Scottish People
The Scots ( sco, Scots Fowk; gd, Albannaich) are an ethnic group and nation native to Scotland. Historically, they emerged in the early Middle Ages from an amalgamation of two Celtic-speaking peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or ''Alba'') in the 9th century. In the following two centuries, the Celtic-speaking Cumbrians of Strathclyde and the Germanic-speaking Angles of north Northumbria became part of Scotland. In the High Middle Ages, during the 12th-century Davidian Revolution, small numbers of Norman nobles migrated to the Lowlands. In the 13th century, the Norse-Gaels of the Western Isles became part of Scotland, followed by the Norse of the Northern Isles in the 15th century. In modern usage, "Scottish people" or "Scots" refers to anyone whose linguistic, cultural, family ancestral or genetic origins are from Scotland. The Latin word ''Scoti'' originally referred to the Gaels, but came to describe all inhabitants of Scotland. Cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Physician
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Hope (botanist)
Professor John Hope (10 May 1725 – 10 November 1786) was a Scottish physician and botanist. Although he did enormous work on plant classification and plant physiology, due to an absence of publications, he is now best known as an early supporter of Carl Linnaeus's system of classification. In 1783 he was a joint founder of the Royal Society of Edinburgh. In 1784 Hope was elected as president of the Royal College of Physicians of Edinburgh (1784-6). Early life Born in Edinburgh on 10 May 1725, John Hope was the son of surgeon Robert Hope and Marion Glas, and a grandson of Archibald Hope, Lord Rankeillor, a Senator of the College of Justice who was in turn the son of Sir John Hope, 2nd Baronet. He was the great-grandson of Sir Thomas Hope, 1st Baronet. He was educated at Dalkeith Grammar School, then studied medicine at the University of Edinburgh. He took leave to study botany under Bernard de Jussieu at the University of Paris, but returned to his studies in Scotland, gr ...

Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of intera ...

English People
The English people are an ethnic group and nation native to England, who speak the English language in England, English language, a West Germanic languages, West Germanic language, and share a common history and culture. The English identity is of History of Anglo-Saxon England, Anglo-Saxon origin, when they were known in Old English as the ('race or tribe of the Angles'). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. The English largely descend from two main historical population groups the West Germanic tribes (the Angles, Saxons, Jutes and Frisians) who settled in southern Britain following the withdrawal of the Ancient Rome, Romans, and the Romano-British culture, partially Romanised Celtic Britons already living there.Martiniano, R., Caffell, A., Holst, M. et al.

Dru Drury
Dru Drury (4 February 1724 – 15 December 1803) was a British collector of natural history specimens and an entomologist. He had specimens collected from across the world through a network of ship's officers and collectors including Henry Smeathman. His collections were utilized by many entomologists of his time to describe and name new species and is best known for his book ''Illustrations of natural history'' which includes the names and descriptions of many insects, published in parts from 1770 to 1782 with copperplate engravings by Moses Harris. Life Dru Drury was born in Lad Lane, Wood Street, London where his father, also Dru [also given as "Drew"] Drury (1688–1763), was a Freedom of the City of London, citizen, goldsmith and silversmith of the City of London, and his second wife Mary, daughter of Dr Hesketh, chaplain to Anne, Queen of Great Britain, Queen Anne.

Louis-Bertrand Castel
Louis Bertrand Castel (5 November 1688 – 11 January 1757) was a French mathematician born in Montpellier, who entered the order of the Jesuits in 1703. Having studied literature, he afterwards devoted himself entirely to mathematics and natural philosophy. After moving from Toulouse to Paris in 1720, at the behest of Bernard de Fontenelle, Castel acted as the science editor of the Jesuit ''Journal de Trévoux''. He wrote several scientific works, that which attracted most attention at the time being his ''Optique des couleurs'' (1740), or treatise on the melody of colours.

Harpsichord
A harpsichord ( it, clavicembalo; french: clavecin; german: Cembalo; es, clavecín; pt, cravo; nl, klavecimbel; pl, klawesyn) is a musical instrument played by means of a keyboard. This activates a row of levers that turn a trigger mechanism that plucks one or more strings with a small plectrum made from quill or plastic. The strings are under tension on a soundboard, which is mounted in a wooden case; the soundboard amplifies the vibrations from the strings so that the listeners can hear it. Like a pipe organ, a harpsichord may have more than one keyboard manual, and even a pedal board. Harpsichords may also have stop buttons which add or remove additional octaves. Some harpsichords may have a buff stop, which brings a strip of buff leather or other material in contact with the strings, muting their sound to simulate the sound of a plucked lute. The term denotes the whole family of similar plucked-keyboard instruments, including the smaller virginals, muselar, and spinet. ...
