// Talking about fluids Schwartz: Every vehicle is a submersible! Schwartz: Your bike is a submarine!
Schwartz: So here we have a tank of some liquid. Class: Hydrochloric acid! Schwartz: What? Oh, this is a different kind of tank problem. We're trying to drain the tank here. Hadar: But what about the magical Stevens and Isaiahs? Schwartz: Oh. They'll be drained out too.
// Schwartz monologue I am technically qualified to teach Physics, by the way. You can get qualified to teach a subject by just taking a test. So I went to Schafer and asked "what's on the physics [qualifier] test?" He says "you took AP Physics in high school, right? And you majored in physics in college?" "Yeah." "Then just review what you learned in high school. You'll be fine." Now, in high school, I took AP Physics in 11th grade. And in 12th grade, I took another physics course that went into much more advanced stuff based on multivariable calculus. None of the test was what I studied, and none of what I studied was on the test. I study for the test; I'm about to open the test; I'm ready; I know how to apply Stoke's theorem to these things ... and I open the packet, and the first question is "what is entropy?" I don't know this. Entropy is something to do with heat, right?
Schwartz: Nothing about this was clear, but do you have any questions?
// about slinkies Lodal: Last time, when we borrowed one from Physics, we damaged it. And I was told not to borrow it again. Lodal: It was probably my fault, but I'm gonna blame someone else.
// Pd. 6 Freshman Physics. After a conversation about sonic booms, the class is in a conversation about how sound cannot travel in space. Ari: Yeah, just saying, silent explosions would be SO MUCH COOLER than loud explosions. George: Did you mean, the type of explosion where you tie two masses together with a piece of string and cut the string? // (See #9641) Ari: No, I mean, blowing stuff up. Like "boom" explosions. Like arson.
// Pd. 6 Freshman Physics. Schafer is discussing the Doppler effect. Schafer: So let's say Ayush sees a fire truck and he runs towards it screaming fIRE TRUUuUuUuUuUuUCK! Schafer: Yeah, just like that. Michael: ...Am I the fire truck? Ayush: Then I would run away from you.
// Pd. 6 Freshman Physics, Schafer is talking about “bouncy” (elastic) and “sticky” (inelastic) collisions Schafer: Really every collision is some amount inelastic, so it’s not perfectly bouncy or sticky. Schafer: If you’re playing football and you run into someone there’s a sort of bounciness effect. Ari: people are bouncy! Schafer: ~some~ people
// Pd. 6 Freshman Physics Schafer: Now I’m going to demonstrate an explosion. It’s not very loud or exciting. But still, this is probably the only explosion you’ve seen at school today, and the coolest part of your day.
// Pd. 6 Freshman Physics, Schafer is talking about momentum and impulse Schafer: If Michael is walking down the street and a horse kicks him, after giving the horse a carrot for being a good horse— Michael: wait how is it a good horse? Schafer: All horses are good.
