Hello Dr.Lewin, I have watched your physics lectures online and just wanted to thank you for teaching them with passion and love unlike some of my professors. Stupid question here: how long did it take you to master drawing a dotted line with chalk the way you do? Thanks!

I estimate its a 5:5

Did you ever watch Barney on tv or were you only on the show and not really a fan?

What did you use as motivation to get you hyped up before a fight?

What do you like doing in your free time other than magic of course?
