Albert EinsteinAlbert Einstein remains a mythical figure of our time, more even than they became in life, if one considers that its image in the poster condition and exhibiting an unusual gesture of derision, has been elevated to the dignity of domestic icon, along with the idols of the song and the stars of Hollywood.

However, there are his scientific genius and his human size that best explain it as myth, but perhaps the accumulation of paradoxes contained in his own biography, accented with historical perspective. When Einstein champion of pacifism is still remembered as the 'father of bomb', and still stream which it has the proof of principle that "everything is relative" to him, who fought bitterly against the possibility of knowing the actually meant to play with her blind man's buff.

Albert Einstein was born in the Bavarian city of Ulm on March 14, 1879. He was the eldest son of Hermann Einstein and Pauline Koch, both Jews whose families came from Swabia. The following year he moved to Munich, where the father was established, along with his brother Jakob, as merchant for engineers of the time.

Little Albert was a quiet and withdrawn child, who had a slow intellectual development. Einstein himself attributed to the slowness of the fact of being the only person to develop a theory of relativity as "a normal adult is not disturbed by the problems posed by space and time, considering that all there is to know about it already knows from his early childhood. I, on the contrary, I have had a development so slow that I started to ask myself questions about space and time until I was old.

Thomas Alva EdisonThomas Alva Edison(February 11, 1847 October 18, 1931) was anAmericaninventorandbusinessman. He developed many devices that greatly influenced life around the world, including thephonograph, themotion picture camera, and a long-lasting, practical electriclight bulb. Dubbed "The Wizard of Menlo Park",[3]he was one of the firstinventorsto apply the principles ofmass productionand large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrialresearch laboratory.[4]Edison was aprolific inventor, holding 1,093US patents in his name, as well as many patents in the United Kingdom, France, and Germany. More significant than the number of Edison's patents was the widespread impact of his inventions:electric lightand power utilities,sound recording, andmotion picturesall established major new industries world-wide. Edison's inventions contributed tomass communicationand, in particular, telecommunications. These included astock ticker, a mechanical vote recorder, a battery for an electric car, electrical power, recorded music andmotion pictures.His advanced work in these fields was an outgrowth of his early career as atelegraphoperator. Edison developed a system of electric-power generation and distribution [5]to homes, businesses, and factories a crucial development in the modern industrialized world. His firstpower stationwas on Pearl Street inManhattan, New York.[5]
