  1. I'm not an expert, but my reading from these videos is you do that in R*. You don't need an R** to understand K + 1/K.

  2. It's observation, not governance.

  7. Someone else who answers another copy of this comment says it depends.

  11. No.

  12. R^2 doesn't have order.

  13. Omega comes from ordinals.

  14. But category theory is usually defined based on ZFC.
