Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Inventor
An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see human computers). Some inventions can be patented. The system of patents was established ... [...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] |
French People
The French people (french: Français) are an ethnic group and nation primarily located in Western Europe that share a common French culture, history, and language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily the descendants of Gauls (including the Belgae) and Romans (or Gallo-Romans, western European Celtic and Italic peoples), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norse also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such as Bretons in Brittany, Occi ...

François Boissier De Sauvages De Lacroix
François Boissier de Sauvages de Lacroix (May 12, 1706 – February 19, 1767) was a French physician and botanist who was a native of Alès. He was the brother of naturalist Pierre Augustin Boissier de Sauvages (1710—1795). He received his education at the University of Montpellier, where he studied botany with Pierre Baux (1708-1790). After spending a few years in Paris, he returned to Montpellier in 1734, where he served as a professor of physiology and pathology. Following the death of François Ayme Chicoyneau (1702-1740), he was named to the chair of botany. At Montpellier, he made important improvements to its botanical garden, which included construction of its first greenhouse. He was a friend to Swedish naturalist Carl von Linné (1707—1778), to whom Sauvages de Lacroix sent botanical specimens from the Montpellier region for study. Linné designated the botanical genus ''Sauvagesia'' in honor of his French colleague. In 1748 he was elected a member of the Royal Swe ...

Pediatrician
Pediatrics ( also spelled ''paediatrics'' or ''pædiatrics'') is the branch of medicine that involves the medical care of infants, children, adolescents, and young adults. In the United Kingdom, paediatrics covers many of their youth until the age of 18. The American Academy of Pediatrics recommends people seek pediatric care through the age of 21, but some pediatric subspecialists continue to care for adults up to 25. Worldwide age limits of pediatrics have been trending upward year after year. A medical doctor who specializes in this area is known as a pediatrician, or paediatrician. The word ''pediatrics'' and its cognates mean "healer of children," derived from the two Greek words: (''pais'' "child") and (''iatros'' "doctor, healer"). Pediatricians work in clinics, research centers, universities, general hospitals and children's hospitals, including those who practice pediatric subspecialties (e.g. neonatology requires resources available in a NICU).

Swedes
Swedes ( sv, svenskar) are a North Germanic ethnic group native to the Nordic region, primarily their nation state of Sweden, who share a common ancestry, culture, history and language. They mostly inhabit Sweden and the other Nordic countries, in particular Finland where they are an officially recognized minority, with a substantial diaspora in other countries, especially the United States. Etymology The English term "Swede" has been attested in English since the late 16th century and is of Middle Dutch or Middle Low German origin. In Swedish, the term is ''svensk'', which is from the name of '' svear'' (or Swedes), the people who inhabited Svealand in eastern central Sweden, and were listed as ''Suiones'' in Tacitus' history '' Germania'' from the first century AD. The term is believed to have been derived from the Proto-Indo-European reflexive pronominal root, , as the Latin ''suus''. The word must have meant "one's own (tribesmen)". The same root and original mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nils Rosén Von Rosenstein
Nils Rosén von Rosenstein (11 February 1706 – 16 July 1773) was a Swedish physician. He is considered the founder of modern pediatrics, while his work ''The diseases of children, and their remedies'' is considered to be "the first modern textbook on the subject". Career Nils Rosén was born in Sexdrega, Västra Götaland County in 1706. Son of the vicar Erich Rosenius and of Anna Wekander, he studied at the Gymnasium of Gothenburg and when he was 16 years old at Lund University under Kilian Stobaeus, and in Uppsala. In 1727, he was appointed as a lecturer at the Uppsala University, replacing Petrus Martin who had recently died. Rosén had already worked as an assistant to professor Olof Rudbeck at the time. But he couldn't take up this position until 1731, spending those four years traveling and studying abroad in Germany, Italy, France, and the Netherlands, where he studied for a while under Friedrich Hoffmann, Herman Boerhaave and Pieter van Musschenbroek. He stayed for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
