ఐజాక్ న్యూటన్ - 10 నమ్మలేని నిజాలు

Telugu.news18.com.

సర్ ఐజాక్ న్యూటన్.. 9 నెలలు నిండక ముందే పుట్టాడు. పుట్టినప్పుడు చాలా చిన్నగా ఉండటంతో.. అతను చనిపోయాడేమో అని తల్లి భావించింది.

పరుషవేది (alchemy)కి న్యూటన్ ఆకర్షితుడయ్యాడు. కొన్ని రకాల లోహాలతో బంగారం తయారుచెయ్యవచ్చు అని అతను నమ్మాడు. కానీ విజయం సాధించలేదు.

తన జీవితంలో న్యూటన్ చాలా నిరాశ చెందాడు. అతనికి 50 ఏళ్ల వయసులో నరాలు చచ్చుబడ్డాయి.

న్యూటన్ అదేపనిగా తనలో తాను ఆలోచించుకునేవాడు. ఫలితంగా ఎక్కువగా ఒంటరిగా ఉండేవాడు. అతనికి ఫ్రెండ్స్ చాలా చాలా తక్కువ.

న్యూటన్ అతిగా చదివేవాడు. అతని సొంత లైబ్రరీలో 1500కి పైగా బుక్స్ ఉన్నాయి. వాటిలో మూఢనమ్మకాలు, రహస్యాలు, క్షుద్ర విద్యలవే ఎక్కువ.

న్యూటన్‌కి బైబిల్ బాగా నచ్చింది. దాని గురించి చాలా సిద్ధాంతాలు రాశాడు. ఫిజిక్స్, మేథమేటిక్స్ కంటే.. ఎక్కువగా బైబిల్ గురించి రాశాడు.

న్యూటన్‌కి డైమండ్ అని పిలిచే కుక్క ఉండేది. అది అంటే అతనికి ఎంతో ప్రేమ.

న్యూటన్‌కి అసాధారణ ప్రవర్తన ఉండేది. ఉదాహరణకు.. సూదిని కంటికి గుచ్చితే ఏమవుతుందో తెలుసుకోవడానికి ఓసారి ప్రయత్నించాడు. 

1705లో అన్నే రాణి.. న్యూటన్‌ని సైనిక వీరుడి (knighted)గా గుర్తించింది. అప్పటి నుంచి అతన్ని సర్ ఐజాక్ న్యూటన్ అని పిలుస్తున్నారు. (image credit - wikipedia)

న్యూటన్ బ్రహ్మచారి (virgin)గా చనిపోయాడు. అతనికి పిల్లలు లేరు.

Sir Isaac Newton contributed significantly to the field of science over his lifetime. He invented calculus and provided a clear understanding of optics. But his most significant work had to do with forces, and specifically with the development of a universal law of gravitation and his laws of motion . 

Isaac Newton was born on Christmas Day to a poor farming family in Woolsthorpe, England, in 1642. At the time of Newton's birth England used the Julian calendar, however, when England adopted the Gregorian calendar in 1752, his birthday became 4th January 1643. 

Isaac Newton arrived in the world only a few months after his father, Isaac Newton Sr, had died. "The boy expected to live managing the farm in the place of the father he had never known," wrote James Gleick in "Isaac Newton" ( Vintage, 2004 ). 

However, when it became clear a farming life was not for him, Newton attended Trinity College in Cambridge, England. "He did not know what he wanted to be or do, but it was not tend sheep or follow the plough and the dung cart," wrote Gleick. While there, he took an interest in mathematics, optics, physics, and astronomy . 

After his graduation, he began to teach at the college and was appointed as the second Lucasian Chair there. Today, the chair is considered the most renowned academic chair in the world, held by the likes of Charles Babbage and Stephen Hawking .

In 1689, Newton was elected as a member of parliament for the university. In 1703, he was elected as president of the Royal Society, a fellowship of scientists that still exists today. He was knighted by Queen Anne in 1705. He never married.

What are Isaac Newton's laws of motion?

Newton's most famous work came with the publication of his " Philosophiae Naturalis Principia Mathematica " ("Mathematical Principles of Natural Philosophy"), generally called Principia. In it, he determined the three laws of motion for the universe .

