||1986: Seventy-two Nobel Prize-winning scientists filed a legal brief with the U.S. Supreme Court challenging as unconstitutional a Louisiana law requiring schools that teach evolution to also teach “creation-science.” A news release described the scientists as “the largest group of Nobel laureates ever to support a single statement on any subject..” At a news conference in Washington D.C. the same day, they warned that the Louisiana law threatened scientific education by disparaging proven scientific facts to promote fundamentalist Christian beliefs.

||1990: B. F. Skinner dies ... psychologist whose pioneering work in experimental psychology promoted behaviorism, shaping behavior through positive and negative reinforcement and demonstrated operant conditioning. The “Skinner box” he used in experiments from 1930 remains famous. To investigate the learning processes of animals, he observed their behaviour in a simple box with a lever which, when activated by the animal, would give a reward (or punishment). The reward, such as pellets of food or water, acts as a primary reinforcer. He observed the behaviour of animals adapted to utilize the opportunity for a reward. He extended his theories to the behaviour of humans, as a form of social engineering. Pic.
