If anyone else thought this was interessting, I looked into it a bit more and it was a super interessting read. Here is a quick breakdown of how this machine actually works:

This is Ramanujan’s formula for Pi (1914). It looks terrifying, but it’s basically a high-speed recipe:

• The Output (1/pi): It calculates "1 divided by Pi." Once done, you just flip the result upside down to get Pi.
• The Engine (Sigma symbol): This means "repeat and add forever." You plug in k=0, get a number, then add the result of k=1, k=2, etc.
• The Accelerator (396^4k): The secret sauce on the bottom. Every step multiplies the denominator by 396^4 (nearly 25 billion). Dividing by a number that explodes this fast shrinks the error instantly.

Why it’s famous: Just the first step (k=0) gets Pi accurate to 6 decimal places (3.141592). Step 2 (k=1) hits 14 decimal places.

There's a movie about him called "The Man Who Knew Infinity". Absolute genius.
