How do you make a neutrino beam?

530 views / 0 likes - added 5 years ago

Neutrinos are notorious for not interacting with anything and yet scientists are able to make beams of neutrinos and point them in very specific directions, hitting targets many hundreds of miles away. In this video, Fermilab’s Dr. Don Lincoln explains th

The Weak Nuclear Force: Through the looking glass

459 views / 0 likes - added 5 years ago

Of all of the known subatomic forces, the weak force is in many ways unique. One particularly interesting facet is that the force differentiates between a particle that is rotating clockwise and counterclockwise. In this video, Fermilab’s Dr. Don Lincoln
