Balfour Stewart
Balfour Stewart (1 November 182819 December 1887) was a Scottish physicist and meteorologist. His studies in the field of radiant heat led to him receiving the Rumford Medal of the Royal Society in 1868. In 1859 he was appointed director of Kew Observatory. He was elected professor of physics at Owens College, Manchester, and retained that chair until his death, which happened near Drogheda, in Ireland, on 19 December 1887. He was the author of several successful science textbooks, and also of the article on "Terrestrial Magnetism" in the ninth edition of the ''Encyclopædia Britannica''. Career Stewart was born on 1 November 1828 at 1 London Row in Leith (north of Edinburgh), the son of William Stewart a tea merchant, and his wife, Jane Clouston. His father was involved in business in Great Britain and Australia. He was educated at Dundee. He then studied Physics at the University of St Andrews, and the University of Edinburgh. Following his studies of physics at Edinburgh, ...

Edinburgh
Edinburgh is the capital city of Scotland and one of its 32 Council areas of Scotland, council areas. The city is located in southeast Scotland and is bounded to the north by the Firth of Forth and to the south by the Pentland Hills. Edinburgh had a population of in , making it the List of towns and cities in Scotland by population, second-most populous city in Scotland and the List of cities in the United Kingdom, seventh-most populous in the United Kingdom. The Functional urban area, wider metropolitan area had a population of 912,490 in the same year.

Leith
Leith (; ) is a port area in the north of Edinburgh, Scotland, founded at the mouth of the Water of Leith and is home to the Port of Leith. The earliest surviving historical references are in the royal charter authorising the construction of Holyrood Abbey in 1128 in which it is termed ''Inverlet'' (Inverleith). After centuries of control by Edinburgh, Leith was made a separate burgh in 1833 only to be merged into Edinburgh in 1920. Leith is located on the southern coast of the Firth of Forth and lies within the City of Edinburgh council area; since 2007 Leith (Edinburgh ward), it has formed one of 17 multi-member Wards of the United Kingdom, wards of the city. History As the major port serving Edinburgh, Leith has seen many significant events in Scottish history. First settlement The earliest evidence of settlement in Leith comes from several archaeological digs undertaken in The Shore, Leith, The Shore area in the late 20th century. Amongst the finds were medieval wharf ...

Magnetometer
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. In an aircraft's attitude and heading ...

Geomagnetic
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from structure of Earth, Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field at its surface ranges from . As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth. The North geomagnetic pole (Ellesmere Island, Nunavut, Canada) actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic ...

Will To Believe Doctrine
"The Will to Believe" is a lecture by William James, first published in 1896, which defends, in certain cases, the adoption of a belief without prior evidence of its truth. In particular, James is concerned in this lecture about defending the rationality of religious faith even lacking sufficient evidence of religious truth. James states in his introduction: "I have brought with me tonight ... an essay in justification of faith, a defense of our right to adopt a believing attitude in religious matters, in spite of the fact that our merely logical intellect may not have been coerced. 'The Will to Believe,' accordingly, is the title of my paper." James' central argument in "The Will to Believe" hinges on the idea that access to the evidence for whether certain beliefs are true depends crucially upon first adopting those beliefs without evidence. As an example, James argues that it can be rational to have unsupported faith in one's own ability to accomplish tasks that require con ...

Society For Psychical Research
The Society for Psychical Research (SPR) is a nonprofit organisation in the United Kingdom. Its stated purpose is to understand events and abilities commonly described as psychic or paranormal. It describes itself as the "first society to conduct organised scholarly research into human experiences that challenge contemporary scientific models." It does not, however, since its inception in 1882, hold any corporate opinions: SPR members assert a variety of beliefs with regard to the nature of the phenomena studied. Origins The Society for Psychical Research (SPR) originated from a discussion between journalist Edmund Rogers and the physicist William F. Barrett in autumn 1881. This led to a conference on 5 and 6 January 1882 at the headquarters of the British National Association of Spiritualists, at which the foundation of the Society was proposed. The committee included Barrett, Rogers, Stainton Moses, Charles Massey, Edmund Gurney, Hensleigh Wedgwood and Frederic W. H. Myers. ...

