Early humans won at running; Neandertals won at walking

(PhysOrg.com) -- New research has compared the performance of the heels of modern-day distance runners to the heels of Neandertals and ancient Homo sapiens. The results show the Neandertals' heels were taller than those of ...

Mathematicians develop new statistical indicator

Most of us know this phenomenon only too well: when it's hot outside, you feel the urge for a cooling ice cream. But would you have thought that mathematics could be involved?

Using stellar 'twins' to reach the outer limits of the galaxy

Astronomers from the University of Cambridge have developed a new, highly accurate method of measuring the distances between stars, which could be used to measure the size of the galaxy, enabling greater understanding of ...

Distance

Distance (or farness) is a numerical description of how far apart objects are. In physics or everyday discussion, distance may refer to a physical length, or an estimation based on other criteria (e.g. "two counties over"). In mathematics, a distance function or metric is a generalization of the concept of physical distance. A metric is a function that behaves according to a specific set of rules, and provides a concrete way of describing what it means for elements of some space to be "close to" or "far away from" each other.

In most cases, "distance from A to B" is interchangeable with "distance between B and A".
