Isaac Newton Biography: Born on January 4, 1643, Isaac Newton was an English physicist and mathematician. He developed the laws of motion and is regarded as one of the greatest minds of the Scientific Revolution of the 17th century. Newton’s “Philosophiae Naturalis Principia Mathematica” (“Mathematical Principles of Natural Philosophy”), published in 1687, is considered the most influential book on physics.

Isaac Newton was born in Lincolnshire, England, on January 4, 1643. Isaac, a local farmer, passed away three months before Newton was born. Isaac was Newton’s only sibling. She was Hannah Ayscough Newton, his mother. He was born prematurely. They believed he would not survive due to his fragility. However, Newton defied the odds and lived. At the age of three, Newton’s mother remarried a prosperous minister, Barnabas Smith. She moved in with him and placed Newton with his grandmother.

This experience left an indelible mark on Newton, which later manifested as a heightened sense of insecurity and anxiety. He defended his published work vigorously. Newton attended the King’s School in Grantham, Lincolnshire, where he demonstrated an early interest in science.
When he was 12 years old, his mother pulled him out of school. She desired for him to pursue farming. Newton was unhappy because he found farming difficult and monotonous. In 1661, Newton enrolled in a work-study programme at Trinity College, Cambridge.

Newton was initially taught the standard curriculum, but he had a greater interest in advanced science. During this time, Newton compiled a collection of notes titled “Quaestiones Quaedam Philosophicae” (Some Philosophical Questions). The notes outlined Newton’s new conception of nature, which laid the groundwork for the Scientific Revolution.

Newton made significant contributions to the fields of motion, optics, mathematics, and physics. He proposed that light was composed of particles and developed the theory of the light spectrum. This helped him outline the theory of gravity and the laws of motion. Newton and Gottfried Wilhelm von Leibniz are credited with developing calculus theories.

In 1668, Newton’s first major scientific accomplishment was the construction of a reflecting telescope. As a professor at Cambridge, Newton gave annual lectures on optics, his favourite subject. He utilised his telescope to study optics and assist in proving his theory on light and colour.

There are claims that Newton was engaged, but he was never in fact wed. He maintained a long-standing rivalry with Robert Hooke.
