There’s a reason the Pythagorean theorem keeps appearing in places it shouldn’t.

From coordinate geometry to signal processing…
from circles to spacetime…

It’s not just a formula about triangles.

It’s a description of something much deeper.

In this video:
• Why a² + b² = c² is really about areas, not lengths
• Proofs from Bhaskara, Euclid, and James Garfield
• How the equation defines distance in flat space
• Why it breaks on curved surfaces
• And how Einstein modified it to describe spacetime
