Nice problem:

Let S be the set {(p,q,r) | p*x^2+q*x+r=0 has rational roots, p, q, r are prime}.  What primes appear in at least 7 elements of S?

This is kind of fun... a fake paper that purports to prove that the Euler-Mascheroni constant is rational. Enjoy.

This is actually a pretty amazing tool...
If anyone has ever tried to search for formulas or expressions through a traditional search engine they'll know that it is practically impossible to find anything you're looking for.
Symbolab is a search engine designed to search for these things.
I only just found this and haven't tried it out extensively, but so far it works pretty well.

This is hysterical...

Note: Most of these are better if you know US history, and some global history.