New International Encyclopedia
''The New International Encyclopedia'' was an American encyclopedia first published in 1902 by Dodd, Mead & Co. It descended from the ''International Cyclopaedia'' (1884) and was updated in 1906, 1914 and 1926. History ''The New International Encyclopedia'' was the successor of the ''International Cyclopaedia'' (1884). Initially, ''The International Cyclopaedia'' was largely a reprint of Alden's ''Library of Universal Knowledge'', which itself was a reprint of the British '' Chambers's Encyclopaedia''. The title was changed to ''The New International Encyclopedia'' in 1902, with editors Harry Thurston Peck, Daniel Coit Gilman and Frank Moore Colby. The encyclopedia was popular and reprints were made in 1904, 1905, 1907 (corrected and expanded to 20 volumes), 1909 and 1911. The 2nd edition appeared from 1914 to 1917 in 24 volumes.

Peter Guthrie Tait
Peter Guthrie Tait (28 April 18314 July 1901) was a Scottish Mathematical physics, mathematical physicist and early pioneer in thermodynamics. He is best known for the mathematical physics textbook ''Treatise on Natural Philosophy'', which he co-wrote with William Thomson, 1st Baron Kelvin, Lord Kelvin, and his early investigations into knot theory. His work on knot theory contributed to the eventual formation of topology as a mathematical discipline. His name is known in graph theory mainly for Tait's conjecture on cubic graphs. He is also one of the namesakes of the Tait–Kneser theorem on osculating circles. Early life Tait was born in Dalkeith on 28 April 1831 the only son of Mary Ronaldson and John Tait, secretary to the Walter Montagu Douglas Scott, 5th Duke of Buccleuch, 5th Duke of Buccleuch. He was educated at Dalkeith Grammar School then Edinburgh Academy, where he began his lifelong friendship with James Clerk Maxwell. He studied mathematics and physics at the ...

Pierre Prévost (physicist)
Pierre Prevost (; 3 March 1751 – 8 April 1839) was a Republic and Canton of Geneva#History, Genevan philosopher and physicist. In 1791 he explained Marc-Auguste Pictet, Pictet's experiment by arguing that all bodies radiant heat, radiate heat, no matter how hot or cold they are. Life Son of a Protestant clergyman in Geneva in the Republic and Canton of Geneva#History, Republic of Geneva, he was born in that city and was educated for a clerical career. However, he abandoned it for law, and this too he quickly deserted to devote himself to education and to travelling. He became close friends with Jean Jacques Rousseau and, a little later, with Dugald Stewart, having previously distinguished himself as a translator of and commentator on Euripides. Frederick II of Prussia secured him in 1780 as professor of philosophy and made him member of the Akademie der Wissenschaften in Berlin. He there became acquainted with Joseph Louis Lagrange and was thus led to turn his attention to ph ...

Meteorology
Meteorology is the scientific study of the Earth's atmosphere and short-term atmospheric phenomena (i.e. weather), with a focus on weather forecasting. It has applications in the military, aviation, energy production, transport, agriculture, construction, weather warnings and disaster management. Along with climatology, atmospheric physics and atmospheric chemistry, meteorology forms the broader field of the atmospheric sciences. The interactions between Earth's atmosphere and its oceans (notably El Niño and La Niña) are studied in the interdisciplinary field of hydrometeorology. Other interdisciplinary areas include biometeorology, space weather and planetary meteorology. Marine weather forecasting relates meteorology to maritime and coastal safety, based on atmospheric interactions with large bodies of water. Meteorologists study meteorological phenomena driven by solar radiation, Earth's rotation, ocean currents and other factors. These include everyday ...
