I just returned from the 39th German Autumn School for High Energy Physics Maria Laach.
Maria Laach is a monastery in western Germany located in the caldera of an old vulcano.
Covering lectures from cool to reasonable good, from detetor physics to extra dimensions as well as exercises on Feynman diagrams and group talks.
For physicists: One of the guys doing all that elektroweak radiative-corrections stuff I used in my master thesis (Uli Baur) was there and also one of the heads in extra dimension theories (Nima Arkani-Hamed)… both with cool lectures!
