Did You Know
|
Newton was reluctant to share his research with other scientists for fear they would take credit for his discoveries.
|
|
Newton instigated a Royal Society investigation to prove that he invented calculus before German mathematician Gottfried Wilhelm Leibniz, who had published the method first.
|
|
In addition to science, Newton showed an interest in alchemy, mysticism, and theology.
|
|
French writer Voltaire first recorded the story that a falling apple gave Newton the inspiration for his theory of gravitation. Voltaire cited Newton's niece as his source for the story.
