Sir Isaac Newton laid the foundations for the creation of modern calculus through his work in the field of mathematics. His discovery of formulas that could be used to derive the areas of curved objects led to many of the mathematical breakthroughs of the last two centuries. He also helped in the field of science by discovering laws such as the universal gravitation law.
