It's a collaborative project by various Australian Universities - and Australia has long been an exemplar of delivering education at a distance.
I've already done the Basic Physics course, which was excellent. And was given by a physics lecturer who owns a Bazinga t-shirt and isn't afraid to wear it.
I'm just getting to the end of the Chemistry course. That also is excellent; the lecturer occasionally likes to point out that there are no good chemistry jokes, and gives examples of very, very bad ones.
Both courses made my brain hurt at times - but in a good way.
Prompted by another thread, I went looking on youtube for one of my favourite scientists. That is Robert Sapolsky, and I already have a couple of his lecture courses on DVD. He specialises in biology and human behaviour. I found the first of his course of lectures given to students at Stanford University: https://www.youtube.com/watch?v=NNnIGh9g6fA.
