1. Atomic bomb
In August 1945, the Bodora box that destroyed the earth was opened in Hiroshima and Nagasaki, Japan.

2. Space Shuttle
In 1959, the Soviet Union’s unmanned spacecraft successfully landed on the moon for the first time and took back a large number of photos. The United States' Apollo moon landing in the late 1960s was the first step for mankind to set foot on a planet beyond the earth. Since then, the United States has gradually left the Soviet Union behind in terms of space exploration. After the emergence of the space shuttle, the chance of success for humans to travel to outer space has been greatly improved. Scientists predict that humans will carry out outer space travel after 2000 AD.
3. Television
In 1923, the picture tube, the soul of television, was born. Television technology was widely used in the 1940s, and the era of color television was ushered in in 1954. After the 1960s, most countries have established television stations. This square box has created countless happy moments for mankind.
4. Artificial Satellite
The first artificial satellite was successfully test-launched by the Soviet Union on October 4, 1957, followed by the American Explorer 1 on October 1, 1958. The test was successful on March 31. From then on, more and more of these artificial satellites that orbited with the rotation of the earth were floating outside the atmosphere. Artificial satellites originally used in military technology have gradually evolved into a family of satellites with different purposes such as communication, mapping, detection, and meteorology.
5. Aspirin
As early as the 15th century, Greek doctors used powder ground from willow bark as the ancestor of the herbal version of aspirin. By the end of the century, this formula for relieving body pain received unprecedented attention. The "aspirin" trademark created by the German pharmaceutical company Bayer became the exclusive pronoun for this prescription. In the increasingly busy modern society of the 20th century, Aspirin Spirin, the white, round tablet, played an integral role.
6. Civil Aviation Passenger Aircraft
Airplanes, an essential means of transportation for international travel in modern life, are mostly commercial passenger aircraft modified from military transport aircraft. In 1949, the first commercial passenger aircraft flew over Europe with 36 passengers, opening a new page in the civil aviation century. Today, the transportation market has an increasing demand for air travel, and civil aviation has become one of the most convenient means of transportation for people
7. Personal Computers
The first revolution started by computers The three revolutions completely changed the way people work and think. In the late 1970s, computer manufacturers began to develop smaller personal computers. By the early 1980s, popular computer consumer products were on the market. Personal computers accelerate the pace of social digitization, and almost every level of society is completely infected by computers. No one can refuse computers to enter their lives.
8. Mobile phones
Once the exclusive equipment of big brothers in heroic movies, the "big brother" has become a private communication method for people during outdoor activities. The development of the global economy has made mobile communications one of the hottest industries in recent years. The convenience of mobile phones to communicate anytime and anywhere has also changed the traditional way of communication between people.
9. Cloning sheep
In early 1997, British scientists successfully gave birth to a lamb without a father. This pioneering work demonstrated that it would be possible for humans to create a lamb by methods other than natural methods. life. Cloning sheep is undoubtedly an unprecedented step in biotechnology, but it involves human moral concepts. But it is a difficult problem that science cannot sort out.
10 Internet
The most primitive computer network was originally just a connection between different computer hosts in college laboratories. When this technology only required connections through simple modems and telephone lines, When it became available to people, the Internet instantly became the most influential invention at the end of the century.
