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…

Uncertain Dots, Academic Blogs

Last week, a comment I made on Twitter about the annoyance of doing merit evaluation paperwork led to some back-and-forth with Rhett Allain and the National Society of Black Physicists Twitter account about whether blogs can or should count toward academic evaluation. This seemed like a good topic for another video hangout with me and…

Physics Hangout in Need of Better Title

What with the umpteen zillion articles declaring the Death of the Blog, I’ve been toying with the idea of doing something podcast-ish for a while. Rhett Allain from Dot Physics was game, too, and suggested using Google+ to do a video hangout, so here we are talking about our classes this term: The video quality…

A Brief Musical Interlude

Kate is off at Arisia this weekend, so I took the kids to Grandma and Grandpa’s. Where we’ve had good fun sledding and playing with a variety of toys. I’ll be driving home Sunday afternoon, and my parents will be bringing the kids back on Monday, which is the MLK holiday in the US, so…

One of the labs we do in the introductory E&M class I’m teaching this term involves investigating charged particles with sticky tape. If you haven’t seen it before, “invisible” tape picks up an electric charge when it’s peeled off a surface quickly, and with a little care, you can create both positively and negatively charged…
