Notes on the Proof of Pi

This is where the great mathematician, Albert Einstein, scribbled down his thoughts on the infinite digits of Pi.

Or, as he put it, "I've found a way to calculate the value of Pi, now if only I could find a way to calculate a good haircut..."

The notes contain some of the most famous equations in history, including:

• Equation 1: 3.14159265359 = 22/7
• Equation 2: 3.14159265359 ≈ 3.14 (for the layman)
• Equation 3: 3.14159265359 × 10^100 = 314159.2653589795... (for the truly adventurous)
