Why 1 + 2 + 3 + ... equals -1/12
Original: 1 + 2 + 3 + … = -1/12 Seems Impossible. It's Not. And it's Very Important In Physics.
A widely discussed explanation of the counterintuitive result that the sum of all positive integers equals -1/12 is drawing large attention. Mathematicians and physicists point out that the series diverges in the usual sense, but the value -1/12 emerges through analytic continuation and regularization methods such as the Riemann zeta function. The result matters in physics, appearing in string theory and in calculations of the Casimir effect, which is why the surprising claim keeps resurfacing.
Why now: The counterintuitive mathematical result and its real role in physics puzzles and fascinates audiences.
