...travels 8,000 miles a week, lashing out at abortion, pornography and homosexuality. He has been to Harvard to duel with jeering students who spilled over into three auditoriums to hear him, and to Oxford to debate Prime Minister David Lange of New Zealand about nuclear weapons. He dares Scientist Carl Sagan to debate creationism; Sagan has declined the challenge. He has a private session with South Africa's President P.W. Botha and sides publicly with his white government...
...technique behind all these systems can be traced to MYCIN, a computer program written in the mid-1970s by a Stanford physician and computer scientist named Edward Shortliffe. Using tools developed for AI research, Shortliffe boiled down everything he knew about diagnosing infectious blood diseases and meningitis into about 500 "if-then"rules. Rule 27, for example, said that if an organism found in a patient's blood is rod shaped, gram- negative and able to survive in the absence of oxygen, then there is a strong likelihood that the organism is a type of bacteria called Bacteroides.

Fox), a pleasant 1985-style teenager, exclaims to his shock and chagrin, "My mom has the hots for me!" This takes some explaining. Marty's pal, an aged, eccentric scientist (Christopher Lloyd), has fashioned a De Lorean car into a functioning time machine. Suddenly, Marty finds himself in 1955, in the bedroom of the 17-year-old girl (Lea Thompson) who will be his mother, if -- big if -- he can deflect her crush on him toward the nice-guy nerd...
