Pure Mathematics
The mathematician Bertrand Russell is reputed to have said: 'The pure mathematician, like the musician, is a free creator of his world of ordered beauty.' Pure mathematics is a study of math for its own sake; to find beautiful truths independently of applications. Yet in spite of that, pure math never can entirely avoid being useful. Areas of pure math include number theory, topology, real and complex analysis, graph theory, and algebra.
