the universe's lazy genius: everything spreads out simply because there's more room to be elsewhere.

means the process by which particles, ideas, or anything else spread from areas where they're crowded to areas where they're sparse, evening out until they're mixed throughout.

from From Latin diffundere, "to pour out" or "spread abroad" — built from dis- ("apart, in all directions") plus fundere ("to pour"). The same fundere gives us "fuse," "foundry," and "profuse," all sharing that image of liquid let loose. So the word literally pictures something poured out and going everywhere — which is exactly what diffusion does, whether it's perfume in a room or smoke in still air.

no engine
Driven purely by random molecular bumping, not force.
perfume math
Same equations govern heat, AI image models, ink.
slow giant
Pure diffusion would take years to mix coffee.
life depends
Your lungs swap oxygen by it constantly.
second law
It only ever runs toward greater disorder.
