FRS 106, Michael Littman – Spring 2019

Week 7: Tuesday

First day back from Spring Break!

  • Discussion Part 3 (Rayyan)
    • They climb mountain; Chris has resentment towards his father
    • Gets spooked because he hears rockslides, feels like something bad will happen so they decide to climb other peak next time
    • Quality is the dao. Phaedrus started reading the dao, and it is exactly what he was trying to explain in quality.
    • Poncaire: chaos theory, getting away from absolutes
    • End of absolutes (beginning of 20th century), no more absolutes (time, space, substance, magnitude, etc.) is relativity (time dilation, length contraction, antimatter, quantum mechanics)
    • Go back to Bozeman for a night for rest
    • Different font so Phaedrus is re-taking over the mind and this worries the narrator
    • Heads for California
    • Quality is something inherent in every single philosophy and this was not considered before, like the Buddha
    • 3 diff ways of getting stuck: gumption traps (like grit that helps you persevere thru challenges, can rise and fall) (parts failure, intermittent failure), setbacks (ego traps, value trap, etc), hang-ups
    • Monkey trap: monkey puts hand thru hole to grab rice but then gets stuck
    • Dream with the glass door: he has a dream where he’s behind the glass door and wife and Chris are on the other side, Chris trying to ask him to open door but he wont
    • Miu: everything can be answered by yes/no question (Japanese concept)
    • Miu if you cant answer w yes or no, then you answer miu because you need to ask a better question
    • Most important part is the traps!! Learn to just stick with it
    • If things not going well, chill
    • Most mistakes happen when you’re working on something too long
  • Discussion Part 4 (Leslie)
    • Opens w the dream again but more specific and figure in shadows doesn’t let him open the door, wakes up and sees he’s strangling Chris, dreamer is Phaedrus
    • Phaedrus gaining more control
    • Wants to hospitalize himself
    • More flashbacks about endpart of phaedrus’ journey before insanity
    • Phaedrus interested in Greek philosophers, had a fight w the director of the program at UChicago
    • Logically concluded that he was approaching insanity
    • Dualism: Phaedrus used rhetoric, Director used logic
    • Reference about art and quality
    • Quality is goal of art
    • Realizes Chris misses Phaedrus
    • Chris Thinks narrator is different
    • Narrator sees mentally problematic habits in Chris
    • Phaedrus takes over in last conversation w Chris
      • Nice resolution
      • Chris asks, “are you insane?”
      • Rid binaries and united these 2 things
      • Told Chris he’s similar to Phaedrus
      • Weary at first but Phaedrus does things not really sane but realizes that Phaedrus isnt really insane
      • Chris trying to impress father, push world away
      • Better that Chris found a sol’n before finding out the way Phaedrus found out
  • General comments and reviews about the book:
    • Owen: not what i expected it to be, thought it would be about getting down to basics and slowness, but actually was about a guy who was insane
    • Jack: story was very good, bogged down a bit because philosophy is heavy
    • Sarah: interesting take from motorcycle perspective
    • Prof: very good
  • Shop Class as Soulcraft
    • Value of labor
    • A bit preachy
    • What one gets out of working on a motorcycle
    • When one is being diagnostic, you ask, “what does it need”
    • Asking questions is a higher level of intellectual activity than just providing answers
  • Talking about the Clutch of our motorcycle
    • Bolt and nut loose which is why didn’t work before
    • If you release, everything slips so you don’t hurt yourself nor motorcycle
    • When slips, bottom chain tight and top chain loose
    • 100 pounds in bottom chain
    • 10 pounds, 1 foot
    • coeff of friction rubber, asphalt = 1
    • coeff of friction steel, steel = 0.2
    • 200 foot-pounds to move a bike, exerting more wont really help you
    • 20:1 gear ratio, so you only need 10 foot-pounds on smaller sprocket
    • To slip at higher torque, either stiffer spring or more friction plates
    • If you stiffen springs, handle stiffer so harder to operate too
    • Slips at lower torque: easier to use clutch release, easier to kickstart, but you don’t want it to release when you need power, but you wanna make sure it does release at a certain torque
    • This shows braking of the engine
    • Clutch helps you disconnect gear from motor so you can shift gears
