Most Important Discoveries Of Isaac Newton

Discoveries Of Isaac Newton

Isaac Newton was astronomer ,physicist and philosopher. He was the Lucasian Professor of Mathematics at the University of Cambridge from 1669, the year he published his first book, until his death in 1727.

His Principia Mathematica (1687) describes universal gravitation and the three laws of motion which dominated scientists’ view of the physical universe for the next three centuries….

In this blog i will tell you some of the most important discoveries of isaac newton.

 

Isaac Newton And Laws Of Motion

 Isaac Newton was born on December 25, 1642. He was an English mathematician and philosopher who was one of the most influential scientists in history. He contributed to the fields of optics, gravitation, and mathematics.

Newton laws of motion:

1)An object is at rest unless acted upon by an external force.

2)The acceleration of an object is directly proportional to the force applied and inversely proportional to its mass.

3)There is an equal and opposite reaction to every action..

 

Isaac Newton And Universal Gravitation

While he was still an undergraduate student, Isaac Newton began thinking about gravity — or “universal gravitation” as it was called then — which is the force that pulls everything toward Earth’s center because everything has mass (amount of matter), even tiny fleas!

One of his most important accomplishments was discovering universal gravitation.

The force that pulls objects together is known as gravity. For example, the moon orbits around Earth because gravity attracts it toward Earth. Universal gravitation is an abstract idea that explains how gravity works across all objects in the universe.

 

Isaac Newton And Shape Of The Earth

In Principia Mathematica, Isaac Newton said that the Earth was shaped like an egg! His idea was not accepted by everyone because it did not agree with what they could see with their own eyes.

However, some people did believe him because they thought that he must have had some other evidence for this idea besides just looking at rocks and mountains!

The shape of the Earth is round, and it is not flat. This fact has been proven by Isaac Newton.

 The first indication that Newton might have been thinking about the shape of the Earth came in 1676. In a letter to Robert Hooke, he described his theory of gravity and said that he had been prompted to develop it after studying how an apple falls from a tree (the apple is attracted towards the Earth).

He went on to say that this theory could be applied to any celestial body – including planets, moons, stars and even comets .

 

Isaac Newton And Optics

Isaac Newton is best known for his discovery of the law of universal gravitation and for his contributions to the field of mathematics. However, he also made significant contributions to optics.

on December 25, 1642 Newton was born in Woolsthorpe, Lincolnshire, England. He received his education at Trinity College, Cambridge University where he studied mathematics and physics.

In 1665 Newton began lecturing on optics while still a student at Cambridge University. In 1666 he went to London and worked as an assistant to Robert Hooke at the Royal Society. It was during this time that Newton began making discoveries in optics which would revolutionize the study of light and color.

In 1672 Newton published the first edition of his Optics which included his theory of color (Opticks). This work later became known as “Newton’s Rainbow.”

 

Isaac Newton And Color Spectrum

In 1666, a year after the Great Fire of London, which destroyed most of central London, Isaac Newton discovered that white light could be split into a spectrum by a prism. This showed that white light is made up of all the colors in the rainbow.

Isaac Newton was a brilliant mathematician and scientist from England.. He made many important contributions to the science world. One of them is his theory on the color spectrum.

He believed that white light is composed of all the colors in the visible spectrum. If we pass white light through a prism, it breaks into its individual colors, which are red, orange, yellow, green, blue, indigo and violet. This is known as Newton’s color spectrum.

The theory became popular during the 18th century when artists used it to design paintings with different shades of color.

 

Isaac Newton And Law Of Cooling

The law of cooling is also known as Newton’s Law of Cooling. It is a thermodynamic law which states that the rate of change in the temperature of a body is proportional to the difference between its own temperature and the ambient temperature.

Isaac Newton was the first person to discover this law. He noticed that when he put a hot object in contact with another cooler one, both would come to the same temperature at a constant rate (the rate at which objects come to equilibrium with their surroundings).

 

Isaac Newton And Cat Door

 Isaac Newton was a man with a cat obsession. He loved his cats so much that he even wrote a book about them called “Philosophiæ Naturalis Principia Mathematica” which translates to “Mathematical Principles of Natural Philosophy”.

However, there is one story about Isaac Newton and cat door that stands out above all others.

In the late 1690s, Newton was known to be a very private person. He often kept himself locked away in his study, where he would spend hours reading and writing in his journals.

One day, while he was deep in thought, a stray cat wandered into his house and became trapped inside when it tried to exit through the front door. It was not long before the cat began scratching at the door and meowing loudly until someone came to let him out.

 

Isaac Newton Discoveries In Mathematics

 Isaac newton was a British scientist and mathematician who made significant contributions to mathematics and physics. He was an alchemist, physicist, astronomer, natural philosopher and alchemist. Newton also invented calculus.

Isaac Newton’s discoveries were many and varied. He made important contributions to the fields of mathematics, optics and physics.

He also devised a universal gravitational law, according to which every particle in the cosmos attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Newton also invented calculus, independently discovered by Gottfried Leibniz in 1684, who published his findings in 1704. Newton’s notation differs from that used today but is still useful for solving problems in physics.

In 1669, Newton applied his mathematical skills to a problem in astronomy: how to determine whether light rays were bent by their passage through a prism or whether the prism itself caused the light to divide into color bands.

To solve this problem, he had to develop a new branch of mathematics known as calculus. In 1687, he published his results in Principia Mathematica (Mathematical Principles).

 

Isaac Newton And Other Achievements

In 1689 Isaac Newton became Warden of the Mint which meant that he supervised all the mints in England so that they produced money that everyone could trust!

In 1701 Isaac Newton resigned from this post but remained active in politics until 1727 when he retired from.

While an undergraduate at Cambridge University, Newton read about the theories of Galileo Galilei who had died years earlier but whose writings were still being studied by scientists around Europe.

These theories helped inspire Newton’s own ideas about gravity which he first published in 1687. The publication of this work led him to be appointed Lucasian Professor of Mathematics at Cambridge University in 1669 at the age of twenty-seven years old!
