Hurwitz Memes

Ever notice how mathematicians get excited about the weirdest restrictions? Hurwitz's theorem is basically saying "Hey, cross products only work in 3D and 7D spaces, deal with it." The rest of us are left wondering why anyone would care, while math folks are having existential crises over vector operations. It's like finding out coffee only exists on Mondays and Thursdays—completely arbitrary and yet somehow profound. Next time someone tries to calculate a cross product in 4D space, just hand them a tissue for their inevitable tears.
