How to Feel Insignificantly Small....

"A View from the Back of the Envelope

'These pages are about approximation, and some of the fun it enables.' Examples, exercises, and links to help you grasp concepts of magnitude and scale, such as large and small numbers, the size of the world, and expressions of length, area, volume, and speed. There are sections on simplifying numbers, exponential notation, Fermi problems, using your body as a ruler, and other ways to help visualize size and scale.
