My father is a writer and a member of the War College, which greatly influenced his early education. He was clever and curious since he was a child. It is said that he later deduced more than 400 inferences from this. At the age of 17, he wrote The Theory of Conic Curves (20 12), which is a paper on the projective geometry of Gilad Girard Desargues, including the above theorems.
These works are the greatest progress of cone theory since apollonius. 1642, he designed and made an automatic addition and subtraction computing device, which was called the first digital calculator in the world, and provided the basic principle for computer design in the future. 1654 began to study several mathematical problems, deeply discussed the principle of inseparability in infinitesimal analysis, obtained a general method to find the area and center of gravity surrounded by different curves, and solved the cycloid problem with the principle of integral calculus, which was completed on the cycloid in 1658.
The manuscript of his thesis has great inspiration for gottfried leibniz to establish real integral. While studying the properties of binomial coefficients, he wrote Arithmetic Triangle and submitted it to the Paris Academy of Sciences. Later, it was included in his complete works and published in 20 1 1. The binomial coefficient given in it was later called Pascal Triangle, but it was actually known by Jia Xian of China about 1 100 years ago (namely Jia Xian Triangle). Talking with pierre fermat about the allocation of gambling money has a great influence on the development of early probability theory. He also made a mercury barometer (1646) and wrote a paper on liquid balance, air weight and density (1651-kloc-0/654). Starting from 1655, he lived in seclusion in a monastery and wrote classic works such as My Thought (1658).
