Winter Thermodynamics: Foggy Glasses

We’re having a brutal cold snap at the moment, and while today’s early-morning dog walk was considerably warmer than yesterday’s, it was still 0F/-18C out, which is way colder than I like. When I came back in the house after the walk, my glasses instantly fogged up. But I had to take some stuff outside…

How Fast Is SteelyKid’s Nerf Gun?

SteelyKid is spending a couple of days this week at “Nerf Camp” at the school where she does taekwondo. This basically consists of a bunch of hyped-up kids in a big room doing martial activities– taekwondo class, board breaking, and “Nerf war” where they build an obstacle course and then shoot each other with dart…

Why Is Snow White?

It didn’t make the news, because skittish media types are mostly based in New York City and thus don’t care about anything north of Westchester County, but we had a big snow storm yesterday. It started snowing Sunday night, though, and kept up through pretty much dinnertime Monday. Both the local schools and the snow-day…

Deflategate on Discovery Canada

I know I said I was done with this story, but this was actually recorded last week: The Daily Planet show on Discovery Channel in Canada contacted me last week when all this deflated-football silliness was exploding, and got a cameraman to come over and record me talking about it. The episode aired Monday night,…

Deflategate: The Final Chapter

The low-level cold I’ve been nursing for a month now finally exploded into the full unpleasantness of my usual winter illness Saturday, or else I would’ve been more active following up on my Deflategate article and my ideal gas law post. As it was, for most of the day, I could barely keep on top…

So, as mentioned yesterday, I got an email asking me about the weird scandal involving the Patriots and underinflated footballs, so I wrote a piece for the Conversation on the subject. since a few people had beaten me to citations of the Ideal Gas Law, though, I decided to bring my own particular set of…

One of the cool things about working at Union is that the Communications office gets media requests looking for people to comment on current events, which sometimes get forwarded to me. Yesterday was one of those days, with a request for a scientist to comment on the bizarre sports scandal surrounding the deflated footballs used…

Thermal Thursday: How Good Is My Mug?

One of my favorite Christmas presents this year was a Seek Thermal camera to use with my Android phone. This allows for a lot of idle physics-y fun, taking pictures of things in thermal mode. One idea I had was to do a sort of follow-up to the test of my insulated mug that I…

Holiday Thermal Physics

One of my Christmas gifts this year was a Seek Thermal camera, so I can continue my transformation into Rhett Allain. What’s this for? Why, physics, of course. Such as this video of the operation of the Christmas pyramid my parents picked up in Germany, and had set up at the start of Christmas dinner:…

I’m teaching relativity in a course with an astronomy prefix, which means I’m obliged to talk about stars and stuff. Yesterday’s lecture was about neutron stars, and how their existence was confirmed by the discovery of pulsars (with the story of Jocelyn Bell Burnell included). This requires some discussion of angular momentum to explain how…
