A Scientist or an Inventor?

What is the difference between a scientist and an inventor? In general terms, a scientist is a person who uses scientific methods to study the world and make discoveries and theories as to how the things around us work. An inventor takes the laws and theories of science and puts them to practical use.
Many people are both scientists and inventors. For example, Isaac Newton was a scientist when he wrote about the theory of gravity, but he was also an inventor when he made the first working reflecting telescope.
