Most modern historians believe that Newton and Leibniz independently developed calculus and created their own unique symbols for it.

According to people around Newton, Newton came up with his method several years earlier than Leibniz, but he hardly published anything before 1693, and didn't give his complete explanation until 1704. At the same time, Leibniz published a complete description of his method in 1684.

2. Riemann

It has made great contributions to partial differential equations and their applications in physics. Even for physics itself, such as heat, electromagnetic non-over-distance action and shock wave theory.

Riemann's work directly influenced the development of mathematics in the second half of19th century. Many outstanding mathematicians have re-demonstrated the theorem asserted by Riemann, and many branches of mathematics have made brilliant achievements under the influence of Riemann's thought.

3. Joseph Lagrange

Lagrange's academic career was mainly in the second half of18th century. When mathematics, physics and astronomy are natural science subjects. The mainstream of mathematics is mathematical analysis developed from calculus, centered on the European continent; The mainstream of physics is mechanics; The mainstream of astronomy is celestial mechanics.

The development of mathematical analysis has deepened mechanics and celestial mechanics, and the topics of mechanics and celestial mechanics have become the driving force for the development of mathematical analysis. At that time, the representatives of natural science made historic and significant contributions in these three disciplines. The following are comments on Lagrange's major contributions.

4. George Berkeley

/kloc-in the 0/7th century, calculus, a mathematical tool, came out, showing its extraordinary power and making many difficult problems simple. However, the establishment of calculus theory is not rigorous, and the understanding and application of the basic concept of infinitesimal is also confusing. So calculus has been opposed by some people since its birth, and Becquerel is one of them.

5. Cauchy

Cauchy's analysis courses and related textbooks in comprehensive engineering schools have had a great influence on mathematics. Since Newton and Leibniz invented calculus (infinitesimal analysis for short), the theoretical basis of this subject is vague. In order to further develop, we must establish a strict theory. Cauchy first successfully established the limit theory.
