Alessandro Volta(1745-1827)

An Italian Physicist who was a pioneer in the development of electricity. He created the first electric battery in 1800. This battery gave the world its first continuous, reliable source of electric current, and led to all important discoveries of the use of electricity. The unit of measuring electromotive force (emf), Volt(v) is named after him. He also proposed the law that the air expands at a constant rate with increasing temperature. Albert Einstein

(1879-1955)

German mathematical physicist. Famous for the theory of relativity. Motion is relative and there fore, can be measured only in relation with something else. According to him, the only unchanging quantity is the speed of light. His work led on to the making of nuclear bomb. He established the relationship between mass and energy with the famous equation E=mc2 . He received the Nobel prize in 1921. Archimedes(287 BC-212 BC)

The ancient Greek mathematician who arrived at many important results in geometry, mechanics and hydrostatics. He defined the value of pi and obtained formula for curved surface areas and volumes of various solids. He is most famous for the principle of displacement named after him. George Boolie(1815-1864)

The self taught English mathematician who produced important works in many areas such as calculus and the theory of probability. He produced the methods of producing statements using a simple set of symbols. an interpretation of Boolean Algebra is the basis of digital processes in modern computers. Blaise Pascal(1623-1662)

A brilliant mathematician, physicist, religious thinker, and the founder of the modern theory of probability. He made mercury barometer and measured atmospheric pressure. The invention of mercury barometer paved the way for further studies in hydrostatics and hydrodynamics. He also invented the mechanical calculator, the syringe and created hydraulic press Rene Descartes(1596-1650)

A French philosopher and mathematician. He was the first major philosopher in the modern era to make a serious effort to defeat skepticism. His views about knowledge and certainty and those on the relationship between mind and body have been very influential over the last three centuries." I am thinking there fore I exist" (Latin -'Cogito ergo sum'- from the discourse on method). He revelolutionized geometry, algebra and mathematical notation, to reduce the physical sciences to mathematics. He represented algebraic equations as geometrical curves, helping to establish co-ordinate geometry. S.N Bose(1894-1974)

An Indian mathematician, with masters in mixed mathematics. With Saha, he derived the Saha-Bose equation of state for a non ideal gas in1918. In 1920, he derived Rydberg law in the old quantum, theory. He introduced Bose statistics to account for photon identity. He worked experimentally and theoretically on crystallography, fluorescence, thermoluminescense and on general relativity. C.R.Rao(1920-)

Indian mathematician and statistician. Born in 1920 in Andhra Pradesh. He took his doctorate degree from the university of Cambridge. From 1949 to 1964 he was the director of the Indian statistical institute (ISI). He was awarded the prestigious Sandhi swaroop bhatnagar award in 1963. He became the member of the royal society in 1967.He is the author of a number of research papers and books Pythagoras(580 BC-500 BC)

A Greek mathematician and philosopher. His aim was to explain all natural phenomena in terms of mathematics. He is best known fort his formula for the proportions of the sides of a right angled triangle. The fundamentals of modern mathematics are based on Pythagoras ideas. He also worked out the mathematics of the harmonics that form the basis of western music today. Sophie Germain(1766-1831)

A French mathematician. Her greatest achievement was her partial proof of Fermat's last theorem. She made important contributions in several areas of...
