For nearly a century, physicists have relied on the Born rule to calculate the chances of different outcomes when they measure a quantum system. Yet despite decades of effort, nobody has managed to derive the rule from more basic mathematical principles without making assumptions about probability a...

Glimpses of the "gallium anomaly" were first seen in the mid-1990s, but it was first clearly discovered and stated in 2007 by neutrino physicist Carlo Giunti of Italy. The problem is simple to state but potentially very important: about 20% fewer electron neutrinos were seen to be captured by galliu...

Rest in peace!

The Physics Department is very sorry to report that our colleague Jeffrey Goldstone, Cecil and Ida Green Professor Emeritus of Physics, died on October 12 at the age of 93. Jeffrey began his career as a nuclear theorist. He earned his PhD from Trinity College, Cambridge in 1958 and did postdoctoral....
