A quick link to a place I stumbled across yesterday. iTunes U. It’s a collaboration that’s been around for a while between (American) universities and Apple iTunes. The universities post some of their lectures online, for all to view, in a sort of “open university”-style.
This allows for public access to lecture series in both video and audio, on general topics such as physics, chemistry and art. Besides that, there’s also a considerable library of free music from those universities. You may think of Mozart as sung by a choir, but also singer/songwriters.
Do check it out, if only for the music (some of which is rather good). This collaboration exemplifies the belief that knowledge should be shared, a similar goal as what I hope to achieve with this weblog.
