The eternal academic rivalry captured in its purest form! Physicists looking down with pity on chemists while chemists respond with complete indifference is basically the scientific equivalent of siblings fighting in the backseat of a car.
This perfectly encapsulates the disciplinary superiority complex that runs through STEM fields. Physicists see themselves as dealing with fundamental laws of the universe while viewing chemistry as just "applied physics." Meanwhile, chemists are too busy making actual useful compounds to care about physicists' theoretical musings.
The real joke? Biologists are off-camera wondering why these two are fighting when they're both just creating problems that engineers will eventually have to solve.
