Head to https://squarespace.com/drsean to save 10% off your first purchase of a website or domain using code DRSEAN What is the point of strange sums like 1+2+3+...=-1/12 or 1-1+1-1+...=1/2? These series diverge in the usual sense that we study in Calculus and use throughout most mathematics. But these alternative summation methods actually have physical meaning! Let's explore these weird sums and see why they are actually useful!
