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 …

Students and instructors in Physics I (8.01) discuss how AI has impacted how the class is taught Learning classical mechanics has long been a source of frustration for first-years at MIT. Even for those with high school experience in physics, …
📖Read Time: 7 minutes 📊Readability: Standard (High school level) 🔖Core Topics: itex, function, tex, linear, delta Introduction: “Convenient Notation” Approaching a Dirac delta function In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred …
Sunflowers are blooming, stores are trumpeting back-to-school sales, and professors are scrambling to chart out the courses they planned to develop in July. If you’re applying for an academic job this fall, now is the time to get your application …
Physics has 7 base units: seconds, metres, kilograms, amperes, kelvins, moles, and candela. Of those, we technically only need the first three to calculate the latter four. But according to a new paper, we can actually calculate the first three …
