While I was cramming for my for my physics test I was listening to one of my favorite scifi series Lensman by E.E. Smith, turns out It saved me at least 11 points on my last physics test, I tend to freak out a little when I'm actually doing a test and question facts that I damn well know, so this guy lets us have on side of a piece of paper for formulas, witch I like because in the real world I can pick up a book and look up say the moment of Inertia for some oddly shaped thing, well in my double guessing my self and having not expected it on this test I had completely forgotten that gravitational force is inversely proportional to the square of the distance, dumb luck I guess but I'm sitting there staring at the problem with my mind blank, and I start thinking about Lensmen then I remember the damn formula because it was in a conversation in the book. Woot yay for scifi.
