Hmmm tough choice. I doubt I would be able to understand DaVinci or Newton. I would prefer to berate Edison. I wouldn't want Curie to irradiate me. Tesla was awesome but kind of nutty. I didn't know Enough about Bohr. So probably Feyman or Einstein. I read Feyman's book so I think I would have a lot to talk about. But I think the win would go to Einstein for me. I just have to know how he came up with it all by just sort of thinking about it. I would hope he would have the best chance of explaining it in a way I could understand. Plus I speak German, so if all else fails we can just talk about spetzle.
