1953, biologists Watson and Crick discovered the double helix structure model of ——DNA, the genetic material of life inheritance;

1954, the world's first nuclear-powered submarine Nautilus, designed and manufactured by the United States, made its maiden voyage, announcing the arrival of the nuclear submarine era;

From 65438 to 0954, American biologists invented the world's first effective oral contraceptive and conducted the first batch of clinical trials.

1958, Americans discovered the laser. Two years later, 1960, the first ruby laser was born.

1959, American engineers made the world's first industrial robot;

On April 1960, the United States launched the world's first experimental meteorological satellite;

/kloc-the toilet invented in the 0/6th century became popular in this century;

1962, American physicists put forward the quark model for the first time and predicted that this extraordinary particle not only exists, but also constitutes all other particles.

1964, IBM of the United States successfully developed the world's first universal integrated circuit.

1964, American Bell Company introduced videophone;

1968, American and French scientists put forward the plate tectonics theory;

In August 1968, 1 1, a scientific research ship named "Gegema Challenger" started its maiden voyage with the goal of deep-sea drilling. After a voyage of 15 years, not only the theory of continental drift and plate tectonics has been verified, but also many important scientific discoveries have been made.

1968, Stanford research institute developed the world's first intelligent robot.

1969, the Pentagon started the Internet.

1in July, 969, the Apollo spacecraft was launched. 2 1, 1 1: 56, astronaut Armstrong set foot on the moon.

His small step marks a big step for mankind;

197 1 year, the world's first general microprocessor came out, known as the first generation microprocessor, and the first microcomputer was born;

1973, the world's first optical fiber communication experimental system was built in Bell Laboratories, which laid the foundation stone for the information superhighway.

1975, American william miller made the world's first small electronic game machine;

From 65438 to 0976, the United States began to use the first generation of cordless telephone systems, and mobile phones gradually became modern "windward ears";

1977, the United States announced that it had developed a neutron bomb and began to put into production its armed forces;

1981April 12, the United States spent 10 billion dollars to launch the space shuttle "Columbia" into the sky for the first time, making it a spacecraft that can freely shuttle between heaven and earth;

1983, the United States successfully developed digital TV;

1984, Apple introduced the world's first multimedia computer.

1990, the implementation of the human genome project marked the first page of the human "book of life";

199 1 year, the World Wide Web (WWW) based on the Internet officially appeared. This invisible network makes it very convenient for people to transmit information to each other, just like shuttling through the network.

1993, eight scientists who lived in the isolated "Biosphere 2" for two years walked out of this artificial small world safely, marking the end of the first experiment of the American "Biosphere 2" program;

From 65438 to 0993, the United States included the information superhighway in the government construction plan, and for a time, the information superhighway became the most interesting topic in the world.

1In June, 1995, the American space shuttle Atlantis successfully docked with the Russian Mir space station, which indicated that international cooperation among human beings in space activities was becoming a trend.

1997, the American Pathfinder Mars exploration spacecraft successfully landed on Mars. Scientists believe that it will no longer be a dream for humans to land on Mars one day.

In May 1997, 1 1, IBM supercomputer Deep Blue defeated the chess master Kasparov with 2 wins, 3 draws 1 negative. This man-machine war has caused different repercussions in the world.

1On June 3, 998, at 6: 06 a.m. Beijing time, the first high-energy physics experiment "Alpha Magnetic Spectrometer" to explore the origin of the universe was successfully launched with the American space shuttle Discovery. For the first time in thousands of years, human beings have directly observed charged particles in space.
