Sir Isaac Newton was born in 1642 in Woolsthorpe near Grantham, England. He belonged to a poor family. His interest was not in farming, instead, he went for studies at Cambridge University in the year 1661.

In the year 1665, the incident of a falling apple happened. This incident made him think about the gravity of force which intact moon in its orbit. This gave birth to the invention of the universal law of gravitation. He was the first person to discover gravity.

Newton gave laws of motion. Along with it, he worked on light and colour. To do observations on astrology, he designed an astronomical telescope. He was good at mathematics so and invented calculus.
