The argument between Leibniz and Newton who invented calculus first is the biggest case in mathematics. Leibniz published the first differential paper in 1684, defined the concept of differential, and adopted the differential symbols dx, dy. 1686 published an integral paper, discussed differential and integral, and used the integral symbol ∫. According to Leibniz's notebook, he has completed a complete set of differential calculus in 1675 1 1.
2. Topology was first called "analytical position" and was put forward by Leibniz in 1679. It is a subject that studies topography and landforms. At that time, I mainly studied some geometric problems arising from the needs of mathematical analysis.
3. Leibniz is also the peak of European rationalism philosophy. He inherited the thought of western philosophical tradition and thought that the world must be composed of self-sufficient entities because of its certainty (in other words, the knowledge about the world is objective, universal and inevitable). The so-called self-sufficiency means being recognized without anything else.

Leibniz once came into contact with China culture from some priests who went to China to preach. Before that, he should have learned about China culture from the influence of oriental fever caused by Kyle Poirot. French sinologist Joachim Bouvet (Bai Jin, 1662- 1732) introduced the Zhouyi and the gossip system to Leibniz.
In Leibniz's eyes, "Yin" and "Yang" are basically his binary China version. He once asserted: "Binary is the most perfect universal logic language in the world".
In Thuringia, Germany, the famous Schlossbibliothek zu Gotha still keeps a copy of Lai's manuscript entitled "1 and 0, the magical origin of all numbers".
In fact, it is completely out of context to say that Leibniz invented binary only after seeing Yin and Yang. On the contrary, the full text of the manuscript is: "1 and 0, the magical origin of all numbers." ..... This is an excellent example of creating secrets, because everything comes from God. 》。
