Walter Bradford Cannon
Walter Bradford Cannon (October 19, 1871 – October 1, 1945) was an American physiologist, professor and chairman of the Department of Physiology at Harvard Medical School. He coined the term "fight or flight response", and developed the theory of homeostasis. He popularized his theories in his book ''The Wisdom of the Body'', first published in 1932. Life and career Cannon was born on October 19, 1871, in Prairie du Chien, Wisconsin, the son of Colbert Hanchett Cannon and his wife Wilma Denio. His sister Ida Maud Cannon (1877-1960) became a noted hospital social worker at Massachusetts General Hospital. In his autobiography ''The Way of an Investigator'', Cannon counts himself among the descendants of Jacques de Noyon, a French Canadian explorer and coureur des bois. His Calvinist family was intellectually active, including readings from James Martineau, John Fiske (philosopher), and James Freeman Clarke. Cannon's curiosity also led him to Thomas Henry Huxley, John Tyndall, Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prairie Du Chien, Wisconsin
Prairie du Chien () is a city in and the county seat of Crawford County, Wisconsin, United States. The population was 5,506 at the 2020 census. Its ZIP Code is 53821. Often referred to as Wisconsin's second oldest city, Prairie du Chien was established as a European settlement by French voyageurs in the late seventeenth century. Its settlement date of June 17, 1673, makes it the fourth colonial settlement by European settlers in the Midwestern United States, following Green Bay, Wisconsin, Sault Ste. Marie, Michigan, and St. Ignace, Michigan. The city offers many sites showing its rich and important history in the region. The city is located near the confluence of the Wisconsin and Mississippi rivers, a strategic point along the Fox-Wisconsin Waterway that connects the Great Lakes with the Mississippi. This location offered early French missionaries and explorers their first access and entrance to the Mississippi River. Early French visitors to the site found it occupied b ...

Homeostasis
In biology, homeostasis (British also homoeostasis) (/hɒmɪə(ʊ)ˈsteɪsɪs/) is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life. Homeostasis is brought about by a natural resistance to change when already in the optimal conditions, and equilibrium is maintained by many regulatory mechanisms: it is thought to be the central motivation for all organic action. All home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Kingdon Clifford
William Kingdon Clifford (4 May 18453 March 1879) was an English mathematician and philosopher. Building on the work of Hermann Grassmann, he introduced what is now termed geometric algebra, a special case of the Clifford algebra named in his honour. The operations of geometric algebra have the effect of mirroring, rotating, translating, and mapping the geometric objects that are being modelled to new positions. Clifford algebras in general and geometric algebra in particular have been of ever increasing importance to mathematical physics, geometry, and computing. Clifford was the first to suggest that gravitation might be a manifestation of an underlying geometry. In his philosophical writings he coined the expression ''mind-stuff''. Biography Born at Exeter, William Clifford showed great promise at school. He went on to King's College London (at age 15) and Trinity College, Cambridge, where he was elected fellow in 1868, after being second wrangler in 1867 and second Smith ...

George Henry Lewes
George Henry Lewes (; 18 April 1817 – 30 November 1878) was an English philosopher and critic of literature and theatre. He was also an amateur physiologist. American feminist Margaret Fuller called Lewes a "witty, French, flippant sort of man". He became part of the mid- Victorian ferment of ideas which encouraged discussion of Darwinism, positivism, and religious skepticism. However, he is perhaps best known today for having openly lived with Mary Ann Evans, who wrote under the pen name George Eliot, as soulmates whose lives and writings were enriched by their relationship, though they never married each other. Biography Lewes, born in London, was the illegitimate son of the minor poet John Lee Lewes and Elizabeth Ashweek, and the grandson of comic actor Charles Lee Lewes. His mother married a retired sea captain when he was six. Frequent changes of home meant he was educated in London, Jersey, Brittany, and finally at Dr Charles Burney's school in Greenwich.

John Tyndall
John Tyndall FRS (; 2 August 1820 – 4 December 1893) was a prominent 19th-century Irish physicist. His scientific fame arose in the 1850s from his study of diamagnetism. Later he made discoveries in the realms of infrared radiation and the physical properties of air, proving the connection between atmospheric CO and what is now known as the greenhouse effect in 1859. Tyndall also published more than a dozen science books which brought state-of-the-art 19th century experimental physics to a wide audience. From 1853 to 1887 he was professor of physics at the Royal Institution of Great Britain in London. He was elected as a member to the American Philosophical Society in 1868. Early years and education Tyndall was born in Leighlinbridge, County Carlow, Ireland. His father was a local police constable, descended from Gloucestershire emigrants who settled in southeast Ireland around 1670. Tyndall attended the local schools (Ballinabranna Primary School) in County Carlow u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Henry Huxley
Thomas Henry Huxley (4 May 1825 – 29 June 1895) was an English biologist and anthropologist specialising in comparative anatomy. He has become known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution. The stories regarding Huxley's famous 1860 Oxford evolution debate with Samuel Wilberforce were a key moment in the wider acceptance of evolution and in his own career, although some historians think that the surviving story of the debate is a later fabrication. Huxley had been planning to leave Oxford on the previous day, but, after an encounter with Robert Chambers, the author of '' Vestiges'', he changed his mind and decided to join the debate. Wilberforce was coached by Richard Owen, against whom Huxley also debated about whether humans were closely related to apes. Huxley was slow to accept some of Darwin's ideas, such as gradualism, and was undecided about natural selection, but despite this he was wholehearted in his public support of Da ...

