along similar lines, playing with http://xaonon.dyndns.org/hawking/hrcalc.js I came unto a surprise: fill in the estimated mass 3.4 10^54 kg of the the known (?) universe into the formula for a black hole, and estimate the diameter (or circumference/Pi for you singularophobics out there), what diameter do you get? to be (inside) or not to be (inside), that's the question Wouter. -----Original Message----- From: Warren Smith Sent: Wednesday, January 16, 2013 2:39 AM To: math-fun Subject: [math-fun] Best explanation of the Higgs particle
Here's the download link for the full-motion video: http://online.itp.ucsb.edu/download/bblunch/arkanihamed2/snd/Arkanihamed2_Bl...
--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.] _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
