Game Physics 2nd

David Eberly who is one of the famous game related authors published a new book last month: Game Physic 2nd.
The book is based on Wild Magic new version, 5.1, according to the web page: http://www.geometrictools.com

I was wondering for a while what he was doing now. I haven't read the 1st edition, but I like to grep the new edition sooner or later.

*PS: It seems like he is now focusing more on physic parts than graphics or engine parts.
