Sir Isaac Newton - The Ingenious Scientist About the Author in English

The story of Sir Isaac Newton's life was published in a book called "True Stories from History and Biography" by Nathaniel Hawthorne in 1851. After a lifetime of making discoveries, Newton once said: "I feel like a child playing on the beach. I pick up a nice shell or a pretty stone here and there, but the huge ocean of truth is still waiting to be found." This shows that even after so many discoveries, he felt there was still so much more to learn about the universe. His words remind us to always be curious.
