Abstract

It is often said that mathematics is everywhere. And so it is. A GPS receiver calculates its position by using the time it takes for satellite signals to reach it. Secure communications are encrypted so that they are opaque to anyone other than the recipient. The JPEG format of photos taken by a phone camera is a mathematical compression of the information contained in the photo. Without this clever compression, the photo files would be enormous.
