First, science and technology are the primary productive forces.
Throughout the ages, every progress of human society is accompanied by the progress of science and technology. In particular, the rapid development of modern science and technology has opened up a broader space for the development of social productive forces and human civilization and effectively promoted economic and social development. The rapid growth of computer, communication, biomedicine, new materials and other high-tech enterprises in China has greatly improved China's industrial technology level, promoted the improvement of industrial and agricultural labor productivity, and effectively promoted the development of the entire national economy. Practice has proved that high-tech and its industries have become the leading industries in contemporary economic development. Science and technology are the symbols of human civilization. The progress and popularization of science and technology have provided mankind with new means to spread ideas and culture, such as radio, television, movies, videos and the Internet, which has given spiritual civilization a new carrier. At the same time, it is of great significance to enrich people's spiritual life, update people's ideas and get rid of superstitions.
According to experts, according to the action mechanism of contemporary science and technology and productivity, the relationship between science and technology and various elements of productivity can be expressed by the following formula: productivity = science and technology × (labor force+labor tools+labor object+production management). The above formula shows that science and technology are not only real direct productive forces, but also have a special position in various elements of productive forces. The multiplication effect of science and technology strongly expresses its primary position and role in productivity.
Second, concrete scientific achievements.
1. Great achievements have been made in human genome research. On February 12, 2000, scientists from six countries participating in the Human Genome Project jointly published the human genome map and its analysis results. The complete map of the human genome will be completed this year. Draw a complete human genome map and decipher all human genetic information. The implementation of this plan will continue to provide diagnosis and prevention of human diseases, bring immeasurable changes to the pharmaceutical industry, and promote the development of life science, information science and a number of high-tech industries.
2. Great achievements have been made in the field of nanotechnology. Scientists in China are at the forefront of international science and technology in nanotechnology research. Recently, scientists in China have directly discovered the "peculiar" property of nano-metals-superplastic ductility for the first time in the world. Nano-copper can be stretched more than 50 times at room temperature, which is known as "a breakthrough in this field, and it shows people for the first time how void-free nano-materials are deformed". Generally speaking, China ranks fourth in the world in the total number of nano-papers, and has occupied a place in the international research of nano-materials.
2. Supercomputer "Tianhe No.1" 2010110/October, Tianhe No.1 set the world record for the fastest computer in world record association. As the inventor of this ancient calculator, China has the fastest computing tool in history.
The measured performance of Linpack is 2507 trillion times per second. This speed means that if "Tianhe No.1" is used to calculate one second, it is equivalent to the continuous calculation of 88 years by 654.38+03 billion people in the country. If "Tianhe-1" is used to count one day, a current mainstream microcomputer will count 160 years. The storage capacity of "Tianhe No.1" is equivalent to the total collection of four national libraries.
3. National 863 Plan
Since the implementation of1986 "863" project in March, * * * has obtained more than 2,000 patents at home and abroad, published more than 47,000 papers, created a cumulative new output value of more than 56 billion yuan, and generated indirect economic benefits of more than 200 billion yuan. The overall gap between the R&D level in the high-tech field supported by the 863 Program and the world advanced level has obviously narrowed, and it has begun to occupy a place in the world high-tech field. More than 60% of the technology has grown from scratch, and now it has entered or approached the international advanced level, and 25% still lags behind the international advanced level, but it has also made great progress on the original basis.
4. You also have an avatar.
Imagine that you can come to a three-dimensional virtual conference room or classroom without leaving your room or office and sit with many colleagues from Avatar. After careful design, Avatar can perform better than itself; When your head is nervously taking notes at your desk, you are still sleeping in your bedroom.
It sounds like an advertisement in the future, and according to The New York Times's April 12 report, two persons in charge of virtual reality research at the University of California and Stanford University said that a 3D conference technology involving body double is close to maturity. According to their vision, personal "Avatar" will appear soon, and virtual body double technology may become a reality in the next five years. They designed the body double for a man named Dave. Dev himself is lazy to sleep, while his body double attends the company meeting at 8 am. "Put on a digital Italian suit and become a perfect participant. He will capture the voice changes of other body double, judge whether it is a joke or a laugh, and nod his head in agreement at an appropriate time, faithfully recording every detail in the conversation. "
5. New materials for preventing nuclear radiation
According to the April 14 (Beijing time) report of the American Physicist Organization Network, researchers at the University of North Carolina in the United States recently discovered that a compound composed of forestry by-products and crustacean shells may help us filter out radioactive pollutants in water. It is easier to discharge pollutants than to clean them up. The radiation leak in Fukushima made half the world nervous, buying iodine tablets and grabbing salt. If the above-mentioned radioactive iodine collection technology has existed for a long time, it is the "filter bag" that sells out of stock. Although it is half a step late, it is gratifying that biomaterials have broad prospects in environmental protection applications. In addition, the public needs scientists to provide more methods to remove radioactive cesium and other substances that threaten for a longer time; The public also hopes to have a set of mature nuclear accident handling technology-otherwise the situation will get out of control like the Fukushima reactor; The most fundamental thing is that we hope that there will be no more problems in nuclear power plants. High-tech can save lives and hurt people, and sometimes we can't afford to hurt them.
