Herbert Dingle
Herbert Dingle (2 August 1890 – 4 September 1978) was an English physicist and philosopher of science, who served as president of the Royal Astronomical Society from 1951 to 1953. He is best known for his opposition to Albert Einstein's special theory of relativity and the protracted controversy that this provoked. Biography Dingle was born in London, but spent his early years in Plymouth, where he was taken following the death of his father, and where he attended Plymouth Science, Art and Technical Schools. Due to lack of money, he left school at the age of 14 and found employment as a clerk, a job which he held for 11 years. At age 25 he won a scholarship to the Imperial College, London, from which he graduated in 1918. In that same year, Dingle married Alice Westacott who later gave birth to a son. As a Quaker, Dingle was exempt from military service during World War I. He took a position as a Demonstrator in the Physics Department, and devoted himself to the study of spect ...

Kingston Upon Hull
Kingston upon Hull, usually abbreviated to Hull, is a port city and unitary authority in the East Riding of Yorkshire, England. It lies upon the River Hull at its confluence with the Humber Estuary, inland from the North Sea and south-east of York, the historic county town. With a population of (), it is the fourth-largest city in the Yorkshire and the Humber region after Leeds, Sheffield and Bradford. The town of Wyke on Hull was founded late in the 12th century by the monks of Meaux Abbey as a port from which to export their wool. Renamed ''Kings-town upon Hull'' in 1299, Hull had been a market town, military supply port, trading centre, fishing and whaling centre and industrial metropolis. Hull was an early theatre of battle in the English Civil Wars. Its 18th-century Member of Parliament, William Wilberforce, took a prominent part in the abolition of the slave trade in Britain. More than 95% of the city was damaged or destroyed in the blitz and suffered a perio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosmology
Cosmology () is a branch of physics and metaphysics dealing with the nature of the universe. The term ''cosmology'' was first used in English in 1656 in Thomas Blount (lexicographer), Thomas Blount's ''Glossographia'', and in 1731 taken up in Latin by German philosophy, German philosopher Christian Wolff (philosopher), Christian Wolff, in ''Cosmologia Generalis''. Religious cosmology, Religious or mythological cosmology is a body of beliefs based on Mythology, mythological, Religion, religious, and Esotericism, esoteric literature and traditions of Cosmogony, creation myths and eschatology. In the science of astronomy it is concerned with the study of the chronology of the universe. Physical cosmology is the study of the observable universe's origin, its large-scale structures and dynamics, and the ultimate fate of the universe, including the laws of science that govern these areas. It is investigated by scientists, such as astronomers and physicists, as well as Philosophy, ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Ziman
John Michael Ziman (16 May 1925 – 2 January 2005) was a British-born New Zealand physicist and Humanism, humanist who worked in the area of condensed matter physics. He was a spokesman for science, as well as a teacher and author. Ziman was born in Cambridge, England, in 1925. His parents were Solomon Netheim Ziman and, Nellie Frances, née Gaster. The family emigrated to New Zealand when Ziman was a baby. He obtained his early education at Hamilton High School, New Zealand, Hamilton High School and the Victoria University College. He obtained his PhD from Balliol College, Oxford and did his early research on the theory of electrons in liquid metals at the University of Cambridge. In 1964 he was appointed professor of theoretical physics at University of Bristol, where he wrote his ''Elements Of Advanced Quantum Theory'' (1969) which explains the rudiments of quantum field theory with an elementary condensed matter slant. During this period, his interests shifted towards the ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lorentz Transformation
In physics, the Lorentz transformations are a six-parameter family of linear transformations from a coordinate frame in spacetime to another frame that moves at a constant velocity relative to the former. The respective inverse transformation is then parameterized by the negative of this velocity. The transformations are named after the Dutch physicist Hendrik Lorentz. The most common form of the transformation, parametrized by the real constant v, representing a velocity confined to the -direction, is expressed as \begin t' &= \gamma \left( t - \frac \right) \\ x' &= \gamma \left( x - v t \right)\\ y' &= y \\ z' &= z \end where and are the coordinates of an event in two frames with the origins coinciding at 0, where the primed frame is seen from the unprimed frame as moving with speed along the -axis, where is the speed of light, and \gamma = \left ( \sqrt\right )^ is the Lorentz factor. When speed is much smaller than , the Lorentz factor is negligibly different from 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin Paradox
In physics, the twin paradox is a thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more. This result appears puzzling because each twin sees the other twin as moving, and so, as a consequence of an incorrect and naive application of time dilation and the principle of relativity, each should paradoxically find the other to have aged less. However, this scenario can be resolved within the standard framework of special relativity: the travelling twin's trajectory involves two different inertial frames, one for the outbound journey and one for the inbound journey. Another way of looking at it is to realize the travelling twin is undergoing acceleration, which makes him a non-inertial observer. In both views there is no symmetry between the spacetime paths of the twins. Therefore, the twin paradox is not actually a paradox in the sense ...

Special Relativity
In physics, the special theory of relativity, or special relativity for short, is a scientific theory regarding the relationship between space and time. In Albert Einstein's original treatment, the theory is based on two postulates: # The laws of physics are invariant (that is, identical) in all inertial frames of reference (that is, frames of reference with no acceleration). # The speed of light in vacuum is the same for all observers, regardless of the motion of the light source or the observer. Origins and significance Special relativity was originally proposed by Albert Einstein in a paper published on 26 September 1905 titled "On the Electrodynamics of Moving Bodies".Albert Einstein (1905)''Zur Elektrodynamik bewegter Körper'', ''Annalen der Physik'' 17: 891; English translatioOn the Electrodynamics of Moving Bodiesby George Barker Jeffery and Wilfrid Perrett (1923); Another English translation On the Electrodynamics of Moving Bodies by Megh Nad Saha (1920).

Arthur Stanley Eddington
Sir Arthur Stanley Eddington (28 December 1882 – 22 November 1944) was an English astronomer, physicist, and mathematician. He was also a philosopher of science and a populariser of science. The Eddington limit, the natural limit to the luminosity of stars, or the radiation generated by accretion onto a compact object, is named in his honour. Around 1920, he foreshadowed the discovery and mechanism of nuclear fusion processes in stars, in his paper "The Internal Constitution of the Stars".The Internal Constitution of the Stars A. S. Eddington The Scientific Monthly Vol. 11, No. 4 (Oct., 1920), pp. 297–303 At that time, the source of stellar energy was a complete mystery; Eddington was the first to correctly speculate that the source was fusion of hydrogen into helium. Eddington wrote a number of articles that announced and explained Einstein's theory of general relativity to the English-speaking world. World War I had severed many lines of scientific communication, and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
