The expectation vs. reality of physics in one perfect image! Up top we have the romanticized version: stylish people with neat beards and glasses, the famous E=mc² equation (which everyone knows but few understand), and pretty cosmic galaxies. Pure aesthetic physics! Meanwhile, the bottom half shows the gritty truth: sleep-deprived students hunched over at 2AM, surrounded by quantum field equations that would make Einstein sweat, vacuum fluctuation graphs that look like someone's having a seizure, and the Wheeler-DeWitt equation that basically says "good luck understanding the universe, buddy!" The transition from "I love physics!" to "I'm being physically and mentally destroyed by physics" happens faster than particle decay in a hadron collider. The floor-sitting position is the universal posture of a physicist who has abandoned all hope of normal sleep patterns.

When physicists get passionate about spacetime signatures. The Minkowski metric [+,-,-,-] versus [-,+,+,+] debate is the theoretical physics equivalent of tabs vs spaces. Some mathematicians would rather face eternal damnation than use the wrong convention. The signature determines whether time is positive and space is negative, or vice versa—a hill many physicists are prepared to die on. Next week: people who write Maxwell's equations without the constants.
