What did Newton come up with? In memory of the founder of classical mechanics

Sir Isaac Newton. Born December 25, 1642 - died March 20, 1727. English physicist, mathematician, mechanic and astronomer, one of the founders of classical physics. The author of the fundamental work “Mathematical Principles of Natural Philosophy,” in which he outlined the law of universal gravitation and the three laws of mechanics, which became the basis of classical mechanics. He developed differential and integral calculus, color theory, laid the foundations of modern physical optics, and created many other mathematical and physical theories.

Isaac Newton was born in the village of Woolsthorpe, Lincolnshire, on the eve of the Civil War. Newton's father, a small but successful farmer Isaac Newton (1606-1642), did not live to see the birth of his son.

The boy was born prematurely and was sickly, so they did not dare to baptize him for a long time. And yet he survived, was baptized (January 1), and named Isaac in memory of his father. Newton considered the fact of being born on Christmas a special sign of fate. Despite poor health in infancy, he lived to be 84 years old.

Newton sincerely believed that his family went back to the Scottish nobles of the 15th century, but historians discovered that in 1524 his ancestors were poor peasants. By the end of the 16th century, the family became rich and became yeomen (landowners). Newton's father left an inheritance of a large sum of 500 pounds sterling at that time and several hundred acres of fertile land occupied by fields and forests.

In January 1646, Newton's mother, Hannah Ayscough (1623-1679), remarried. She had three children with her new husband, a 63-year-old widower, and began to pay little attention to Isaac. The boy's patron was his maternal uncle, William Ayscough. As a child, Newton, according to contemporaries, was silent, withdrawn and isolated, loved to read and make technical toys: a sundial and water clock, a mill, etc. All his life he felt lonely.

His stepfather died in 1653, part of his inheritance went to Newton’s mother and was immediately registered by her in Isaac’s name. The mother returned home, but focused most of her attention on the three youngest children and the extensive household; Isaac was still left to his own devices.

In 1655, 12-year-old Newton was sent to study at a nearby school in Grantham, where he lived in the house of the pharmacist Clark. Soon the boy showed extraordinary abilities, but in 1659 his mother Anna returned him to the estate and tried to entrust part of the management of the household to her 16-year-old son. The attempt was not successful - Isaac preferred reading books, writing poetry, and especially designing various mechanisms to all other activities.

At this time, Stokes, Newton's school teacher, approached Anna and began to persuade her to continue the education of her unusually gifted son; This request was joined by Uncle William and Isaac's Grantham acquaintance (relative of the pharmacist Clark) Humphrey Babington, a member of Trinity College Cambridge. With their combined efforts, they eventually achieved their goal.

In 1661, Newton successfully graduated from school and went to continue his education at Cambridge University.

In June 1661, 18-year-old Newton arrived in Cambridge. According to the charter, he was given an examination of his knowledge of the Latin language, after which he was informed that he had been admitted to Trinity College (College of the Holy Trinity) of the University of Cambridge. More than 30 years of Newton’s life are associated with this educational institution.

The college, like the entire university, was going through a difficult time. The monarchy had just been restored in England (1660), King Charles II often delayed payments due to the university, and dismissed a significant part of the teaching staff appointed during the revolution. In total, 400 people lived at Trinity College, including students, servants and 20 beggars, to whom, according to the charter, the college was obliged to give alms. The educational process was in a deplorable state.

Newton was included in the category of "sizer" students (sizar), from whom tuition fees were not charged (probably on Babington's recommendation). According to the norms of that time, the sizer was obliged to pay for his education through various works at the University, or by providing services to wealthier students. Very little documentary evidence and memories of this period of his life have survived. During these years, Newton's character was finally formed - the desire to get to the bottom, intolerance to deception, slander and oppression, indifference to public fame. He still had no friends.

In April 1664, Newton, having passed the exams, moved to a higher student category of “scholars”, which gave him the right to a scholarship and continued education at college.

Despite Galileo's discoveries, science and philosophy were still taught in Cambridge. However, Newton's surviving notebooks already mention Cartesianism, Kepler and Gassendi's atomic theory. Judging by these notebooks, he continued to make (mainly scientific instruments), and was enthusiastically engaged in optics, astronomy, mathematics, phonetics, and music theory. According to the memoirs of his roommate, Newton devoted himself wholeheartedly to his studies, forgetting about food and sleep; probably, despite all the difficulties, this was exactly the way of life that he himself desired.

The year 1664 in Newton's life was rich in other events. Newton experienced a creative surge, began independent scientific activity and compiled a large-scale list (of 45 points) of unsolved problems in nature and human life (Questionnaire, lat. Questiones quaedam philosophicae). In the future, similar lists appear more than once in his workbooks. In March of the same year, lectures began at the college's newly founded (1663) mathematics department by a new teacher, 34-year-old Isaac Barrow, a major mathematician, Newton's future friend and teacher. Newton's interest in mathematics increased sharply. He made the first significant mathematical discovery: binomial expansion for an arbitrary rational exponent (including negative ones), and through it he came to his main mathematical method - the expansion of a function into an infinite series. At the very end of the year, Newton became a bachelor.

The scientific support and inspiration for Newton's work were the physicists: Galileo and Kepler. Newton completed their work by combining them into a universal system of the world. Other mathematicians and physicists had a lesser but significant influence: Fermat, Huygens, Wallis and his immediate teacher Barrow.

In Newton's student notebook there is a program phrase: “In philosophy there can be no sovereign except truth... We must erect gold monuments to Kepler, Galileo, Descartes and write on each one: “Plato is a friend, Aristotle is a friend, but the main friend is truth.”.

On Christmas Eve 1664, red crosses began to appear on London houses - the first marks of the Great Plague Epidemic. By summer, the deadly epidemic had expanded significantly. On 8 August 1665, classes at Trinity College were suspended and the staff disbanded until the end of the epidemic. Newton went home to Woolsthorpe, taking with him the main books, notebooks and instruments.

