I found this site recently and a quick search did not turn up thread on it:

I found this a few days ago. I've been watching a few of the videos from the biological courses.

The site has great potential (:

This site looks awesome! Thanks for sharing it. As soon as I have a little free time I plan on making use of it.

I listened to about half of the single astronomy course, which is Yale's Astronomy for non-scientists. It is very good; while I know most of the main points about the three big questions he is looking into in the course (planet detection, black holes and dark energy) he fills in a lot of practical stuff I didn't know. He explained that while using the Doppler method of detecting planets one star showed a 2% dip in the brightness at the suspected period, and that first detected transit nailed down the existence of the theorized but unproven "hot Jupiters" (Jupiter-sized planets orbiting at 1/8 the radius of Mercury's orbit, with periods in days). They used eight days of SST time to attempt to find transits in a star cluster and found zero, rather than the roughly 30 they expected to find. Monday morning quarterbacking detemined why, and they tried another seven days spent in looking at a star-dense place in Sagittarius, and this time found sixteen transiting planets.

Neat stuff, makes me want to become a student again.

It's a neat site, but doesn't appear to be updated with new lectures regularly. I hope they change this because it has a lot of potential.

I'm sure this link has been posted elsewhere, but I thought it might be nice to put it in this thread as well:
