Isacc Newton
Toward the end of the 1600s Newton picked up on Descartes' theories of motion and completed the mechanistic vision of the universe that he had laid out.In his Principia (1687) he so thoroughly pulled the mechanistic vision together that it became the single most important foundation piece for the modern world-view.
He "demonstrated" that all things within the universe are made up of minute bits of matter which are held together in their shape and movement through the force of natural attraction or gravity (the gravitational attraction of two bodies is equal to the product of their mass divided by the square of the distance between them).This theory explained quite fully everything from the movement of the planets through the skies,to the movements of the tides,to the velocity of falling objects--and more.
Just as importantly--the completeness of the theory left no possibility of seeing creation as a "living" thing.Creation was without life of its own; it was instead mere "matter" responding mechanically to a set of fixed mathematical laws.
Nonetheless,Newton thought of himself as being religiously quite devout.His theory of the universe --so he thought--was intended as a powerful tribute to the Grand Architect who designed such a wonderfully complex yet beautiful creation.
However,Newton depicted God in such a way that God actually lost "personality" and the realm of sovereign action.God was left a role in nature largely as "First Mover" with no further significant intervention in life.God nearly became identified with the eternity or infinity of the universe.
Thomas Edison's Life
Thomas Alva Edison was born in 1847 in Milan,Ohio.At that time,James Polk was President and Abraham Lincoln was just contemplating running for the legislature.When Edison died in 1931,at the age of 84,Herbert Hoover was President and we were in the middle of the Great Depression.During his lifetime Edison saw the United States engaged in two major wars:the Civil War when he was a teenager,and World War I when he was an adult and appointed to assist the Secretary of the Navy.His inventions had a significant effect upon his times and permanently altered the way in which we live today.Can you imagine life without the electric light?The phonograph and all of its improvements?The motion picture?
At the age of 12,Edison began work as a "candy butcher" aboard the Grand Trunk Railroad's commuter line between Port Huron,Michigan,where we lived with his parents,and Detroit.He sold newspapers,fruit and candy to the passengers.The train left Port Huron about 7:00 in the morning and returned at 9:00 or 9:30 at night.The trip included a six hour layover in Detroit,during which time he claims to have read "the entire public library." He was an omnivorous reader and loved to experiment with chemicals and machinery.He constantly wanted to investigate how things worked and liked to see if he could make things better.On the train he was allowed a table in an empty baggage car on which to work.He even brought a broken printing press,repaired it and taught himself to print.He may have produced the first newspaper printed on a moving train.Edison began noticing a loss of hearing around this time,which increased throughout his life.
At that time,telegraph lines often ran parallel to the railroad tracks,and many of the station masters were telegraph operators.Edison was struck by the importance of telegraphy in communication.At home he rigged a makeshift telegraph line between his house and that of a friend so that they could send messages back and forth.Later he and his father would "read" the paper over the telegraph line.Soon he decided to become a real telegraph operator,and with the help of one of the station masters,he learned this skill.He became a telegrapher at the age of 15 and began working for Western Union in such places as Indianapolis,Cincinnati and Memphis.In 1866,at the age of 19,Thomas Edison came to Louisville as an employee of Western Union whose office was then located at the Southwest corner of Main and Second Street.After a brief excursion to New Orleans in August 1866,he returned to work in Louisville.He then found lodging in a shotgun duplex on East Washington Street.
Edison requested the night shift at work which allowed him plenty of time to spend at his two favorite pastimes -- reading and experimenting.However,it was the latter that eventually cost him his job.One night in 1867,he was working with a battery when he spilled sulphuric acid onto the floor.It ran between the floorboards and onto his boss' desk below.The next morning he was fired.
While this event marked the end of Thomas Edison's stay in Louisville.

Stephen Hawking was born ion the 300th anniversary of the Galileo's death.He has come to be though of as the greatest mind in physics since Albert Einstein.
Hawking grew up outside London.His father was a doctor,his mother was active in politics.He was not a smart schoolboy,but knew from early on that he would study science.He became good at mathematics and in 1958 he and some friends built a simple computer tha actually worked.In 1959 he won a scholarship to Oxford University.In 1962 he got his degree with honors and went to Cambridge University to get a PhD in astronmy.There he become interested in black holes.After receiving his PhD,he statyed at Cambridge,becoming known even in his middle 20s for his pioneering ideas.
In 1968 he studied in the Institute of Astronomy in Cambridge.He published the very technical book,Large Scale Structure of Space-Time and afterwards made a great discovery.It had always been thought that nothing could escape a balck hole.He continude working on the theory of the origin of the universe.
At the age of 32,he was named a fellow of the Royal Society;at the same year he received the Albret Einstien Award.Five years later,in 1979,he was appointed Top Professor of Mathematics at Cambridge,which was held by Sir Isaac Newton 300 years earlier.
In 1988 Hawking wrote A Brief History of Time,which became a best-seller.He wrote other popular articles and appeared in movies and television.He remains extremely busy,and his work hardly slowed by the disease that affects muscle cintrol,for which he uses a wheelchair and speaks though a speech computer.He said,"My goal is simple.It is complete understanding of the unverse,why it is as it is and why it exists at all."
