His works have precious historical and scientific value. For example, in the book Hardware, Song was the first scientist in the world to discuss zinc and copper-zinc alloy (brass) scientifically. He clearly pointed out that zinc is a new metal and recorded its smelting method for the first time. This is one of the important achievements in the history of ancient metal smelting in China.
In particular, Song paid attention to discovering essence from common phenomena and made some achievements in natural science theory.
First of all, in biology, he recorded the case of farmers cultivating new varieties of rice and barley in Wu Kai of Tiangong, studied the influence of soil, climate and cultivation methods on the variety change of crops, and noticed the variation caused by the hybridization of different varieties of silkworm moths, indicating that the variety characteristics of animals and plants can be changed through human efforts, and obtained the scientific view that "soil veins change at any time, and species are divided by water and soil".
In physics, the newly discovered chapter "On Qi, Qi and Sound" is an outstanding chapter in acoustics. Through the concrete analysis of various acoustics, Song studied the law of sound generation and propagation, and put forward the concept that sound is air wave. 9. Tiangong Wu Kai is an encyclopedia about agriculture and handicrafts. What points are emphasized and some strange questions are asked. Most of the records are practical science. For its evaluation, European cars call this book "17 century craft encyclopedia", which is quite high.
"It systematically summarizes various technologies in ancient China and constitutes a complete scientific and technological system. Summarized the rich agricultural experience and fully reflected the scientific and technological achievements. Many of the production techniques described in the book have been used until modern times. " This is the encyclopedia's evaluation of it. ...,0,
