The eternal scientific showdown: enthusiasm vs. rigor! Poor William thought he'd revolutionized physics with his brilliant "Theory of Everything" until Professor Mustache demanded the mathematical proof.
This is basically every theoretical physicist's nightmare - that moment when your beautiful, universe-explaining epiphany crashes into the brick wall of "show your work." Without equations, your grand theory is just spicy science fiction!
The road to Stockholm is paved with differential equations, William! No mathematical proof = no Nobel Prize for you!
