// 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.

// Pd. 6 Freshman Physics Schafer: Everyone, say it: MMMomentum! So, what letter should we use to represent MMMomentum? Schafer: It’s P. Schafer: So from now on we’re going to call it pmomentum. // A few minutes later Schafer: Why is impulse written with a J? Now Michael said “jimpulse” would sound pretty ridiculous but “impulse” is from Latin. So is Spanish, and impulse in Spanish is “jimpulse” and if anybody here knows Spanish you know it’s pronounced [with the soft J]. Schafer: that’s actually all a lie but it’ll get you to remember it

// Pd. 6 Freshman Physics. Schafer is explaining an energy problem, and just drew a simplified dog. Michael (sarcastically): That is a GREAT dog! Schafer: Well, thank you, can you do any better? Michael: Just saying. That dog looks like one of Picasso's cats. Michael: ...That's not a compliment, by the way. Schafer: I know. If you were my ear, I would make like Van Gogh. Schafer: ...That's not a compliment, by the way.

// Pd. 6 Freshman Physics. Schafer is talking about scientific misconceptions, and just asked, "How high up is the Space Station?" Schafer: My guess is that, the less scientifically inclined the person is, the longer the distance they are going to guess. Tiancheng: I'm guessing 1 meter.

// Pd. 6 Freshman Physics. Schafer is introducing energy. Schafer: Now, I know that this might be a strange analogy, but we can think of the amount of energy in a system as the amount of pain it can cause. *Takes out bowling ball and approaches Michael*

// Pd. 6 Freshman Physics Schafer: Oh, Misha, I meant to ask you. What's 3 times 5? Misha: 3 times 5? Uh... 15. Schafer: 15? Okay, what's the number after 14? Misha: 15. Schafer: And the number before 16? Misha: ...15. Schafer: Oh good, because I was told you couldn't count to 15.
