I highly recommend this talk. It inspired me to get the book, which unfortunately came in audiobook format and not read by the author. After seeing the talk it was kind of hard to sync the voice with the real scientist. Still, the content was awesome. Randall covers the topic in great depth, including a lot of context regarding the history of scientific discovery and understanding of meteor impacts, a subject I regret not making the focus of my career. What a dumbshit I was in college! The theory is surprisingly straightforward (and amazingly cool) but it’s much better to hear it from Lisa so watch the talk.
