I cross a threshold

What's new since the last post?

• I've finished taping the new course for the Teaching Company. Now all I have to do is finish the written materials -- a big job that I'm behind on, true, but a little less of a crisis. The course should be a fun one.
  
• A total of four "Friday Afternoon Physics" videos are up, including my favorite, Episode 4 (in which we blow things up). Episode 3 is on quantum physics, and it has some fun computer animations that I made.
  
• Mike and I have corrected the proofs of the new quantum mechanics textbook, which is supposed to be out in the US in March. We created the cover image, which was fun. It's a circular diffraction pattern. On one side, it fades into a scattering of discrete dots; on the other side, it turns into 1s and 0s.
  
• I gave a talk at a Theological Symposium sponsored by my brother's seminary. To make things weird, the whole thing is posted, in both audio and video formats, on iTunes U. So you can watch my lecture, and my brother's reply, there. This means I've officially crossed the threshold from "user" to "content provider" on iTunes.

I'm hoping all this means that I'll have some more time for blogging and other kinds of writing. The next post should get things going.
