I had hoped to have another post or two scheduled for the end of this week, but The Pip got some kind of stomach bug, and threw everything into disarray. And tonight, I’m flying to Houston to give a couple of talks as part of Physics Day at Space Center Houston. Life being what it… Continue reading Messing With Texas

SteelyKid Demonstrates Relativity
Before going to the playground Saturday to investigate non-intertial frames, SteelyKid and I went over to campus to do some experiments in relativity. Galileian relativity, that is: What you see here is SteelyKid sitting on a rolling lab cart with a camera bolted to it. She throws a ball up in the air a couple… Continue reading SteelyKid Demonstrates Relativity
Non-Inertial Playground Physics
The Schenectady JCC, where SteelyKid and The Pip go to day care, has a playground with a merry-go-round on it. How this hasn’t been sued out of existence, I have no idea, but it’s a great boon to a physics professor. I’ve used it before to talk about angular momentum, but this weekend I enlisted… Continue reading Non-Inertial Playground Physics
Cosmos and the Women
Back when the first episode of the Cosmos reboot aired, somebody put together a composite of the cartoon people who flashed on screen, and we played a guessing game on Twitter. The image above is from a blog post by Meg at True Anomalies, and I think it was probably her, but the ephemeral nature… Continue reading Cosmos and the Women
Great Moments in Puzzling Axis Labels
While I’m complaining about statisticulation in social media, I was puzzled by the graph in Kevin Drum’s recent post about college wage gaps, which is reproduced as the “featured image” above, and also copied below for those reading via RSS. I don’t dispute the general phenomenon this is describing– that the top 10% of college… Continue reading Great Moments in Puzzling Axis Labels
Flame Challenge Finalists 2014: What Is Color?
The finalists for the 2014 “Flame Challenge” have been selected, three written entries and three visual entries. None of these is my entry, alas, but it was worth a shot. I watched the videos last night, and it was sort of interesting to compare what ended up working well with the test audience of 11-year-olds… Continue reading Flame Challenge Finalists 2014: What Is Color?
String Experiment: Capillary Action is Complicated
As I’ve mentioned here before, I do a lot of work these days in my local Starbucks. This is slightly ironic, as I don’t like coffee– instead, I order tea, which I put in an insulated travel mug. I tend to get the tea, carry the mug back to the table, and let it steep… Continue reading String Experiment: Capillary Action is Complicated
Uncertain Dots, Episode 12
The last couple of days have been ridiculously hectic, but Rhett and I did manage to record another episode of Uncertain Dots, our twelfth: This time out, we talk about labs, undergrad research, kids doing chores, weather, student course evaluations, and I didn’t really rant about superheroes. Relevant to the weather thing, I offer the… Continue reading Uncertain Dots, Episode 12
Superheros are Anti-Science
I’m not really a comic-book guy, but I’ve watched a bunch of comic-book movies recently. Kate was really fired up for the new Captain America movie, so I finally got around to watching the first one as background for that, then when I was sleep-deprived last week I watched the second Thor movie via on-demand… Continue reading Superheros are Anti-Science
Cosmos Reboot Gets Small
A diabolical psychologist brings a mathematician in for an experiment. The mathematician is seated in a chair on a track leading to a bed on which there is an extremely attractive person of the appropriate gender, completely naked. The psychologist explains “This person will do absolutely anything you want, subject to one condition: every five… Continue reading Cosmos Reboot Gets Small
