The Rayleigh-Taylor instability–typically marked by mushroom-shaped plumes–occurs when a dense fluid accelerates into a less dense one. But researchers have now demonstrated the effect at quantum scales, too. For their experiment, the group used a Bose-Einstein condensate of sodium atoms …
I’m trying to not get distracted from finishing writing up notes on some new ideas about Wick rotation, but here’s some news from Vichy-on-Hudson. Jonathan Cole, who was provost from 1989 to 2003, has written an excellent letter to the …
Some parasitic nematodes are known to propel themselves explosively into the air to land on their insect prey. A new study by UC Berkeley and Emory University biologists and physicists suggests that they’re not just blindly leaping into the unknown, …
In April 1969, Physics Today published a photograph of the American Physical Society’s 1932 banquet at the Ambassador Hotel in Atlantic City. The striking group portrait, dense with faces, was paired with an open call to readers: How many diners …
