Footsteps of science and technology essay 500 words

At 21:10 Beijing time on September 25, 2008, China's Shenzhou-7 manned spacecraft was successfully launched at the Jiuquan Satellite Launch Center, which once again carried the century-old space dream of the Chinese people and the crystallization of the wisdom of the Chinese people, and flew into the distant universe. China's science and technology has taken another solid step. From a country with backward science and technology to a country with developed science and technology, China has gone through a long process.

Science and technology carry the hope of national rejuvenation and symbolize the strength of a nation. Technology is the carrier of dreams, it is like a free eagle, people have released it with the hand of creation, so it has become the best in the blue sky. For thousands of years, it has led society from poverty to development, from ordinary to extraordinary.

People who have the dream of science and technology are the carriers of heroic qualities, and those who can truly contribute to the development of science and technology are heroes.

Everyone knows that Yang Liwei, the aerospace hero of "Shenzhou 5", no one denies that he is a veritable hero. But if you ask everyone why he is a hero, maybe people's answers will be varied. But what is certain is that people's answer must be inseparable from China's space industry.

China's aerospace industry is the best symbol of China's scientific and technological greatness, from Shen V to Shen VII, from one astronaut at the beginning to three now, China's space industry is gradually maturing. China, no longer the country that was once called the sick man of East Asia by foreigners, has proved itself with its technological prowess, "Wait, those who once looked down on me!" I'm going to show you what the highest level of creation is!

If technology is a solid building, then creativity is the indispensable solid cement for building a building. Without great creation, technology cannot flourish. The great inventor Thomas Edison, who completed many inventions and creations in his lifetime, relied on his flexible thinking, creative talent and hard work to achieve his life, and his creations were among the best in the world, so he naturally became a giant in the scientific world.

And sometimes, technology requires sacrifice. Many scientists have given their lives for the advancement of science and technology. Edison once caused trouble in his neighbors because of his research, and even had his younger brother sacrifice his precious life, but he made compensation for these sacrifices and made great contributions to the world's science.

Technology and dreams are single-plank bridges and river banks, and only by conquering the steep and dangerous single-plank bridges can we reach the other side of dreams.

On the occasion of the advent of the science and technology community of Huaying School, we sing the song of science and technology, release the white dove of dreams, let the song fly with the wind, and let the white pigeon fly freely! Let's fly science and technology and achieve our dreams!

If you feel satisfied, !

There are many things that belong to technology around us, such as rice cookers, computers, televisions, and electric lights. Our science is really getting more and more advanced, and this is all created by everyone's efforts.

Science has brought us many benefits and made our lives better! The efforts of the scientists were not in vain! The former yellow mud road, mud road, and cement road have evolved into today's asphalt roads, which means that our transportation has improved.

The moonlight, fireflies, oil lamps, coal-staring oil lamps have evolved into today's electric lamps, which means that our fire lamps have progressed. Now there is a new thing, the specific situation is like this: recently, I found that our road will be chaotic and there are cars running traffic lights, so I installed a camera, once a car crosses the red light, a fine of 200 yuan will be fined that thing will take pictures of the scene at that time, !

My uncle is an example of this, and now we can all cross the street with peace of mind because of the curiosity of my cousins! It's so convenient!

We have cars walking on the road, ships on the sea, planes and rockets in the sky, ......Having gotten rid of the "two-legged car", this is the progress of science. Science will make us a good life!

Ahhhh
