Richard Feynman on the electromagnetic spectrum. "But you gotta stop and think about it ... to really get the pleasure about the complexity; the inconceivable nature of nature" http://en.wikipedia.org/wiki/Electromagnetic_radiation a second or third gen PAL VHS dub of a vintage original off-air NTSC VHS tape, then captured and compressed and found on a torrent site. squashed, re-compressed and converted for YouTube. all sorts of obvious video and audio problems, but at least it's here, a special treat from the past. anyone with better source, please drop a comment. in the meantime, point your 1/8" black-holes at this nice piece of tape of The Chief.
