I thought I had mentioned it on Twitter enough, but as several people were surprised to see me last night, it’s probably worth saying more prominently: I’m at the Science Online 2013 conference in Raleigh, NC this week. This is making me tremendously popular with my class, who are taking an exam tonight… Anyway, if… Continue reading Science Online

Cute Kid Update
It’s been a good while since I did any Cute Kid Blogging, due to excessive busy-ness. There’s big news among the younger residents of Chateau Steelypips, though: SteelyKid lost one of her front teeth the other day: That gap? Wasn’t there on Friday morning. Lest you think we’re horrible people who let her run headfirst… Continue reading Cute Kid Update
Physics Is About Rules, Not Facts
While in the library looking for something else, I noticed a book called The Trouble with Science by Robin Dunbar, whose description made it sound very much on point for my current project: In The Trouble with Science, Robin Dunbar asks whether science really is unique to Western culture, even to humankind. He suggests that… Continue reading Physics Is About Rules, Not Facts
Blast From the Past: Letter to and From Luis Alvarez
I have mentioned before that when I was a kid, I wrote a letter to Luis Alvarez, the 1968 Nobel laureate in Physics, asking some questions about his theory that an asteroid impact killed the dinosaurs, which had been featured in a NOVA special. I got a very nice letter back from him, very graciously… Continue reading Blast From the Past: Letter to and From Luis Alvarez
Proving Bethe Wrong: On Theory Inspiring Experiment
As research for the work-in-progress, I recently read Luis Alvarez‘s autobiography, Alvarez: Adventures of a Physicist, which contains a passage that I was reminded of last night while reading another book, that seems like an amusing follow-up to yesterday’s rant about theory and experiment. This is from the end of the chapter where he joined… Continue reading Proving Bethe Wrong: On Theory Inspiring Experiment
Experiments Are Not Afterthoughts
There’s been a bunch of talk recently about a poll on quantum interpretations that showed physicists badly divided between the various interpretations– Copenhagen, Many-Worlds, etc.– a result which isn’t actually very surprising. Sean Carroll declares that the summary plot is “The Most Embarrassing Graph in Modern Physics, which I think is a bit of an… Continue reading Experiments Are Not Afterthoughts
How Do You Make Negative Temperatures, Anyway?
Last week’s post talked about the general idea of negative temperature, with reference to this much-talked-about Science paper (which also comes in a free arxiv version from which the figures used here are taken). I didn’t go into the details of how they made a negative temperature gas, though, and as it’s both very clever… Continue reading How Do You Make Negative Temperatures, Anyway?
What Does “Negative Temperature” Mean, Anyway?
The most talked-about physics paper last week was probably Negative Absolute Temperature for Motional Degrees of Freedom (that link goes to the paywalled journal; there’s also a free arxiv preprint from which the above figure is taken). It’s a catchy but easily misinterpreted title– Negative absolute temperature! Below Absolute Zero! Thermodynamics is wrong!– that obscures… Continue reading What Does “Negative Temperature” Mean, Anyway?
The Psychology and Improbability of Shuffle Play
Kate and I went down to New York City (sans kids, as my parents were good enough to take SteelyKid and The Pip for the weekend) this weekend, because Kate had a case to argue this morning, and I needed a getaway before the start of classes today. We hit the Rubin Museum of Art,… Continue reading The Psychology and Improbability of Shuffle Play
Faitheist by Chris Stedman
I started following Chris Stedman on Twitter thanks to a recommendation from Josh Rosenau citing him as someone who promotes atheism without being contemptous of religious people. He was, indeed, a source of religion-and-politics material that I found congenial, and when I noticed he was flogging a forthcoming book, I picked up a copy, which… Continue reading Faitheist by Chris Stedman
