//Pd. 7 Schafer quantum. The Heisenberg Uncertainty Principle was covered during the previous class. //Mike leaves the room right before pd. 7 starts to look for his backpack. Schafer doesn't realize this. //1 minute into class: Schafer: Wait, where's Mike? Eric: He went to look for his backpack. //Mike comes back without a backpack. Schafer: Where'd you go? Mike: I went to look for my backpack and I still don't know where it is. Naeem: Wait, isn't it right there? [Points to backpack.] Mike: Oh yeah, thanks. Student: That's like Brownian motion. Schafer: How is it like Brownian motion? Mike: Wait, no. It's like the Heisenberg Uncertainty Principle. I knew _exactly_ what its momentum was, so I didn't know where it was. Schafer: Yeah, true. He knew _exactly_ how fast it was going, so he couldn't have had any idea where it was. //A few minutes later, Schafer calls on Mike to explain something. The tables in the classroom are unusually arranged, so Mike can't get to the front of the room. Schafer: Yep, I set up these tables like that _just_ so you couldn't get to the front of the room. //Mike succeeds in getting to the front of the room. Mike: Oh yeah? Well I just thwarted your plans! //Schafer throws Mike a marker, but throws it badly intentionally, that way Mike can't catch it. Mike doesn't come close to catching it. Schafer: Ha! What now‽ Mike: To be fair, I knew exactly how fast the marker was travelling.
