Something I’ve worked hard on is the Carnegie Astronomy Lecture Series. This is a very popular series of talks given primarily by Carnegie Astronomers on all sorts of astronomical topics. They are usually given at the Huntington Library and Botanical Gardens and recently have been so full that people have been turned away.
The Huntington makes audio recordings and publishes when in iTunes U, but that doesn’t really work well in astronomy, which is highly visual. So that’s when I decided to try and pair the Keynote/PowerPoint slides with the audio. There here’s the result.
