Why circles dont exist

For a circle to be perfect, we would need to measure an infinite number of points around the circle's circumference to know for sure. Each point would need to be precise from the particle level to the molecular level, whether the circle is stationary or in motion, which makes determining perfection a tricky feat. Much like Schrodinger's cat's suspended existence, the answer is not clear cut — there are all kinds of possibilities.

In this vein, maybe a circle in nature is perfect, maybe it isn't, but our ways of knowing are limited by the constraints of our physical senses. What we do know is that perfect circles abound in mathematics where lines and points are safe from the finite restrictions and forces of the material world. Man-made circles — that may or may not be perfect — abound around CMU's Pittsburgh campus.
