This paper mainly discusses the problems of cognition, logic and natural science. Mo Jing contains rich knowledge about mechanics, optics, geometry, engineering technology and the basic elements of modern physics and mathematics. Among them, the balance and force system of force and simple machinery such as lever and inclined plane are discussed.
The observation and research of pinhole imaging and plane mirror, concave mirror and convex mirror imaging are recorded, and the concepts of time ("length", that is, week) and space ("redundancy") are put forward for the first time.
Mozi is the first person in China history who has profound attainments in many fields, such as the function of force, lever principle, direct light, the relationship between light and shadow, pinhole imaging, the concepts of point, line, surface and circle. Mo Jing is the earliest work on geometric optics. Mo Jing, also known as Mobian, mainly discusses epistemology, logic and natural science.
Mo Jing is an important part of Mozi, which was completed in Guisi in 14 (388 BC). Mozi is a Mohist work of China during the Warring States Period, written by Mo Zhai and his disciples.
Mo Jing consists of four chapters: classic, classic, classic and classic (including six chapters of Daqu and Xiaoqu). Jing Shuo is an explanation or supplement to Jing Shuo. Others think that the classics were written by Mo Zhai, the founder of Mohism, and recorded by his disciples.
Logic accounts for the largest proportion in Mo Jing's content, followed by natural science, with more than 10 in geometry and about 20 in physics, mainly including mechanics and geometric optics. In addition, there are regulations on ethics, psychology, politics and law, economy and architecture.
Brief introduction of the author
Mozi, named Zhai, was a Song poet in the late Spring and Autumn Period and the early Warring States Period. A descendant of Mu Yi, a noble in the Song Dynasty, once worked as a doctor in the Song Dynasty. China was an ancient thinker, educator, scientist, strategist, founder and main representative of Mohism.
Mozi is the only philosopher born as a farmer in the history of China, who founded Mohism. Mohism had a great influence in the pre-Qin period, and it was also called "outstanding learning" with Confucianism. Established a set of scientific theories and made outstanding achievements in geometry, physics and optics. During the Warring States period, a hundred schools of thought contended, which was called "non-Confucian Jimo".
