Randall Munroe writes xkcd, one of the very few webcomics that I can truly laugh at, connect to, and that I never get tired of. (I love dangling prepositions!) He’s a very smart and insightful guy, and often interjects math and science into the strips, as well as purely philosophical ramblings. He gave a talk at MIT a few weeks ago.

Here is a link to some pictures from the talk.

And here are some videos of the event, including him being pelted with plastic balls (which is homage to one of his strips about the nature of becoming an adult.)

and you can find a few more by using this xkcd query to YouTube.
