And Opposite Quantum Number Too

Engineering students having existential crises in Materials Science 101! The maddening paradox: metals (like steel) exhibit elastic behavior when they return to shape after stress, while "plastic" materials undergo plastic deformation (permanent changes). Meanwhile, the material called "plastic" isn't even technically displaying plastic behavior until it breaks! No wonder we're all screaming into our textbooks at 3AM. It's like calling a fish "wings" and a bird "gills"!

Opening a modern physics textbook for the first time is exactly like staring into the face of existential dread. One moment you're confidently studying classical mechanics, the next you're confronted with quantum superposition, wave-particle duality, and relativistic time dilation. The cat's expression perfectly captures that moment when you realize your understanding of reality was fundamentally incomplete. Schrödinger would appreciate the irony.

When your Shockley-Read-Hall recombination model suddenly transforms into an anime finishing move! Semiconductor physicists spend years studying electron-hole recombination at defect sites, and then some kid with white hair comes along and turns it into a purple energy blast. The phonon emission is just the universe's way of saying "physics has left the chat." Next time your professor talks about band gap theory, just yell "HOLLOW PURPLE!" and see if you get extra credit or detention.

Science enthusiast: "I believe only in science." Same person: *cries in failed exam scores* The cognitive dissonance of claiming scientific devotion while simultaneously struggling with the fundamental disciplines that comprise it. The duality of academic man. Pro tip: Believing in science doesn't automatically make science believe in you.

Physicists in the early nuclear age really said "safety equipment? Never heard of her!" Those hemispheres are literal plutonium cores used in nuclear weapons development, and scientists would handle them with basically zero protection. The "demon core" famously killed two physicists when they accidentally initiated brief criticality events by dropping a neutron reflector or using a screwdriver to prop one up. Just casually playing with potential nuclear chain reactions like they're appetizers at a fancy restaurant. "Yes, I'll have another serving of lethal radiation, please!"

Medieval knight: "We ride at first light." *Time-travels 4.6 billion years back* *POP!* The Sun literally forms. Knight arrives at the actual FIRST light in the universe and is like "Okay... where is everyone?" Talk about taking instructions too literally! Our poor knight just wanted to start an early morning campaign but ended up witnessing the birth of our solar system instead. Should've been more specific with those coordinates! Next time maybe try "we ride at dawn" instead of invoking cosmic timescales!
