Sir Oliver Joseph Lodge
Sir Oliver Joseph Lodge, (12 June 1851 – 22 August 1940) was a British physicist and writer involved in the development of, and holder of key patents for, radio. He identified electromagnetic radiation independent of Hertz's proof and at his 1894 Royal Institution lectures ("''The Work of Hertz and Some of His Successors''"), Lodge demonstrated an early radio wave detector he named the "coherer". In 1898 he was awarded the "syntonic" (or tuning) patent by the United States Patent Office. Lodge was Principal of the University of Birmingham from 1900 to 1920. Lodge was also noted for his Spiritualist beliefs and pseudoscientifc research into life after death, a topic on which he wrote many books, including the best-selling ''Raymond; or, Life and Death'' (1916), describing what he believed to be detailed messages through a medium from his deceased adult son who was killed in World War I.

Penkhull
Penkhull is a district of the city of Stoke-on-Trent, Staffordshire, England, part of Penkhull and Stoke electoral ward, and Stoke Central parliamentary constituency. Penkhull is a conservation area, and includes Grade II listed buildings such as the church and Greyhound Inn public house. History ''The Victoria History of the County of Stafford: Volume 8'' (1965) suggests that name arises from the British ''pencet'' ('end or head of the wood') and the Old English ''hyll'' (hill). Ward (1843) also mentioned the possibility of the Celtic British ''Pen'' (head) and ''Kyl'' (kiln). The idea of a 'head' or 'end' is topographically apt, since the village is sited on the elevated end of a long strip of valley-side woodland which begins at the ancient Bradwell Wood five miles to the north. The early origins date from 2500 BC, and there have been three archaeological finds from this period. A study by the local city Council stated of Penkhull that...

Staffordshire Potteries
The Staffordshire Potteries is the industrial area encompassing the six towns Burslem, Fenton, Hanley, Longton, Stoke and Tunstall, which is now the city of Stoke-on-Trent in Staffordshire, England. North Staffordshire became a centre of ceramic production in the early 17th century, Fleming, John & Hugh Honour. (1977) ''The Penguin Dictionary of Decorative Arts. '' London: Allen Lane, p. 752. due to the local availability of clay, salt, lead and coal. Spread Hundreds of companies produced all kinds of pottery, from tablewares and decorative pieces to industrial items. The main pottery types of earthenware, stoneware and porcelain were all made in large quantities, and the Staffordshire industry was a major innovator in developing new varieties of ceramic bodies such as bone china and jasperware, as well as pioneering transfer printing and other glazing and decorating techniques. In general Staffordshire was strongest in the middle and low price ranges, though the finest an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediumship
Mediumship is the practice of purportedly mediating communication between familiar spirits or ghost, spirits of the dead and living human beings. Practitioners are known as "mediums" or "spirit mediums". There are different types of mediumship or spirit conduit (channeling), channelling, including table-turning, séance tables, trance, and ouija. Belief in psychic ability is widespread despite the absence of objective evidence for its existence. Scientific researchers have attempted to ascertain the validity of claims of mediumship. An experiment undertaken by the British Psychological Society led to the conclusion that the test subjects demonstrated no mediumistic ability. Mediumship gained popularity during the nineteenth century, when ouija boards were used as a source of entertainment. Investigations during this period revealed widespread fraud—with some practitioners employing techniques used by Magic (illusion), stage magicians—and the practice began to lose credibilit ...

Pseudoscience
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or falsifiability, unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to Peer review, evaluation by other experts; absence of systematic practices when developing Hypothesis, hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. The demarcation problem, demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theory, scientific theories and pseudoscientific beliefs, but there is general agreement on examples such as ancient astronauts, climate change denial, dowsing, evolution denial, ...

Spiritualism
Spiritualism is the metaphysical school of thought opposing physicalism and also is the category of all spiritual beliefs/views (in monism and dualism) from ancient to modern. In the long nineteenth century, Spiritualism (when not lowercase) became most known as a social religious movement according to which the laws of nature and of God include "the continuity of consciousness after the transition of death" and "the possibility of communication between those living on Earth and those who have made the transition". The afterlife, or the " spirit world", is seen by spiritualists not as a static place, but as one in which spirits continue to evolve. These two beliefs—that contact with spirits is possible, and that spirits are more advanced than humans—lead spiritualists to a third belief: that spirits are capable of providing useful insight regarding moral and ethical issues, as well as about the nature of God. Some spiritualists will speak of a concept which they refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coherer
The coherer was a primitive form of radio signal detector used in the first radio receivers during the wireless telegraphy era at the beginning of the 20th century. Its use in radio was based on the 1890 findings of French physicist Édouard Branly and adapted by other physicists and inventors over the next ten years. The device consists of a tube or capsule containing two electrodes spaced a small distance apart with loose metal filings in the space between. When a radio frequency signal is applied to the device, the metal particles would cling together or " cohere", reducing the initial high resistance of the device, thereby allowing a much greater direct current to flow through it. In a receiver, the current would activate a bell, or a Morse paper tape recorder to make a record of the received signal. The metal filings in the coherer remained conductive after the signal (pulse) ended so that the coherer had to be "decohered" by tapping it with a clapper actuated by an electroma ...

Royal Institution
The Royal Institution of Great Britain (often the Royal Institution, Ri or RI) is an organisation for scientific education and research, based in the City of Westminster. It was founded in 1799 by the leading British scientists of the age, including Henry Cavendish and its first president, George Finch. Its foundational principles were diffusing the knowledge of, and facilitating the general introduction of useful mechanical inventions and improvements, as well as enhancing the application of science to the common purposes of life (including through teaching, courses of philosophical lectures, and experiments). Much of the Institution's initial funding and the initial proposal for its founding were given by the Society for Bettering the Conditions and Improving the Comforts of the Poor, under the guidance of philanthropist Sir Thomas Bernard and American-born British scientist Sir Benjamin Thompson, Count Rumford. Since its founding it has been based at 21 Albemarle Street ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electromagnetic Radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic field, electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, Light, (visible) light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum. Classical electromagnetism, Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric field, electric and magnetic fields. Depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted ''c''. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The position of an electromagnetic wave w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
