SIR ISAAC NEWTON - An X-Mas Gift to Mankind
Sir Isaac Newton was an English Physicist, Mathematician, Astronomer, Natural Philosopher and theologian. He was born in Woolsthorpe, England on the X-mas day of 1642.Newton was born 3 months after the death of his father, a farmer also known as Isaac Newton. Junior Isaac was a premature baby. His mother went for a second marriage and left Newton in the care of his maternal grandmother.Newton had his basic education at The King's School, Grantham. In June 1661, he was admitted to Trinity College. In 1665, he discovered the general binomial theorem and then began to develop the mathematical theory that later became infinitesimal calculus. Newton obtained his degree in August 1665.
During middle years he worked on Mathematics. Later, Newton became involved in dispute with Leibniz over the priority in the development of infinitesimal calculus.Modern historians believe that Newton and Leibniz developed infinitesimal calculus independently although with very different notations.
OPTICS
From 1670 to 1672, Newton lectured on optics. During this period, he investigated on refraction of light, demonstrating that a prism could decompose white light into seven colors. In his hypothesis of light of 1675, Newton posited the existence of the ether to transmit forces between particles. John Maynard Keynes stated that " Newton was not the first of the age of reason: he was the last of the magicians".
Mechanics, Gravitation and the birth of Principia Mathematica.
In 1679, Newton returned to the study of celestial mechanics. That is, gravitation and its effect on the orbits of planets with reference to Kepler's law of planetary motions. The book Naturalis Prinicipia Mathematica was published in 5th July 1687.
Newton's Apple tree
It is a wonder that the content of this book still exists novel. With Principia, Newton became internationally recognized.
Later Life
In 1690s, Newton wrote a number of religious tracts dealing with the literal interpretation of The Bible. Newton was a member of the parliament of England. In April 1705, Queen Anne knighted Newton during the royal visit to Trinity College. Towards his end of life, Newton took up residence at Cranbury Park and continued there until his death in 1727. Newton died in his sleep in London on 31st March 1727 and buried in West Minster Abbey. After his death, Newton's body was discovered to have had massive amounts of mercury in it, probably resulting from his alchemical pursuits. Mercury poisoning could explain Newton's eccentricity in late life.
English poet Alexander Pope wrote the epitaph
"Nature and nature's laws lay hid in night;
God said,"Let Newton be" and all was light"

ARCHIMEDES OF SYRACUSE
Archimedes was born in 287 BC, in Syracuse and died in 212BC. His age was around 75 Yrs. He resided in Syracuse, SICILY. He worked in the fields of Mathematics, Physics, Engineering, Astronomy and Inventions. He is known for Archimedes Screw, Hydrostatics, Levers and infinitesimals. Archimedes was killed by Roman soldier during the siege of Syracuse.
Archimedes's mother's name is unknown but his father was Phidias who was an Astronomer. It is believed that Archimedes was a student of Euclid in Alexandria, Egypt before returning to his native place Syracuse. He proved that an object plunged in to liquid become lighter by an amount equal to the weight of the liquid it displaces. A famous story on this is that Archimedes made this discovery when he stepped into a bath tub, then celebrated by running through the streets shouting 'Eureka', which means"I have found it!". A machine invented by him for rising water is known as Archimedes's screw. History says that he developed numerous equipments to keep the Romans at bay for years during the siege of Syracuse.
Archimedes Quote
" Give me a lever, Long enough and a fulcrum on which to place it, and I shall move the Earth!"
