Here’s an interesting paradoxical puzzle told to me by my friend Bryan, known as the two envelopes problem. And my proposed resolution of it. Call the amount of money in the envelope you selected (a ). If you stay with your initial choice, you are guaranteed this amount. The paradox is that this is absurd, since...

Photos usually only show a rectangular fragment of the scene when the image was taken. Typical panoramic images display more of a landscape, but they still don’t capture the whole picture. Even a 360˚ panorama only captures a horizontal circle, leaving out the ground and sky. Tools for creating panoramic images.

A collection of art and math projects by a Physics student. With help from a friend. Who likes blog posts. Table of contents. Weaving sounds to make braids. Vi Hart’s “Doodle Music” video is a beautiful combination of art, math and music, illustrating parallels between symmetries in curves and symmetries in sound:. I particularly enjoyed the braid melody at 2:35. So it made me want to discover a mathematical function governing the vibrations in the air that define a “musical braid”. Looking at the braid.
