Something was invented in the 2o century

The major inventions and discoveries of mankind in the 20th century are: Marconi in Italy in 1901 invented radio communication, in 1903 the Wright brothers in the United States invented the airplane, in 1907 the Belgian B. Beckland invented plastic, in 1928 Fleming discovered penicillin in the United Kingdom, in 1923 Baird invented the television set in the United Kingdom, and in 1942 the United States nuclear ** was successfully developed.

In 1943, the British Turing computer, in 1953, the British scientist Crick and the American scientist Watson discovered the double helix structure of DNA, in 1957, the Soviet Union launched the first artificial satellite, in 1967, South African surgeons successfully performed organ transplant surgery, and in 1978, the first test-tube baby was born in the United Kingdom.

Invention is the process and result of applying the laws of nature to solve unique problems in the field of technology and proposing innovative solutions and measures. In order to meet the needs of people's daily life, the invention provides an unprecedented model of artificial natural objects, provides new processes and methods of processing and production, as well as machinery and equipment, instrumentation and various consumer products, and innovates and transforms manufacturing processes, production processes and detection and control methods.

1. Satellite TV.

The inventor of the television set was John Baird, an English electronics engineer, who in 1923 patented his invention of a device capable of producing an eight-line image. The first television set was sold at the end of 1930.

In 1932, the BBC aired the world's first canonical television program. Since then, mankind has begun to enter the age of television. Today, people use satellites and other means to transmit television signals to every corner of the earth.

2. Airplanes. Aircraft On December 17, 1903, the first powered aircraft began to fly. In 1933, the world's first regular air route was opened, which greatly expanded the space for human activities.

3. Nuclear**.

The atomic age began in 1942. In order to defeat the Axis fascists, the highest authorities of the United States decided to launch the "Manhattan Project" aimed at developing atomic **. At the end of the year, as part of the "Manhattan Project", the first nuclear reactor was built and began operation under a sports facility at the University of Chicago.

On July 16, 1945, a mushroom cloud rose from the Los Alamos Atomic Energy Research Center in New Mexico, USA, and the world's first atomic bomb** was successful. On August 6 and 9 of that year, the United States dropped two atomic bombs named "Fat Man" and "Little Boy" on Hiroshima and Nagasaki in Japan.

The Emperor of Japan then announced his unconditional surrender, and the atomic bomb seemed to have contributed to the victory in World War II, but mankind has lived in the shadow of the terrible atom ever since.

4. Computers.

In 1943, the computer, the computer was the foundation for human society to enter the information age, but it was born because of the war. In 1943, in order to decipher the German code, the British mathematician Alan Turing designed the first electromechanical computer called "Giant", although this was only an imaginary computer for decoding, but it created a precedent for the development of computer technology, and since then the development of computer technology has been changing with each passing day.

In 1947, the transistor computer was introduced; In 1959, the integrated circuit computer was born; In 1970, the large-scale integrated circuit computer was produced; Since the 80s, a new generation of microcomputers has emerged. On this basis, mankind has ushered in a new era of networking.

5. Contraceptive pills.

In 1954, American physician Gregory Pincas invented the contraceptive pill, which is a mixture of two hormones that inhibit a woman's ovulation.

The birth control pill is listed as one of the greatest scientific achievements of the twentieth century because it freed women from passive childbearing, from which women could control their own births, decide whether to have children according to their own wishes, and decide when to get pregnant according to their own circumstances.

There are many such discoveries and inventions, such as the invention of airplanes, tanks, computers, atomic bombs, penicillin, etc., as for the discoveries, the theory of relativity and quantum mechanics, the double helix structure of DNA, non-Euclidean geometry, etc., are innumerable.

The greatest invention of the twentieth century was the electronic computer (computer) and the application of Internet technology.

In the twentieth century, mankind invented automobiles, airplanes, computers, atomic bombs, artificial satellites, and cloned sheep.

1. Automobile: At the beginning of the 20th century, the American Ford invented the automobile, and the popularization of the automobile began.

