Have you ever wondered where rainbows come from, or why we don't fall off the earth? A young boy named Isaac Newton asked these same questions more than 300 years ago. His search for answers unlocked secrets that gave us the world we know today. Automobiles, television, lasers, and many things that are common-place today were made possible by ideas that began inside Isaac Newton's mind. Where others took the world around them at face value, Isaac always looked deeper. He constantly searched for answers to the question, 'Why?'. His questioning mind helped us to understand the universe. It helped him to grow from a sad, lonely boy into one of the most famous scientists of all time.
