John Benjamin Dancer
John Benjamin Dancer (8 October 1812 – 24 November 1887) was a British scientific instrument maker and inventor of microphotography. He also pioneered stereography. Life By 1835, he controlled his father's instrument making business in Liverpool. He was responsible for various inventions, but did not patent many of his ideas. In 1856, he invented the stereoscopic camera (GB patent 2064/1856). He died at the age of 75 and was buried at Brooklands Cemetery, Sale, Greater Manchester. Dancer improved the Daniell cell by introducing the porous pot cell, which he invented in 1838. He was a leading inventor and practitioner in the emerging field of microphotography, work he began shortly after the Daguerreotype process was first announced in 1839. His novel uses of microphotography, such as "the reduction of the 680-word tablet erected in memory of the electrician William Sturgeon to a positive one-sixteenth of an inch in diameter", attracted much public attention. Dancer was re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stereography
Stereoscopy (also called stereoscopics, or stereo imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word ''stereoscopy'' derives . Any stereoscopic image is called a stereogram. Originally, stereogram referred to a pair of stereo images which could be viewed using a stereoscope. Most stereoscopic methods present a pair of two-dimensional images to the viewer. The left image is presented to the left eye and the right image is presented to the right eye. When viewed, the human brain perceives the images as a single 3D view, giving the viewer the perception of 3D depth. However, the 3D effect lacks proper focal depth, which gives rise to the Vergence-Accommodation Conflict. Stereoscopy is distinguished from other types of 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye move ...

Invention
An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see human computers). Some inventions can be patented. The system of patents was established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sale, Greater Manchester
Sale is a town in Trafford, Greater Manchester, England, in the historic county of Cheshire on the south bank of the River Mersey, south of Stretford, northeast of Altrincham, and southwest of Manchester. In 2011, it had a population of 134,022, making it the largest town by population in Trafford. Evidence of Stone Age, Roman and Anglo-Saxon activity has previously been discovered locally. In the Middle Ages, Sale was a rural township, linked ecclesiastically with neighbouring Ashton upon Mersey, whose fields and meadows were used for crop and cattle farming. By the 17th century, Sale had a cottage industry manufacturing garthweb, the woven material from which horses' saddle girths were made. The Bridgewater Canal reached the town in 1765, stimulating Sale's urbanisation. The arrival of the railway in 1849 triggered Sale's growth as an important town and place for people who wanted to travel to and from Manchester, leading to an influx of middle class residents; by the ...

Daniell Cell
The Daniell cell is a type of electrochemical cell invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consists of a copper pot filled with a copper (II) sulfate solution, in which is immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode. He was searching for a way to eliminate the hydrogen bubble problem found in the voltaic pile, and his solution was to use a second electrolyte to consume the hydrogen produced by the first. Zinc sulfate may be substituted for the sulfuric acid. The Daniell cell was a great improvement over the existing technology used in the early days of battery development. A later variant of the Daniell cell called the gravity cell or crowfoot cell was invented in the 1860s by a Frenchman named Callaud and became a popular choice for electrical telegraphy. The Daniell cell is also the historical basis for the contemporary definition of the volt, which is the unit of electromotive force in ...

James Prescott Joule
James Prescott Joule (; 24 December 1818 11 October 1889) was an English physicist, mathematician and brewer, born in Salford, Lancashire. Joule studied the nature of heat, and discovered its relationship to mechanical work (see energy). This led to the law of conservation of energy, which in turn led to the development of the first law of thermodynamics. The SI derived unit of energy, the joule, is named after him. He worked with Lord Kelvin to develop an absolute thermodynamic temperature scale, which came to be called the Kelvin scale. Joule also made observations of magnetostriction, and he found the relationship between the current through a resistor and the heat dissipated, which is also called Joule's first law. His experiments about energy transformations were first published in 1843. Early years James Joule was born in 1818, the son of Benjamin Joule (1784–1858), a wealthy brewer, and his wife, Alice Prescott, on New Bailey Street in Salford. Joule was t ...

People Associated With Electricity
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...
