Wallis Memes

The mathematical evolution of π calculations is like watching someone go from "I'll just count the steps around this circle" to "hold my beer while I summon eldritch computational horrors." Starting with Leibniz's elegant alternating series, we progress through Wallis's product formula and Euler's beautiful square sum, only to arrive at Ramanujan's formula—which looks like what happens when you let a calculator have an existential crisis. Each mathematician basically said "Your formula is cute, but watch THIS." And then Ramanujan just decided to break mathematics entirely. That bottom equation doesn't calculate π—it summons π from whatever mathematical dimension it's hiding in.
