Passers-by laugh at Xintiandi, Shenzhen High-tech Park, Peking University's romantic performance, and Tsinghua's charming. 3. Science and Technology Manuscript

We should learn science, love science and show it. But how can we do it? Scientists tell us that curiosity is one of the most important aspects of human nature and the main motivation to explore the mysteries of science; The best way to satisfy this strong desire is to have the courage to ask why, to try and innovate, to overturn the words and conclusions of predecessors, and finally to get your own results. For example, Galileo, Copernicus and others bravely pointed out the wrong arguments of their predecessors regardless of the pressure and opposition from all sides. Through personal practice and experiments, I proved that my point of view is correct, in exchange for my own success.

the average person's understanding of the word "science" may be understood as "the content of truth knowledge that human beings have found to represent reality" (concrete scientific knowledge) or "the theory of scientific truth" (scientific theory system), or "how to find and distinguish methods called scientific knowledge and scientific theory" (scientific method and scientific spirit), in which philosophy of science may also be included. In fact, an eternal problem in the existence and development of science is the contradiction between standards and innovation. On the one hand, the emergence of scientific knowledge is bound to form relevant standards for judging right and wrong. On the other hand, the process of scientific knowledge is a breakthrough process to the original standards, so it is bound to be restricted or suppressed by the original standards. 4. handwritten newspaper about science and technology

1. Why do the stars twinkle? We see the stars shining, not because the luminosity of the stars themselves changes, but because of the occlusion of the atmosphere.

The atmosphere is between us and the stars. When starlight passes through the atmosphere, it will be affected by the density and thickness of the atmosphere. The atmosphere is not absolutely transparent, and its transparency will change according to the density.

So when we look at the stars through it on the ground, we will see that the stars seem to be flashing. 2. Why do people yawn? When we feel tired, a lot of carbon dioxide has been produced in our bodies.

when there is too much carbon dioxide, oxygen must be added to balance the body's needs. Because these residual carbon dioxide will affect the functional activities of our body, then the body will send out a protective reaction, so it yawns.

yawning is a deep breathing action, which will make us breathe in more oxygen and expel carbon dioxide than usual, and it can also eliminate fatigue. 3. Why can snakes walk without feet? Snakes have many scales, which is the outermost layer of armor on their bodies.

Shenzhou II, a brand-new appearance:

Although Shenzhou II is the second unmanned spacecraft, it is the first prototype spacecraft in China, and it can also be said to be the "most complete version" of the manned spacecraft, and all kinds of technical conditions are basically the same as when manned. The spacecraft returned to the ground after seven days in orbit. Experiments in the fields of space life science, space materials, space astronomy and physics in microgravity environment have been carried out on the spacecraft. Various instruments and equipment have stable performance and work normally, and a large amount of data has been obtained. The technical status of the spacecraft is basically the same as that of the manned spacecraft.

Space knowledge:

At 14:22 on June 18th, China embarked on the road of reform and opening up in 1978. Reform and opening up have stimulated the vitality of all walks of life, and made China's productive forces develop continuously. One by one, emerging cities have sprung up. Major scientific and technological achievements have been manufactured and developed. One large-scale project was completed. Super-large enterprises are growing rapidly. China has grown tall and strong. It is no longer the poverty and weakness of the 194s and 195s, nor the poverty and backwardness of the 196s and 197s! The successful launch of Shenzhou VI spacecraft this morning is another major achievement of China's social development since the reform and opening up!

Information about the space shuttle:

The space shuttle is a winged, reusable rocket-powered spacecraft. It was launched from the atmosphere by an auxiliary launch vehicle as a means of transportation between the earth and outer space. The space shuttle combines the properties of aircraft and spacecraft, like a spacecraft with wings and looks like an airplane. The wings of the space shuttle provide air braking when returning to Earth and lift when landing. Like other single-use vehicles, the space shuttle ascends vertically with rocket power. Because of the wing, the payload ratio of the space shuttle is low. After more than 2 years of use, it is found that the cost necessary to ensure the reliability of the space shuttle is too high, which is close to being eliminated.