Newton's first law describes how objects move at the same velocity unless an outside force acts upon them. (A force is something that causes or changes motion.) Thus, an object sitting on a table remains on the table until a force — the push of a hand, or gravity — acts upon it. Similarly, an object travels at the same speed unless it interacts with another force, such as friction.

His second law of motion provided a calculation for how forces interact. The law states that a force is equal to the change in the momentum (mass multiplied by velocity) per change in time. Therefore, when more force is applied to an object, its acceleration also increases, but when the mass of the object increases and the force remains constant, its acceleration decreases.

Newton's third law states that for every action in nature, there is an equal and opposite reaction. If one body applies a force on a second, then the second body exerts a force of the same strength on the first, in the opposite direction. 

From all of this, Newton calculated the universal law of gravitation. He found that as two bodies move farther away from one another, the gravitational attraction between them decreases by the inverse of the square of the distance. Thus, if the objects are twice as far apart, the gravitational force is only a fourth as strong; if they are three times as far apart, it is only a ninth of its previous power.

These laws helped scientists understand more about the motions of planets in the solar system , and of the moon around Earth.

Related: What makes Newton's laws work? Here's the simple trick.

A popular myth tells of an apple falling from a tree in Newton's garden, which brought Newton to an understanding of forces, particularly gravity. Whether the incident actually happened is unknown, but historians doubt the event — if it occurred — was the driving force in Newton's thought process.

The myth tells of Isaac Newton having returned to his family farm in Woolsthorpe, escaping Cambridge for a short time as it was dealing with a plague outbreak. As he sat in the farm's orchard, an apple fell from one of the trees (in some tellings it hit Newton on the head). Watching this happen, Newton began to consider the forces that meant the apple always fell directly towards the ground, beginning his examination of gravity.

One of the reasons that this story gained a foothold in popular understanding is that it is an anecdote Newton himself seems to have shared. "Toward the end of his life, Newton told the apple anecdote around four times, although it only became well known in the nineteenth century," wrote Patricia Fara, a historian of science at the University of Cambridge, in a chapter of " Newton's Apple and Other Myths about Science " (Harvard University Press, 2020).

However, it would be at least 20 years before Newton published his theories on gravity. It seems more likely that Newton used the story as a means of connecting the concept of gravity's impact on objects on Earth with its impact on objects in space for his contemporary audience.

The apple tree in question — known as the "Flower of Kent" — still blooms in the orchard of Woolsthorpe Manor, and is now a popular tourist attraction.

While a student, Newton was forced to take a two-year hiatus when plague closed Trinity College. At home, he continued to work with optics, using a prism to separate white light, and became the first person to argue that white light was a mixture of many types of rays, rather than a single entity. He continued working with light and color over the next few years and published his findings in " Opticks " in 1704.

Disturbed by the problems with telescopes at the time, he invented the reflecting telescope, grinding the mirror and building the tube himself. Relying on a mirror rather than lenses, the telescope presented a sharper image than refracting telescopes at the time. Modern techniques have reduced the problems caused by lenses, but large telescopes such as the James Webb Space Telescope use mirrors. 

As a student, Newton studied the most advanced mathematical texts of his time. While on hiatus, he continued to study mathematics, laying the ground for differential and integral calculus. He united many techniques that had previously been considered separately, such as finding areas, tangents, and the lengths of curves. He wrote De Methodis Serierum et Fluxionum in 1671 but was unable to find a publisher.

Newton also established a cohesive scientific method, to be used across disciplines. Previous explorations of science varied depending on the field. Newton established a set format for experimentation still used today.

However, not all of Newton's ideas were quite as revolutionary. In P rincipia, Newton describes how rarefied vapor from comet tails is pulled into Earth's gravitational grasp and enables the movements of the planet's fluids along with the "most subtle and useful part of our air, and so much required to sustain the life of all things with us."

How did Sir Isaac Newton die?

Newton died in 1727 during his sleep at the age of 84. Although the cause of death is unknown, a 1979 study published by Newton's own Royal Society suggests mercury poisoning may have contributed to the decline of his physical and mental health. During the exhumation of his body, large amounts of mercury were found in the scientist's system, likely due to his work with alchemy. Newton conducted several experiments to convert base metals, such as mercury and copper into precious metals, such as gold and silver. 

