Human beings grow up in social development, and human thinking is constantly trying in development. Things are organic combinations, and biological or abiotic things can change people's views on them. Using these to create what people need is called technology. Using it on the basis of science and technology is called innovation. Innovation is diversified, and if it is used well, it will certainly benefit mankind.

People also have two sides, and their ability to observe and judge things is instantaneous. For example, Newton's law of universal gravitation is obvious to ordinary people. No one thought, no one analyzed. Before Newton appeared, people thought that "theism" was "benefiting" people. This foolish idea has no scientific basis. However, Newton happened to find apples falling from the sky, and thought that one of them had some kind of "power", and this power came from outside the earth. At that time, no one dared to imagine these so-called things outside the earth. It was Newton who discovered this falling body that led to the so-called technology. There are many such things, for example, radar is invented by using the echo of bats, and ultrasound is invented by using the sound of dolphins.

The charm of science and technology exists not only in some living objects, but also in inanimate things. People can choose technology. If we innovate simple things and use them in useful places, we can create many new things, such as the invention of lasers, electric lights and computers. We all know Bill Gates. Without his invention, the computers we know would only be typing, computers and these simple things. These may be unknown so far, so they have changed from single to multiple.

However, due to human innovation in things, some things are harmful to the native earth, and the increase of carbon dioxide is harmful to the environment. Therefore, we should pay attention to protecting the environment while inventing many new things, otherwise the near future will be like the "20 12 doomsday" mentioned in the book, and this result is not what anyone wants.

With the rapid development of 2 1 century, we must understand the beauty, charm, frontier and beautiful things brought by science and technology, but it is not enough to rely solely on science and technology. These so-called technologies are all created by human beings themselves. While new things are constantly replacing old things, we must understand what is good. Using good things in useful ways will certainly develop and bring good and positive things to people, so we believe in the power of science and technology.