These were disastrous years for England - a devastating plague (a fifth of the population died in London alone), a devastating war with Holland, and the Great Fire of London. But Newton made a significant part of his scientific discoveries in the solitude of the “plague years.” From the surviving notes it is clear that the 23-year-old Newton was already fluent in the basic methods of differential and integral calculus, including series expansion of functions and what was later called the Newton-Leibniz formula. After conducting a series of ingenious optical experiments, he proved that white color is a mixture of the colors of the spectrum.

But his most significant discovery during these years was law of universal gravitation. Later, in 1686, Newton wrote to Halley: “In papers written more than 15 years ago (I cannot give the exact date, but, in any case, it was before the start of my correspondence with Oldenburg), I expressed the inverse quadratic proportionality of the gravitational force of the planets to the Sun depending on the distance and calculated the correct the relationship between the earth's gravity and the conatus recedendi [striving] of the Moon towards the center of the Earth, although not entirely accurate".

The inaccuracy mentioned by Newton was caused by the fact that Newton took the dimensions of the Earth and the magnitude of the acceleration of gravity from Galileo’s Mechanics, where they were given with a significant error. Later, Newton received more accurate data from Picard and was finally convinced of the truth of his theory.

Well known legend that Newton discovered the law of gravitation by observing an apple falling from a tree branch. For the first time, “Newton’s apple” was briefly mentioned by Newton’s biographer William Stukeley (the book “Memoirs of the Life of Newton”, 1752): “After lunch the weather was warm, we went out into the garden and drank tea in the shade of the apple trees. He [Newton] told me that the thought of gravity occurred to him while he was sitting under a tree in the same way. He was in a contemplative mood when suddenly an apple fell from a branch. “Why do apples always fall perpendicular to the ground?” - he thought."

The legend became popular thanks to Voltaire. In fact, as can be seen from Newton's workbooks, his theory of universal gravitation developed gradually.

Newton Isaac. Newton's apple of discord

Another biographer, Henry Pemberton, gives Newton's reasoning (without mentioning the apple) in more detail: "by comparing the periods of the several planets and their distances from the sun, he found that... this force must decrease in quadratic proportion as the distance increases." In other words, Newton discovered that from Kepler’s third law, which relates the orbital periods of planets to the distance to the Sun, it follows precisely the “inverse square formula” for the law of gravity (in the approximation of circular orbits). Newton wrote out the final formulation of the law of gravitation, which was included in textbooks, later, after the laws of mechanics became clear to him.

These discoveries, as well as many of the later ones, were published 20-40 years later than they were made. Newton did not pursue fame.

In 1670 he wrote to John Collins: “I see nothing desirable in fame, even if I were capable of earning it. This would perhaps increase the number of my acquaintances, but this is exactly what I try most to avoid.”

He did not publish his first scientific work (October 1666), which outlined the fundamentals of analysis; it was found only 300 years later.

In March-June 1666, Newton visited Cambridge. However, in the summer a new wave of plague forced him to go home again. Finally, early in 1667, the epidemic subsided, and Newton returned to Cambridge in April. On October 1 he was elected a fellow of Trinity College, and in 1668 he became a master. He was allocated a spacious separate room to live in, assigned a salary (2 pounds per year) and was given a group of students with whom he conscientiously studied standard academic subjects for several hours a week. However, neither then nor later did Newton become famous as a teacher; his lectures were poorly attended.

Having strengthened his position, Newton traveled to London, where shortly before, in 1660, the Royal Society of London was created - an authoritative organization of prominent scientific figures, one of the first Academies of Sciences. The publication of the Royal Society was the journal Philosophical Transactions.

In 1669, mathematical works using expansions in infinite series began to appear in Europe. Although the depth of these discoveries could not be compared with Newton's, Barrow insisted that his student fix his priority in this matter. Newton wrote a brief but fairly complete summary of this part of his discoveries, which he called "Analysis using equations with an infinite number of terms". Barrow sent this treatise to London. Newton asked Barrow not to reveal the name of the author of the work (but he still let it slip). “Analysis” spread among specialists and gained some fame in England and abroad.

In the same year, Barrow accepted the king's invitation to become a court chaplain and left teaching. On 29 October 1669, the 26-year-old Newton was elected as his successor, professor of mathematics and optics at Trinity College, with a high salary of £100 per annum. Barrow left Newton an extensive alchemical laboratory; During this period, Newton became seriously interested in alchemy and conducted a lot of chemical experiments.

At the same time, Newton continued experiments in optics and color theory. Newton studied spherical and chromatic aberration. To reduce them to a minimum, he built a mixed reflecting telescope: a lens and a concave spherical mirror, which he made and polished himself. The project of such a telescope was first proposed by James Gregory (1663), but this plan was never realized. Newton's first design (1668) was unsuccessful, but the next one, with a more carefully polished mirror, despite its small size, provided a 40-fold magnification of excellent quality.

Rumors about the new instrument quickly reached London, and Newton was invited to show his invention to the scientific community.

At the end of 1671 - beginning of 1672, a demonstration of the reflector took place before the king, and then at the Royal Society. The device received universal rave reviews. The practical importance of the invention probably also played a role: astronomical observations served to accurately determine time, which in turn was necessary for navigation at sea. Newton became famous and in January 1672 was elected a member of the Royal Society. Later, improved reflectors became the main tools of astronomers, with their help the planet Uranus, other galaxies, and red shift were discovered.

At first, Newton valued his communication with colleagues from the Royal Society, which included, in addition to Barrow, James Gregory, John Wallis, Robert Hooke, Robert Boyle, Christopher Wren and other famous figures of English science. However, tedious conflicts soon began, which Newton really did not like. In particular, a noisy controversy erupted over the nature of light. It began when, in February 1672, Newton published a detailed description of his classical experiments with prisms and his theory of color in the Philosophical Transactions. Hooke, who had previously published his own theory, stated that he was not convinced by Newton's results; he was supported by Huygens on the grounds that Newton's theory "contradicts generally accepted views." Newton responded to their criticism only six months later, but by this time the number of critics had increased significantly.

