All About Sir Isaac Newton – Inventions and Discoveries

Sir Isaac Newton – Inventions and Discoveries

Sir Isaac Newton was a mathematician, physicist, astronomer, alchemist, theologian, and author, born on 25th December 1642. He belongs to a poor farming family but fortunately, Newton was not a good farmer, so he was sent to Cambridge to study to become a preacher.

Newton studied mathematics at Cambridge, where he was influenced mostly by Euclid, though he was also influenced by Baconian and Cartesian philosophy. When Cambridge was closed due to the plague, Newton was compelled to depart, and it was at this time that he made some of his most important discoveries. Newton, however, did not publish his findings due to the reticence he would show later in life.

He contributed a lot to the field of science over his lifetime. He had many inventions, discoveries, and gave universal laws to the world. So, if you want to know all about Sir Isaac Newton’s inventions and discoveries, you should keep reading this blog till the end.

Sir Isaac Newton Inventions, Discoveries & Contribution to Physics

Here, we will discuss some of the famous discoveries, inventions, and laws given by Sir Isaac Newton.

Sir Isaac Newton – Famous Apple Falling Incident that Changed the World

An apple falling from a tree in Newton’s yard was the change for Newton’s knowledge of forces, notably gravity. Although it is unknown whether the incident occurred, historians dispute that it was the primary cause behind Newton’s mental process.

Isaac Newton returned to his family farm in Woolsthorpe after escaping Cambridge for a short time due to a plague outbreak. An apple fell from one of the trees in the farm’s orchard as he sat there. As he watched this happen, Newton began to think about the forces that caused the apple to constantly fall straight to the ground, thus beginning his study of gravity. This is when he discovered and taught the theory of gravitation to the world.

Sir Isaac Newton – Laws of Motion

Sir Isaac Newton gave three laws of motion to the world:

The first law shows how objects travel at the same speed unless they are acted upon by an external force. As a result, an object sitting on a table remains on the table until it is pushed off by a force, such as a hand push or gravity. Similarly, until it interacts with another force, such as friction, an object travels at the same speed.

His second rule of motion established a formula for calculating the interaction of forces. The force acting on an item is equal to its mass multiplied by its acceleration.

Newton’s third law states that there is an equal and opposite reaction to every action in nature. When one body exerts a force on another, the second body responds by exerting a force of equal strength in the opposite direction on the first.

Other Inventions & Discoveries by Sir Isaac Newton

Newton had to take a two-year break from school when the plague forced Trinity College to close. He kept working with optics at home, using a prism to separate white light and was the first to suggest that white light was a composite of many different sorts of rays rather than a single thing. Over the next few years, he continued to experiment with light and color, publishing his findings in “Opticks” in 1704.

Disturbed by the problems with telescopes at the time, he devised the reflecting telescope by polishing the mirror and hand-constructing the tube. The telescope produced a crisper image than refracting telescopes at the time because it relied on a mirror rather than lenses. Lens issues have been lessened by modern technology, but huge telescopes, such as the James Webb Space Telescope, still need mirrors.

So, this was all about Sir Isaac Newton, his discoveries, inventions and laws he has given to the world.
