TASI 2008 Presentation Videos

garrettlisi tipped off twitter about presentation videos from the month-long Theoretical Advanced Studies Institute lecture series. It's available online here, the last presentations just finishing up and already online today.

I've started watching them and although they're quite technical, I can at least take away a little bit of knowledge from each one. I tend to look up terms as I watch and one that sparked my interest was 'rescattering' as used in the first lecture. Lots of results on the web for rescattering effects but I can't find any that list a definition of rescattering. Can anyone supply one in the comments?