John Fiske (philosopher)
John Fiske (March 30, 1842 – July 4, 1901) was an American philosopher and historian. He was heavily influenced by Herbert Spencer and applied Spencer's concepts of evolution to his own writings on linguistics, philosophy, religion, and history. Biography John Fiske was born Edmund Fiske Green at Hartford, Connecticut, March 30, 1842. He was the only child of Edmund Brewster Green, of Smyrna, Delaware, and Mary Fiske Bound, of Middletown, Connecticut. His father was editor of newspapers in Hartford, New York City, and Panama, where he died in 1852, and his widow married Edwin W. Stoughton, of New York, in 1855.

James Martineau
James Martineau (; 21 April 1805 – 11 January 1900) was a British religious philosopher influential in the history of Unitarianism. For 45 years he was Professor of Mental and Moral Philosophy and Political Economy in Manchester New College (now Harris Manchester College, of the University of Oxford), the principal training college for British Unitarianism. Many portraits of Martineau, including one painted by George Frederick Watts, are held at London's National Portrait Gallery. In 2014, the gallery revealed that its patron, Catherine, Princess of Wales, was related to Martineau. The Princess's great-great-grandfather, Francis Martineau Lupton, was Martineau's grandnephew. The gallery also holds written correspondence between Martineau and Poet Laureate, Alfred, Lord Tennyson - who records that he "regarded Martineau as the mastermind of all the remarkable company with whom he engaged". Martineau and Lord Tennyson were familiar with Queen Victoria's son, Prince Le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calvinist
Calvinism (also called the Reformed Tradition, Reformed Protestantism, Reformed Christianity, or simply Reformed) is a major branch of Protestantism that follows the theological tradition and forms of Christian practice set down by John Calvin and other Reformation-era theologians. It emphasizes the sovereignty of God and the authority of the Bible. Calvinists broke from the Roman Catholic Church in the 16th century. Calvinists differ from Lutherans (another major branch of the Reformation) on the spiritual real presence of Christ in the Lord's Supper, theories of worship, the purpose and meaning of baptism, and the use of God's law for believers, among other points. The label ''Calvinism'' can be misleading, because the religious tradition it denotes has always been diverse, with a wide range of influences rather than a single founder; however, almost all of them drew heavily from the writings of Augustine of Hippo twelve hundred years prior to the Reformation.

Coureur Des Bois
A coureur des bois (; ) or coureur de bois (; plural: coureurs de(s) bois) was an independent entrepreneurial French-Canadian trader who travelled in New France and the interior of North America, usually to trade with First Nations peoples by exchanging various European items for furs. Some learned the trades and practices of the indigenous peoples. These expeditions were part of the beginning of the fur trade in the North American interior. Initially they traded for beaver coats and furs. However, as the market grew, ''coureurs de bois'' were trapping and trading prime beavers whose skins were to be felted in Europe. Evolution While French settlers had lived and traded alongside Indigenous people since the earliest days of New France, coureurs des bois reached their apex during the second half of the 17th century. After 1681, the independent coureur des bois was gradually replaced by state-sponsored voyageurs, who were workers associated with licensed fur traders. They tr ...

French Canadian
French Canadians (referred to as Canadiens mainly before the twentieth century; french: Canadiens français, ; feminine form: , ), or Franco-Canadians (french: Franco-Canadiens), refers to either an ethnic group who trace their ancestry to French colonists who settled in Canada beginning in the 17th century or to French-speaking or Francophone Canadians of any ethnic origin. During the 17th century, French settlers originating mainly from the west and north of France settled Canada. It is from them that the French Canadian ethnicity was born. During the 17th to 18th centuries, French Canadians expanded across North America and colonized various regions, cities, and towns. As a result people of French Canadian descent can be found across North America. Between 1840 and 1930, many French Canadians immigrated to New England, an event known as the Grande Hémorragie. Etymology French Canadians get their name from '' Canada'', the most developed and densely populated region of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
