Francis Darwin
Sir Francis "Frank" Darwin (16 August 1848 – 19 September 1925) was a British botanist. He was the third son of the naturalist and scientist Charles Darwin. Biography Francis Darwin was born in Down House, Downe, Kent in 1848. He was the third son and seventh child of Charles Darwin and his wife Emma Wedgwood. He was educated at Clapham Grammar School. He then went to Trinity College, Cambridge, first studying mathematics, then changing to natural sciences, graduating in 1870. He then went to study medicine at St George's Medical School, London, earning an MB in 1875, but did not practise medicine. Darwin was married three times and widowed twice. First he married Amy Richenda Ruck in 1874, but she died in 1876 four days after the birth of their son Bernard Darwin, who was later to become a golf writer. In September 1883 he married Ellen Wordsworth Crofts (1856–1903) and they had a daughter Frances Crofts Darwin (1886–1960), a poet who married the poet Fran ...

Down House
Down House is the former home of the English naturalist Charles Darwin and his family. It was in this house and garden that Darwin worked on his theory of evolution by natural selection, which he had conceived in London before moving to Down. The Grade I listed building stands in Luxted Road, south of Downe, a village south-east of London's Charing Cross. The village was still known as Down when Darwin moved there in 1842. In his day, Downe was a parish in Kent, but it subsequently came under Bromley Rural District. Since 1965, it has lain within the London Borough of Bromley. The house, garden and grounds are in the guardianship of English Heritage. They have been restored and are open to the public. History of Down House In 1651, Thomas Manning sold a parcel of land including most of the current property to John Know the elder, from a Kentish yeoman family, for £345 (equivalent to £ today). It has been debated whether this price is likely to have included a hous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernard Darwin
Bernard Richard Meirion Darwin CBE JP (7 September 1876 − 18 October 1961) a grandson of the British naturalist Charles Darwin, was a golf writer and high-standard amateur golfer. He was inducted into the World Golf Hall of Fame. Biography Born in Downe, Kent, Darwin was the son of Francis Darwin and Amy Ruck, his mother dying from a fever on 11 September, four days after his birth. He was the first grandson of Charles and Emma Darwin (see Darwin–Wedgwood family), and was brought up by them at their home, Down House. His younger half-sister from his father's second marriage to Ellen Wordswotth Crofts was the poet Frances Cornford. Darwin was educated at Eton College, and graduated in law from Trinity College, Cambridge, where he was a Cambridge Blue in golf 1895-1897, and team captain in his final year. Darwin married the engraver Elinor Monsell in 1906. They had one son, Sir Robert Vere Darwin, and two daughters; the potter Ursula Mommens, and Nicola Mary Elizabeth ...

Cotyledon
A cotyledon (; ; ; , gen. (), ) is a significant part of the embryo within the seed of a plant, and is defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed." The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous ("monocots"). Plants with two embryonic leaves are termed dicotyledonous ("dicots"). In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons are formed during embryogenesis, along with the root and shoot meristems, and are therefore present in the seed prior to germination. True leaves, however, are formed post-embryonically (i.e. after germination) from the shoot apical meristem, which is responsible for generating subsequent aerial ...

Insectivorous Plants (book)
''Insectivorous Plants'' is a book by British naturalist and evolutionary theory pioneer Charles Darwin, first published on 2 July 1875 in London. Part of a series of works by Darwin related to his theory of natural selection, the book is a study of carnivorous plants with specific attention paid to the adaptations that allow them to live in difficult conditions. It includes illustrations by Darwin himself, along with drawings by his sons George and Francis Darwin. The book chronicles Darwin's experiments with various carnivorous plants, in which he carefully studied their feeding mechanisms. Darwin tried several methods to stimulate the plants into activating their trap mechanisms, including feeding them meat and glass, blowing on them and prodding them with hair. He found that only the movement of an animal would cause the plants to react, and concluded that this was an evolutionary adaptation to conserve energy for prey and to ignore stimuli that were not likely to be nutr ...