An avalanche of incompetent attacks left Newton irritated and depressed. Newton asked the secretary of the Oldenburg Society not to send him any more critical letters and made a vow for the future: not to get involved in scientific disputes. In his letters, he complains that he is faced with a choice: either not to publish his discoveries, or to spend all his time and energy repelling unfriendly amateur criticism. In the end he chose the first option and announced his resignation from the Royal Society (8 March 1673). It was not without difficulty that Oldenburg persuaded him to stay, but scientific contacts with the Society were kept to a minimum for a long time.

Two important events occurred in 1673. First: by royal decree, Newton's old friend and patron, Isaac Barrow, returned to Trinity, now as the head ("master") of the college. Second: Newton, known at that time as a philosopher and inventor, became interested in Newton’s mathematical discoveries.

Having received Newton's 1669 work on infinite series and studied it deeply, he then independently began to develop his own version of analysis. In 1676, Newton and Leibniz exchanged letters in which Newton explained a number of his methods, answered Leibniz's questions, and hinted at the existence of even more general methods, not yet published (meaning general differential and integral calculus). The Secretary of the Royal Society, Henry Oldenburg, persistently asked Newton to publish his mathematical discoveries on analysis for the glory of England, but Newton replied that he had been working on another topic for five years and did not want to be distracted. Newton did not respond to Leibniz's next letter. The first brief publication on Newton's version of analysis appeared only in 1693, when Leibniz's version had already spread widely throughout Europe.

The end of the 1670s was sad for Newton. In May 1677, 47-year-old Barrow died unexpectedly. In the winter of the same year, a strong fire broke out in Newton's house, and part of Newton's manuscript archive burned down. In September 1677, the secretary of the Royal Society, Oldenburg, who favored Newton, died, and Hooke, who was hostile to Newton, became the new secretary. In 1679, mother Anna became seriously ill; Newton, leaving all his affairs, came to her, took an active part in caring for the patient, but the mother’s condition quickly deteriorated, and she died. Mother and Barrow were among the few people who brightened up Newton's loneliness.

In 1689, after the overthrow of King James II, Newton was first elected to Parliament from Cambridge University and sat there for little more than a year. The second election took place in 1701-1702. There is a popular anecdote that Newton took the floor to speak in the House of Commons only once, asking that the window be closed to avoid a draft. In fact, Newton carried out his parliamentary duties with the same conscientiousness with which he treated all his affairs.

Around 1691, Newton became seriously ill (most likely, he was poisoned during chemical experiments, although there are other versions - overwork, shock after a fire, which led to the loss of important results, and age-related ailments). Those close to him feared for his sanity; the few surviving letters of his from this period do indicate mental disorder. Only at the end of 1693 did Newton's health fully recover.

In 1679, Newton met at Trinity an 18-year-old aristocrat, a lover of science and alchemy, Charles Montagu (1661-1715). Newton probably made a strong impression on Montagu, because in 1696, having become Lord Halifax, President of the Royal Society and Chancellor of the Exchequer (that is, the Minister of the Exchequer of England), Montagu proposed to the king appoint Newton as superintendent of the Mint. The king gave his consent, and in 1696 Newton took this position, left Cambridge and moved to London. From 1699 he became the manager (“master”) of the Mint.

To begin with, Newton thoroughly studied the technology of coin production, put the paperwork in order, and redid the accounting over the past 30 years. At the same time, Newton energetically and skillfully contributed to Montagu's monetary reform, restoring confidence in the English monetary system, which had been thoroughly neglected by his predecessors.

In England during these years, almost exclusively inferior coins were in circulation, and in considerable quantities counterfeit coins were in circulation. Trimming the edges of silver coins became widespread. Now the coins began to be produced on special machines and there was an inscription along the rim, so that criminal grinding of the metal became almost impossible.

Over the course of 2 years, the old, inferior silver coin was completely withdrawn from circulation and re-minted, the production of new coins increased to keep up with the need for them, and their quality improved. Previously, during such reforms, the population had to change old money by weight, after which the volume of cash decreased both among individuals (private and legal) and throughout the country, but interest and loan obligations remained the same, which is why the economy began stagnation. Newton proposed exchanging money at par, which prevented these problems, and the inevitable shortage of funds after this was made up for by taking loans from other countries (most of all from the Netherlands), inflation dropped sharply, but the external public debt grew by the middle of the century to levels unprecedented in the history of England sizes. But during this time, noticeable economic growth occurred, because of it, tax contributions to the treasury increased (equal in size to those of France, despite the fact that France was inhabited by 2.5 times more people), due to this, the national debt was gradually paid off.

However, an honest and competent person at the head of the Mint did not suit everyone. From the very first days, complaints and denunciations rained down on Newton, and inspection commissions constantly appeared. As it turned out, many denunciations came from counterfeiters, irritated by Newton's reforms.

Newton, as a rule, was indifferent to slander, but never forgave if it affected his honor and reputation. He was personally involved in dozens of investigations, and more than 100 counterfeiters were tracked down and convicted; in the absence of aggravating circumstances, they were most often sent to the North American colonies, but several leaders were executed. The number of counterfeit coins in England has decreased significantly. Montagu, in his memoirs, highly appreciated the extraordinary administrative abilities shown by Newton and ensured the success of the reform. Thus, the reforms carried out by the scientist not only prevented an economic crisis, but also, decades later, led to a significant increase in the country’s well-being.

In April 1698, the Russian Tsar Peter I visited the Mint three times during the “Great Embassy”. Unfortunately, the details of his visit and communication with Newton have not been preserved. It is known, however, that in 1700 a monetary reform similar to the English one was carried out in Russia. And in 1713, Newton sent the first six printed copies of the 2nd edition of the Principia to Tsar Peter in Russia.

Newton's scientific triumph was symbolized by two events in 1699: the teaching of Newton's world system began at Cambridge (from 1704 at Oxford), and the Paris Academy of Sciences, the stronghold of his Cartesian opponents, elected him as a foreign member. All this time Newton was still listed as a member and professor of Trinity College, but in December 1701 he officially resigned from all his posts at Cambridge.

In 1703, the President of the Royal Society, Lord John Somers, died, having attended the meetings of the Society only twice during the 5 years of his presidency. In November, Newton was elected as his successor and ruled the Society for the rest of his life - more than twenty years.

