I love the 2-norm!Even in situations where

you would’ve thought only the 1-norm would

make sense!

So much for quantum mechanics. What’s the commonsense case for latke superiority?

LATKES ACTUALLY TASTE BETTER

Hot, fried, covered in sour cream or applesauce

Sort of OK

Edible???

Are you ready for an argument that’s probably never been made in the 60-year history of latke-hamentash debates?

Page 9: Superiority of the Latke: The Unexpected Convergence of Quantum Mechanics and Common Sense Scott Aaronson (EECS) SOUR CREAM APPLESAUCE.

Here—extremely unusually—quantum mechanics and common sense converge!

Lack of quantum 2-norm symmetry favored by God

Hard, dry, “classical” 1-norm corners

Bland, barely-edible hamentashen

Don’t trust authority! Taste for yourself!
