Isaac Newton is considered by many to be one of the most influential people in human history. Born on January 4th 1643 (New Style calendar, December 25th 1642 on the Old Style) at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, Isaac Newton was involved in the fields of physics, math, astronomy, among other fields. Best known in the Physics community for his three laws of motion as well as his description of universal gravitation, he was also responsible for much during his life. Born three months after the death of his father, a farmer also named Isaac Newton, he was born prematurely. He was a small child and not expected to survive.

When Newton was three, his mother remarried and moved in with her new husband, Reverend Barnabus…show more content…

From 1670 to 1672, Newton lectured on optics. During this period he investigated the refraction of light. It was during this research that he discovered that colours are the result of objects interacting with already coloured light, as opposed to the object creating the light itself. This became known as Newton’s Theory of Colour. It is through this work that he was able to produce the first reflecting telescope, completed in late 1668.
In 1679, Newton returned to his work on celestial mechanics. This renewed interest was triggered by a brief exchange of letters in 1679-1680 with Robert Hooke (of Hooke’s Law). The appearance of a comet in the winter of 1680-1681 further encouraged Newton’s re-emerging interest in astronomy. Newton then determined that the elliptical form of planetary orbits would result from a centripetal force inversely proportional to the square of the radius vector, later known as Newton’s Law of Universal Gravitation.
On July 5th 1687, Newton first published Philosophiæ Naturalis Principia Mathematica (Latin for "Mathematical Principles of Natural Philosophy") a three book compilation with the encouragement and financial help of Edmond Halley. It was in this work that Newton stated the laws that he is best known for, and that were responsible for a significant leap forward in science, the three laws on motion, universal gravitation, and gravitas (weight, the effect later known as gravity) among many other things, such as the speed

Sir Isaac Newton, a physicist, an astronomer, mathematician, theologian, alchemist and philosopher; and excelling beyond our imagination. He was the greatest in every one of those fields.

Early life of Isaac Newton

Newton was born on 4th January (Christmas Day according to the then calendar) 1642 in England and he died on 31st March, 1727. He was a premature baby; and small enough to fit inside a quart sized cup; and whose chances of survival were dim.

Newton used to cover the walls of his room with his colorful drawings and would fly kites, with lamps attached to their bases. He had even crafted a water clock as a kid. He made a mouse tread on a treadmill so that it could produce power to move a small windmill.

Newton always liked to fidget and discover new things. He had once struck a needle in his eyeball and moved it around till he saw white and colored circles. He did recover from the injurious incident.

He never let his stuttering speech inhibit him from expressing his thoughts and discoveries.

Newton was miserable in studies. But after physically beating up a bully at school, he decided to outwit him in studies also.

Newton had tried farming but had failed miserably at it.

Achievements of Isaac Newton

  • “Philosophiæ Naturalis Principia Mathematica” was the famous book written by Newton, and which contained his notion of gravity and the three laws of motion. Newton had observed an apple falling from the tree; and had induced that there must be an outside force acting which pulls an object to the ground. His law of inertia states that an object will remain in rest unless moved by another force. His second law of acceleration states that a heavier object will require more force to move. And his third law states that for every action there is an equal and opposite reaction.
  • Newton’s 6 inch constructed telescope, allowed him to see Jupiter’s moons.
  • Newton had used a prism to show that sunlight contained all of the colors of the rainbow. He also showed how white light contained all the colors found in nature. He also displayed how light would reflect, retract and absorb against objects and thus create various colors.
  • Newton analyzed that the time it would take for a body to cool depended on the temperature difference between the surroundings and the object.
  • Newton had invented the pet door; where pets could enter and exit the house without disturbing anyone.
  • Newton’s studies on light and planetary motion paved way for the first visit to the Moon.
  • Newton had formulated the field of Calculus, in mathematics; which calculates the rate of how things change; like the speeding of a car.
  • Newton was a very religious person; and would spend hours in studying and writing about the Bible. He had formulated the famous mathematical formula to calculate the value of Pi.
  • Newton had been appointed as the Warden of the Mint; where he had successfully nabbed 28 fraudsters trying to counterfeit money.

Later Life and Death

  • He was knighted by the Queen and thus earned the title of Sir.
  • Newton had predicted that the world would end in 2060.
  • He was shy in the one year of Parliament duty, and only spoke once; and that to ask someone to close the window.
  • His dog Diamond, by mistake, had ruined 20 years of his research by igniting the laboratory.
  • Newton’s interest in alchemy (forming gold and silver) and experimenting with mercury; ultimately led to his death being a result of mercury poisoning.
