Spacetime

In physics, spacetime is any mathematical model that combines space and time into a single interwoven continuum. The spacetime of our universe has historically been interpreted from a Euclidean space perspective, which regards space as consisting of three dimensions, and time as consisting of one dimension, the "fourth dimension". By combining space and time into a single manifold called Minkowski space, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.

Explanation

In non-relativistic classical mechanics, the use of Euclidean space instead of spacetime is appropriate, because time is treated as universal with a constant rate of passage that is independent of the state of motion of an observer. In relativistic contexts, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer and also on the strength of gravitational fields, which can slow the passage of time for an object as seen by an observer outside the field.

Voi

Voi is the largest town in Taita-Taveta County in southern Kenya, in the former Coast Province. It lies at the western edge of the Taru Desert, south and west of the Tsavo East National Park. The Sagala Hills are to the south. Voi is also a municipality.

Economy

Voi is a marketplace for the agricultural and meat products from the fertile Taita Hills as well as other surrounding areas. Voi's town centre consists of mostly general stores, shops, markets, kiosks and a few hotels. Most lodges that service tourists for the national park are located in the suburbs at the edge of town. The Voi Sisal Estates are located to the west of the town. A large squatter community exists in the Mwatate Sisal Estates, also to the west of town.

History

According to local history the name of town comes from a slave trader called Chief Kivoi who settled near the Voi River about 400 years ago. There after the village grew as a trading centre for the local Taita people with other Kenyan tribes and Arabs.

The town started to grow at the end of the 19th century when the Uganda Railway was constructed. People started to move in to work on the railway and the nearby sisal estates. However, township status with an area of about 16.27 square kilometres (6.28 sq mi) was not granted until 1932. The town has long since outgrown the original grant.
