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. As early as more than 2,300 years ago, Mozi, an ancient thinker in China, contained rich knowledge of mechanics, optics, geometry, engineering technology and basic elements of modern physics and mathematics.
The value of Mo Jing
What Mo Jing actually recorded also involved optics, mechanics and so on. In optics, Mo Jing discussed the pinhole imaging principle of light and pointed out the straight-line propagation law of light. Mohist classics also recorded the phenomenon of hydrostatics, and initially formed the idea of buoyancy principle.
Mo Jing also recorded many technical inventions and methods of Mohism. Including the application of the "ladder" of the crown block, the "wooden chariot and horse" that can walk freely on the road, and twelve methods of guarding the city to prevent the enemy from attacking.
The value of Mo Jing's thought also lies in that it marks that some outstanding thinkers in ancient China have been able to generalize and rise to abstract theories through direct observation and experimental phenomena, and this way of thinking is just a powerful driving force for the rapid development of western science.
