So, at the risk of never getting invited to give another talk, here’s the video of the colloquium presentation. (Due to technical difficulties, the video starts about 2 minutes into the talk, but the bulk of the presentation is here.) The talk itself is about 45 minutes long, with the remaining portion devoted to questions and comments from the audience.
If you’re interested in inviting me to speak on science communication, or on a number of scientific topics such as black holes, dark matter, or the like, please let me know. My speaking portfolio lists some of my past presentations; I’d be happy to share more information about any of those.
