Mathematicians work in fields of statistics, actuarial sciences, mathematical modeling, cryptography, computer science; for teaching at both school and college level and a research career in mathematics, statistics and bio-informatics. A strong background in mathematics is also necessary for research in many areas of computer science, social science, and engineering. Knowledge of maths is applied in all fields of work, from creating software systems to the field of investigation in areas like brain mapping, in lie-detector machines, fingerprinting, etc. Also in art, the application of maths has become important for preservation of historic sculptures, paintings and works of ancient artists.
After doing M Sc Applied Mathematics there are good opportunities in research in Govt organizations like DRDO etc.
Srinivasa Ramanujan was one of India's greatest mathematical geniuses. He made substantial contributions to the analytical theory of numbers and worked on elliptic functions, continued fractions, and infinite series.
Albert Einstein: Perhaps the most famous known scientist of all time. His theories on relativity were groundbreaking and are still used today.
Leonhard Euler: Well known for his contributions to mathematical vocabulary and notation. In particular, he is considered the founder of function notation.
