Now and then there is a bright radio flash somewhere in the sky. It can last anywhere from a few milliseconds to a few seconds. They appear somewhat at random, and we still aren't sure what they are.

In astronomy, where distances are too vast to measure with an ordinary ruler, geometry has long been the workhorse. Now, a new study has turned that ancient mathematical language into a precision tool ...

An underrated feature in Google Maps is the ability to measure the distance between two or more points. It can aid tremendously with planning, whether you’re aiming to walk or go on a road trip.

Metric measure spaces serve as a unifying setting for analysis and geometry beyond the classical Euclidean framework. Equipped with a metric to quantify distances and a measure to assess size, these ...