3. Is nuclear radiation terrible?
"In the event of nuclear radiation, the two systems of the human body are the most vulnerable." Chen Hu, director of the Hematopoietic Stem Cell Transplantation Center of the 307 Hospital of the People's Liberation Army, said that the reproductive system of the human body is the most sensitive. Nuclear radiation will first damage sperm and eggs, even if it does not cause radiation sickness, it will also cause hereditary diseases due to low-dose radiation. The second is to damage the hematopoietic system, which already belongs to the category of radiation sickness. It is divided into mild, moderate, severe and extremely severe, and the first three can be treated. "In fact, the radiation dose leaked from Japan this time is far from reaching the level of radiation sickness. More than 100 officially notified radiation patients are only polluted by radioactive dust, and the risk of illness can be completely avoided after cleaning and other treatments. " In this regard, China's folk science organization "Science Squirrel Club" has also been converted, and the real-time data monitored by the Fukushima nuclear power plant leakage is 1.0 15 millisieverts per hour. This is equivalent to: 1. Industrial radiation received by nuclear power plant workers within one year; 2. X-ray examination of radiation; 3. Exposure to air radiation for 239 hours; 4. Natural radiation received by everyone within half a year. According to the exact data, only 28 firefighters died of acute external radiation in the Chernobyl nuclear accident of magnitude 7. Many experts have said in the media that' people may die if exposed to radiation above 6000 millisieverts', but they have not explained an important premise, that is' acute one-off whole body external irradiation'. Wang Zhongwen said: "So, even if Japanese nuclear pollution spreads to China, there is absolutely no need to panic, because the radiation has been diluted to a level lower than that in the daily environment."
So, how to avoid the harm of nuclear radiation? Shi Hongcheng, director of the Department of Nuclear Medicine, Zhongshan Hospital affiliated to Fudan University, suggested that even in areas with radioactive pollution level 4, as long as the protection is proper, the radiation dose to the human body is within the safe range. For example, cover your nose and mouth with a handkerchief, towel, cloth, etc. Once it rains, radioactive substances entrained in the air will fall to the ground or people, and try to stay indoors; People who may be contaminated by radiation should be cleaned up. The best way is to take a bath, especially to clean the mouth, nose and hair, because some radioactive substances can be absorbed through the skin and mucous membranes. In areas with serious radioactive pollution, you can wear hats, headscarves, glasses, raincoats, gloves and boots, which will help reduce radioactive pollution on the body surface; Don't eat polluted water, food, etc. High-risk personnel need oral iodine.
Fourth, Shenzhou Tian Fei.
China's "Three Steps" Plan for Manned Space Flight
The first step is to launch unmanned and manned spacecraft. With the safe return of China's first astronaut Yang Liwei on June 65438+1October 65438+June 2003, the first mission has been completed.
The second step is to continue to break through the basic technology of manned space flight: multi-person and multi-day flight, astronauts walking out of the cabin and completing the rendezvous and docking of the spacecraft and the space capsule. The launch of Shenzhou VI and Shenzhou VII indicates that China is implementing the second-step plan of manned spaceflight project.
The third step is to establish a permanent space laboratory and space engineering system in China, where astronauts and scientists can travel between the Earth and the space station and conduct large-scale space science experiments.
It is expected that Ba Shen will dock with Tiangong-1 in the second half of this year.
China Aerospace Science and Technology Corporation said that at present, major national science and technology special development tasks such as Tiangong-1 target aircraft, Shenzhou-8 spacecraft, Chang 'e-3 lunar lander and Long March-5 new generation launch vehicle are progressing smoothly as planned. The rendezvous and docking mission between Shenzhou-8 spacecraft and Tiangong-1 target aircraft, which will be launched in the second half of this year, is also being successfully implemented.
Other plans
In addition, the successful launch of Chang 'e-2 satellite laid a solid foundation for realizing the goal of "lunar patrol survey" in the second phase of China's lunar exploration project; The first-phase networking construction of Beidou satellite navigation system entered the stage of full implementation; The operation of Fengyun-3 A/B double-star network and the successful launch of Xinnuo-6 satellite have further improved the level of meteorological forecast and the ability of safe broadcasting of radio and television in China.
