--I listened to this Nima Arkani-Hamed lecture, my computer was able to handle it although took an hour to download. One thing N.A-H mentioned as a key building block was that it is impossible for a particle to have spin>2. However, in "string theory" just spin a string harder. You can get whatever spin you want, no matter how large. No? So: How are these two claims to be reconciled? [I have asked this question of physicists before, by the way. So far, I have never got any answer back I considered reasonable.]
