The shortest distance between two points is a straight line. This is one of the basic principles of Euclidean geometry. But we live on a spherical Earth, so we cannot travel the straight line path ...

The resolution of conventional imaging systems is inherently restricted by the diffraction limit, wherein the spatial information of features smaller than one-half of the wavelength is evanescent and ...

Geometry may be one of the oldest branches of mathematics, but it’s much more than a theoretical subject. It’s part of our everyday lives, says Professor Jennifer Taback, and key to understanding many ...
