Euclid's mathematical theory has extensive application value in modern science. His Elements of Geometry is one of the foundations of modern mathematics, which has a great influence on the future development of geometry, mathematics and science, and on the whole way of thinking of westerners.

In addition, many other achievements of Euclid also influenced modern science. For example, he invented Euclid algorithm, which is an algorithm to calculate the greatest common divisor of two integers and is widely used in computer science.
