osmosis
In biological and chemical contexts, this term describes a precise physical mechanism of equilibrium. It evokes a sense of passive, automatic movement driven by concentration gradients, where nature seeks to balance a disparity between two environments. When used figuratively, the word shifts from a physical process to a cognitive one. It describes a form of learning that is effortless and invisible, occurring not through formal study but through immersion. This usage implies that knowledge is absorbed like a fluid, seeping into the mind simply by being in a specific environment.
