comment An algorithmic approach to constructing the real numbers
@AsafKaragila If somebody proved that the numbers produced by my (sketched) construction are exactly the computable reals, I would certainly accept that answer.

comment Which hot math research fields became insignificant later on?
Quaternions in the nineteenth century, and traditional algebra in the sense of the concrete computation of roots of polynomials.

comment Find the group of automorphisms of the Petersen graph
Standard drawings of the Petersen graph are highly symmetric. Use your visual intuition to list all the automorphisms (and then use your logical mind to make sure that's all of them).

comment How to prove if log is rational/irrational
Could you pin down a more specific question? "Advice on approaching thought construct to logs" is very broad and vague.

This is exactly the same as the standard Knight/Knave puzzle involving two doors. The proposition "the left door is the correct one" is replaced by "someone has proven GC", that's all.

comment Hashing With Chaining Collision
Could you be a little more detailed about how the hashing works? The objects are numbers $1...1000$, the keys are numbers $0...9$, but what does "two keys map two elements to one index" mean?

Do you really mean a point in the disk, or in the circle?
