Re: [math-fun] Best explanation of the Higgs particle
Thanks, Robert. I must have had a transmission error while downloading the full-motion video. Yes, the full-motion video (".mov") plays fine with VLC. The version that _doesn't_ play video with VLC is the ".m4v" (if you click on "Download the Podcast") version, which is only 39 MBytes, and MediaInfo reports that this file has AVC-encoded video at a frame rate of .1 fps = 6 frames per minute. Many of the UCSB KITP podcast videos have this 6fpm format, which is fine for slides and (most) blackboard work. The VLC people don't seem to be interested in fixing this problem, which is a pity, because there are thousands/hundreds of thousands of "enhanced" podcasts available on the internet with very low or variable frame rate video. Windows Quicktime is the only player I've found capable of playing these types of videos correctly. At 12:31 PM 1/13/2013, Robert Munafo wrote:

I don't know if this file is corrupted or whether I had an error while downloading, but my downloaded video failed after about 60 minutes into this 80-minute video.
My version of VLC is version 1.1.10. (Intel 64-bit) for Mac, compiled by fpk with llvm-gcc 4.2.1 based on Apple build 5658, LLVM build 2335.6, and I'm running MacOS X 10.6.8 "Snow Leopard".
I was also able to use FFMPEG to recompress (transcode) the video into an M4V/MP4, which also plays in VLC with no troubles. This recompressed version is 752 MB (a little smaller than the original) and if you want I can try to upload it to Rapidshare or something.
Note that the VideoLAN "VLC" player will not play this video correctly; you have to use Apple Quicktime player (either Mac or Windows). Even iTunes won't play it correctly.
VLC will play the sound, but I found the pictures necessary to understand what was going on.

Good stuff. A very fun review of material that aging HEP guys like myself know, but need to to be reminded of every now and then. The discussion didn't cover the importance of renormalizability, but that might have been implicit if one dug deep. Sadly also missing, unless I am more out of touch than I think I am, is the possibility that the Higgs is itself a composite particle made up of more fundamental fermions. This is what I was hoping to hear about, but maybe it is a theory already obsolete due to new material developed after my time. (I worked on Technicolor theories with Howard Georgi when I was in grad school...) On Sun, Jan 13, 2013 at 1:21 PM, Henry Baker <hbaker1@pipeline.com> wrote:
