| HENRY CAVENDISH ( 1731 - 1810 ): |
| He invented the torsion balance to measure the Newtonion gravitational constant by a laboratory experiment, and thus weighed the earth. He also performed experiments on the composition of air and properties of hydrogen. the Cavendish laboratory of combridge University was set up in his honour in 1871. He found various results on electricity also. |
| CHARLES AUGUSTIN DE COULOMB ( 1736-1806 ): |
| He was French scientist. He discovered ' Coulomb's Law'. He also worked on inverse square law among like and unlike magnetic poles, friction, windmills, elasticity of metal and silk fibres. |
| KARL FRIEDRICH GAUSS ( 1777-1855 ): |
| He, along with Wilhelm Welser, built the first electric telegraph in 1833. He was a child prodigy and was gifted in mathematics, physics, engineering, astronomy and even land surveying. He gave his GAUSS'S LAW in electrostatics. |
| MICHAEL FARADAY ( 1791-1867): |
| He was the discoverer of electromagnetic induction, laws of electrolysis and basis and basic relations between light and magnetism. He was the originator of the idea of the electro-magnetic field and lines of force. |
| ANDRE MARIE AMPERE ( 1775-1836 ): |
| |
| He was a French physicist who founded & named the science of electrodynamics or electromagnetism. He formulated the law of magnetic force between electric currents, based on his own experments. |
| Dolton, JOhn ( 1766-1844 ): |
| He was an English physicist and chemist who developed the most fundamental atomic theory that marked the establishment of chemistry as a true science. He make important contributions to meteorology, diffusion of gases, thermal expansion of gasses and theory of colour blindness. |
| Advogadro, Amedeo ( 1776-1856 ): |
| He was an Italian physicist who first set forth the 'AVOGADRO'S HYPOTHESIS'. Also Avogadro's law is one of the basic concepts of chemistry. |
| Maxwell, James Clerk ( 1831-1879 ): |
| He was scottish physicist who explained & found connections between time-varying electric and magnetic fields and also proposed a set of equations for these ( Maxwell's equations for the electromagnetic field). He found quantitative theory of electromagnetic waves He contributed to colour vision, kinetic theory of gases, distribution of velocities among molecules in a gas and their mean free path. |
