Can't wait to see how long it takes to remove the article. Linker (talk) 17:05, 5 September 2018 (UTC)
Proposed ideas for Munroe's Law:
- Any seemingly simple idea will be difficult to prove; the simpler it seems, the harder the proof.
- Any proof which is discovered by a layperson will have been previously discovered by an expert (or an "expert") in the field.

I feel like Euclid beat Randall to the punch here, a couple millennia. 16:54, 5 September 2018 (UTC)

I don't see that Thales has proven Randall's theorem. Do not to be confused with Thales's theorem, that's about right angles. Maybe I'm blind or just dumb, but if so it has to be explained with more traceable background. I just believe that this diagonal is so trivial that even the ancient Greeks weren't engaged on a proof. --Dgbrt (talk) 21:38, 5 September 2018 (UTC)

  • From Wikipedia: Other quotes from Proclus list more of Thales' mathematical achievements: "They say that Thales was the first to demonstrate that the circle is bisected by the diameter, the cause of the bisection being the unimpeded passage of the straight line through the centre."

  • On the other hand not all historian believe Proclus. But van der Waerden does: [1]. Alexei Kopylov (talk) 05:49, 6 September 2018 (UTC)

Rolle's Theorem counterexample?

Isn't the TAN(x) function a counterexample to this? Starting at a given point, it rises to infinity, then returns from negative infinity to the same point without ever having a slope of zero. 06:58, 6 September 2018 (UTC)
