Real world application Memes

The distance formula in action! Two wealthy guys playing ping pong becomes the perfect real-world application of that dusty coordinate geometry formula you thought you'd never use. The distance between (2,0,0) and (-3,0,0) is simply |2-(-3)| = 5 units... or in this case, exactly one ping pong table width. Who knew billionaires would be the ones proving that math actually has practical applications? Next time your students ask "when will we ever use this in real life?" just show them this image of wealth differential equations in their natural habitat.
