Sunspottery
Sunspottery was a pejorative term assigned to a late 19th century trend to ascribe sunspots and their cycles as causes for various cyclic phenomena, including disease outbreaks and economic crises. William Stanley Jevons read a paper ''On the influence of the sun-spot period upon the price of corn'' at a meeting of the ''British Association for the Advancement of Science The British Science Association (BSA) is a charity and learned society founded in 1831 to aid in the promotion and development of science. Until 2009 it was known as the British Association for the Advancement of Science (BA). The current Chie ...'' in 1875. This was followed by a great deal of media interest and a period when it became fanciful to blame the sun for all kinds of events, with the term being used pejoratively in the newspapers. Jevons later wrote to the '' Times'' in April 1879 stating that despite the abuse of his idea "the activity of commerce in England ultimately depends upon the solar activ ...

Sunspot
Sunspots are phenomena on the Sun's photosphere that appear as temporary spots that are darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection. Sunspots appear within active regions, usually in pairs of opposite magnetic polarity. Their number varies according to the approximately 11-year solar cycle. Individual sunspots or groups of sunspots may last anywhere from a few days to a few months, but eventually decay. Sunspots expand and contract as they move across the surface of the Sun, with diameters ranging from to . Larger sunspots can be visible from Earth without the aid of a telescope. They may travel at relative speeds, or proper motions, of a few hundred meters per second when they first emerge. Indicating intense magnetic activity, sunspots accompany other active region phenomena such as coronal loops, prominences, and reconnection events. Most solar flares and coronal mas ...

William Stanley Jevons
William Stanley Jevons (; 1 September 183513 August 1882) was an English economist and logician. Irving Fisher described Jevons's book ''A General Mathematical Theory of Political Economy'' (1862) as the start of the mathematical method in economics. It made the case that economics, as a science concerned with quantities, is necessarily mathematical. In so doing, it expounded upon the "final" (marginal) utility theory of value. Jevons' work, along with similar discoveries made by Carl Menger in Vienna (1871) and by Léon Walras in Switzerland (1874), marked the opening of a new period in the history of economic thought. Jevons's contribution to the marginal revolution in economics in the late 19th century established his reputation as a leading political economist and logician of the time. Jevons broke off his studies of the natural sciences in London in 1854 to work as an assayer in Sydney, where he acquired an interest in political economy. Returning to the UK in 1859, h ...

British Science Association
The British Science Association (BSA) is a charity and learned society founded in 1831 to aid in the promotion and development of science. Until 2009 it was known as the British Association for the Advancement of Science (BA). The current Chief Executive is Katherine Mathieson. The BSA's mission is to get more people engaged in the field of science by coordinating, delivering, and overseeing different projects that are suited to achieve these goals. The BSA "envisions a society in which a diverse group of people can learn and apply the sciences in which they learn." and is managed by a professional staff located at their Head Office in the Wellcome Wolfson Building. The BSA offers a wide variety of activities and events that both recognize and encourage people to be involved in science. These include the British Science Festival, British Science Week, the CREST Awards, Huxley Summit, Media Fellowships Scheme, along with regional and local events. History Foundation The Asso ...

The Times
''The Times'' is a British daily national newspaper based in London. It began in 1785 under the title ''The Daily Universal Register'', adopting its current name on 1 January 1788. ''The Times'' and its sister paper ''The Sunday Times'' (founded in 1821) are published by Times Newspapers, since 1981 a subsidiary of News UK, in turn wholly owned by News Corp. ''The Times'' and ''The Sunday Times'', which do not share editorial staff, were founded independently and have only had common ownership since 1966. In general, the political position of ''The Times'' is considered to be centre-right. ''The Times'' is the first newspaper to have borne that name, lending it to numerous other papers around the world, such as ''The Times of India'', ''The New York Times'', and more recently, digital-first publications such as TheTimesBlog.com (Since 2017). In countries where these other titles are popular, the newspaper is often referred to as , or as , although the newspaper is of nationa ...

