With the noble intention of self promotion, I am telling you about this talk, below, that I gave yesterday as a part of a series of physics graduate student seminars. I think the crowd was as nice enough as to actually ask me questions. I call this success! kind of. The most valuable part of this talk I think are the references (and the awesome Prague clock on the first page!) that’s why I am posting, since a fellow grad, Tristan, asked me to link it. Well, also, since I have talked about this topic that I have been reading about for so much I feel finally free to think about it differently: re-learn it if I am brave enough to  venture into re-learning.timetalk.pdfuntitled.jpg
