1. The Elements of Geometry is an immortal work of Euclid, an ancient Greek mathematician, which integrates the achievements and spirit of ancient Greek mathematics in one volume. It is not only a masterpiece of mathematics, but also a masterpiece of philosophy, which completes the human understanding of space for the first time. Since its publication, it has been translated and revised for more than 2000 years. Since the first printed version of 1482 was published, there have been more than 1000 different versions. Apart from the Bible, there is no other work, and its research, use and dissemination are extensive, which can be compared with the Elements of Geometry. The earliest Chinese translation was completed by Italian missionary Matteo Ricci and Ming Dynasty scientist Xu Guangqi in 1607, but they only translated the first six volumes. It is this remnant that laid the basic terms of modern mathematics in China, such as triangle, angle, right angle and so on. Japanese, Indian and other eastern countries all use China's translation, which is still in use today. In the past century, although this masterpiece must be mentioned in Chinese mainland's middle school textbooks, it is not a blessing for China readers to see its whole picture, and it is even more wishful thinking to include it in family books. Xu Guangqi spoke highly of this book when he translated it. He said that whoever can master this book can master everything. Those who are eager to learn this book have nothing to learn. Einstein, the founder of modern science, even thought that if Euclid didn't arouse your scientific enthusiasm in your childhood, you would definitely not become a talented scientist. It can be seen that geometric elements have a great influence on people's rational deductive ability, that is, on people's scientific thinking.
2. This book is a world-famous popular mathematics reading. It brings together many classic mathematical treasures and profoundly and vividly expounds the basic concepts and methods in the whole mathematical field. Both math professionals and people who are willing to think scientifically can read, especially for middle school math teachers, college students and high school students.
