Here is a question with a simple answer: what power do you raise 10 to in order to get 1,000? The answer is 3, because 10 to the third power is 1,000. You just computed a logarithm. Specifically, the base-10 logarithm of 1,000 is 3. That is

In 1665, the Great Plague closed Cambridge University. Isaac Newton, a 23-year-old student with no particular reputation, went home to his family's farm in Lincolnshire. Over the next two years, with nothing to do but think, he developed the theory of gravity, the laws of motion, the nature

There is a sunflower in front of you. Look at the seed head, the dense circular face where the seeds pack together. You will notice spirals. Some wind clockwise. Others wind counterclockwise. Count them. The clockwise spirals will almost certainly number 34. The counterclockwise spirals will number 55. If you
