    IceCube Search for Extremely High-energy Neutrinos Contributes to Understanding of Cosmic Rays

    Neutrinos are chargeless, weakly interacting particles that are able to travel undeflected through the cosmos. The IceCube Neutrino Observatory at the South Pole searches for the sources of these astrophysical neutrinos in order to understand the origin of high-energy particles called cosmic rays and,… Read More

    Twisted Light Gives Electrons a Spinning Kick

    It’s hard to tell when you’re catching some rays at the beach, but light packs a punch. Not only does a beam of light carry energy, it can also carry momentum. This includes linear momentum, which is what makes a speeding train hard to… Read More

Nathaniel Fisch, Princeton University
March 8, 2011 

And what are some useful things that it can be used for? This talk will explore how the simplest of waves in plasma can be used, among other things, to drive mega-amps of current, to divert mega-watts of power, or to mediate the next generation of laser intensities.
