Pi Is Exactly 3.14, Proof By Clock

This clock is what happens when mathematicians get bored with regular time-telling devices. Instead of boring old numbers, we've got mathematical expressions that would make your high school teacher either proud or have a nervous breakdown.

The highlight is the "3(π-14)" at what would normally be 3 o'clock. If π were exactly 3.14 (spoiler: it's not), then this would equal 3(3.14-14) = 3(-10.86) = -32.58. Which is... nowhere near 3. Nice try, clock designer!

This is the mathematical equivalent of those "live, laugh, love" decorations, except it's "calculate, miscalculate, give up and buy a digital watch." Engineers everywhere are quietly muttering "π=3" and walking away.
