Across nine decades, Isaac Newton bestrode the world of science, becoming a colossus of experimentation, discovery and philosophy. How did a seventeenth-century Lincolnshire farm-boy become one of the most influential scientists of all time, his work still relevant to us today and for our future? This fascinating new biography explores not only Newton's world and his times but the earlier ideas that were the foundation for his breakthroughs in science and those people around him who influenced his work. His later career at the Royal Mint and his heretical views on religion are considered as extensions of his philosophy. Newton's ideas underpinned the Enlightenment that gave birth to the modern world of science and material progress. From school mathematics to space exploration, from laser surgical techniques to artificial intelligence, Newton is here in our everyday lives: the man who changed the world.
