Cody Dock Rolling Bridge
The Cody Dock Rolling Bridge is a moveable pedestrian bridge in London, England at Cody Dock. The bridge is manually rolled using winches to alternate between pedestrian and boat traffic. It crosses a channel that runs from River Lea to a nearby dock. It was designed by Thomas Randall-Page and Tim Lucas, and built by Cake Industries. The concept for a rectangular rolling frame came from an article titled ''Roads and Wheels'' by mathematician Stan Wagon and an interactive exhibit of square-wheeled tricycle A tricycle, sometimes abbreviated to trike, is a Human-powered transport, human-powered (or gasoline or electric motor powered or assisted, or gravity powered) Three-wheeler, three-wheeled vehicle.

Pedestrians
A pedestrian is a person traveling on foot, by wheelchair or with other mobility aids. Streets and roads often have a designated footpath for pedestrian traffic, called the ''sidewalk'' in North American English, the ''pavement'' in British English, and the ''footpath'' in Australian and New Zealand English. There are also footpaths not associated with thoroughfares; these include rural paths and urban short cuts. Historically, walking has been the main way people get around. In the early use of the word, ''pedestrian'' meant a "professional walker", or somebody who held a record for speed or endurance. With the advent of cars, it started to be used as an opposite: somebody who is not riding or driving. As walking is a healthy and sustainable mode of transport, there are efforts to make cities more walkable. For instance, by creating wider sidewalks, a pedestrian network, or restricting motor vehicles in city centres. Pedestrians are vulnerable and can be injured, for exam ...

Bicycles
A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-assisted, pedal-driven, single-track vehicle, with two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century there were more than 1 billion bicycles. There are many more bicycles than cars. Bicycles are the principal means of transport in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys. Bicycles are used for fitness, military and police applications, courier services, bicycle racing, and artistic cycling. The basic shape and configuration of a typical upright or "safety" bicycle, has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern materials and computer-aided design. These have allowed f ...

River Lea
The River Lea ( ) is in the East of England and Greater London. It originates in Bedfordshire, in the Chiltern Hills, and flows southeast through Hertfordshire, along the Essex border and into Greater London, to meet the River Thames at Bow Creek (England), Bow Creek. It is one of the largest rivers in London and the easternmost major tributary of the Thames. The river's significance as a major east–west barrier and boundary has tended to obscure its importance as north–south trade route. Below Hertford the river has since medieval times had alterations made to make it more navigable for boats between the Thames and eastern Hertfordshire and Essex, known as the Lee Navigation. This stimulated much industry along its banks. The navigable River Stort, the main tributary, joins it at Hoddesdon. While the lower Lea remains somewhat polluted, its upper stretch and tributaries, classified as chalk streams, are a major source of drinking water for London. An artificial waterway k ...

East London
East London is the part of London, England, east of the ancient City of London and north of the River Thames as it begins to widen. East London developed as London Docklands, London's docklands and the primary industrial centre. The expansion of railways in the 19th century encouraged the eastward expansion of the East End of London and a proliferation of new suburbs. The industrial lands of East London are today an area of regeneration, which are well advanced in places such as Canary Wharf and ongoing elsewhere. History Toponymy The etymology of London is uncertain, but is known to be an ancient name. The concept of East London as a distinct area is a relatively recent innovation. John Strype's map of 1720 describes London as consisting of four parts: The City of London, City and Liberty of Westminster, Westminster, Southwark and That Part Beyond the Tower. From the late 19th century the term East End of London was used to describe areas immediately adjacent to the City in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moveable Bridge
A moveable bridge, or movable bridge, is a bridge that moves to allow passage for boats or barges. In American English, the term is synonymous with , and the latter is the common term, but drawbridge can be limited to the narrower, historical definition used in some other forms of English, in which ''drawbridge'' refers to only a specific type of moveable bridge often found in castles. An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. The principal disadvantage is that the traffic on the bridge must be halted when it is opened for passage of traffic on the waterway. For seldom-used railroad bridges over busy channels, the bridge may be left open and then closed for train passages. For small bridges, bridge movement may be enabled without the need for an engine. Some bridges are operated by the users, especially those with a boat, others by a bridgeman (or bridge tender); a few are remotely controlled using video-c ...

Interactive Art
Interactive art is a form of art that involves the spectator in a way that allows the art to achieve its purpose. Some interactive art installations achieve this by letting the observer walk through, over or around them; others ask the artist or the spectators to become part of the artwork in some way. Works of this kind of art frequently feature computers, interfaces and sometimes sensors to respond to motion, heat, meteorological changes or other types of input their makers have programmed the works to respond to. Most examples of virtual Internet art and electronic art are highly interactive. Sometimes, visitors are able to navigate through a hypertext environment; some works accept textual or visual input from outside; sometimes an audience can influence the course of a performance or can even participate in it. Some other interactive artworks are considered as immersive as the quality of interaction involve all the spectrum of surrounding stimuli. Virtual reality environm ...

Tricycle
A tricycle, sometimes abbreviated to trike, is a Human-powered transport, human-powered (or gasoline or electric motor powered or assisted, or gravity powered) Three-wheeler, three-wheeled vehicle. Some tricycles, such as cycle rickshaws (for passenger transport) and freight trikes, are used for commercial purposes, especially in the developing world, particularly Africa and Asia. In the West, adult-sized tricycles are used primarily for recreation, shopping, and exercise. Tricycles are favoured by children, the disabled, and senior adults for their apparent stability versus a bicycle; however a Three-wheeler#Two rear, conventional trike may exhibit poor dynamic lateral stability, and the rider should exercise appropriate operating caution when cornering (e.g., with regard to speed, rate of turn, slope of surface) and operating technique (e.g., leaning the body 'into' the turn) to avoid tipping the trike over. Designs such as recumbents or others which place the rider lower relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Museum Of Mathematics
The National Museum of Mathematics or MoMath is a mathematics museum in Manhattan, New York City. It opened on December 15, 2012, with over thirty interactive exhibits. The mission of the museum is to "enhance public understanding and perception of mathematics". The museum is known for a special tricycle with square wheels, which operates smoothly on a catenary surface. History In 2006 the Goudreau Museum on Long Island, at the time the only museum in the United States dedicated to mathematics, closed its doors. In response, a group led by founder and former CEO Glen Whitney met to explore the opening of a new museum. They received a charter from the New York State Department of Education in 2009, and raised over 22 million dollars in under four years. With this funding, a space was leased in the Goddard Building at 11–13 East 26th Street, located in the Madison Square North Historic District. Despite some opposition to the architectural plans within the local community, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
