Nothing says "I've made terrible life choices" quite like staring at a Moody diagram for three hours straight. The logarithmic scales, the overlapping friction factor lines, the tiny numbers that require electron microscopy to read... Engineering students develop a special kind of eye strain that ophthalmologists can identify on sight. "Ah, fluid mechanics trauma. Take two aspirin and never look at Reynolds numbers again." For the uninitiated, a Moody diagram helps engineers calculate friction in pipe flow, which sounds straightforward until you're squinting at intersection points between curves that might as well be quantum superpositions. The Hulk's confusion is the perfect embodiment of every student who thought engineering would be about building cool stuff rather than developing migraines from indecipherable charts.
