Edward Crisp Bullard
Sir Edward Crisp Bullard FRS (21 September 1907 – 3 April 1980) was a British geophysicist who is considered, along with Maurice Ewing, to have founded the discipline of marine geophysics. He developed the theory of the geodynamo, pioneered the use of seismology to study the sea floor, measured geothermal heat flow through the ocean crust, and found new evidence for the theory of continental drift. Early life Bullard was born into a wealthy brewing family in Norwich, England. He was educated at Norwich School and later studied Natural Sciences at Clare College, Cambridge. He studied under Ernest Rutherford at the Cavendish Laboratory of University of Cambridge and in the 1930s he received his PhD degree as a nuclear physicist. As it was the Great Depression and he was married he had to find a career to survive on. In the 1930s nuclear physics did not seem to be it so he switched to geophysics. In 1931 Bullard became a demonstrator in the department of geodesy and geop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norwich
Norwich () is a cathedral city and district of Norfolk, England, of which it is the county town. Norwich is by the River Wensum, about north-east of London, north of Ipswich and east of Peterborough. As the seat of the See of Norwich, with one of the country's largest medieval cathedrals, it is the largest settlement and has the largest urban area in East Anglia. The population of the Norwich City Council local authority area was estimated to be 144,000 in 2021, which was an increase from 143,135 in 2019. The wider built-up area had a population of 213,166 in 2019. Heritage and status Norwich claims to be the most complete medieval city in the United Kingdom. It includes cobbled streets such as Elm Hill, Timber Hill and Tombland; ancient buildings such as St Andrew's Hall; half-timbered houses such as Dragon Hall, The Guildhall and Strangers' Hall; the Art Nouveau of the 1899 Royal Arcade; many medieval lanes; and the winding River Wensum that flows through the city ...

Vetlesen Prize
The Vetlesen Prize is a prize in geology awarded jointly by Columbia University's Lamont–Doherty Earth Observatory and the G. Unger Vetlesen Foundation. The prize is generally regarded as the highest distinction in geologic studies, and the " Nobel Prize for geology". Background The Vetlesen Prize has been described as an attempt to establish an equivalent of a Nobel Prize for geophysics or geology. The prize is awarded for scientific achievement resulting in a clearer understanding of the Earth, its history, or its relations to the universe. The prize was established in 1959 and is awarded on average once every two years, if the jury selects at least one worthy candidate during this period. History G. Unger Vetlesen established the foundation which bears his name shortly before his death in 1955. In addition to the Vetlesen Prize, the foundation provides support in the Earth sciences for institutions of excellence. The prize is awarded for scientific achievement resulting in a c ...

Ernest Rutherford, 1st Baron Rutherford Of Nelson
Ernest Rutherford, 1st Baron Rutherford of Nelson, (30 August 1871 – 19 October 1937) was a New Zealand physicist who came to be known as the father of nuclear physics. ''Encyclopædia Britannica'' considers him to be the greatest experimentalist since Michael Faraday (1791–1867). Apart from his work in his homeland, he spent a substantial amount of his career abroad, in both Canada and the United Kingdom of Great Britain and Ireland, United Kingdom. In early work, Rutherford discovered the concept of radioactive half-life, the radioactive element radon, and differentiated and named Alpha decay, alpha and Beta particle, beta radiation. This work was performed at McGill University in Montreal, Quebec, Canada. It is the basis for the Nobel Prize in Chemistry he was awarded in 1908 "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances", for which he was the first Oceanian Nobel laureate, and the first to perform ...

Clare College, Cambridge
Clare College is a constituent college of the University of Cambridge in Cambridge, England. The college was founded in 1326 as University Hall, making it the second-oldest surviving college of the University after Peterhouse. It was refounded in 1338 as ''Clare Hall'' by an endowment from Elizabeth de Clare, and took on its current name in 1856. Clare is famous for its chapel choir and for its gardens on "The Backs" (the back of the colleges that overlook the River Cam). Clare is consistently one of the most popular Cambridge colleges amongst prospective applicants. History The college was founded in 1326 by the university's Chancellor, Richard Badew, and was originally named ''University Hall''. Providing maintenance for only two fellows, it soon hit financial hardship. In 1338, the college was refounded as ''Clare Hall'' by an endowment from Elizabeth de Clare, a granddaughter of Edward I, which provided for twenty fellows and ten students.

Norwich School
Norwich School (formally King Edward VI Grammar School, Norwich) is a selective English independent day school in the close of Norwich Cathedral, Norwich. Among the oldest schools in the United Kingdom, it has a traceable history to 1096 as an episcopal grammar school established by Herbert de Losinga, first Bishop of Norwich. In the 16th century the school came under the control of the city of Norwich and moved to Blackfriars' Hall following a successful petition to Henry VIII. The school was refounded in 1547 in a royal charter granted by Edward VI and moved to its current site beside the cathedral in 1551. In the 19th century it became independent of the city and its classical curriculum was broadened in response to the declining demand for classical education following the Industrial Revolution. Early statutes declared the school was to instruct 90 sons of Norwich citizens, though it has since grown to a total enrolment of approximately 1,020 pupils. For most of its hi ...

Continental Drift
Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. A pioneer of the modern view of mobilism was the Austrian geologist Otto Ampferer.Helmut W. Flügel: Die virtuelle Welt des Otto Ampferer und die Realität seiner Zeit'. In: Geo. Alp., Vol. 1, 2004. The concept was independently and more fully developed by Alfred Wegener in 1912, but the hypothesis was rejected by many for lack of any motive mechanism. The English geologist Arthur Holmes later proposed mantle convection for that mechanism. History Early history Abraham Ortelius , Theodor Christoph Lilienthal (1756), A ...

Geothermal Gradient
Geothermal gradient is the rate of temperature change with respect to increasing depth in Earth's interior. As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25–30 °C/km (72–87 °F/mi) of depth near the surface in most of the world. However, in some cases the temperature may drop with increasing depth, especially near the surface, a phenomenon known as ''inverse'' or ''negative'' geothermal gradient. The effects of weather, sun, and season only reach a depth of approximately 10-20 metres. Strictly speaking, ''geo''-thermal necessarily refers to Earth but the concept may be applied to other planets. In SI units, the geothermal gradient is expressed as °C/km, K/km, or mK/m. These are all equivalent. Earth's internal heat comes from a combination of residual heat from planetary accretion, heat produced through radioactive decay, latent heat ...

Seismology
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zha ...

Geodynamo
In physics, the dynamo theory proposes a mechanism by which a celestial body such as Earth or a star generates a magnetic field. The dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a magnetic field over astronomical time scales. A dynamo is thought to be the source of the Earth's magnetic field and the magnetic fields of Mercury and the Jovian planets. History of theory When William Gilbert published ''de Magnete'' in 1600, he concluded that the Earth is magnetic and proposed the first hypothesis for the origin of this magnetism: permanent magnetism such as that found in lodestone. In 1919, Joseph Larmor proposed that a dynamo might be generating the field. However, even after he advanced his hypothesis, some prominent scientists advanced alternative explanations. Einstein believed that there might be an asymmetry between the charges of the electron and proton so that the Earth's magnetic field would b ...

Geophysics
Geophysics () is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term ''geophysics'' sometimes refers only to solid earth applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.