2. Airplane: Invented by the Wright brothers, Americans. They made their first sustained powered flight in 1903.

3. Computer: The inventor is Johann von Neumann. Its field of application has expanded from the initial military scientific research to all fields of society.

4. Atomic bomb: Robert Oppenheimer, the leader of the Manhattan Project, led the creation of the world's first atomic bomb in 1945 and is known as the "father of the atomic bomb".

5. Artificial satellite: The first artificial satellite was successfully tested by the Soviet Union on October 4, 1957, followed by the successful trial of the American Explorer 1 on January 31, 1958.

6. Cloning sheep: In early 1997, British scientists successfully gave birth to a fatherless lamb, a pioneering feat that illustrates the imminent possibility of human beings to create life by methods other than natural means. Sheep cloning is an unprecedented leap forward in biotechnology, but at the same time, it involves the level of human morality and is a difficult problem that science cannot solve.

21st century.

1. Scientists publish a "working framework" of the human genome

Second, the United States has developed the most advanced quantum computer and biological computer.

3. The United States has developed 12 trillion supercomputers.

Fourth, the International Space Station welcomed the first long-stay astronauts.

5. Scientists discover neutrinos.

1 ZipperIn 1883, Witcomb Judson invented the zipper. This gadget, which is used by millions of people around the world in their daily lives, was first exhibited at the 1883 Chicago World's Fair, but it did not attract much attention when it was first exhibited, and it began to spread around the world in 1931, where it was widely used in wallets, handbags, backpacks, clothes and pants.

2 Integrated circuitsIn 1946, the first computer in the United States, weighing 30 tons, contained 18,000 vacuum tubes. At present, a single computer can do all of its functions and more. Vacuum tubes are constantly being replaced by smaller and more suitable transistors.

As a result, the size and weight of televisions and radios have also decreased, and the number of electronic devices has also dropped significantly. Eventually, integrated circuits replace all transistors.

3 AirplanesAircraft changed the twentieth century. People can travel farther, faster, easier, and more comfortably than before. In 1880, the fastest train ride from New York to Los Angeles took three months; It takes 6 months to take the fastest boat to detour South America. It's only a 6-hour flight today.

4 AirshipsBefore the advent of airplanes, airships were the only means of air transport for mankind.

5 Breathing Apparatus: Breathing in water was a dream of the ancients. In 1942, Castillon and the engineer Emile made the dream of the ancients a reality. They invented the scuba apparatus.

What's more, they invented the air conditioner. When the diver descends, the air regulator automatically adjusts the oxygen supply. Scuba apparatus has made a great contribution to the development of the oceans by mankind.

Air regulators will also serve the human exploitation of outer space.

6 The plaster bandage may be insignificant among the many inventions, but it is quite important. The plaster bandage was invented in 1936 and was first used for fracture reshaping. Prior to this, breaking a bone could lead to death.

7 Nylon 100 years ago, almost all clothing was made artificially from plant fibers or animal skins. In 1938, the American Nimol invented nylon. Within two years, parachutes began to use nylon cloth, and women wore nylon stockings.

Today, most fabrics contain a lot of nylon. Nylon is known as the ancestor of hundreds of synthetic raw materials used by us humans.

8 Rockets are widely used for meteorological exploration, the launch of various satellites and spacecraft. In 1924, the American Robert's small rocket shot only 220 feet into the air. Today's rockets can launch satellites to 10,000 miles of Kochi Zao and return to space.

9 Television In 1930, at the age of 21, Farnsworth invented a television system. On July 21, 1931, the world's first television broadcasting station was launched. At present, television is becoming more popular and developing.

10 RefrigeratorIn 1926, the Swede Platon invented the first refrigerator, which is a good helper for human life. Today, along with televisions, it has become an indispensable part of the electrification of many homes.

1. In the twentieth century, the greatest invention of mankind was the Internet, which made it convenient for people all over the world to communicate, and the world on which side of the earth became no longer mysterious.
