Found a cool site for Gravity stuff ( and others )

I've been tooling and surfing the net and found some seams of gold that I'd liked to share! :-)
#1 The Stanford Linear Accelerator Centre ( SLAC ) has a great sitefeaturing many streaming video lectures of their Summer Institutes ( SSI ), in particular this one which has some great lectures . I really dug the series by Sean Carroll - a general relativity primer - but there are some on interferometers including LISA, and also on 'gravity probe B' which is a polar orbiting satellite that tested near earth GR effects.
#2 Another site I found is at Fermilab streaming archives which has, obviously, mostly alot of particle physics but includes a fair slab of cosmology and astrophysics too. Thankfully they are rated according to the level of the viewer ( general public, student, physicist ) so you have a fair idea of what you're getting into. They're all quite viewable as far as I've seen but you can tune out of some of the more technical discussions and just grab the highlights if it gets too dense.
#3 You'd probably need broadband, but I can also recommend products at Applian Technologies called 'WM Recorder', 'RM Recorder', and 'WM VCR' which can capture those streams at any speed and save them for later replay as often as you like. That way you only have to download once, and you can schedule if you like ( as my ISP has a great deal on off-peak downloading ).
