Several people blogged about a new measurement of gravitational states of neutrons done by physicists using ultracold neutrons from the Institut Laue-Langevin in France. I had to resort to Twitter to get access to the paper (we don’t get Nature Physics here, and it’s way faster than Inter-Library Loan), but this is a nice topic… Continue reading Bouncing Neutrons for Fun and Science: “Realization of a gravity-resonance-spectroscopy technique”

The Status of Simulations
Most of what would ordinarily be blogging time this morning got used up writing a response to a question at the Physics Stack Exchange. But having put all that effort in over there, I might as well put it to use here, too… The question comes from a person who did a poster on terminology… Continue reading The Status of Simulations
Protons: Even Smaller Than We Thought
The big physics story at the moment is probably the new measurement of the size of the proton, which is reported in this Nature paper (which does not seem to be on the arxiv, alas). This is kind of a hybrid of nuclear and atomic physics, as it’s a spectroscopic measurement of a quasi-atom involving… Continue reading Protons: Even Smaller Than We Thought
