The Age of Science: 1600 - 2000


This is the Age that has led up to the present. It begins around 1600, in which year Kepler went to work for Tycho Brahe and was able to use his observational data to eventually deduce three laws of planetary motion, Gilbert wrote on magnetism, Bacon on scientific method, Galileo and Marius began telescopic observation, discovering the satellites of Jupiter, and the church executed Bruno for heresies arising from his musings on the consequences of the Copernican system. Greater detail will be found in the pages on individual sciences. This age includes the development of the mechanics of Newton, and its later half sees the steam power of the industrial revolution, and the evolutionary revolution in biology of Darwin and Wallace.

On July 14, 1933 the Nazi Cabinet in Germany passed the Law for the Prevention of Hereditary Diseases in Future Generations. This law, which was to be implemented on January 1, 1934 called for the sterilization of "lives unworthy of life". These "unworthy lives" included those persons suffering from congenital mental retardation, schizophrenia, manic-dpressive insanity, epilepsy, Huntington's chorea, hereditary blindness, hereditary deafness, grave bodily malformation, and severe alcoholism. To enforce the sterilization laws, Nazi leadership created special "Hereditary Health Courts." All physicians were legally required to report to the courts anyone they encountered who fell into any of the categories for sterilization. As a result, by 1937 some 225,000 individuals had been sterilized by German authorities, a figure that was roughly ten times the number in the United States.
