The Riemann Hypothesis
"officially" turns 150 years old this month(-ish).
One other notable 150th birthday being celebrated this month is Darwin's
On the Origin of Species
. Apparently, November 1859 was one helluva month.
It could mean that that point in time inherently contains some sort of cosmic
significance, almost as if it were the temporal junction point of the entire
spacetime continuum. On the other hand, it could just be an amazing coincidence.
