The eternal battle between theoretical perfection and practical chaos! Mathematicians are sweating bullets over proper calculus rules while physicists are just vibing with their approximations.
In math world, canceling derivatives is blasphemy—like putting pineapple on pizza. Meanwhile, physicists are gleefully simplifying equations with that "close enough" energy. The dB/dt equation? Just cross out what doesn't work and move on!
This is why engineers build bridges with a 4x safety factor. They know a physicist was involved somewhere in the calculations!
