Today, I am thankful for osmosis.
On this and other unseasonably warm late spring evenings, I fully understand and appreciate the principle of osmosis.
At day's end, the stuffy, inside air retains the heat while the outside air grows cool and refreshing. Dinner's aromas linger within the structure despite the open windows while fresh breezes sweep the front and backyard gardens.
After sundown, I imagine the steady exchange of air across the back door threshold that separates the outdoors from the in - cool atoms in, hot ones out - until the ambient temperature achieves a tolerable, even pleasant level. Cool enough for sleeping, reading or watching television; warm enough to ensure that the newly-planted tomatoes and peppers will survive yet another night.
Etymology: New Latin, short for endosmosis
1. movement of a solvent through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane
2. a process of absorption or diffusion suggestive of the flow of osmotic action; especially : a usually effortless often unconscious assimilation (learned a number of languages by osmosis ~ Roger Kimball)
For this blessing, I am grateful.