"In 1693 Newton suffered from insomnia and poor digestion; and he also wrote irrational letters to friends. Although most scholars have attributed Newton's breakdown to psychological factors, it is possible that mercury poisoning may have been the principal cause," wrote L. W. Johnson and M. L. Wolbarsht " Mercury Poisoning: A probable cause of Isaac Newton's physical and mental ills: Notes and Records of the Royal Society of London Vol. 34. No. 1. " .

After his death, his body was moved to a more prominent place in Westminster Abbey. His white and grey marble monument stands in the nave of the Abbey's choir screen and boasts sculptures of Newton lounging surrounded by children using the many instruments, such as telescopes, associated with Newton's work. The inscription on the monument — originally written in Latin — reads: 

" Here is buried Isaac Newton, Knight, who by a strength of mind almost divine, and mathematical principles peculiarly his own, explored the course and figures of the planets, the paths of comets, the tides of the sea, the dissimilarities in rays of light, and, what no other scholar has previously imagined, the properties of the colours thus produced. Diligent, sagacious and faithful, in his expositions of nature, antiquity and the holy Scriptures, he vindicated by his philosophy the majesty of God mighty and good, and expressed the simplicity of the Gospel in his manners. Mortals rejoice that there has existed such and so great an ornament of the human race! He was born on 25th December 1642, and died on 20th March 1726. " The date of his death on his monument is given in the Julian calendar.

Isaac Newton

By: History.com Editors

Updated: October 16, 2023 | Original: March 10, 2015

Isaac Newton is best know for his theory about the law of gravity, but his “Principia Mathematica” (1686) with its three laws of motion greatly influenced the Enlightenment in Europe. Born in 1643 in Woolsthorpe, England, Sir Isaac Newton began developing his theories on light, calculus and celestial mechanics while on break from Cambridge University. 

Years of research culminated with the 1687 publication of “Principia,” a landmark work that established the universal laws of motion and gravity. Newton’s second major book, “Opticks,” detailed his experiments to determine the properties of light. Also a student of Biblical history and alchemy, the famed scientist served as president of the Royal Society of London and master of England’s Royal Mint until his death in 1727.

Isaac Newton: Early Life and Education

Isaac Newton was born on January 4, 1643, in Woolsthorpe, Lincolnshire, England. The son of a farmer who died three months before he was born, Newton spent most of his early years with his maternal grandmother after his mother remarried. His education was interrupted by a failed attempt to turn him into a farmer, and he attended the King’s School in Grantham before enrolling at the University of Cambridge’s Trinity College in 1661.

Newton studied a classical curriculum at Cambridge, but he became fascinated by the works of modern philosophers such as René Descartes, even devoting a set of notes to his outside readings he titled “Quaestiones Quaedam Philosophicae” (“Certain Philosophical Questions”). When the Great Plague shuttered Cambridge in 1665, Newton returned home and began formulating his theories on calculus, light and color, his farm the setting for the supposed falling apple that inspired his work on gravity.

Isaac Newton’s Telescope and Studies on Light

Newton returned to Cambridge in 1667 and was elected a minor fellow. He constructed the first reflecting telescope in 1668, and the following year he received his Master of Arts degree and took over as Cambridge’s Lucasian Professor of Mathematics. Asked to give a demonstration of his telescope to the Royal Society of London in 1671, he was elected to the Royal Society the following year and published his notes on optics for his peers.

Through his experiments with refraction, Newton determined that white light was a composite of all the colors on the spectrum, and he asserted that light was composed of particles instead of waves. His methods drew sharp rebuke from established Society member Robert Hooke, who was unsparing again with Newton’s follow-up paper in 1675. 

Known for his temperamental defense of his work, Newton engaged in heated correspondence with Hooke before suffering a nervous breakdown and withdrawing from the public eye in 1678. In the following years, he returned to his earlier studies on the forces governing gravity and dabbled in alchemy.

Isaac Newton and the Law of Gravity

In 1684, English astronomer Edmund Halley paid a visit to the secluded Newton. Upon learning that Newton had mathematically worked out the elliptical paths of celestial bodies, Halley urged him to organize his notes. 

The result was the 1687 publication of “Philosophiae Naturalis Principia Mathematica” (Mathematical Principles of Natural Philosophy), which established the three laws of motion and the law of universal gravity. Newton’s three laws of motion state that (1) Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it; (2) Force equals mass times acceleration: F=MA and (3) For every action there is an equal and opposite reaction.

