Frederick Collier Bakewell
Frederick Collier Bakewell (29 September 1800 – 26 September 1869) was an English physicist who improved on the concept of the facsimile machine introduced by Alexander Bain in 1842 and demonstrated a working laboratory version at the 1851 World's Fair in London. Biography Born in Wakefield, West Yorkshire, he eventually moved to Hampstead, Middlesex where he lived until his death. He is buried in a family grave in Kensal Green Cemetery. Bakewell was married to Henrietta Darbyshire with whom he had two sons, Robert and Armitage. Image telegraph Bakewell's "image telegraph" had many of the features of modern facsimile machines, and replaced the pendulums of Bain's system with synchronized rotating cylinders. The system involved writing or drawing on a piece of metal foil with a special insulating ink; the foil was then wrapped around a cylinder which slowly rotated, driven by a clock mechanism. A metal stylus driven by a screw thread traveled across the surface of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Facsimile Transmission
Fax (short for facsimile), sometimes called telecopying or telefax (the latter short for telefacsimile), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black. Fax machines were ubiquitous in office environments in t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wakefield
Wakefield is a cathedral city in West Yorkshire, England located on the River Calder. The city had a population of 99,251 in the 2011 census.https://www.nomisweb.co.uk/census/2011/ks101ew Census 2011 table KS101EW Usual resident population, West Yorkshire – Wakefield BUASD, code E35000474 The city is the administrative centre of the wider City of Wakefield metropolitan district, which had a population of , the most populous district in England. It is part of the West Yorkshire Built-up Area and the Yorkshire and The Humber region. In 1888, it was one of the last group of towns to gain city status due to having a cathedral. The city has a town hall and county hall, as the former administrative centre of the city's county borough and metropolitan borough as well as county town to both the West Riding of Yorkshire and West Yorkshire, respectively. The Battle of Wakefield took place in the Wars of the Roses, and the city was a Royalist stronghold in the Civil War. Wake ...

Giovanni Caselli
Giovanni Caselli (8 June 1815 – 25 April 1891) was an Italian priest, inventor, and physicist. He studied electricity and magnetism as a child which led to his invention of the pantelegraph (also known as the universal telegraph or all-purpose telegraph), the forerunner of the fax machine. The world's first practical operating facsimile machine ("fax") system put into use was by Caselli. He had worldwide patents on his system. His technology idea was further developed into today's analog television. Caselli was a student and professor at the University of Florence in Italy. He started a technical journal that explained physics in layman's terms. For his pantelegraph technology he was awarded the Legion of Honor by Napoleon III of France. Parisian scientists and engineers started the Pantelegraph Society to exchange ideas about the pantelegraph and the associated synchronizing apparatus, in order to get the sending and receiving mechanisms to work together properly.

Natural Phenomena
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Pantelegraph
The pantelegraph (Italian: ''pantelegrafo''; French: ''pantélégraphe'') was an early form of facsimile machine transmitting over normal telegraph lines developed by Giovanni Caselli, used commercially in the 1860s, that was the first such device to enter practical service. It could transmit handwriting, signatures, or drawings within an area of up to . Description The pantelegraph used a regulating clock with a pendulum which made and broke the current for magnetizing its regulators, and ensured that the transmitter's scanning stylus and the receiver's writing stylus remained in step. To provide a time base, a large pendulum was used weighing , mounted on a frame high. Two messages were written with insulating ink on two fixed metal plates; one plate was scanned as the pendulum moved to the right and the other as the pendulum moved to the left, so that two messages could be transmitted per cycle. The receiving apparatus reproduced the transmitted image by means of paper impre ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Electric Current
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. In electric circuits the charge carriers are often electrons moving through a wire. In semiconductors they can be electrons or holes. In an electrolyte the charge carriers are ions, while in plasma, an ionized gas, they are ions and electrons. The SI unit of electric current is the ampere, or ''amp'', which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit. Electric current is measured using a device called an ammeter. Electric currents create magnetic fields, which are used in motors, generators, inductors, and transformers. In ordinary con ...

Hampstead
Hampstead () is an area in London, which lies northwest of Charing Cross, and extends from Watling Street, the A5 road (Roman Watling Street) to Hampstead Heath, a large, hilly expanse of parkland. The area forms the northwest part of the London Borough of Camden, a borough in Inner London which for the purposes of the London Plan is designated as part of Central London. Hampstead is known for its intellectual, liberal, artistic, musical, and literary associations. It has some of the most expensive housing in the London area. Hampstead has more millionaires within its boundaries than any other area of the United Kingdom.Wade, David"Whatever happened to Hampstead Man?" ''The Daily Telegraph'', 8 May 2004 (retrieved 3 March 2016).

Family Grave Of Frederick Bakewell In Kensal Green Cemetery
Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Ideally, families offer predictability, structure, and safety as members mature and learn to participate in the community. Historically, most human societies use family as the primary locus of attachment, nurturance, and socialization. Anthropologists classify most family organizations as matrifocal (a mother and her children), patrifocal (a father and his children), conjugal (a wife, her husband, and children, also called the nuclear family), avuncular (a man, his sister, and her children), or extended (in addition to parents and children, may include grandparents, aunts, uncles, or cousins). The field of genealogy aims to trace family lineages through history. The family is also an important economic unit studied in family economics. The w ...
