"Bob there's a goddamn rock headed our way."-Seth Shostak

This LPI is seven years old, or still current if I may paraphrase, and a rarity regardless. There is no slideshow and no slides to call attention to. Also the subject matter is quite light by LPI lecture standards.

Seth Shostak is of the SETI institute, and therefore much more of a theorist than experimentalist. This is good, when your subject is aliens. Astrobiology has yet to acquire a sample. 

As one would expect from a guy who doesn't bring slides, he does bring jokes, and they aren't terrible. He speaks about films with many citations, but hardly limits himself to any category more specific than 'all science-fiction.' 

At about 22:30 he starts talking about a time when he offered to proofread Star Trek scripts for Gene Roddenberry. He was rejected. And at around 29:00 I'm pretty sure he suggests circumstances where he would consider sexual assault. But by and large there aren't many timestamps to call attention to. He's mostly just amusing a crowd with light banter. The show goes into Q&A at 52:00.
