Euler’s proof that the sum of all positive rational integers is -1/12 |
Euler discovered the zeta function. In a remarkable paper written in 1749, Euler calculates several values of the zeta function in regions where the series definition of the zeta function does not converge. We discuss Euler's proofs and relations to a solar eclipse on July 25, 1748 which Euler also wrote about.
