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”

The Western Undergraduate Problem
A few years ago, we ended up trading some classroom space in the Physics part of the building to Psychology, which was renovated into lab space for two of their new(ish) hires. This turned out to be a huge boon not only for the department (the lab space we got in the swap is really… Continue reading The Western Undergraduate Problem
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
How to Teach Physics to Your Japanese Dog
The vanity search this morning turned up something I hadn’t seen before: That’s the Japanese edition of How to Teach Physics to Your Dog. I knew one was in the works, but hadn’t heard when it would be out. Of course, I can’t read any of it other than my own name (rightmost column of… Continue reading How to Teach Physics to Your Japanese Dog
Not Everything Is About CO_2
Climate change is a major crisis, don’t get me wrong, and it’s something that needs to be discussed extensively in both scientific and policy circles. We’re pumping carbon dioxide into the atmosphere at rather too high a rate, and getting something done about that is a key priority. It’s possible, though, to take the obsession… Continue reading Not Everything Is About CO_2
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”
Real Math Doesn’t Use Calculators
The Dean Dad is worried about remedial math: In a discussion this week with someone who spends most of her time working with students who are struggling mightily in developmental math, I heard an argument I hadn’t given much thought previously: students who have passed algebra and even pre-calc in high school frequently crash and… Continue reading Real Math Doesn’t Use Calculators
Sex, Intuition, and Evidence in Science
Over at A Most Curious Planet, Alexandra Jellicoe offers a story with the provocative headline Is Science Sexist?, which spins off an anecdote from astronomy: I was listening to Radio 4 a few months ago and the discussion about gender intelligence lodged in the deeper recesses of my brain unthought-of until recently when I went… Continue reading Sex, Intuition, and Evidence in Science
Backyard Fluid Dynamics
Here’s a picture of the ornamental pond we have in our back yard, showing the fountain that we run to keep the water circulating so it’s not just a mosquito ranch: You can see the brick that we have sitting on top of the pump housing to keep it submerged (it tends to tip over… Continue reading Backyard Fluid Dynamics
