1. Nuclear fission
In the 1930s, a group of talented physicists discovered a method to generate amazing magnitude of energy through the fission of tiny uranium atoms. This discovery directly led to the appearance of the atomic bomb and changed the way of fighting forever. However, nuclear fission does not completely mean the end of the world and great destruction. Whether people love it or condemn it, nuclear power plants need to rely on fission science.
2. Space shuttle
1959, the Soviet unmanned spacecraft successfully landed on the moon for the first time and took a lot of photos. However, the feat of Apollo landing on the moon in the United States in the late 1960s was the first step for mankind to set foot on a planet other than the Earth's ball. After the appearance of the space shuttle, the chances of success of human beings going to outer space have greatly increased, and scientists predict that human beings will go to outer space in the near future.
Step 3: TV set
1923, the soul of television CRT was born. Television technology was widely used in the 1940s, and 1954 ushered in a new era of color television. After the 1960s, almost all countries established TV stations. This square box has created countless happy times for mankind.
4. artificial satellite
1 On June 4th, 957, the Soviet Union successfully launched the first artificial satellite, followed by American explorers 1 June, 19581. Since then, these artificial satellites have been floating more and more outside the atmosphere. Satellites were originally used in military science and technology, and gradually evolved into a family of satellites with different purposes such as communication, mapping, detection and meteorology.
Aspirin
As early as15th century, Greek doctors used the powder ground from willow bark as the prototype of herbal aspirin. By the end of the 20th century, this prescription for relieving physical pain had received unprecedented attention. The trademark "aspirin" founded by Bayer Pharmaceutical Factory in Germany has become a proper synonym for this prescription. In the increasingly busy modern society, aspirin, a white round pill, has played an indispensable role.
6. Civil airliners
In modern life, the necessary means of transportation for international travel-airplanes-are mostly commercial passenger planes converted from military transport planes. 1949, the first commercial airliner flew over Europe with 36 passengers, which opened a new phase in the civil aviation century. Nowadays, the demand for air travel in the transportation market is increasing, and civil airliners have become one of people's convenient means of transportation.
7. Personal computers
The third revolution of computer completely changed the way people work and think. In the late 1970s, computer manufacturers began to develop smaller personal computers, and in the early 1980s, popular computer consumer products appeared on the market. Personal computers have accelerated the pace of social digitalization, and almost every level of society is completely infected by computers. No one can refuse computers to enter life.
8. Mobile phones
The "mobile phone", which used to be the exclusive equipment of the heavyweights in movies, has now become a private communication method for people outdoors. The development of global economy makes mobile communication one of the hottest industries in recent years. The convenience that mobile phones can communicate anytime and anywhere has also changed the traditional way of communication between people.
9. cloned sheep
1At the beginning of 997, British scientists successfully gave birth to a lamb without a father. This pioneering work shows that it will soon be possible for human beings to create life by means other than natural means. Cloning sheep is undoubtedly an unprecedented progress in biotechnology, but it involves the level of human moral concepts, but it is a difficult problem that science cannot clarify.
10. Internet
The most primitive computer network, at first, only connected different computer hosts in the research room of the college. When this technology can be used by people simply by connecting modems and telephone lines, the network immediately became the most influential invention at the end of this century. The new information dissemination mode created by the network has rapidly affected more and more levels. E-mail, online shopping and online dating have redefined the network. People can connect the whole world in their hands with a thin network cable.
