P vs NP is the biggest open question in computer science, and it fits on a shirt: some problems are brutally hard to solve but trivially easy to check. Finding the path through the maze takes ages; confirming a path works takes a glance. There's a million-dollar prize for settling whether those are secretly the same difficulty, and after decades, nobody's collected. What gets me is how much of life runs on the same asymmetry — years to write the book, a weekend to read it. Hard to solve, easy to verify. Ask anyone who's finished anything.

Printed on the Bella + Canvas 3001 — soft, lightweight airlume cotton with a retail unisex fit.
