I've been reading this and it's fantastic - approaching the subject from the tools needed to understand the way the material works mathematically (Lagrangians etc) rather than as a series of separate physical problems is an excellent idea.

The video lectures in combination with the text would, I think, be a great subject for a regular meet up - its dense enough that there's lots to discuss but doesn't have too many prereqs. Anyone in London interested? Shoot me an email if so (Thomas dot m dot McGrath at gmail dot com)
