Take a knot k, and call it a number.
To that point, does anyone know if there is a formal definition of what it means to be a number? I know we have number systems in which the Integer-like numbers do not behave the same as the Integers, where the numbers of that system are defined completely independently of the Reals.
- ds9 13y agoOh yes, some outstanding thinkers have gone into mind boggling depth on the meanings of fundamental maths concepts. This started getting a proper treatment in the early 20c. (see https://en.wikipedia.org/wiki/Principia_Mathematica https://en.wikipedia.org/wiki/Principia_Mathematica ) and presumably has come a long way since then. Edit: Of course one has to take a different approach for pedagogical purposes.
