As a science, advanced mathematics has its inherent characteristics, namely, high abstraction, strict logic and wide application. Abstraction is the most basic and remarkable feature of mathematics. With a high degree of abstraction and unity, we can profoundly reveal its essential laws and make it more widely used.

Strict logic means that in the induction and arrangement of mathematical theory, whether it is concept and expression, or judgment and reasoning, we must use the rules of logic and follow the laws of thinking.

German mathematician Leibniz and British scientist Newton independently established calculus, Newton established relevant mathematical formulas around the law of universal gravitation, and Leibniz put forward Leibniz discriminant method in the convergence property of series.

Bernoulli, a Swiss scientist, put forward Bernoulli's principle that "the flow velocity increases and the pressure decreases" in his book Fluid Dynamics in 1738, and wrote an equation of fluid mechanics called Bernoulli equation.
