Science and technology have progressed, and things are not people

Technology is constantly evolving, and it is constantly improving. It has brought a lot of help to people's life, study and work.

With the change of the times, the change of people's thinking, and the development of science and technology, every family has high technology.

Now, scientists have developed one of the world's fastest hydrogen-fueled vehicles. Not only does the car save hydrogen fuel, it doesn't pollute, it also travels at high speeds, with a minimum speed of 80 kilometers per hour and a maximum speed of 100 kilometers per hour. The car set a new world record with just 2 kilograms of hydrogen fuel to travel from Berlin to Barcelona.

A hydrogen-fueled car has only three wheels, and its air resistance is only half that of a regular sedan. Now, with this kind of car, you are not afraid of the pollution of the environment from the exhaust gas emitted by the car!

Now, there is also a light-emitting diode flashlight. This kind of flashlight is much better than a regular flashlight. There are 3 reasons why LED flashlights are better than regular flashlights.

One is: the lighting distance of this flashlight can reach 40 meters, while the ordinary flashlight can only reach one or twenty meters. The second is:

Its lighting time, a pair of No. 5 batteries can be used for 20 hours, while a regular flashlight can only be used for 2 hours. The third is: the life of an ordinary flashlight is one-tenth of that of a light-emitting diode flashlight.

With this flashlight, you can reduce the damage of the battery to the environment.

Recently, the United States has developed a new type of robot. This robot can do housework, can organize materials, etc. It is a "good helper" in people's lives.

Technology is constantly evolving, and it is constantly improving. It has brought a lot of help to people's life, study and work.

Technology and humanity fly together.

The bell of the end of the 20th century is about to ring, and mankind is about to enter the ever-changing and unpredictable corridor of the 21st century. How to face this complicated and rapidly developing new century? How can we humans control our future destiny?

I believe that this should attract the attention of the Organizing Committee of the World Expo, and highlight this content at the World Expo.

Therefore, the theme I have set for Expo 2010 Shanghai is:"Science and technology and humanities fly hand in hand. "

Since the birth of human beings, they have had two things: science and technology and humanities, from the earliest drilling wood for fire and carving stone and chiseling walls, to today's computer technology and increasingly developed humanities and human traditions, human beings continue to benefit from them, and through these two ** to produce a strong driving force, from Ru Mao to the information age, the role of the two is self-evident, and the relationship between the two is like the two ends of the balance can not be wasted, indispensable. Especially for today's situation, the combination of science and technology and humanities is even more important.

This is an inevitable need to accelerate the development of today's times. In this day and age, science has advanced to a considerable level. Computer networks and information technology, human genome engineering, the protection and utilization of resources, the overcoming of various terminal diseases, and so on, all these developments are the embodiment of the rapid development of science and technology today, giving mankind hope and bottom-up motivation.

At the same time, the development of science and technology has had a huge impact on values and ethics. Whether cloning technology can be applied to human beings, and whether genetic technology can be used indiscriminately and bring disaster, these questions have brought a lot of anxiety and panic to mankind. At this time, mankind urgently needs the humanities to take charge of itself, solve all kinds of confusion on the road of human development, and remove ideological and moral obstacles, just as Marxism brought new hope to China in those years.

The equal importance and complementarity of the two can be seen.

This is also an inevitable need to improve the quality of all mankind. In the final analysis, the whole world is a combination of individuals and people. For the sake of world peace and development, the role of the individual cannot be turned a blind eye, and the quality of the individual also needs to be improved urgently, so as to bring about the improvement of the quality of all mankind.

Such a task is particularly daunting for developing countries. This requires the strengthening of the individual"Two civilizations"It is necessary to arm people with modern scientific and cultural knowledge and a correct world outlook on science and technology and humanities, so that they can become perfect people. "As long as people are perfect, the world is also perfect"This wishful thinking and beautiful ideal should also become our goal.

It's a bit difficult to write.

It's too time-consuming、...

Science and technology are the primary productive forces, and the development of productive forces is the fundamental driving force for the development of human society.

1. The use of natural fire is the first milestone for the evolution of Australopithecus into apes.

2. Drilling wood to make fire, completing the evolution from ancient apes to apes.

3. The use of stone tools and the manufacture of stone tools opened the door to the transition from apes to humans, and apes finally became humans, and humans became masters of nature. Humanity entered the Paleolithic and Neolithic periods. With surplus products, with commodities and commodity exchange, with commerce, humanity enters class society.

Enter a primitive society.

4. Since mankind mastered the smelting technology of bronze and iron, it has greatly liberated the social productive forces, promoted human society into the metal age, and made human beings enter the slave society and feudal society.

5. The invention of the steam engine once greatly liberated the productive forces, enabled mankind to enter the industrial revolution and the era of large-scale machine production, and produced the great modern productive forces of capitalism, which inevitably required the establishment of capitalist production relations, and the bourgeoisie overthrew the landlord class and established the capitalist social system.

6. The invention of gunpowder enabled human beings to split mountains and open roads, build bridges, and build, and promote the great development of various undertakings. The rapid development of the military industry has enabled mankind to enter the era of hot weapons from the age of cold weapons.

7. With the advent of papermaking and printing technology, human beings have the conditions for writing, and have promoted extensive exchanges in culture, art, language, science and technology, economy, etc.

8. The creation of the compass promoted the development of navigation and the completion of geographical discoveries. Mankind has come to know the earth.

9. The scientific and technological achievements of hybrid rice and super rice have greatly increased grain production and solved the problem of feeding the world's population.

10. The invention of electricity has enabled mankind to enter the age of electrical appliances and once again stimulated the tremendous development of productive forces. Bring light to the world.

11. The discovery of radio waves has led to a series of major inventions, such as the popularization of television, mobile phones, etc., which have greatly enriched the material and cultural life of the people.

12. The creation of computers has brought the world into the information age and shortened the distance between the world.

13. The successful development of satellites and spacecraft has enabled mankind to leave the earth and develop space. Make the earth smaller and smaller.

14. The successful development of China's parasitic satellite and other anti-satellite satellites has made mankind face a space war.

15. Genetic engineering should bring human beings to the era of Cologne.

That's where marathons come from, brother.
