Why Does -1/12 Keep Appearing Everywhere In Physics?

PBS Space Time

Book a free consultation with an Odoo expert or start a 15-day free trial of Odoo: https://www.odoo.com/r/cAT Can adding every positive whole number really give you -1/12? We explore how physicists extract meaningful finite values from infinite sums, and how this strange mathematical technique shows up in the measurable Casimir effect and even helps explain why bosonic string theory requires 26 dimensions. .