“Principia” propelled Newton to stardom in intellectual circles, eventually earning universal acclaim as one of the most important works of modern science. His work was a foundational part of the European Enlightenment .

With his newfound influence, Newton opposed the attempts of King James II to reinstitute Catholic teachings at English Universities. King James II was replaced by his protestant daughter Mary and her husband William of Orange as part of the Glorious Revolution of 1688, and Newton was elected to represent Cambridge in Parliament in 1689. 

Newton moved to London permanently after being named warden of the Royal Mint in 1696, earning a promotion to master of the Mint three years later. Determined to prove his position wasn’t merely symbolic, Newton moved the pound sterling from the silver to the gold standard and sought to punish counterfeiters.

The death of Hooke in 1703 allowed Newton to take over as president of the Royal Society, and the following year he published his second major work, “Opticks.” Composed largely from his earlier notes on the subject, the book detailed Newton’s painstaking experiments with refraction and the color spectrum, closing with his ruminations on such matters as energy and electricity. In 1705, he was knighted by Queen Anne of England.

Isaac Newton: Founder of Calculus?

Around this time, the debate over Newton’s claims to originating the field of calculus exploded into a nasty dispute. Newton had developed his concept of “fluxions” (differentials) in the mid 1660s to account for celestial orbits, though there was no public record of his work. 

In the meantime, German mathematician Gottfried Leibniz formulated his own mathematical theories and published them in 1684. As president of the Royal Society, Newton oversaw an investigation that ruled his work to be the founding basis of the field, but the debate continued even after Leibniz’s death in 1716. Researchers later concluded that both men likely arrived at their conclusions independent of one another.

Death of Isaac Newton

Newton was also an ardent student of history and religious doctrines, and his writings on those subjects were compiled into multiple books that were published posthumously. Having never married, Newton spent his later years living with his niece at Cranbury Park near Winchester, England. He died in his sleep on March 31, 1727, and was buried in Westminster Abbey .

A giant even among the brilliant minds that drove the Scientific Revolution, Newton is remembered as a transformative scholar, inventor and writer. He eradicated any doubts about the heliocentric model of the universe by establishing celestial mechanics, his precise methodology giving birth to what is known as the scientific method. Although his theories of space-time and gravity eventually gave way to those of Albert Einstein , his work remains the bedrock on which modern physics was built.

Isaac Newton Quotes

• “If I have seen further it is by standing on the shoulders of Giants.”
• “I can calculate the motion of heavenly bodies but not the madness of people.”
• “What we know is a drop, what we don't know is an ocean.”
• “Gravity explains the motions of the planets, but it cannot explain who sets the planets in motion.”
• “No great discovery was ever made without a bold guess.”

Newton was heavily influenced by the works of previous scientists like Galileo, Descartes, and Kepler. His exposure to their ideas and his innate curiosity played a pivotal role in shaping his thoughts and theories about the natural world.

II. Newton’s Groundbreaking Discoveries

Isaac Newton gained fame for his breakthroughs in optics , mathematics (like calculus ), and most notably, for devising the three laws of motion , which are the foundational concepts of modern physics. His creation of these laws led to the development of the law of universal gravitation.

A. Laws of Motion

• First Law: Law of Inertia

Newton’s first law states that an object will remain at rest or in uniform motion unless acted upon by an external force. This principle laid the foundation for understanding inertia and the behavior of objects in motion.

• Second Law: Force and Acceleration

The second law relates the force applied to an object to its mass and acceleration, expressed by the famous equation F = ma . This law quantifies the relationship between force, mass, and acceleration, pivotal in classical mechanics.

• Third Law: Action and Reaction

Newton’s third law states that for every action, there is an equal and opposite reaction. This principle elucidates the interaction between two objects and their forces on each other.

B. Law of Universal Gravitation

Newton’s law of universal gravitation describes the force of attraction between any two masses in the universe. It mathematically demonstrates how gravity works, providing a unified explanation for celestial motions and everyday experiences on Earth.

C. Optics and the Prism Experiments

Newton’s experiments with prisms demonstrated that white light comprises a spectrum of colors. His work on optics laid the groundwork for understanding the nature of light and its behavior through different mediums.

How Isaac Newton Changed Our World

He created the modern telescope

Before Newton, standard telescopes provided magnification, but with drawbacks. Known as refracting telescopes, they used glass lenses that changed the direction of different colors at different angles. This caused “chromatic aberrations,” or fuzzy, out-of-focus areas around objects being viewed through the telescope.

