Nothing captures physics education quite like turning living creatures into geometric shapes for the sake of math. "Assume the cat is cubical" sits right alongside classics like "frictionless surfaces" and "spherical cows in a vacuum." Because apparently, real-world complexity is just too much hassle when you're trying to teach fundamental principles.
Next week: calculating the aerodynamics of a cat by assuming it's a perfect sphere with uniform density. The cat's angry face in the meme suggests it has strong opinions about being reduced to a simple cube. Can't blame it—I'd be upset too if someone ignored my non-Euclidean properties.