Unlike his predecessors, he was personally present at all meetings and did everything to ensure that the British Royal Society took an honorable place in the scientific world. The number of members of the Society grew (among them, in addition to Halley, one can highlight Denis Papin, Abraham de Moivre, Roger Coates, Brooke Taylor), interesting experiments were carried out and discussed, the quality of journal articles improved significantly, financial problems were mitigated. The society acquired paid secretaries and its own residence (on Fleet Street); Newton paid the moving expenses out of his own pocket. During these years, Newton was often invited as a consultant to various government commissions, and Princess Caroline, the future Queen of Great Britain, spent hours talking with him in the palace on philosophical and religious topics.

In 1704, the monograph “Optics” was published (first in English), which determined the development of this science until the beginning of the 19th century. It contained an appendix “On the quadrature of curves” - the first and fairly complete presentation of Newton’s version of mathematical analysis. In fact, this is Newton's last work on the natural sciences, although he lived for more than 20 years. The catalog of the library he left behind contained books mainly on history and theology, and it was to these pursuits that Newton devoted the rest of his life.

Newton remained the manager of the Mint, since this post, unlike the position of superintendent, did not require much activity from him. Twice a week he went to the Mint, once a week to a meeting of the Royal Society. Newton never traveled outside of England.

Newton - a dark heretic

In 1705, Queen Anne knighted Newton. From now on he is Sir Isaac Newton. For the first time in English history, the title of knight was awarded for scientific merit; the next time it happened was more than a century later (1819, in reference to Humphry Davy). However, some biographers believe that the queen was guided not by scientific, but by political motives. Newton acquired his own coat of arms and a not very reliable pedigree.

In 1707, a collection of Newton's lectures on algebra, called “Universal Arithmetic,” was published. The numerical methods presented in it marked the birth of a new promising discipline - numerical analysis.

In 1708, an open priority dispute with Leibniz began, in which even the reigning persons were involved. This quarrel between two geniuses cost science dearly - the English mathematical school soon reduced activity for a whole century, and the European school ignored many of Newton’s outstanding ideas, rediscovering them much later. Even Leibniz's death did not extinguish the conflict.

The first edition of Newton's Principia has long been sold out. Newton's many years of work to prepare the 2nd edition, revised and expanded, was crowned with success in 1710, when the first volume of the new edition was published (the last, third - in 1713).

The initial circulation (700 copies) turned out to be clearly insufficient; there were additional printings in 1714 and 1723. When finalizing the second volume, Newton, as an exception, had to return to physics to explain the discrepancy between theory and experimental data, and he immediately made a major discovery - hydrodynamic compression of the jet. The theory now agreed well with experiment. Newton added an Instruction to the end of the book with a scathing critique of the “vortex theory” with which his Cartesian opponents tried to explain the motion of the planets. To the natural question “how is it really?” the book follows the famous and honest answer: “I still have not been able to deduce the cause... of the properties of the force of gravity from phenomena, and I do not invent hypotheses.”

In April 1714, Newton summarized his experience of financial regulation and submitted his article “Observations Concerning the Value of Gold and Silver” to the Treasury. The article contained specific proposals for adjusting the cost of precious metals. These proposals were partially accepted, and this had a beneficial effect on the British economy.

Shortly before his death, Newton became one of the victims of a financial scam by a large trading company, the South Sea Company, which was supported by the government. He purchased the company's securities for a large sum, and also insisted on their acquisition by the Royal Society. On September 24, 1720, the company bank declared itself bankrupt. Niece Catherine recalled in her notes that Newton lost more than 20,000 pounds, after which he declared that he could calculate the movement of celestial bodies, but not the degree of madness of the crowd. However, many biographers believe that Catherine did not mean a real loss, but a failure to receive the expected profit. After the company's bankruptcy, Newton offered to compensate the Royal Society for the losses from his own pocket, but his offer was rejected.

Newton devoted the last years of his life to writing the Chronology of Ancient Kingdoms, which he worked on for about 40 years, as well as preparing the third edition of the Principia, which was published in 1726. Unlike the second, the changes in the third edition were minor - mainly the results of new astronomical observations, including a fairly comprehensive guide to comets observed since the 14th century. Among others, the calculated orbit of Halley's comet was presented, the reappearance of which at the indicated time (1758) clearly confirmed the theoretical calculations of the (by then deceased) Newton and Halley. The circulation of the book for a scientific publication of those years could be considered huge: 1250 copies.

In 1725, Newton's health began to deteriorate noticeably, and he moved to Kensington near London, where he died at night, in his sleep, on March 20 (31), 1727. He did not leave a written will, but shortly before his death he transferred a significant part of his large fortune to his closest relatives. Buried in Westminster Abbey.

Legends and myths about Newton:

Several common legends have already been cited above: “Newton’s apple,” his only parliamentary speech.

There is a legend that Newton made two holes in his door - one larger, the other smaller, so that his two cats, large and small, could enter the house on their own. In fact, Newton never owned cats or other pets.

Another myth accuses Newton of destroying the only portrait of Hooke, once kept in the Royal Society. In reality, there is not a single piece of evidence to support such an accusation. Allan Chapman, Hooke's biographer, argues that no portrait of Hooke existed at all (which is not surprising, given the high cost of portraits and Hooke's constant financial difficulties). The only source of assumption about the existence of such a portrait is the mention of the German scientist Zechariah von Uffenbach, who visited the Royal Society in 1710, about the portrait of a certain “Hoock”, but Uffenbach did not speak English and, most likely, had in mind the portrait of another member of the society, Theodor Haack (Theodore Haak). Haack's portrait actually existed and has survived to this day. Further support for the view that there never was a portrait of Hooke is the fact that Hooke's friend and Secretary of the Society Richard Waller published a posthumous collection of Hooke's works in 1705 with excellent quality illustrations and a detailed biography, but without a portrait of Hooke; all other works of Hooke also do not contain a portrait of the scientist.

Newton is credited with an interest in astrology. If there was one, it quickly gave way to disappointment.

