Exactly 150 years ago, Riemann published a short paper (in German) called
"On the Number of Primes Less Than a Given Magnitude." In it, he speculated
that the zeros of the zeta function all lie on a certain line called the critical
strip. This conjecture, now called the Riemann Hypothesis, is the greatest
unsolved problem in all of mathematics. In this talk we'll introduce the
Hypothesis and try to explain why mathematicians find this arcane-sounding
problem so compelling.