The Globe (London Newspaper)
''The Globe'' was a British newspaper that ran from 1803 to 1921. It was founded by Christopher Blackett, the coal mining entrepreneur from Wylam, Northumberland, who had commissioned the first commercially useful adhesion steam locomotives in the world. It merged with the ''Pall Mall Gazette'' in 1921. Under the ownership of Robert Torrens during the 1820s it supported radical politics, and was regarded as closely associated with Jeremy Bentham. By the 1840s it was more mainstream and received briefings from within the Whig administration. In 1871 it was owned by a Tory group headed by George Cubitt, who brought in George Armstrong as editor. It was controlled by Max Aitken shortly before World War I. Turnovers In journalism, turnovers are articles which run beyond the page that they begin on, forcing the reader to turnover. In the case of the Globe, the term has a special meaning. Turnovers for the Globe were essays and sketches, either social, descriptive or humorous, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humbug
A humbug is a person or object that behaves in a deceptive or dishonest way, often as a hoax or in jest. The term was first described in 1751 as student slang, and recorded in 1840 as a "nautical phrase". It is now also often used as an exclamation to describe something as hypocritical nonsense or gibberish. When referring to a person, a humbug means a fraud or impostor, implying an element of unjustified publicity and spectacle. In modern usage, the word is most associated with the character Ebenezer Scrooge, created by Charles Dickens in his 1843 novella ''A Christmas Carol''. His famous reference to Christmas, "Bah! Humbug!", declaring Christmas to be a fraud, is commonly used in stage and screen versions and also appeared frequently in the original book. The word is also prominently used in the 1900 book ''The Wonderful Wizard of Oz'', in which the Scarecrow refers to the Wizard of Oz as a humbug, and the Wizard agrees. Another use of the word was by John Collins Warren, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Cycle
The solar cycle, also known as the solar magnetic activity cycle, sunspot cycle, or Schwabe cycle, is a nearly periodic 11-year change in the Sun's activity measured in terms of variations in the number of observed sunspots on the Sun's surface. Over the period of a solar cycle, levels of solar radiation and ejection of solar material, the number and size of sunspots, solar flares, and coronal loops all exhibit a synchronized fluctuation from a period of minimum activity to a period of a maximum activity back to a period of minimum activity. The magnetic field of the Sun flips during each solar cycle, with the flip occurring when the solar cycle is near its maximum. After two solar cycles, the Sun's magnetic field returns to its original state, completing what is known as a Hale cycle. This cycle has been observed for centuries by changes in the Sun's appearance and by terrestrial phenomena such as aurora but was not clearly identified until 1843. Solar activity, driven by ...

Brückner-Egeson-Lockyer Cycle
The Brückner-Egeson-Lockyer cycle is a climatic cycle of approximately 30-40 years. Originally described by Charles Egeson on the basis of periodic flooding events in southern Australia that correlated with sunspot activity. It was supported by William J.S. Lockyer and later by Eduard Brückner. The initials "BEL" or paratridecadal cycles have since been suggested to explain various other long-term cycles including those affecting economics, human physiology, and historical events. Charles Egeson (who possibly also went by the name of John Joseph George) first suggested 33 year cycles in Australian weather in 1889. Egeson was an assistant to Henry Chamberlain Russell in the Sydney Observatory. When Russell was away in Europe, he began to publish forecasts based on his cycles in the newspapers. The forecast of a drought caused considerable public alarm and led to his dismissal from the Sydney Observatory in 1890. In 1893, a warrant was issued for the arrest of Charles Egeson in a ...

Sunspots (economics)
In economics, the term sunspots (or sometimes "a sunspot") refers to an ''extrinsic'' random variable, that is, a random variable that does not affect economic fundamentals (such as endowments, preferences, or technology). ''Sunspots'' can also refer to the related concept of extrinsic uncertainty, that is, economic uncertainty that does not come from variation in economic fundamentals. David Cass and Karl Shell coined the term ''sunspots'' as a suggestive and less technical way of saying "extrinsic random variable". Use The idea that arbitrary changes in expectations might influence the economy, even if they bear no relation to fundamentals, is controversial but has been widespread in many areas of economics. For example, in the words of Arthur C. Pigou, :The varying expectations of business men... and nothing else, constitute the immediate cause and direct causes or antecedents of industrial fluctuations. 'Sunspots' have been included in economic models as a way of capturi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
