Mathematicians: locked in eternal warfare over the sanctity of calculus. One suggests a shortcut, the other has an existential crisis over "blatant approximations."
Meanwhile, physicists casually agree that a cow is a sphere because... why overcomplicate things? The spherical cow approximation is peak physics efficiency—strip away unnecessary details until your problem becomes solvable. Need milk production estimates? Spherical cow. Air resistance calculations? Spherical cow.
The brutal truth of science: mathematicians lose sleep over precision while physicists sleep soundly knowing everything is "close enough for practical purposes."
