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

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

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
