Unexpected Elements - Understanding the Anak Krakatau eruption
We have the latest from a year long investigation into the causes of the December 2018 Indonesian Tsunami. And we get a look at the first pictures from the Mayotte undersea volcano, which emerged earlier this year off the coast of East Africa.
As CrowdScience celebrates its third birthday, the team takes time to revisit some of our early episodes, and catch up with listeners to discover if the answers we uncovered changed the course of their lives? We hear from Zach, who has learned to let go of a possibly lost memory and Erin, who discovered technology could hold the key to finding the man of her dreams.

Lex Fridman Podcast - Sebastian Thrun: Flying Cars, Autonomous Vehicles, and Education
Sebastian Thrun is one of the greatest roboticists, computer scientists, and educators of our time. He led development of the autonomous vehicles at Stanford that won the 2005 DARPA Grand Challenge and placed second in the 2007 DARPA Urban Challenge. He then led the Google self-driving car program which launched the self-driving revolution. He taught the popular Stanford course on Artificial Intelligence in 2011 which was one of the first MOOCs. That experience led him to co-found Udacity, an online education platform. He is also the CEO of Kitty Hawk, a company working on building flying cars or more technically eVTOLS which stands for electric vertical take-off and landing aircraft.
