Distance is a numerical description of how far apart objects are. In physics or everyday usage, 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 is 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".
A physical distance can be mean several different things:
Google Maps is a desktop web mapping service developed by Google. It offers satellite imagery, street maps, 360° panoramic views of streets (Street View), real-time traffic conditions (Google Traffic), and route planning for traveling by foot, car, bicycle (in beta), or public transportation.
Google Maps began as a C++ desktop program designed by Lars and Jens Eilstrup Rasmussen at Where 2 Technologies. In October 2004, the company was acquired by Google, which converted it into a web application. After additional acquisitions of a geospatial data visualization company and a realtime traffic analyzer, Google Maps was launched in February 2005. The service's front end utilizes JavaScript, XML, and Ajax. Google Maps offers an API that allows maps to be embedded on third-party websites, and offers a locator for urban businesses and other organizations in numerous countries around the world. Google Map Maker allows users to collaboratively expand and update the service's mapping worldwide.
Table tennis, also known as ping pong, is a sport in which two or four players hit a lightweight ball back and forth across a table using a small paddle. The game takes place on a hard table divided by a net. Except for the initial serve, the rules are generally as follows: Players must allow a ball played toward them to bounce one time on their side of the table, and must return it so that it bounces on the opposite side at least once. Points are scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. Spinning the ball alters its trajectory and limits an opponent's options, giving the hitter a great advantage. When doing so the hitter has a better chance of scoring if the spin is successful.
Table tennis is governed by the worldwide organization International Table Tennis Federation, founded in 1926. ITTF currently includes 220 member associations. The table tennis official rules are specified in the ITTF handbook. Table tennis has been an Olympic sport since 1988, with several event categories. In particular, from 1988 until 2004, these were: men's singles, women's singles, men's doubles and women's doubles. Since 2008, a team event has been played instead of the doubles.

There is a tool within MapInfo Professional that will allow you to calculate the distance between points in two different tables. For example, you might have a table of all of your customers, and another table of all your stores, and you wish to find the store to which each customer is closest. The distance calculator tool will perform this analysis and return a list of the customers and stores.

Determining the position of a star or other object in three-dimensional space is an important concept in astronomy. Finding stellar longitude (called right ascension) and latitude (declination) is easy enough, but it is much harder to find the radial distance to those objects. This lesson teaches how the distances to nearby stars are measured using the parallax effect: as the Earth orbits our sun, the positions of the nearest stars seem to wiggle back and forth compared to more distant stars. Knowing this parallax angle and the distance from the Earth to the sun, we can use the tangent function to measure the distance to a star. In this lesson, students will learn how parallax is measured and will practice using trigonometry to measure the height of local landmarks. They will then conduct ...
