Isaac Newton- Essay for Students

Sir Isaac Newton was not only one of the greatest physicists ever, but he was also one of the scientists who contributed a lot to mathematics.  He made most of his mathematical contributions when he was the first student and professor at Trinity College, Cambridge, between 1661 and 1696.  Our world would not be the same today without the important discoveries of this farmer's son.

Sir Isaac Newton -Essay

 The years 1665-66 were one of the worst years for England when the Bubonic Plague devastated all the major cities.  1665 is also the year when Newton received his B.A.  When the school was closed to fight the plague, Newton moved back to Woolstorpe's family farm.  During those two years when he spent all his time in solitude apart from devoting himself to physics and mathematics, Newton discovered the law of gravity and made significant progress in mathematics.

 Here is a list of 23-year-old Newton's achievements during those two      critical years:

 He discovered the law of universal gravitation, invented calculus (at the same time independently of Leibniz in Germany), and further developed the binomial theorem, and began his lifelong study in optics and the theory of colors.

 There, while living on his farm for two years, Newton discovered and proved that the same force that pulls the rock towards the earth (i.e. gravity) is the same force that pulls the moon towards the earth and keeps it in orbit  .  He later developed it as the "principle of universal gravitation", stating that any two objects in the universe attracted each other in direct proportion to the product of their mass and inversely proportional to the square of the distance between them.

  Newton is known for his 3 laws of motion:

 Rule 1 (law of inertia): If an object is at rest and no pure force is acting on it, then it will remain at rest.  If it is moving at a constant speed and no pure force is acting on it, it will continue to move at the same steady speed.

 Law 2: F = The net force acting on an object, its mass is multiplied by the acceleration of the object. Thus if an object is moving with a steady motion, i.e. if its acceleration is zero, then zero net force acts on it.

Rule 3: Every action has the same and opposite reaction.  If A is pushing B with the force of F, B is also pushing A in the opposite direction with the force of F.  The sun attracts the earth, and the earth attracts the sun with the same force!

       During 1668 and 1669, Newton worked on optics at Cambridge University.1669 is another important year in Newton's life, since Prof. Isaac Barrow resigned from the famous "Lucasian Chair" in Cambridge and introduced Newton as its second inhabitant. With the protection of a good working position, Newton continued his study in the nature of light and optics with renewed vigor.

 Here is a summary of Newton's various contributions to the science of optics, some of which culminated in his 1704 book "Optics".

Newton developed devices for grinding lenses into shapes other than spheres.  He is the first person in human history to discover that, when passing through a prism, sunlight splits into a bundle of different colored rays. Based on that observation he developed the first successful interpretation of the rainbow.

The Great physicist has also discovered the Telescope which is still known by his name today;  Invented a reflector microscope in 1672, as well as discovered a sextant which J. in 1731.  Hadley had discovered independently.

 However, for all his daring discoveries in optics and the theory of colors, Newton was heavily attacked during the 1670s. Sometimes it takes a little less time than a talented person to catch the greatest discoveries in human history. Even if Newton had died in the mid-twenties, his place in the world of mathematics and science would have been quite secure.  But he lived almost 60 more years and he pushed the boundaries of human logic and science even further - thanks to his extraordinary gifts as a physicist and mathematician.

Sir Isaac Newton, arguably the greatest scientist ever, said that, in the absence of any other evidence, only the thumb would convince me of the existence of God.

Confirming another Newtonian quote, God created everything from numbers, weights and measurements, is numerology - the divine science of numbers in which numbers are only labels defining vibrational frequencies, numbers and frequencies that affect our lives and destiny. It is impossible to deny, condemn or reject the reality of such a vast and intelligent power through numerology which is beyond the scope of human understanding.
