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 […]

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.

As it was, for most of the day, I could barely keep on top […]

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 […]