From the fact of Newton's unexpected appointment as governor of the Mint, some biographers conclude that Newton was a member of the Masonic lodge or other secret society. However, no documentary evidence in favor of this hypothesis has been found.

Isaac Newton was born on January 4, 1642 in Woolsthorpe, England. The boy was born in a small village into the family of a small farmer who died three months before the birth of his son. The boy was born prematurely and turned out to be sickly, so they did not dare to baptize him for a long time. And yet he survived, was baptized, and was named Isaac in memory of his father. Newton considered the fact of being born on Christmas a special sign of fate. Despite poor health in infancy, he lived eighty-four years.

When the child was three years old, his mother remarried and left, leaving him in the care of his grandmother. Newton grew up unsociable and prone to daydreaming. He was attracted to poetry and painting. Away from his peers, he made paper kites, invented a windmill, a water clock, and a pedal carriage.

Interest in technology forced Newton to think about natural phenomena and study mathematics in depth. After serious preparation, Isaac Newton entered Cambridge in 1660 as a Subsizzfr, the so-called poor students who were obliged to serve members of the college, which could not but burden Newton.

In six years, Isaac Newton completed all the college degrees and prepared all his further great discoveries. In 1665, Newton became a Master of Arts. In the same year, when the plague epidemic was raging in England, he decided to temporarily settle in Woolsthorpe.

It was there that the scientist began to actively study optics; the search for ways to eliminate chromatic aberration in lens telescopes led Newton to research into what is now called dispersion, that is, the dependence of the refractive index on frequency. Many of the experiments he conducted, and there are more than a thousand of them, have become classics and are repeated to this day in schools and institutes.

The leitmotif of all research was the desire to understand the physical nature of light. At first, Newton was inclined to think that light was a wave in the all-pervading ether, but later abandoned this idea, deciding that the resistance from the ether should noticeably slow down the movement of celestial bodies. These arguments led Newton to the idea that light is a stream of special particles, corpuscles, emitted from a source and moving in a straight line until they encounter obstacles.

The corpuscular model explained not only the straightness of the propagation of light, but also the law of reflection. This assumption was that light corpuscles, approaching the surface of water, for example, should be attracted by it and therefore experience acceleration. According to this theory, the speed of light in water should be greater than in air, which conflicted with later experimental data.

The formation of corpuscular ideas about light was clearly influenced by the fact that at that time the work that was destined to become the main great result of Newton’s work had already been largely completed: the creation of a unified physical picture of the World based on the laws of mechanics formulated by him.

This picture was based on the idea of material points, physically infinitesimal particles of matter and the laws governing their movement. It was the clear formulation of these laws that gave Newtonian mechanics completeness. The first of these laws was, in fact, the definition of inertial reference systems: it is in such systems that material points that do not experience any influences move uniformly and rectilinearly.

The second law of mechanics plays a central role. It states that the change in quantity, motion of the product of mass and speed per unit time is equal to the force acting on a material point. The mass of each of these points is a constant value. In general, all these points “do not wear out,” as Newton put it, each of them is eternal, that is, it can neither arise nor be destroyed. Material points interact, and the quantitative measure of the impact on each of them is force. The problem of figuring out what these forces are is the root problem of mechanics.

Finally, the third law, the law of “equality of action and reaction,” explained why the total momentum of any body that does not experience external influences remains unchanged, no matter how its constituent parts interact with each other.

Having posed the problem of studying various forces, Isaac Newton himself gave the first brilliant example of its solution, formulating the law of universal gravitation: the force of gravitational attraction between bodies whose dimensions are significantly less than the distance between them is directly proportional to their masses, inversely proportional to the square of the distance between them and directed along connecting them with a straight line. The law of universal gravitation allowed Newton to give a quantitative explanation of the movement of the planets around the Sun and the Moon around the Earth, and to understand the nature of sea tides.

This could not fail to make a huge impression on the minds of researchers. The program for a unified mechanical description of all natural phenomena: both “earthly” and “heavenly” was established in physics for many years. Moreover, for many physicists over the course of two centuries, the very question of the limits of applicability of Newton's laws seemed unjustified.

In 1668, Isaac Newton returned to Cambridge and soon received the Lucasian Chair of Mathematics. This chair was previously occupied by his teacher Isaac Barrow, who gave the chair to his favorite student in order to provide for him financially. By that time, Newton was already the author of the binomial and the creator of the fluxion method, what is now called differential and integral calculus.

In general, this period became the most fruitful in Newton’s work: in seven years, from 1660 to 1667, his main ideas were formed, including the idea of the law of universal gravitation. Not limiting himself to theoretical research alone, Isaac Newton in the same years designed and began to create a reflecting telescope.

This work led to the discovery of what were later called interference "lines of equal thickness". Newton, realizing that the “quenching of light by light” was manifested here, which did not fit into the corpuscular model, tried to overcome the difficulties that arose here by introducing the assumption that corpuscles in light move in waves, “tides.”

The second of the telescopes produced served as the occasion for Newton's presentation as a member of the Royal Society of London. When a scientist refused membership, citing a lack of funds to pay membership fees, it was considered possible, given his scientific merits, to make an exception for him, exempting him from paying them.

Being a very cautious person by nature, Isaac Newton, against his will, sometimes found himself drawn into discussions and conflicts that were painful for him. Thus, his theory of light and colors, outlined in 1675, caused such attacks that Newton decided not to publish anything on optics while Hooke, his most bitter opponent, was alive.

Newton also had to take part in political events. From 1688 to 1694, the scientist was a member of parliament. By that time, his main work, “Mathematical Principles of Natural Philosophy,” was published, the basis of the mechanics of all physical phenomena, from the movement of celestial bodies to the propagation of sound. For several centuries to come, this program determined the development of physics, and its significance has not been exhausted to this day.

Constant enormous nervous and mental stress led to the fact that in 1692 Newton fell ill with a mental disorder. The immediate impetus for this was a fire in which all the manuscripts he prepared were lost.

