Career Journey and Major Life Events
The Plague Years - The Period of Great Discoveries
Between 1665 and 1666, when Cambridge University was closed due to the plague, Newton worked from his home. During this time, he developed ideas about gravity, motion, and calculus. This period is often called his "year of wonders."
Development of Laws of Motion
Newton formulated the three laws of motion, which explain how objects move. These laws became the foundation of classical mechanics and are still taught in schools today.
Law of Universal Gravitation
Newton proposed that every object in the universe attracts every other object with a force called gravity. The famous story of an apple falling from a tree is associated with his discovery of gravitational force.
Publication of Principia
In 1687, Newton published Philosophiæ Naturalis Principia Mathematica, commonly known as the Principia. This book explained his laws of motion and universal gravitation and became one of the most important scientific works ever written.
Later Career and Public Service
Newton later served as the Warden and then Master of the Royal Mint. He was elected President of the Royal Society in 1703 and was knighted by Queen Anne in 1705, becoming Sir Isaac Newton.

Isaac Newton had a difficult early life marked by family struggles and isolation. He was born prematurely, and his father died before his birth. His mother remarried and left him in the care of his grandmother. Despite these challenges, Newton showed early interest in mechanical devices and learning, which later shaped his scientific career and achievements.
Isaac Newton was educated at Trinity College, Cambridge, where he developed his interest in mathematics and natural philosophy. He joined University of Cambridge in 1661 and studied the works of scientists like Galileo and Kepler. During the university closure due to the plague (1665–1666), Newton made major discoveries that later became central to his biography and scientific legacy.
The three laws of motion are fundamental principles that describe how objects move. These laws are key contributions in Newton’s scientific career and are widely studied in school and competitive exams.
- First Law (Law of Inertia): An object remains at rest or in uniform motion unless acted upon by an external force.
- Second Law: Force equals mass multiplied by acceleration (F = ma).
- Third Law: For every action, there is an equal and opposite reaction.
The Law of Universal Gravitation states that every object in the universe attracts every other object with a force. Proposed by Isaac Newton, this law explains the motion of planets and falling objects on Earth. It shows that gravitational force depends on the mass of objects and the distance between them, making it one of Newton’s greatest scientific contributions.
