Related to second law of thermodynamics: entropy, Noetics

sec·ond law of ther·mo·dy·nam·ics

the entropy of the universe moves toward a maximum; similarly, the entropy of any isolated microcosm (for example, a chemical reaction) proceeds spontaneously only in that direction that yields an increase in entropy, entropy being maximal at equilibrium. To quote G.N. Lewis, "Every process that occurs spontaneously is capable of doing work; to reverse any such process requires the expenditure of work from the outside."

Entitled "The Two Cultures", it warned of the growing gulf between scientists and "literary intellectuals", a class he described as "natural Luddites" who not only sneered at science as an inferior branch of learning and were ignorant of the Second Law of Thermodynamics but in their complacent uninterest in the scientific revolution were blind to the menaces of nuclear weapons, overpopulation and the gap between the rich and poor.