The constant oppressive feeling of material insecurity was undoubtedly one of the reasons for Newton’s illness. Therefore, the position of Warden of the Mint, while retaining his professorship at Cambridge, was of great importance to him. Zealously starting work and quickly achieving noticeable success, in 1699 he was appointed director. It remained impossible to combine this with teaching, and Newton moved to London.

At the end of 1703, Isaac Newton was elected president of the Royal Society. By that time, Newton had reached the pinnacle of fame. In 1705, he was elevated to knighthood, but, having a large apartment, six servants and a wealthy family, the scientist remains lonely. The time of active creativity is over, and Newton limits himself to preparing the edition of “Optics”, the republication of “Principles” and the interpretation of “Holy Scripture”. He owns the interpretation of the Apocalypse, an essay about the prophet Daniel.

Isaac Newton died on March 31, 1727 at his home in London. Buried in Westminster Abbey. The inscription on his grave ends with the words: “Let mortals rejoice that such an adornment of the human race lived in their midst.” Every year, on the birthday of the great Englishman, the scientific community celebrates Newton Day.

Isaac Newton was born on January 4, 1643 in the small British village of Woolsthorpe, located in the county of Lincolnshire. A frail boy who left his mother's womb prematurely came into this world on the eve of the English Civil War, shortly after the death of his father and shortly before the celebration of Christmas.

The child was so weak that for a long time he was not even baptized. But still, little Isaac Newton, named after his father, survived and lived a very long life for the seventeenth century - 84 years.

The father of the future brilliant scientist was a small farmer, but quite successful and wealthy. After the death of Newton Sr., his family received several hundred acres of fields and woodland with fertile soil and an impressive sum of 500 pounds sterling.

Isaac's mother, Anna Ayscough, soon remarried and bore her new husband three children. Anna paid more attention to her younger offspring, and Isaac’s grandmother, and then his uncle William Ayscough, was initially involved in raising her first-born.

As a child, Newton was interested in painting and poetry, selflessly inventing a water clock, a windmill, and making paper kites. At the same time, he was still very sickly, and also extremely unsociable: Isaac preferred his own hobbies to fun games with his peers.

Physicist in his youth

When the child was sent to school, his physical weakness and poor communication skills once even caused the boy to be beaten until he fainted. Newton could not endure this humiliation. But, of course, he could not acquire an athletic physical form overnight, so the boy decided to please his self-esteem in a different way.

If before this incident he studied rather poorly and was clearly not the teachers’ favorite, then after that he began to seriously stand out in terms of academic performance among his classmates. Gradually, he became a better student, and also became even more seriously interested in technology, mathematics and amazing, inexplicable natural phenomena than before.

When Isaac turned 16, his mother took him back to the estate and tried to entrust some of the responsibilities of running the household to the older eldest son (Anna Ayscough’s second husband had also died by that time). However, the guy did nothing but construct ingenious mechanisms, “swallow” numerous books and write poetry.

The young man's school teacher, Mr. Stokes, as well as his uncle William Ayscough and his acquaintance Humphrey Babington (part-time member of Trinity College Cambridge) from Grantham, where the future world-famous scientist attended school, persuaded Anna Ayscough to allow her gifted son to continue his studies. As a result of collective persuasion, Isaac completed his studies at school in 1661, after which he successfully passed the entrance exams to Cambridge University.

Beginning of a scientific career

As a student, Newton had the status of "sizar". This meant that he did not pay for his education, but had to perform various tasks at the university, or provide services to wealthier students. Isaac bravely withstood this test, although he still extremely disliked feeling oppressed, was unsociable and did not know how to make friends.

At that time, philosophy and natural science were taught in the world-famous Cambridge, although at that time the world had already been shown the discoveries of Galileo, the atomic theory of Gassendi, the bold works of Copernicus, Kepler and other outstanding scientists. Isaac Newton greedily absorbed all the possible information on mathematics, astronomy, optics, phonetics and even music theory that he could find. At the same time, he often forgot about food and sleep.

Isaac Newton studies the refraction of light

The researcher began his independent scientific activity in 1664, compiling a list of 45 problems in human life and nature that had not yet been solved. At the same time, fate brought the student together with the gifted mathematician Isaac Barrow, who began working in the college’s mathematics department. Subsequently, Barrow became his teacher, as well as one of his few friends.

Having become even more interested in mathematics thanks to a gifted teacher, Newton performed the binomial expansion for an arbitrary rational exponent, which became his first brilliant discovery in the mathematical field. That same year, Isaac received his bachelor's degree.

In 1665-1667, when the plague, the Great Fire of London and the extremely costly war with Holland swept through England, Newton settled briefly in Woesthorpe. During these years, he directed his main activity towards the discovery of optical secrets. Trying to figure out how to rid lens telescopes of chromatic aberration, the scientist came to the study of dispersion. The essence of the experiments that Isaac carried out was in an effort to understand the physical nature of light, and many of them are still carried out in educational institutions.

As a result, Newton came to a corpuscular model of light, deciding that it can be considered as a stream of particles that fly out from a certain light source and carry out linear motion to the nearest obstacle. Although such a model cannot lay claim to ultimate objectivity, it nevertheless became one of the foundations of classical physics, without which more modern ideas about physical phenomena would not have appeared.

Among those who like to collect interesting facts, there has long been a misconception that Newton discovered this key law of classical mechanics after an apple fell on his head. In fact, Isaac systematically walked towards his discovery, which is clear from his numerous notes. The legend of the apple was popularized by the then authoritative philosopher Voltaire.

Scientific fame

At the end of the 1660s, Isaac Newton returned to Cambridge, where he received master's status, his own room to live, and even a group of young students for whom the scientist became a teacher. However, teaching was clearly not the gifted researcher’s forte, and attendance at his lectures was noticeably poor. At the same time, the scientist invented a reflecting telescope, which made him famous and allowed Newton to join the Royal Society of London. Many amazing astronomical discoveries have been made through this device.

In 1687, Newton published perhaps his most important work, a work entitled “Mathematical Principles of Natural Philosophy.” The researcher had published his works before, but this one was of paramount importance: it became the basis of rational mechanics and all mathematical natural sciences. It contained the well-known law of universal gravitation, the three hitherto known laws of mechanics, without which classical physics is unthinkable, key physical concepts were introduced, and the heliocentric system of Copernicus was not questioned.

