Have you ever wondered why apples fall to the ground or how planets move in perfect circles around the Sun? Imagine unlocking a secret so powerful that it changes the way we see the whole universe! In the late 1600s, a brilliant scientist named Isaac Newton did just that—and his discovery still impacts us today.

Isaac Newton

Isaac Newton was born in England in 1642, during a time called the Scientific Revolution when people were uncovering nature’s mysteries. His most famous claim to fame? The universal law of gravitation, which explains how objects pull on each other with invisible force. He also studied light, inventing the first reflecting telescope to see the stars more clearly.

Newton’s law of gravity says every mass attracts every other mass: that same force that makes an apple fall also keeps the Moon circling Earth! To help understand changing quantities like speed and distance, he created calculus—an amazing branch of math that scientists and engineers still use today. These breakthroughs gave us the keys to unlock both the smallest particles and the farthest galaxies.

Thanks to Newton’s ideas, we can build rockets to explore space, design safe bridges to cross rivers, and even predict eclipses! His book, ‘Principia,’ laid the foundation for classical physics and inspired generations of thinkers. Next time you see an apple drop or gaze up at the Moon, remember: it’s not magic—it’s universal gravity in action, thanks to Isaac Newton!