The Power Of Movement In Plants
''The Power of Movement in Plants'' is a book by Charles Darwin on phototropism and other types of movement in plants. This book continues his work in producing evidence for his theory of natural selection. As it was one of his last books, followed only by the publication of ''The Formation of Vegetable Mould through the Action of Worms'', he was assisted by his son Francis in conducting the necessary experiments and preparing the manuscript. The ''Power of Movement in Plants'' was published 6 November 1880, and 1500 copies were quickly sold by publisher John Murray.''The Life and Letters of Charles Darwin, Vol II.'' 1959. Francis Darwin, ed. Basic Books Inc., New York. p. 502-510. This book stands at the culmination of a long line of study in plants and is immediately preceded by 'The different forms of flowers on Plants of the same species’ (1877). (See Bibliography for additional publications on plants.) These studies on plants were first evidenced in 'On the various con ...

Phototropism
Phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the furthest side from the light. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Negative phototropism is not to be confused with skototropism which is defined as the growth towards darkness, whereas negative phototropism can refer to either the growth away from a light source or towards the darkness. Most plant shoots exhibit positive phototropism, and rearrange their chloroplasts in the leaves to maximize photosynthetic energy and promote growth.Goyal, A., Szarzy ...

Plant Movements
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Closely related fields include plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, genetics, biophysics and molecular biology. Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied by plant physiologists. Aims The field of plant physiology includes the study of all the internal activities of plants—those chemical and physical processes associated with life as they occur in plants. This includes study at many levels of scale of size and time. At the smallest scale are molecular interactions of ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ralph Vaughan Williams
Ralph Vaughan Williams, (; 12 October 1872– 26 August 1958) was an English composer. His works include operas, ballets, chamber music, secular and religious vocal pieces and orchestral compositions including nine symphonies, written over sixty years. Strongly influenced by Tudor music and English folk-song, his output marked a decisive break in British music from its German-dominated style of the 19th century. Vaughan Williams was born to a well-to-do family with strong moral views and a progressive social life. Throughout his life he sought to be of service to his fellow citizens, and believed in making music as available as possible to everybody. He wrote many works for amateur and student performance. He was musically a late developer, not finding his true voice until his late thirties; his studies in 1907–1908 with the French composer Maurice Ravel helped him clarify the textures of his music and free it from Teutonic influences. Vaughan Williams is among the best ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knight Bachelor
The title of Knight Bachelor is the basic rank granted to a man who has been knighted by the monarch but not inducted as a member of one of the organised orders of chivalry; it is a part of the British honours system. Knights Bachelor are the most ancient sort of British knight (the rank existed during the 13th-century reign of King Henry III), but Knights Bachelor rank below knights of chivalric orders. A man who is knighted is formally addressed as " Sir irst Name urname or "Sir irst Name and his wife as "Lady urname. Criteria Knighthood is usually conferred for public service; amongst its recipients are all male judges of His Majesty's High Court of Justice in England. It is possible to be a Knight Bachelor and a junior member of an order of chivalry without being a knight of that order; this situation has become rather common, especially among those recognized for achievements in entertainment. For instance, Sir Michael Gambon, Sir Derek Jacobi, Sir Anthony Hopki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederic William Maitland
Frederic William Maitland (28 May 1850 – ) was an English historian and lawyer who is regarded as the modern father of English legal history. Early life and education, 1850–72 Frederic William Maitland was born at 53 Guilford Street, London, in 1850, the only son and second of three children of John Gorham Maitland and of Emma, daughter of John Frederic Daniell. His grandfather was Samuel Roffey Maitland. Maitland's father was a barrister but, having little practice, became a civil servant, serving as secretary to the Civil Service Commission. Maitland was educated at a preparatory school in Brighton before entering Eton College in 1863, where Edward Daniel Stone was his private tutor. At Eton, Maitland was not prominent either academically or athletically, although a close school friend thought he would become "a kind of philosophic Charles Lamb". He then matriculated at Trinity College, Cambridge, in 1869 as a commoner. A dislike of classics acquired at Eton initiall ...
