404 Memes

The universe has a way of keeping mathematicians humble! The Clay Mathematics Institute offers $1 million for solving each Millennium Problem, but even clicking on the webpage returns a 404 error. The irony is perfect—the mathematical formula on the error page (that summation with (5n+3)/2 for n=2) is teasing you with yet another unsolvable problem. Just like the Riemann Hypothesis or P vs NP, apparently finding the actual webpage is also an unsolved challenge! Maybe the real Millennium Prize is the existential crises we encounter along the way.
