Sir Isaac Newton Biography For Kids
Issac Newton was born on 4th January 1643 in Woolsthorpe, Lincolnshire in England. His father, who was also named Issac was a rich farmer. Sadly, Newton’s father died three months before Newton was born. When Newton was 3, his mother was remarried, and Newton was left with his grandmother. Newton studied in King’s School in Grantham, and there he was introduced to the fantastic world of Chemistry.
Newton's mother wanted him to take care of their big farm. But he failed badly as a farmer, and was sent back to school. Later he was sent to Cambridge in 1661 for further studies. that was a time when people were studying about planets, space, moon and what not. Newton was excited to be among such great minds. He graduated with very good grades, so he was given financial support for higher education.
In 1665, a deadly disease called Plague, hit the entire Europe, so the University was closed for two years. Once he sat under an Apple tree, when an apple fell down…. it made him think why do all the objects fall down and not up or sideways. That’s how the idea of gravity came in.
In the simplest words, there is a force in earth that pulls everything down. That’s why a ball goes high in the air but comes back on ground. And not just ball, it happens with all the objects.
Another very simple thought that came to Newton’s mind, was “what is light made of”. Later he discovered that light is made up of different colours. plague was over and Newton went back to Cambridge after two years. There, he became the professor of Mathematics, just at the age of 26, the youngest professor.
Newton invented a completely new type of Maths, which he called fluxions. Now, we call it Calculus. Calculus is used in advanced science and engineering studies. Newton also invented a telescope.
In 1687, in his famous book Principia, Newton gave the three laws of motion. the first law says, anything will stay stationery or in motion unless you apply an external force to change its state. The second law says that force is equal to the multiplication of mass and acceleration. And the third law says, that for every action, there is an equal and opposite reaction.
He was famous and well respected in the scientific community. In the year 1703 he was elected the president of the Royal Society. And in 1705, he was knighted by Queen Anne. That’s why he is called Sir Issac Newton and not Mr. Issac Newton or Professor Issac Newton.
