Quantum zeta epiphany: Physicist finds a new approach to a $1 million mathematical enigma

Numbers like π, e and φ often turn up in unexpected places in science and mathematics. Pascal's triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there's the Riemann zeta function, a ...
