For the last few months I've been watching and enjoying a lot of educational YouTube videos produced by the Australian independent film-maker and video journalist, Brady Haran. These are short videos about computers, mathematics, physics, chemistry, language, philosophy, and other topics.
It appears Brady has moved to the University of Nottingham in the UK, and many of his videos are produced with the assistance of faculty from that institution.
Perhaps many of the regular visitors and contributors to DonationCoder are familiar with these videos, but I don't see any references to them in the forums and thought they might be of interest.
