Entangled in Sports Analogies

Having written in defense of analogies in physics yesterday, I should note that not all of the analogies that are brought out in an attempt to clarify physics concepts are good. For example, there’s this incredibly strained opening to a Science News article on entanglement: If the Manning brothers were quantum physicists as well as… Continue reading Entangled in Sports Analogies

Congratulations to Heck, Negishi, and Suzuki

The Nobel Prize in Chemistry for 2010 goes to Richard F. Heck, Ei-ichi Negishi and Akira Suzuki for giving people a reason to care about palladium. OK, it might not be the only reason– I’m not actually sure what palladium is used for other than organic synthesis and cold fusion– but it’s the context in… Continue reading Congratulations to Heck, Negishi, and Suzuki

Congratulations to Andre Geim and Konstantin Novoselov

The 2010 Nobel Prize in Physics goes to Geim and Novoselov for their work on graphene, a material consisting of one-atom-thick sheets of carbon atoms in a hexagonal array. This is one of those prizes that was basically inevitable, as graphene is one of the hot materials of the last couple of years. Hardly a… Continue reading Congratulations to Andre Geim and Konstantin Novoselov

Simple Answers to Complex Medical Questions

There’s a new medical study of the effects of alcohol consumption that finds a surprising result: Controlling only for age and gender, compared to moderate drinkers, abstainers had a more than 2 times increased mortality risk, heavy drinkers had 70% increased risk, and light drinkers had 23% increased risk. A model controlling for former problem… Continue reading Simple Answers to Complex Medical Questions

Quantum Mechanics Is Square: “Ruling Out Multi-Order Interference in Quantum Mechanics”

This week’s big story in physics is this Science paper by a group out of Austria Canada (edited to fix my misreading of the author affiliations), on a triple-slit interference effect. This has drawn both the usual news stories and also some complaining about badly-worded news stories. So, what’s the deal? What did they do… Continue reading Quantum Mechanics Is Square: “Ruling Out Multi-Order Interference in Quantum Mechanics”

Launch Pad for Quantum Physics

Over at Jeff Vandemeer’s blog, Rachel Swirsky has a series ofm guest posts (start here if you prefer direct post links) about the recently completed Launch Pad workshop. this is a NASA funded workshop bringing a group of writers together for six days of lectures on modern astronomy from working astronomers. From the workshop web… Continue reading Launch Pad for Quantum Physics

Dorky Poll: Accelerator Slap-Fight

Rumors that the Tevatron at Fermilab may have discovered the Higgs boson have escaped blogdom to the mainstream media. This originates in a blog post by Tommaso Dorigo, which I can’t read because it doesn’t display properly in Firefox, but I’m sure is very interesting. Anyway, this is a good excuse for a dorky poll:… Continue reading Dorky Poll: Accelerator Slap-Fight

Big News in Tiny Physics

A couple of significant news items from the world of particle physics: There was a conference on neutrino physics recently, and the big news from there is that two experiments measure something funny with neutrino oscillations, namely that the oscillations seem to proceed at different rates for neutrinos and antineutrinos. This is a really surprising… Continue reading Big News in Tiny Physics

Photons: Still Bosons

Last week, Dmitry Budker’s group at Berkeley published a paper in Physical Review Letters (also free on the arxiv) with the somewhat drab title “Spectroscopic Test of Bose-Einsten Statistics for Photons.” Honestly, I probably wouldn’t’ve noticed it, even though this is the sort of precision AMO test of physics that I love, had it not… Continue reading Photons: Still Bosons

Scientific Salary Stratigraphy: Past Performance Does Not Guarantee Future Results

Inside Higher Ed has a news squib about gender disparities in academic science, which points to a Nature story about a survey on job satisfaction (bad IHE, giving a false impression on the story!). The gender portion of the story is limited to a short section at the end of the article, and one graph:… Continue reading Scientific Salary Stratigraphy: Past Performance Does Not Guarantee Future Results
