A lot of Twitter energy was soaked up Friday afternoon by a half stupid article by Virginia Heffernan at the New York Times. Sparked by Sodamageddon, she takes a look at ScienceBlogs for the first time, and doesn’t like what she sees: Hammering away at an ideology, substituting stridency for contemplation, pummeling its enemies in… Continue reading The Heffernan Conundrum

Reader Request: Quantum Complexity
There’s some good stuff in yesterday’s post asking what physics you’d like to read more about. I’m nursing a sore neck and shoulder, so I’ll only do one or two quick ones today, starting with James D. Miller in the first comment: 1) Is it true that our understanding of quantum physics comes from studying… Continue reading Reader Request: Quantum Complexity
Should Doctors Have to Take Physics and Chemistry?
The New York Times today has a story with the provocative title Getting Into Med School Without Hard Sciences, about a program at Mount Sinai that allows students to go to med school without taking the three things most dreaded by pre-meds: physics, organic chemistry, and the MCAT: [I]t came as a total shock to… Continue reading Should Doctors Have to Take Physics and Chemistry?
When Should You Open Your Car Windows? An Experiment
Back at the start of the summer, I asked a question about automotive thermodynamics: On a hot day, is it better to open your car windows a crack when making a short stop, or leave them closed? For a long term– say, leaving your car parked outside all day– I hope everyone will agree that… Continue reading When Should You Open Your Car Windows? An Experiment
Measuring Temperature by Counting Atoms: “Suppressed Fluctuations in Fermi Gases”
When one of the most recent issues of Physical Review Letters hit my inbox, I immediately flagged these two papers as something to write up for ResearchBlogging. This I looked at the accompanying viewpoint in Physics, and discovered that Chris Westbrook already did most of the work for me. And, as a bonus, you can… Continue reading Measuring Temperature by Counting Atoms: “Suppressed Fluctuations in Fermi Gases”
Electron Spin for Toddlers
The subject of the “spin” of the electron comes up again and again, so as pointed out in a comment, I really ought to do a post explaining what it is and how it works. As a bonus, this gives me the opportunity to do the dorkiest thing anyone has ever done with a cute-toddler… Continue reading Electron Spin for Toddlers
Dinosaurs Are Too Easy
Earlier this week, there was some interesting discussion of science communication in the UK branch of the science blogosphere. I found it via Alun Salt’s “Moving beyond the ‘One-dinosaur-fits-all’ model of science communication” which is too good a phrase not to quote, and he spun off two posts from Alice Bell, at the Guardian blog… Continue reading Dinosaurs Are Too Easy
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”
Why Would Anybody in Their Right Mind Build the LHC?
In the comments following the silly accelerator poll, onymous wrote: [T]he point of the LHC isn’t to discover the Higgs. No one in their right minds would build a 14 TeV pp collider if their only goal was to discover the Higgs. While it’s true that the ultimate goal of the LHC is to discover… Continue reading Why Would Anybody in Their Right Mind Build the LHC?
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