In terms of mathematical and physical level, “Mathematical Principles of Natural Philosophy” were an order of magnitude higher than the research of all scientists who worked on this problem before Isaac Newton. There was no unproven metaphysics with lengthy reasoning, groundless laws and unclear formulations, which was so common in the works of Aristotle and Descartes.

In 1699, while Newton was working in administrative positions, his world system began to be taught at the University of Cambridge.

Personal life

Women, neither then nor over the years, showed much sympathy for Newton, and throughout his life he never married.

The death of the great scientist occurred in 1727, and almost all of London gathered for his funeral.

Newton's laws

The first law of mechanics: every body is at rest or remains in a state of uniform translational motion until this state is corrected by the application of external forces.
The second law of mechanics: the change in momentum is proportional to the applied force and occurs in the direction of its influence.
The third law of mechanics: material points interact with each other along a straight line connecting them, with forces equal in magnitude and opposite in direction.
Law of Gravity: The force of gravitational attraction between two material points is proportional to the product of their masses multiplied by the gravitational constant, and inversely proportional to the square of the distance between these points.

There is probably not a single person in the world who does not know who Isaac Newton is. One of the world's most outstanding scientists, who made discoveries in several fields of science at once, giving rise to scientific directions in mathematics, optics, astronomy, one of the founding fathers classical physics. So, who is Isaac Newton? Today his short biography and his discoveries are widely known.

The story of a scientist and explorer

One could say about him in the words of the poet Nikolai Tikhonov: “I should make nails out of these people. There couldn’t be any stronger nails in the world.” Born before his due date, very small and weak, he lived 84 years in perfect health, until a ripe old age, devoting wholeheartedly to the development of science and engaging in government affairs. Throughout his life, the scientist adhered to strong moral principles, was a model of honesty, and did not strive for publicity and fame. Even the will of King James II did not break him.

Childhood

The scientist considered his birth on the eve of Catholic Christmas to be a special sign of providence. After all, he managed to make his greatest discoveries. Like a new star of Bethlehem, he illuminated many directions in which science subsequently developed. Many discoveries have been made thanks to the planned they are on their way.

Newton's father, who seemed an eccentric and strange man to his contemporaries, never found out about the birth of his son. A successful farmer and good owner, who just a few months did not live to see the birth of his son, left the family a significant farm and cash.

From his youth, having had a tender affection for his mother all his life, Isaac could not forgive her decision to leave him in the care of his grandparents after she married for the second time. The autobiography, compiled by him as a teenager, tells of outbursts of despair and children's plans for revenge against his mother and stepfather. He could only trust paper with the story of his emotional experiences; in life, the famous scientist was closed, didn't have close friends and was never married.

At the age of 12 he was sent to Grantham School. His closed and unsociable disposition, as well as his internal focus, turned his peers against him. From childhood, the future scientist preferred studying the natural sciences to boyish pranks. He read a lot, was interested in designing mechanical toys, and solving mathematical problems. A conflict situation with classmates prompted the proud Newton to become best student at school.

Studying at Cambridge

Having been widowed, Newton's mother really hoped that her 16-year-old son would begin to help her with farming. But through the joint efforts of the school teacher, the boy's uncle and especially Humphrey Babington, a member of Trinity College, she was able to convince her of the need for further education. In 1661, Newton took an exam in Latin and enters Trinity College at the University of Cambridge. It was in this institution that for 30 years he studied science, conducted experiments and made world discoveries.

Instead of paying for his studies at the college, where the young man first lived as a student-sizer, he had to carry out some errands for richer students and other economic work around the university. Just 3 years later, in 1664, Newton passed the exams with honors and received an advanced student category, as well as the right not only to free education, but also to a scholarship.

His studies fascinated and inspired him so much that, according to the recollections of his classmates, he could forget about sleep and food. Still engaged in mechanics and designed various things and tools, was interested in mathematical calculations, astronomical observations, research in optics, philosophy, even music theory and history.

Deciding to devote his years of life to science, he gives up love and plans to start a family. The young pupil of the pharmacist Clark, with whom he lived during his school years, also did not marry and retained a tender memory of Newton throughout her life.

First steps in scientific activity

The year 1664 was an inspiring year for the young scientist. He compiles a “Questionnaire” of 45 scientific problems and sets himself the goal of solving them all.

Thanks to the lectures of the famous mathematician I. Barrow, Newton made his first discovery of the binomial expansion, which allowed him to subsequently develop the method of differential calculus, which is used today in higher mathematics. He passes the exam successfully and receives a bachelor's degree.

Even the plague epidemic of 1665 - 1667 could not stop this inquisitive mind and force him to sit idle. During the rampant illness, Newton went home, where he continued to engage in scientific activities. Here, in the privacy of home, he does most of his great discoveries:

establishes basic methods of types of calculus - integral and differential;
deduces the theory of color and gives rise to the development of optical science;
finds a method for finding roots of quadratic equations;
derives a formula for the expansion of an arbitrary natural power of a binomial.

Important! The famous apple tree, the observations of which helped in the discovery, was preserved as a memorial bench for the scientist.

Major discoveries

Isaac Newton a brief description of his activities. He was not just a genius, a famous scientist, but a person with diverse interests in many areas of science and technology. What is he famous for and what did he discover? A keen mathematician and physicist, he was equally well versed in both the exact sciences and the humanities. Economics, alchemy, philosophy, music and history - in all these areas the genius of his talent worked. Here is just a brief description of the great discoveries of Isaac Newton:

developed a theory of the movement of celestial bodies - determined that the planets revolve around;
formulated three important laws of mechanics;
developed the theory of light and color shades;
built the world's first mirror;
discovered the Law of Gravity, thanks to which he became famous.

According to existing legend, Newton discovered the famous law while observing apples falling from an apple tree in his garden. Biographer of the famous scientist William Stukeley describes this moment in a book dedicated to the memories of Newton, which was published in 1752. According to Stukeley, it was an apple falling from a tree that gave him the idea of attraction of cosmic bodies and gravity.

