Kant said; "There are two things in the world that are most awesome, that is, the starry sky overhead and the morality in the heart." The starry sky above can be understood as nature. Since the emergence of mankind, people have never stopped exploring nature, nor have they stopped understanding and upgrading themselves.

About 500 years ago, modern science and technology began to sprout in Europe and developed by leaps and bounds. The extensive application of new technology, the further liberation of ideas, the gradual establishment of scientific system, the gradual improvement of scientific methods, the gradual expansion of scientific fields, and more importantly, the scientific spirit of seeking truth from facts has been carried forward.

The process of scientific development is very tortuous and difficult, and scientists' research and work do not always get applause and flowers. When discussing the truth of nature, they often need to make superhuman efforts, often conflict with the inherent stereotypes, and sometimes even pay the price of blood and life. These past stories are still so touching today.

Nowadays, young people have a heavy burden of study. While studying a lot of textbooks, we should also go out of the classroom, relax, read extra-curricular books, learn some popular science knowledge, improve our scientific quality and broaden our horizons. Let science add some color to our life.

This set of books tries to carry forward the scientific spirit, advocate scientific methods and popularize popular science knowledge. It is precisely because of these that this set of books has become a vivid teaching material that inspires life wisdom in all directions and has become a colorful and interesting movement about science in a region. This set of books shows all aspects of science and the complete image of science in an all-round way, avoiding taking the' common sense' of science and technology as a textbook. Doing so is not only boring, but also turns the long, tortuous and arduous road of many scientific inventions and discoveries into short, straight and easy flowers; Scientific spirit, scientific belief and scientific method have all disappeared.

This set of books does not use boring records and boring sermons, but uses vivid and touching stories, or suspense and fascination, or mountains are heavy and waters are heavy, clouds cover the fog, or the future is bright, and cigarettes are sold at sunrise, so that we can appreciate the magical charm of science.

Let's listen to the touching scientific movement together, climb the ladder of science and step into the hall of science.
