoms?

[johnfial]

Great video and presentation -- keep up the good work!

Sadly, this bloke will never make it as a TV personality. It pains me to say that as he really does explain things incredibly well.

Great channel you explain things very clearly so that someone that doesn’t have any knowledge gained some knowledge from your expert anthology and way of delivering.

Where was this channel... So glad I found it

[yousufnazir]

Experimental results and the computational fluid dynamics of the particle spectrometry is very important for empirical research.

i real like your videos, your clear voice style speaking 
thank you Dr

[pixxelwizzard]

Fascinating video. It's presented so well, too. Thank you!

If neutrinos oscillate, how do they "remember their origins".

[photon_phi]

Could explain more solar neutrino deficit? And what is phototubes? And the SNO experiment?
please and thank for the information.

[Beer_Dad]

Thank you Dr Lincoln, always enjoy your videos.

[jayaramanganapathi]

Thank you Dr Don, have been waiting for these learnings.

Davis brought the term 'Brute Force' a whole new level

[Rationalific]

Okay, okay... So neutrinos oscillate and all. But the mind-blowing part is how humans are able to detect so few particles, such as argon atoms. That's insane how a few atoms (all of which were supposed to have been detected, otherwise the deficit would have been simply chalked up to not being able to detect the rest) can be detected in a giant vat!

[StarlessRogue]

Possibly a dumb question but... What is the difference between the 3 flavors of neutrinos? Like, how do they know they are seeing a Muon Neutrino vs an Electron Neutrino?
