The Physics of Osmos: AAPT Winter Meeting Presentation

Here's the video presentation from the AAPT Winter Meeting.  Sorry, but there's no audio here - this is the video that played as I gave the talk, but it speaks for itself in some ways.  I'd love to add more, but my schedule says that it probably won't happen!

The image should link to a public file in my SugarSync account - please let me know if you can't access it!
