In the past 100 years, what areas of mankind have not progressed?

The top ten inventions of the 20th century are 1 and relativity 1905. Einstein, the greatest scientific genius in the 20th century, founded the special theory of relativity at the age of 26, which paved the way for the theoretical application of atomic energy. In 2005, Einstein founded the general theory of relativity. It profoundly reveals the internal relationship between time, space, matter and movement. So it has become one of the basic theories of modern physics.59980.999999998995 2. Quantum Mechanics 1900, Planck founded the quantum theory, and put forward a new concept that energy is not infinitely separable, and the change of energy is discontinuous. The establishment of quantum mechanics in the late 1920s was another revolutionary breakthrough in classical physics after the establishment of 1905 to 19 15. It successfully reveals the basic laws of the microscopic material world, accelerates the development of atomic physics and solid state physics, and lays a theoretical foundation for nuclear physics and particle physics. Therefore, quantum mechanics can be said to be the most productive scientific theory in the 20th century. Today, it still has strong vitality. Since 1930s, the basic structure of matter, gauge field, BIGBANG, double helix structure of genetic material molecules, tectonic plate theory, information theory, cybernetics, system theory and other theories have been created, which has further expanded human vision to more philosophical, macro and micro fields. It has become a great driving force for the progress of human civilization. 3.DNA molecular double helix model1953 On April 25th, 2003, the British magazine Nature published the results of the cooperative research by Watson, 25, and Crick, 37, which was later hailed as the greatest discovery of biology in the 20th century. It is also considered as a symbol of the birth of molecular biology. 4. The theory of continental plate tectonics 19 12 Wei Gena put forward the theory of continental drift. After more than half a century's development, Rebichon and others put forward the theory of global continental plate tectonics 1968, which built the world into six major plates and several small plates: Europe, Asia, America, Africa, Pacific Ocean, Australia and Antarctica. It has been verified by more and more science, especially the strong support of marine geology. The fission and fusion reaction between nuclear energy and nuclear technology nuclei will produce and release far more energy than mechanical energy and chemical energy. The peaceful use of nuclear energy provides mankind with a safe, clean and inexhaustible energy treasure house. 1968+0942, the United States built the world's first atomic reactor. After the 1960s, nuclear power plants entered the practical stage and developed into an important energy source, accounting for about 1/5 of the global total power generation. Nuclear technology is also widely used in agriculture, medical care, materials, archaeology and environmental protection. 6 Aerospace and Space Technology 65,438+0903-65,438+0,965,438+04, tsiolkovsky put forward the rocket-powered navigation theory. It laid the foundation of astronautics. 1926, Goddard successfully launched the world's first liquid fuel rocket. 1957, the Soviet union launched the world's first artificial earth satellite with the rocket device of intercontinental missiles, and the "space age" began. 1969, the American Apollo left the first human footprint on the moon. 197 1 year, the Soviet union built a space station, and human beings had an activity base in space for the first time. 198 1 year, the United States successfully launched the space shuttle, and since then, humans have been free to enter and leave space. Since the late 1950s, human beings have begun to explore the moon, planets in the solar system and distant interplanetary space. Up to now, more than 100 space probes have been launched. Information technology is the fastest developing technology field in the 20th century. It has had a great and far-reaching impact on human society, economy, politics and culture. In 2006, the invention of triode electron tube made long-distance radio communication possible. In 2008+0947, the birth of the first transistor provided an important foundation for the integration and digitization of electronic circuits. 1945, the electronic computer came out. With the appearance of large-scale integrated circuits, computers are developing towards the extremes of giant and miniaturization. Laser technology 19 17. Einstein put forward the concept of "stimulated radiation" in the process of studying optical radiation. It laid the theoretical foundation of laser. The laser was discovered in 1958. The first ruby laser in the world was made in America in 1960. 1977 the invention of atomic laser. Biotechnology gene recombination technology (also known as genetic engineering) is the forefront of modern biotechnology, which flourished in the second half of the 20th century. The recombination of DNA can make creative use of biological resources. Realize the will of human beings to transform biological genetic characteristics and produce the biological types that human beings need. Since 1980s, hundreds of transgenic plants and animals have been obtained, which is of great significance to agricultural development. The research and production of transgenic drugs will bring new gospel to human health. Besides genetic engineering, biotechnology (bioengineering) also includes cell engineering, enzyme engineering, fermentation engineering and protein engineering. The first test-tube baby Louis was born in 1988+0978. Enzyme washing powder and tender meat powder are all products of enzyme engineering; The modern fermentation industry started with the production of penicillin, and now it has used fermentation engineering to produce antibiotics on a large scale. As for the need to transform the genes of natural protein to produce new high-quality protein that does not exist in nature, more and more attention has been paid to it, and it is called the second generation genetic engineering. 10 the internet has created a brand-new way of working and living in the study, research, communication, trade and entertainment of hundreds of millions of netizens.

Aircraft: when people evaluate the contribution of aircraft to mankind, they often regard it as the most dazzling invention of the twentieth century. 1903, the Wright brothers, who were cyclists, built the first airplane with an engine in human history. 1930, British mechanical engineer Frank Whitter.
