Do you know that you can use technology to grow colored cotton? Have you seen the paper made of stone? On the afternoon of October 16, the Guangzhou Academic Association and the Guangzhou Municipal Education Bureau hosted the “Academician Expert Campus” hosted by the Guangzhou Youth Science and Technology Center to enter the Rui'an Campus of Longkou West Primary School in Tianhe District. Professor Chen Heneng of the Chinese Academy of Sciences and the Academy of Sciences Grade students talk about the magic of technology in life. Professor Chen not only vividly displays the changes brought by invention and creation to people's lives by using pictures and videos, but also brings technology products and stimulates students' enthusiasm for exploring the world of science and technology.

Technology-changing life

“Classmates, do you know how the velcro on the shoes was invented?” At the beginning of the lecture, Chen He was able to sneak out the science and technology issues related to life and lead the students to think. When some students thought that the Velcro was a pasting technique, Chen He could uncover the mystery with the enlarged picture details. The "Velcro" was originally composed of a small hook.

What did the scientist get inspiration from and invented the "magic patch"? Chen He can play a video on the spot. A puppy passes by the burdock and the body is covered with burdock. When you look at the magnifying glass, you will find many small hooks that will catch the passers-by's clothes or pants. The scientist's inspiration comes from the hook of the burdock.

There are many research and development achievements of modern people in the food, clothing, housing and transportation of modern people. Then, Chen He can introduce the wearing close to life, and now the clothing factory dyeing clothes is easy to cause pollution. Nowadays, scientists are using the technology of gene transduction and hybridization to try to cultivate "color cotton", hoping to eliminate the polluting environment.

After finishing the "clothing", Chen He was still unable to do so, and continued to talk about "living" that is closely related to life. “Of our original ancestors lived in caves, and later lived in grass houses. Then there were brick-built houses. The height of the houses was getting higher and higher, and there were many hundreds of skyscrapers.” Chen He can use video to show In the near future, there will be a rotating skyscraper, a large circular shaft made of new materials, which controls the whole building to rotate slowly around the axis, so that each layer can be rotated slowly according to the user's instructions, seeing different scenery, but also the future of a variety of different shapes of houses by 3D printer device called a "print" them.

Science and technology research imagination is very important

In the lecture, Chen He was able to invent the invention from hybrid rice to colored cotton, from unbreakable stone paper to a rotating house to a 3D printing room, detailing the various aspects of science in people's clothing, food, housing, transportation and use. magical effect.

In addition to pictures and videos, Chen He can bring life-related technology products to students for close contact. A box of brown cotton that he brought back from Xinjiang allowed the students to pass observations. He brought a piece of paper made of stone. Scientists invented stone-made paper for environmental protection to replace traditional logging and papermaking. This stone paper has several advantages: tear resistance, folding resistance, no water, high paper quality and cost. Low and environmentally friendly. Several students took turns to experience this stone paper and it is not easy to tear.

Professor Chen Heeng said that the inspiration of scientists is generally from life, and careful observation can only be found. He also stressed that imagination is also very important. For example, scientists have observed the spider's silking, inspiration, and invented the machine that spits cement to build a house. The efficiency of building a house is greatly improved. He encourages students to learn to observe and remain curious, and they will have their own innovations in the future.
