##### Welcome! I am Dr. Rehena Nasrin working as an Associate Professor of
Department of Mathematics, Bangladesh University of Engineering and
Technology (BUET). I have completed my Honours and Masters degree from
Department of Mathematics, DU and M.Phil. and Ph. D. degree from Department of Mathematics, BUET.

#### MATHEMATICS

Mathematics is the mother of science. It
applies the principles of physics and natural sciences for analysis,
design, manufacturing and maintenance of systems. Mathematicians seek out
patterns and formulate new conjectures. Mathematicians resolve the truth
or falsity of conjectures by mathematical proof. Through the use of
abstraction and logical reasoning, mathematics developed from counting,
calculation, measurement, and the systematic study of the shapes and
motions of physical objects. Practical mathematics has been a human
activity for as far back as written records exists. Mathematics is used
throughout the world as an essential tool in many fields, including
natural science, engineering, medicine, and the social sciences. It is one
of the oldest and broadest disciplines. The mathematician may design a
component, a system or a process. Mathematics is used throughout the world
as an essential tool in many fields, including natural science,
engineering, medicine, and the social sciences.

Applied mathematics,
the branch of mathematics concerned with application of mathematical
knowledge to other fields, inspires and makes use of new mathematical
discoveries, which has led to the development of entirely new mathematical
disciplines, such as statistics and game theory. Mathematicians also
engage in pure mathematics, or mathematics for its own sake, without
having any application in mind. There is no clear line separating pure and
applied mathematics, and practical applications for what began as pure
mathematics are often discovered. Mathematicians will analyze their design
using the principles of motion, energy, and force to insure the prod
Mathematicians are needed in the environmental and bio-medical fields.
Indeed virtually every product or service in modern life has probably been
touched in some way by a mathematician.
