… that I’ll mention this negative one twelfth business. From my string theory final exam this afternoon:
1. (g) What is the physical significance of the sum 1+2+3+…, and how can it be evaluated? What does it evaluate to?
I must have known it was coming somehow. Who ever said blogging isn’t good for my studies? I totally nailed that exam today. Where by “totally nailed” I mean “at least passed”, but that’s pretty good for this class.
I was worried I was going to sleep in today, or be really tired all afternoon, after having some trouble getting to sleep last night. I just lay in bed for at least a couple hours. Eventually my craving for a big glass of milk grew too great and I had to get out of bed. And of course once I was in the kitchen I had to have a cookie, and then make some tea as well.
Before long I was settled onto the couch watching i heart huckabees. There was a strange connection between that and my string theory studies, so I like to think the movie ended up putting things in a nice perspective and helped me pass. It’s all about the blanket. It’s all about space-filling D25-branes and their excitation modes. One and the same, oh baby yeah.
Sorry to resurrect that old topic, but you will be happy to know our happy tree friend is becoming nearer to reality.
