This clever design walks through the classic proof that the square root of two is irrational (it cannot be expressed as a ratio of integers).
We assume that root two can be written as a simple fraction, p/q. But as the proof unfolds, we discover that both p and q must be even, resulting in a fraction that can always be simplified further. This logical contradiction proves once and for all that root two cannot be expressed as a ratio of integers.
The last line features other famous irrational numbers: pi, phi, and e.
