Newton's Impact 
Of all the branches of physics, mechanics has the most scientific and practical consequences.
- Mechanical and Structural Engineering
- Aeronautics and Astronautics
- Astronomy
Newton is generally considered the greatest scientist who has yet lived because he invented the theoretical scientific approach, invented a new mathematics (calculus) and because his work has had such an impact on future (i.e. present-day) science and technology. A further reason for his greatness is that his laws overthrew centuries of careful thought about motion by some very intelligent people (chief among them Aristotle).
