6 Things You Should Know About Isaac Newton | Mental Floss
Isaac Newton was an English scientist and mathematician. He made major contributions in mathematics and physics (the study of the relationship between matter like the inside of a bowl) mirror through an eyepiece in the side of the tube. 6 Things You Should Know About Isaac Newton He also had a troubled relationship with Hannah, confessing in his journal that he had once threatened to burn the He liked that Olde Time Religion (Very Olde Time!). In the environment of Cromwell's Protectorate, Hooke became involved with the likes of Beyond simply dealing with the relationship between stress and strain in a However, he also had a powerful rival: Sir Isaac Newton.
The issue was quickly controlled, however, by an exchange of formal, excessively polite letters that fail to conceal the complete lack of warmth between the men. Although their objections were shallow, their contention that his experiments were mistaken lashed him into a fury.
The correspondence dragged on untilwhen a final shriek of rage from Newton, apparently accompanied by a complete nervous breakdown, was followed by silence. The death of his mother the following year completed his isolation.

For six years he withdrew from intellectual commerce except when others initiated a correspondence, which he always broke off as quickly as possible. Influence of the Hermetic tradition During his time of isolation, Newton was greatly influenced by the Hermetic tradition with which he had been familiar since his undergraduate days. Newton, always somewhat interested in alchemynow immersed himself in it, copying by hand treatise after treatise and collating them to interpret their arcane imagery.
Under the influence of the Hermetic tradition, his conception of nature underwent a decisive change. Until that time, Newton had been a mechanical philosopher in the standard 17th-century style, explaining natural phenomena by the motions of particles of matter. Thus, he held that the physical reality of light is a stream of tiny corpuscles diverted from its course by the presence of denser or rarer media.
He felt that the apparent attraction of tiny bits of paper to a piece of glass that has been rubbed with cloth results from an ethereal effluvium that streams out of the glass and carries the bits of paper back with it.
This mechanical philosophy denied the possibility of action at a distance; as with static electricityit explained apparent attractions away by means of invisible ethereal mechanisms.

AboutNewton abandoned the ether and its invisible mechanisms and began to ascribe the puzzling phenomena—chemical affinitiesthe generation of heat in chemical reactionssurface tension in fluids, capillary actionthe cohesion of bodies, and the like—to attractions and repulsions between particles of matter. More than 35 years later, in the second English edition of the Opticks, Newton accepted an ether again, although it was an ether that embodied the concept of action at a distance by positing a repulsion between its particles.
Newton, however, regarded them as a modification of the mechanical philosophy that rendered it subject to exact mathematical treatment. As he conceived of them, attractions were quantitatively defined, and they offered a bridge to unite the two basic themes of 17th-century science—the mechanical tradition, which had dealt primarily with verbal mechanical imagery, and the Pythagorean tradition, which insisted on the mathematical nature of reality.
The Principia Planetary motion Newton originally applied the idea of attractions and repulsions solely to the range of terrestrial phenomena mentioned in the preceding paragraph. But late innot long after he had embraced the concept, another application was suggested in a letter from Hooke, who was seeking to renew correspondence.
Hooke mentioned his analysis of planetary motion—in effect, the continuous diversion of a rectilinear motion by a central attraction. Newton bluntly refused to correspond but, nevertheless, went on to mention an experiment to demonstrate the rotation of Earth: He sketched the path of fall as part of a spiral ending at the centre of Earth.
He was mistaken in the charge. Moreover, unknown to him, Newton had so derived the relation more than 10 years earlier. Nevertheless, Newton later confessed that the correspondence with Hooke led him to demonstrate that an elliptical orbit entails an inverse square attraction to one focus—one of the two crucial propositions on which the law of universal gravitation would ultimately rest. In andNewton dealt only with orbital dynamics; he had not yet arrived at the concept of universal gravitation.

Already Newton was at work improving and expanding it. Significantly, De Motu did not state the law of universal gravitation. For that matter, even though it was a treatise on planetary dynamicsit did not contain any of the three Newtonian laws of motion.
Only when revising De Motu did Newton embrace the principle of inertia the first law and arrive at the second law of motion.
Isaac Newton’s Personal Life
The second law, the force lawproved to be a precise quantitative statement of the action of the forces between bodies that had become the central members of his system of nature. By quantifying the concept of force, the second law completed the exact quantitative mechanics that has been the paradigm of natural science ever since.
The quantitative mechanics of the Principia is not to be confused with the mechanical philosophy. The latter was a philosophy of nature that attempted to explain natural phenomena by means of imagined mechanisms among invisible particles of matter. The mechanics of the Principia was an exact quantitative description of the motions of visible bodies.
Newton was able to show that a similar relation holds between Earth and its Moon. The distance of the Moon is approximately 60 times the radius of Earth. Newton compared the distance by which the Moon, in its orbit of known size, is diverted from a tangential path in one second with the distance that a body at the surface of Earth falls from rest in one second.
The law of universal gravitationwhich he also confirmed from such further phenomena as the tides and the orbits of cometsstates that every particle of matter in the universe attracts every other particle with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centres. When the Royal Society received the completed manuscript of Book I inHooke raised the cry of plagiarisma charge that cannot be sustained in any meaningful sense.
Hooke would have been satisfied with a generous acknowledgment; it would have been a graceful gesture to a sick man already well into his decline, and it would have cost Newton nothing.
Newton, instead, went through his manuscript and eliminated nearly every reference to Hooke.

During this time, the legislative body enacted the Bill of Rights, which limited the power of the monarchy and laid out the rights of Parliament along with certain individual rights. Newton served a second brief term in Parliament, from toand again seems to have contributed little.
He had fierce rivalries. When it came to his intellectual rivals, Newton could be jealous and vindictive. Among those with whom he feuded was German mathematician and philosopher Gottfried Leibniz; the two men had a bitter battle over who invented calculus.
In the s, Leibniz formulated his own version of calculus, publishing his work a decade later. Newton later charged that the German scholar had plagiarized his unpublished writings after documents summarizing it circulated through the Royal Society.
It is not as if Hooke was unappreciated in his own time. His book, Micrographiawas a bestseller, inspiring interest in the use of microscopes.
He was a longtime president of the Royal Society, showing the regard in which his scientific work was held. However, he also had a powerful rival: The two clashed bitterly in attempts to forge reputations as the greatest scientific minds of their age.
In life this battle may have been a close run thing, but through history Newton became the undisputed winner.
Sir Isaac Newton
The first signs of conflict between these two massive egos came inwhen Newton submitted his first paper to the Royal Society. Correspondence between the two became increasingly acrimonious; a major rivalry had started.
This simmering tension exploded when Newton published his Principia incontaining his Law of Universal Gravitation.
