About 90% of human knowledge has come during these last 50 years: development of electronics, calculators, and the Internet; the occupation of space. Consider this timeline: 1955 high-speed optical tracking developed. 1956 video recording machines use magnetic tape. 1959 maser patented. 1963 CODE V optical design software developed. 1965 compact disk patented. 1966 fiber optics proposed for long-distance communication. 1967 Hi Star surveys the cosmos. 1971 microprocessor born. 1981 the sale of personal computers approaches 300 million/year. 1990 the Internet has roughly a billion connections. 2000 Intel begins volume production of chips with sub-100-nm transistors. A new world has been built on the rapid flow of information made possible by this new technology.