After much tinkering and testing, including grinding his own lenses, Newton found a solution. He replaced the refracting lenses with mirrored ones, including a large, concave mirror to show the primary image and a smaller, flat, reflecting one, to display that image to the eye. Newton’s new “reflecting telescope” was more powerful than previous versions, and because he used the small mirror to bounce the image to the eye, he could build a much smaller, more practical telescope. In fact, his first model, which he built in 1668 and donated to England’s Royal Society, was just six inches long (some 10 times smaller than other telescopes of the era), but could magnify objects by 40x.

Newton’s simple telescope design is still used today, by both backyard astronomers and NASA scientists.

Newton helped develop spectral analysis

The next time you look up at a rainbow in the sky, you can thank Newton for helping us first understand and identify its seven colors. He began working on his studies of light and color even before creating the reflecting telescope, although he presented much of his evidence several years later, in his 1704 book, Opticks .

Before Newton, scientists primarily adhered to ancient theories on color, including those of Aristotle , who believed that all colors came from lightness (white) and darkness (black). Some even believed that the colors of the rainbow were formed by rainwater that colored the sky’s rays. Newton disagreed. He performed a seemingly endless series of experiments to prove his theories.

Working in his darkened room, he directed white light through a crystal prism on a wall, which separated into the seven colors we now know as the color spectrum (red, orange, yellow, green, blue, indigo, and violet). Scientists already knew many of these colors existed, but they believed that the prism itself transformed white light into these colors. But when Newton refracted these same colors back onto another prism, they formed into a white light, proving that white light (and sunlight) was actually a combination of all the colors of the rainbow.

Newton’s laws of motion laid the groundwork for classical mechanics

In 1687, Newton published one of the most important scientific books in history, the Philosophiae Naturalis Principia Mathematica , commonly known as the Principa . It was in this work that he first laid out his three laws of motion.

The law of inertia states that at rest or in motion will remain at rest or in motion unless it’s acted upon by an external force. So, with this law, Newton helps us explain why a car will stop when it hits a wall, but the human bodies within the car will keep moving at the same, constant speed they had been until the bodies hit an external force, like a dashboard or airbag. It also explains why an object thrown in space is likely to continue at the same speed on the same path for infinity unless it comes into another object that exerts force to slow it down or change direction.

You can see an example of his second law of acceleration when you ride a bicycle. In his equation that force equals mass times acceleration, or F=ma , your pedaling of a bicycle creates the force necessary to accelerate. Newton’s law also explains why larger or heavier objects require more force to move or alter them, and why hitting a small object with a baseball bat would produce more damage than hitting a large object with that same bat.

His third law of action and reaction creates a simple symmetry to the understanding of the world around us: For every action, there is an equal and opposite reaction. When you sit in a chair, you are exerting force down upon the chair, but the chair is exerting equal force to keep you upright. And when a rocket is launched into space, it’s thanks to the backward force of the rocket upon gas and the forward thrust of the gas on the rocket.

He created the law of universal gravitation and calculus

The Principa also contained some of Newton’s first published works on the motion of the planets and gravity. According to a popular legend, a young Newton was sitting beneath a tree on his family’s farm when the falling of an apple inspired one of his most famous theories. It’s impossible to know if this is true (and Newton himself only began telling the story as an older man), but is a helpful story to explain the science behind gravity. It also remained the basis of classical mechanics until Albert Einstein’s theory of relativity.

Newton worked out that if the force of gravity pulled the apple from the tree, then it was also possible for gravity to exert its pull on objects much, much further away. Newton’s theory helped prove that all objects, as small as an apple and as large as a planet, are subject to gravity. Gravity helped keep the planets rotating around the sun and creates the ebbs and flows of rivers and tides. Newton’s law also states that larger bodies with heavier masses exert more gravitational pull, which is why those who walked on the much smaller moon experienced a sense of weightlessness, as it had a smaller gravitational pull.

To help explain his theories of gravity and motion, Newton helped create a new, specialized form of mathematics. Originally known as “fluxions,” and now calculus, it charted the constantly changing and variable state of nature (like force and acceleration), in a way that existing algebra and geometry could not. Calculus may have been the bane of many a high school and college student, but it has proved invaluable to centuries of mathematicians, engineers and scientists.
