Why this trick should be IMPOSSIBLE ft. Rodney Mullen - Skateboarding Science

Hi Diana, I love your shows. I majored in physics and math, got my BA, went to work at Grumman Aerospace just 2 weeks after Graduating,  started working on the A-6A, the Navy's  bomber Weapons systems.  Sure used my General Physics on that job.  Did bombing runs at Patuxent River Test Range in MD.  God it was fun seeing gravity at work. Got to fly a helicopter 3 times as part of that job too . Even more fun. You'd like it, and it's harder than flying a plane by LOTs, to do it well. Physics is the best degree to get . I also got to see the Collidors at Brookhaven Lab on Long Island, and the one in Chicago as well.  More fun. You're one of the few girls I'd like to have worked with. I led (managed) a neat group of 30 Systems Engineers (25 M/5 F) later in my career,  Made group leaaders out of three of them, women, cause they were really smart.  I always tried to hire people smarter than me 'cause it made my leadership job soooo Much easier. 
Thanks for showing and solving the sliding rocks problem, I was there and it was always dry at the time.  I would have believed gophers moved them at night just to bug us humans.  Good job, AS Usual. You are a unique young lady. Congrats.
