John Michell (MP For Horsham)
John Michell (; 25 December 1724 – 21 April 1793) was an English natural philosopher and clergyman who provided pioneering insights into a wide range of scientific fields including astronomy, geology, optics, and gravitation. Considered "one of the greatest unsung scientists of all time", he is the first person known to have proposed the existence of stellar bodies comparable to black holes, and the first to have suggested that earthquakes travelled in (seismic) waves. Recognizing that double stars were a product of mutual gravitation, he was the first to apply statistics to the study of the cosmos. He invented an apparatus to measure the mass of the Earth, and explained how to manufacture an artificial magnet. He has been called the father both of seismology and of magnetometry. According to one science journalist, "a few specifics of Michell's work really do sound like they are ripped from the pages of a twentieth century astronomy textbook."

Eakring
Eakring is a village and civil parish in the Newark and Sherwood district of Nottinghamshire, England. Its population at the 2011 census was 419, and this increased to 440 residents for the 2021 census. There was sizeable oil production there in the mid-20th century. The village's name is of Old Norse origin: ''eik-hringr'', which means "the circle of oak trees". Geography The village lies between the A617 and the A616 roads between Ollerton and Southwell. Dukes Wood to the south is situated on the top of an escarpment, giving good views over the Trent valley to the east and towards Southwell to the south. Clouds formed by the Cottam Power Station were previously seen on clear days to the northeast. A steep hill descends into the village from the south, on which the road passes a large residential training centre for National Grid plc. Heritage The village pub is the ''Savile Arms'' in Bilsthorpe Road. The Robin Hood Way, a long-distance footpath that passes through th ...

Seismic Waves
A seismic wave is a mechanical wave of acoustic wave, acoustic energy that travels through the Earth or another planetary body. It can result from an earthquake (or generally, a quake (natural phenomenon), quake), types of volcanic eruptions, volcanic eruption, magma movement, a large landslide and a large man-made explosion that produces low-frequency acoustic energy. Seismic waves are studied by seismology, seismologists, who record the waves using seismometers, hydrophones (in water), or accelerometers. Seismic waves are distinguished from seismic noise (ambient vibration), which is persistent low-amplitude vibration arising from a variety of natural and anthropogenic sources. The signal velocity, propagation velocity of a seismic wave depends on density and elasticity (physics), elasticity of the medium as well as the type of wave. Velocity tends to increase with depth through Earth's crust (geology), crust and mantle (geology), mantle, but drops sharply going from the ...

Electricity
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the Work (physics), work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing w ...

Magnetism
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, nickel, and their alloys. All substances exhibit some type of magnetism. Magnetic materials are classified according to their bulk susceptibility. Ferromagnetism is responsible for most of the effects of magnetism encountered in everyday life, but there are actually several types of magnetism. Paramagnetic substances, such as aluminium and oxygen, are weakly attracted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodwardian Professor Of Geology
The Woodwardian Professor of Geology is a professorship held in the Department of Earth Sciences at the University of Cambridge. It was founded by John Woodward in 1728 under the title of Professor of Fossils. Woodward's will left to the University a large collection of fossils and also dictated that the professor should be elected by the Archbishop of Canterbury, the Bishop of Ely, the President of the Royal Society, the President of the Royal College of Physicians, the Member of Parliament for the University of Cambridge, and the University Senate.

Praelector
A praelector is a traditional role at the University of Cambridge and the University of Oxford. The role differs somewhat between the two ancient universities. University of Cambridge At Cambridge, a praelector is the fellow of a college who formally presents students during their matriculation and the graduation ceremony at Cambridge, especially during the Congregation of the Regent House when degrees are conferred. University of Oxford At Oxford, a praelector may be a fellow of the college, but may also be a college tutor who is responsible for running an honours school in the absence of a fellow. A praelector may also hold a college fellowship. External links Praelector informationat Sidney Sussex College, Cambridge Sidney Sussex College (historically known as "Sussex College" and today referred to informally as "Sidney") is a Colleges of the University of Cambridge, constituent college of the University of Cambridge in England.

Bachelor Of Divinity
In Western universities, a Bachelor of Divinity or Baccalaureate in Divinity (BD, DB, or BDiv; ) is an academic degree awarded for a course taken in the study of divinity or related disciplines, such as theology or, rarely, religious studies. At the University of Cambridge, the Bachelor of Divinity degree is considered senior to the university's PhD degree. In the Catholic universities the Bachelor of Sacred Theology (STB) is often called the Baccalaureate in Divinity (BD) and is treated as a postgraduate qualification. In America, the BD was largely replaced by the Master of Divinity. United Kingdom Current examples of where the BD degree is taught in the United Kingdom are: the University of St Andrews (where entrants must hold a degree in another discipline); Queen's University Belfast; the University of Aberdeen; the University of Edinburgh; and the University of Glasgow. At the University of Cambridge and previously at the University of Oxford, the BD is a postgr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master Of Arts (Oxbridge And Dublin)
In the universities of University of Oxford, Oxford, University of Cambridge, Cambridge, and University of Dublin, Dublin, Bachelor of Arts, Bachelors of Arts (BAs) are promoted to the rank of Master of Arts (MA), typically upon application after three or four years after graduation. No further examination or study is required for this promotion, which is a mark of seniority rather than an additional postgraduate qualification. According to the formula of ''ad eundem gradum'', the graduates of the Universities of Oxford, Cambridge, and Dublin are eligible to apply to incorporate and be granted equivalent academic degrees at any of the other two universities, provided that they wish to register for such a degree or are members of the academic staff; they also pay a required fee. The example of the "Steamboat ladies" (roughly 720 women graduates of both Oxford and Cambridge who received Dublin academic degrees) is one of the most popular incidents of incorporation.

Kenwyn
Kenwyn () is a settlement and civil parish in Cornwall, England, United Kingdom. The settlement is a suburb of the city of Truro and lies 0.5 mi (1 km) north of the city centre, within Truro parish, whereas Kenwyn parish covers an area west and north-west of the city. Kenwyn gives its name to one of three rivers that flow through the city. The civil parish includes the villages of Threemilestone and Shortlanesend, and several hamlets including Allet, Greenbottom, Cornwall, Greenbottom and Idless. The population of the parish at the 2011 census was 5,800. History and toponymy It is likely that the church of Kenwyn was the mother church of Truro. The original dedication is possibly St Keyne; Keynwen is the earliest form of the name, which would be 'Keyn' and -wen' (white/blessed). By the 15th century, it was assumed to be St. Kenwyn, though no medieval records record it with the prefix 'Saint'. Subsequently, the dedication was attributed to St. Cybi, Cuby. The Lord of ...

American Physical Society
The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. It publishes more than a dozen scientific journals, including the prestigious '' Physical Review'' and ''Physical Review Letters'', and organizes more than twenty science meetings each year. It is a member society of the American Institute of Physics. Since January 2021, it is led by chief executive officer Jonathan Bagger. History The American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", and in one way or another the APS has been at that task ever since. In the early years, virtually the sole activity of the APS was to hold scientific m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetometry
A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil. The invention of the magnetometer is usually credited to Carl Friedrich Gauss in 1832. Earlier, more primitive instruments were developed by Christopher Hansteen in 1819, and by William Scoresby by 1823. Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials.
