background

Isaac Newton was born in 1643 in England. He grew up on a farm, but he was not interested in farming. Instead, he loved reading and building mechanical toys. He went to Cambridge University to study, but the school closed because of a disease called the Great Plague. Newton had to return home for two years. During this quiet time, he thought deeply about math and nature. This period helped him develop some of his greatest ideas.

achievement

In 1687, Newton published a famous book called Principia Mathematica. In this book, he explained the three laws of motion. These laws describe how objects move and interact. He also introduced the law of universal gravitation. This idea explained that the same force pulling an apple to the ground also keeps the moon in its orbit. His mathematical work, including the creation of calculus, gave scientists new tools to study the world.

impact

Newton's discoveries laid the foundation of classical physics. His laws of motion are still taught in schools everywhere today. For over two hundred years, his ideas were the main way people understood the physical universe. Even modern space travel relies on his calculations to launch rockets. Because of his amazing work, Newton is considered one of the most important scientists in history. His curiosity completely changed human knowledge.
