Caltech's Dr. Jose Andrade is the best man in the world to answer questions like: What happens during an earthquake? What location on Earth is most similar to Mars? How can you finally beat Angry Birds?

Dr. Andrade is an expert on granular materials. This guy knows more about sand than you even knew was possible. His work has allowed him to understand what makes particular earthquakes so destructive (why the ground is effectively turned into liquid) and also to extrapolate about what the surface of Mars might be like. 

Dr. Andrade advises the Mars Curiosity rover team and has played a role in many of the fascinating discoveries that the rover has made. Hear more about his work on the latest episode of You're the Expert, "Granular Materials".
