9、nd books.

Though she was put in jail for these activities, Sanger to publish and spread inf
10、ormation about birth control. She and her sister Ethel Byrne opened the first of several birth control clinics in America on October 16, 1916, in Brooklyn, New York. The Comstock Law was rewritten by Congress in 1936 to birth control information and devices. Many states had laws forbidding distribut

15、 Samuel Johnson said in a different era about ladies preaching, the surprising thing about computers is not that they think less well than a man, but that they think at all. The early electronic computer did not have much going for it except a marvelous memory and some good math skills. But today th
16、e best models can be wired up to learn by experience, follow an argument, ask proper questions and write poetry and music. They can also carry on somewhat puzzling conversations. Computers imitate life. As computers get more complete, the imitation gets better. Finally, the line between the original
17、 and the copy becomes unclear. In another 15 years or so, we will see the computer as a new form of life. The opinion seems ridiculous because, for one thing, computers lack the drives and emotions of living creatures. But drives can be programmed into the computers brain just as nature programmed t
18、hem into our human brains as a part of the equipment for survival. Computers match people in some roles, and when fast decisions are needed in a crisis, they often surpass them. Having evolved when the pace of life was slower, the human brain has an inherent defect that prevents it from absorbing se
