What a Circus

Last weekend, the circus came to town, and Grandma and Grandpa came up to help us take the kids. We took SteelyKid a couple of years ago, and figured The Pip was old enough to go this time, too. Having bought tickets a couple of years ago, I got sent a pre-sale offer link, and…

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…

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…

Uncertain Dots, Episode 8

In which Rhett and I talk about Cosmos. What, you thought there would be another topic? We have contractual obligations, you know… Okay, there were some other topics like Battlestar Galactica (both versions), why so much of what’s on Discovery Channel and TLC sucks these days, the flawed astrophysics of Firefly, speculation about how those…

Uncertain Dots, Episode 7

In which we move out of the original trilogy, and into J.J. Abrams territory. Cue the lens flare! This week’s random assortment of topics includes travel, airports, physics models of loading and unloading planes, uses and abuses of curve fitting, odd stuff we get sent to review, and high-speed video cameras. Miscellaneous links: — Rhett’s…

What Is Color?

This year’s “Flame Challenge” asks scientists to explain color in terms an 11-year-old can understand. The rules limit answers to either 300 words of text or a 6-minute video. 300 words is ridiculously short, so video is clearly the way to go. Of course, I’m not much of a video expert, but then, one of…

Uncertain Dots, Episode 6

This week’s episode of Uncertain Dots is, if anything, even more free-form than previous weeks, including a brief cameo from one of Rhett’s kids: Topic covered include the arrangement of faculty offices, the relative lack of demos for E&M (compared to mechanics, where there are endless videos to analyze, etc.) a little bit about science…

Uncertain Dots, Episode 4

I didn’t advertise it heavily this time, but Rhett and I did another G+ hangout yesterday, and the video is online now: We talked for a while about the wonders and importance of VPython coding (including some “Oh, I should totally do that…” moments), where we get post ideas (including a discussion of luge physics),…

Follow the Bouncing Ball

Last week, Rhett did a post on animating a bouncing ball in VPython. This was mostly making a point about the distinction between real simulation and animation, along the lines of yesterday’s post on social construction of videogame reality. But, of course, my immediate reaction was, “That’s not how a bouncing ball looks…” This is…

Video Editing Software?

Both SteelyKid’s kindergarten and the snow-day day-care program that the kids go to were closed today, which kind of threw a wrench in things. But it’s also kind of fun, as I got to spend some time playing outside with SteelyKid on her play set in the snow. The “featured image” above is a cell-phone…
