Tidbits.

First, I have a guest post on the Houston Chronicle's science blog today.  Thanks for the opportunity, Eric.

Second, here is a great example of science popularization from the BBC.  We should do things like this on US television, instead of having Discovery Channel and TLC show garbage about "alien astronauts" and "ghost hunting".

Third, if you see the latest Sherlock Holmes flick, keep an eye out for subtle details about Prof. Moriarty - there's some fun math/physics stuff hidden in there (pdf) for real devotees of the Holmes canon.
