  • [[push]] [[eric weinstein explains gauge symmetry]]
  • [[eric weinstein]]
    • with [[joe rogan]]
    • [[gauge symmetry]]
    • "[[curvature]] in this context is the [[escherness]] of a [[system]]"
    • [[aharonov bohm effect]]]]
    • the "weirdness" in [[escherness]] is not actually weird in mathematical fields, and apparently also in [[physics]]: some physical objects seem to behave with escherness
    • the limits of linguistic thinking: there’s something about [[gauge theory]] that makes it so that it’s much easier/at all possible to understand via visual thinking
    • [[spinners]] are another thing that, when explained with words, just doesn’t make sense
      • [[philippine wine dance]]
      • [[joe rogan]] makes the right question at 18:20
    • [[klein gordon]] equation
      • [[paul dirac]] came up with a square equation that produced a spinner; one of the three most important equations in physics
