Isaac newton inventions

When you think about Isaac Newton, you probably think of the apocryphal story about an apple falling on his head, giving him the idea for the theory of But before we get into that, let's take a quick look at this great man's life. Isaac Newton led a very fruitful life Born in 1642, Sir Isaac Newton was raised by his grandmother until age 12. His mother pulled him He studied law at Trinity College, Cambridge, taking care of wealthier students' rooms to pay his bills. During his time at Cambridge, Newton wrote down his thoughts in a set of notes called "Quaestiones Quaedam Philosophicae." The notes show that Newton had already found the main ideas behind calculus, a new way of quantifying and studying the rate of change of a quantity over time. Along with German mathematician Gottfried Leibniz, Newton would develop the techniques of differentiation and integration, which remain fundamental to mathematics and science today. In 1665 Cambridge closed temporarily due to an outbreak of bubonic plague, and Newton returned home to Lincolnshire for two years. He continued his studies on his own, during which time he had his "brainstorm" regarding gravity and developed his three laws of motion. He described these years as "the prime of my age for invention." Newton returned to Cambridge in 1667 and was awarded the distinction of scholar, reserved for the highest-performing students. In 1670, he was appointed to the prestigious Lucasian Chair of Mathematics, aged just 27. He served as...

Isaac Newton (1642–1727) is best known for having invented the calculus in the mid to late 1660s (most of a decade before Leibniz did so independently, and ultimately more influentially) and for having formulated the theory of universal gravity — the latter in his Principia, the single most important work in the transformation of early modern natural philosophy into modern physical science. Yet he also made major discoveries in optics beginning in the mid-1660s and reaching across four decades; and during the course of his 60 years of intense intellectual activity he put no less effort into chemical and alchemical research and into theology and biblical studies than he put into mathematics and physics. He became a dominant figure in Britain almost immediately following publication of his Principia in 1687, with the consequence that “Newtonianism” of one form or another had become firmly rooted there within the first decade of the eighteenth century. His influence on the continent, however, was delayed by the strong opposition to his theory of gravity expressed by such leading figures as Christiaan Huygens and Leibniz, both of whom saw the theory as invoking an occult power of action at a distance in the absence of Newton's having proposed a contact mechanism by means of which forces of gravity could act. As the promise of the theory of gravity became increasingly substantiated, starting in the late 1730s but especially during the 1740s and 1750s, Newton became an equally d...

© duncan1890— DigitalVision Vectors/Getty ImagesNewton was the original developer of calculus, an advanced branch of mathematics that deals mostly with rates of change and with problems such as determining areas or volumes within curved lines or surfaces. Another mathematician, Gottfried Wilhelm Leibniz of Germany, who was a contemporary of Newton, independently developed the idea of calculus. It is now well established that Newton developedcalculusbefore Leibniz seriously pursued mathematics. However, it was Leibniz’s paper in 1684 that first made calculus a matter of public knowledge. Calculusis now the basic entry point for anyone wishing to study physics, chemistry, biology, economics, or finance.

He proposed that planetary orbits are mostly elliptical because of the Sun’s gravitation. In 1684 British astronomer De Motu (“On Motion”), which he then started to improve and expand. It grew into Philosophiae Naturalis Principia Mathematica ( The Mathematical Principles of Natural Philosophy), which is the fundamental work for the whole of modern science.

Sir Isaac Newton didn’t use his telescope to find any new things in the universe but he did use it to radically transform how we view the world we live in and the universe as a whole. Sir Isaac Newton is often considered as the greatest Astronomer and Mathematician to ever live. There is a lot of validity to this claim. This article looks at his famous reflector telescope and describes some of his discoveries. A reflector telescope is one that uses a mirror rather than lenses to bend light and magnify images. Reflector telescopes, because they are easier to make and can be made in sizes much larger than refractors, are an invention that changed astronomy and our understanding of the universe. The largest refractor telescope in the world is forty inches in diameter and reflector telescopes dwarf this in comparison. There are currently several reflector type scopes that are over four hundred inches in diameter. Why a reflector is better than a refractor If you are familiar with a prism or a rainbow you can understand why reflectors are superior to refractors. When light passes through glass the different bands (or colors) pass through at different angles and this causes aberrations or problems in the images. This is called chromatic aberration and it gives us distorted views of what we see through a lens. In the time of Newton glass making and lens making was very primitive and the problems of chromatic aberration were not yet overcome. Today we can make lenses that have alm...

Hulton Archive/ Newton didn't attempt to publish some of his early discoveries, such as his work on the shape of orbits. Modesty and controversy made him hesitant to share his theories. His claim that all of natural philosophy -- the forebear to the natural sciences -- could be explained through mathematics was both groundbreaking and highly controversial when introduced in 1670 [source: ­Eventually Newton's genius came to be widely known. His three laws of motion -- inertia, acceleration, and action and reaction -- remain a cornerstone of modern physics. His law of universal gravitation laid forth the theory that all particles in the universe exerted some In his student years, Newton performed experiments in optics examining the nature of Isaac Barrow, Newton's mentor, was instrumental in presenting one of Newton's major inventions to the scientific community. The refracting telescope commonly used during the period often couldn't produce clearly focused images. Newton replaced the mirrors of the refracting reflecting telescope, was one-twelfth the size of conventional refracting telescopes and had more powerful magnification powers. Barrow's presentation of it to the Royal Academy earned Newton membership. ­Newton also created calculus as a response to the insufficiencies in mathematics of the time. Originally called the fluxions or the "method of series and fluxions," calculus provided methods for solving complex problems about orbits, curves and other issues that class...
