Give your baby the gift of knowledge with this mathematical proof onesie. The 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 dead-end 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.

Featuring a colorful "chalkboard" aesthetic with hand-drawn mathematical symbols, this design is as visually engaging for baby as it is intellectually stimulating for you.
