From Tardis Wiki, the free Doctor Who reference
Isaac Newton (1642-1727) was an English physicist and mathematician. One of his most famous accomplishments was formulating the theory of gravity.
He is also known for his quote:
- "For every action, there is an equal and opposite reaction."
This quote lead Romana to believe that Newton invented punting. (DW: The Five Doctors)
The Doctor once claimed that he sat in Newton's tree dropping apples onto his head, then explained gravity to him over dinner. (DW: The Pirate Planet)