“Why do apples fall perpendicular to the ground?” - thought Newton and, reflecting, deduced a new law. In the garden of the University of Cambridge, students revere and carefully care for a tree considered to be a descendant of the same “Newton’s apple tree”.

The falling of the apple served only as an impetus for the famous discovery. Newton went to him for many years, studying the works Galileo, Bullialda, Hooke, other astronomers and physicists. The scientist considered Keller’s Third Law to be another impulse. True, he composed the modern interpretation of the Law of Universal Gravitation somewhat later, when he studied the laws of mechanics.

Other scientific developments

The basis of classical mechanics is Newton’s Laws, the most important in the field of mechanics, which were formulated in a scientific work on mathematics and the principles of philosophy, published in 1687:

the first Law of uniform motion in a straight line if no other forces act on the body;
the second Law is , which in differential form describes the influence of acting forces on acceleration;
the third Law is about the force of interaction between two bodies at a certain distance.

Currently these Newton's laws are an axiom.

Astronomy

At the end of 1669, the scientist received one of the most prestigious positions in the world at Trinity College, the named Lucasian professor of mathematics and optics. In addition to a £100 salary, bonuses and scholarships, there is the opportunity to devote more time own scientific research activities. Doing experiments in optics and the theory of light, Newton creates his first reflecting telescope.

Important! The improved telescope became the main instrument for astronomers and navigators of the time. With its help, the planet Uranus was discovered and other galaxies were discovered.

Studying the celestial bodies through his reflector, the scientist developed a theory of celestial bodies and determined the movement of planets around the Sun. Using the calculations of my reflector and applying a scientific approach to Bible study, I made my own message about the end of the world. According to his calculations, this event will take place in 2060.

Government activities

1696 The great scientist holds the position of keeper of the Mint and moved to London, where he lived until 1726. Having carried out financial accounting and established order in the documentation, he becomes Montagu's co-author on carrying out monetary reform.

During the period of his activity, a branch network of the Mint was created, and the production of silver coins increased several times. Newton introduces technology, allowing you to get rid of counterfeiters.

1699 Becomes manager of the Mint. In this post he continues to fight counterfeiters. His actions as manager were as brilliant as during his scientific career. Thanks to the reforms carried out in England economic crisis was averted.

1698 A report on Newton's economic reform was presented. While in England, Tsar Peter met with the famous professor three times. In 1700, a monetary reform similar to the English one was carried out in Russia.

1689 -1690. He was a representative of Cambridge University in the country's parliament. From 1703 to 1725 he served as President of the Royal Society.

Attention! In 1705, Queen Anne of Great Britain knighted Isaac Newton. This was the only time in English history that knighthood was awarded for scientific achievements.

Biography of Newton, his discoveries

The life of the great scientist Isaac Newton

Completion of life's journey

The last months of his life the professor lived in Kensington. The great scientist died on March 20, 1727. He died in his sleep and was buried on the grounds of Westminster Abbey in the tomb of the kings and most prominent people of England. All the townspeople came to say goodbye to their famous contemporary. The funeral procession was led by the Lord Chancellor himself, followed in the funeral procession by British ministers.

Isaac Newton was born on December 25, 1642 (or January 4, 1643 according to the Gregorian calendar) in the village of Woolsthorpe, Lincolnshire.

Young Isaac, according to contemporaries, was distinguished by a gloomy, withdrawn character. He preferred reading books and making primitive technical toys to boyish pranks and pranks.

When Isaac was 12 years old, he enrolled in Grantham School. The extraordinary abilities of the future scientist were discovered there.

In 1659, at the insistence of his mother, Newton was forced to return home to farm. But thanks to the efforts of teachers who were able to discern the future genius, he returned to school. In 1661, Newton continued his education at Cambridge University.

College education

In April 1664, Newton successfully passed the exams and acquired a higher student level. During his studies, he was actively interested in the works of G. Galileo, N. Copernicus, as well as the atomic theory of Gassendi.

In the spring of 1663, lectures by I. Barrow began at the new mathematics department. The famous mathematician and prominent scientist later became a close friend of Newton. It was thanks to him that Isaac's interest in mathematics increased.

While studying in college, Newton came up with his main mathematical method - the expansion of a function into an infinite series. At the end of the same year, I. Newton received a bachelor's degree.

Notable discoveries

Studying the short biography of Isaac Newton, you should know that it was he who expounded the law of universal gravitation. Another important discovery of the scientist is the theory of the movement of celestial bodies. The 3 laws of mechanics discovered by Newton formed the basis of classical mechanics.

Newton made many discoveries in the field of optics and color theory. He developed many physical and mathematical theories. The scientific works of the outstanding scientist largely determined the time and were often incomprehensible to his contemporaries.

His hypotheses regarding the oblateness of the Earth's poles, the phenomenon of polarization of light and the deflection of light in the gravitational field still surprise scientists today.

In 1668, Newton received his master's degree. A year later he became a Doctor of Mathematical Sciences. After he created the reflector, the forerunner of the telescope, the most important discoveries were made in astronomy.

Social activity

In 1689, as a result of a coup, King James II, with whom Newton had a conflict, was overthrown. After this, the scientist was elected to parliament from the University of Cambridge, where he sat for about 12 months.

In 1679, Newton met Charles Montagu, the future Earl of Halifax. Under the patronage of Montagu, Newton was appointed custodian of the Mint.

last years of life

In 1725, the health of the great scientist began to rapidly deteriorate. He passed away on March 20 (31), 1727, in Kensington. Death occurred in a dream. Isaac Newton was buried in Westminster Abbey.

Other biography options

At the very beginning of his schooling, Newton was considered very mediocre, perhaps the worst student. He was forced to achieve his best by moral trauma when he was beaten by his tall and much stronger classmate.
In the last years of his life, the great scientist wrote a certain book, which, in his opinion, should have become some kind of revelation. Unfortunately, the manuscripts are burning. Due to the fault of the scientist's beloved dog, which knocked over the lamp, the book disappeared in the fire.
