THE FATHERS OF PHYSICS
Albert Einstein was born at Ulm, in Württemberg, Germany, on March 14, 1879. Einstein always appeared to have a clear view of the problems of physics and the determination to solve them. He had a strategy of his own and was able to visualize the main stages on the way to his goal. After his retirement he continued to work towards the unification of the basic concepts of physics, taking the opposite approach, geometrisation, to the majority of physicists.
Isaac Newton was born on 4 January 1643 in Woolsthorpe, Lincolnshire. His father was a prosperous farmer, who died three months before Newton was born. In 1661, he went to Cambridge University where he became interested in mathematics, physics and astronomy. In October 1665, a plague epidemic forced the university to close and Newton returned to Woolsthorpe. He spent his years thinking about gravity, optics and worked on many researches in calculus as well.
Galileo Galilei was an Italian scientist who formulated the basic law of falling bodies, which he verified by careful measurements. He constructed a telescope with which he studied lunar craters, and discovered four moons revolving around Jupiter and espoused the Copernican cause.
Thomas Alva Edison is one of the greatest inventors in history and was responsible for more inventions than any other inventor. He created the first research laboratory, which he called The Invention Factory, probably one of his greatest achievements. Altogether he took out patents on 1093 inventions and is most renowned for inventing electricity, especially the light bulb.
