The mathematical model of studying the law of thinking (logic, mathematical logic) put forward by the British mathematician G Bull in 1847 and 1854. Since then, R. Dai Dejin regarded it as a special case. Due to the lack of physical background, the research progress was slow, and new progress was made in the 1930s and 1940s. About 1935, M.H. Si Tong first pointed out that there is a clear connection between Boolean algebra and rings, which made Boolean algebra develop in theory. Boolean algebra has applications in algebra (algebraic structure), logical calculus, set theory, topological space theory, measure theory, probability theory, functional analysis and other mathematical branches. After 1967, it also played a certain role in the theoretical research of axiomatic set theory and model theory, a branch of mathematical logic. In recent decades, Boolean algebra has important applications in automation technology, logic design of electronic computers and other engineering and technical fields. 1835, 20-year-old george boole opened a private teaching point. In order to provide students with the necessary mathematics courses, he read some textbooks introducing mathematics knowledge with great interest. Soon, he was surprised. Are these things math? It's unbelievable. As a result, this young man with only preliminary mathematical training taught himself the difficult "celestial mechanics" and the abstract "analytical mechanics".
