1 x + y, Eugenia Cheng

  • def of "woman" is constructed, arbitrary
    • and they hurt! but mathematical thinking can help
  • mathematics is not just about numbers and equations, even tho it starts with them
    • at the heart of mathematics is the framework for making arguments
      • which had abstraction and logic
  • def abstraction: seeing past surface details in a situation to find it's core
    • hmm… i don;t agree with this. it's less about seeing "past" to find a core than it is about zooming out until the details are irrelevant, and seeing the patterns
    • does abstraction get to the core? ig it does in the sense that it distils..
  • two cultures of mathematics
    • problem solving
    • theory building
      • but what does this mean? ## theories
  • descriptive, not prescriptive
    • hmm… what about axioms?
  • works at higher levels of abstraction
  • the right abstraction hold great power in explanability
  • she is proposing one such abstraction / reframing, but for gender!

1.1 the problem

what is it? divisivness of arguments around gender equality.

  • society get's distracted by the argument of how men and women are different
    • this is a detraction! not the right argument
    • because it draws us into a meta-argument
      • this argument about what we should be arguing about only maintains the status quo
      • but, mathematics is v good at sorting this stuff out!

1.2 math time

  • mathematical deduction is not about averages on a large sample set
    • instead, they use logic, not evidence
      • reductionist? assumes our logic is good enough
  • individual experiences do not generalize to large groups
    • the reverse is also true
  • we can get around this with a case study, and then trying to generalize
  • yooo she does KBxSystemsofSystemsinNatureandDeepLearning#category theory
    • says that a similar type of seemingly small abstraction is possibly what she has now
  • not mathematics of gender, but a mathematical approach to gender
    • ie. a redefining
  • continual abstractions is the process of math
  • statisical link is not enough! math looks for causality
  • set theory asserts that math is fundementally about membership, whereas category theory asserts that it is fundementally about relasionships
  • she hopes to focus on relationships instead of intrinsic characteristics
  • abstractions can be temporary! you can details back in later

1.2.1 dimensions

  • because dimensions are by definiton indipendent, it's hard to define new ones
    • as you can't describe them w/ the existing dims
  • looking at too low of a dimensions messes things up
    • eg. a shadow instead of an object

lmao aight

1.3 inclass

abstractions can be applied cyclicy (ie. vec to matrix to tensor) "category theory is the science of metaphor" - ted
