A mathematician is an expert in the field of mathematics; a person who is highly skilled and knowledgeable. It is a science that deals with numbers and their interrelations, combinations and operations, data, measurements, quantity, structure, space and generalizations. The science is extensively used in the fields of finance, engineering, industries, robotics, astronomy, business, information technology, and various other fields. Mathematicians analyze data, study patterns and develop mathematical models that not only help to further human knowledge, but are also utilized for solving problems in various fields. These scientists work in the fields of pure and applied mathematics. In the pure form of this science, the researchers work through abstract problems with the sole motive of furthering human knowledge and contributing to theory formation. On the other hand, professionals working in the applied form formulate mathematical models for problem solving in real-world situations. But these two fields are overlapping—what starts out as a theoretical study may spawn some practical applications, while applied study of maths may sometimes contribute to its theoretical base. They need to be highly analytical and technologically savvy with excellent reasoning skills. Browse this section to explore about the life and works of various famous mathematicians from all over the world.
