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 ...

Frederick William Hope
Frederick William Hope (3 January 1797 – 15 April 1862) was an English clergyman, naturalist, collector, and entomologist, who founded a professorship at the University of Oxford to which he gave his entire collections of insects in 1849 (now known as the Hope Collection or in expanded form the Hope Entomological Collections, with around 3.5 million specimens). He described numerous species and was a founder of the Entomological Society of London in 1833 along with John Obadiah Westwood. Biography Frederick was the second son of John Thomas Hope of Netley Hall, Shrewsbury, and Ellen Hester Mary, only child and heiress of Sir Thomas Edwardes, and was born at their home in 37 Upper Seymour Street, London. He studied under the private tutor Reverend Delafosse and joined Christ Church, Oxford in 1817 and graduated with a BA in 1820. Presented to the curacy of Frodesley in Shropshire, he quickly retired as a result of ill health. Hope married, in 1835, the wealthy Ellen Meredith, ...

Psychiatrist
A psychiatrist is a physician who specializes in psychiatry, the branch of medicine devoted to the diagnosis, prevention, study, and treatment of mental disorders. Psychiatrists are physicians and evaluate patients to determine whether their symptoms are the result of a physical illness, a combination of physical and mental ailments or strictly mental issues. Sometimes a psychiatrist works within a multi-disciplinary team, which may comprise Clinical psychology, clinical psychologists, Social work, social workers, Occupational therapist, occupational therapists, and Nursing, nursing staff. Psychiatrists have broad training in a Biopsychosocial model, biopsychosocial approach to the assessment and management of mental illness. As part of the clinical assessment process, psychiatrists may employ a mental status examination; a physical examination; brain imaging such as a computerized tomography, magnetic resonance imaging, or positron emission tomography scan; and blood testing.

Flemish People
The Flemish or Flemings ( nl, Vlamingen ) are a Germanic ethnic group native to Flanders, Belgium, who speak Dutch. Flemish people make up the majority of Belgians, at about 60%. "''Flemish''" was historically a geographical term, as all inhabitants of the medieval County of Flanders in modern-day Belgium, France, and the Netherlands were referred to as "Flemings", irrespective of their ethnicity or language. The contemporary region of Flanders comprises a part of this historical county, as well as parts of the medieval duchy of Brabant and the medieval county of Loon, where the modern national identity and culture gradually formed. History The sense of "Flemish" identity increased significantly after the Belgian Revolution. Prior to this, the term "Vlamingen" in the Dutch language was in first place used for the inhabitants of the former County of Flanders. Flemish, however, had been used since the 14th century to refer to the language and dialects of both the peoples of Fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Guislain
Joseph Guislain (Ghent, 2 February 1797 – Ghent, 1 April 1860) was a Belgian physician and a pioneer in psychiatry. Education Guislain started his medical studies at Ecole de Médicine and he was one of the first students to the University of Ghent; he graduated as a medical doctor in 1819. Career In 1828 Guislain became head of the psychiatric hospitals of Ghent, for which he wrote a new internal regulation together with Petrus Josef Triest. It was the first of its type and stipulated how to handle the patients in a decent and therapeutically justified way. In 1850, together with Edouard Ducpétiaux, he was at the basis of the law on psychiatric care, which would remain the framework for psychiatric care in Belgium until 1991. Joseph Guislain published his ''Traité sur les phrénopathies'' in 1833, in which he proposed a new form of psychiatric classification. He argued that although mental illnesses could take many forms they were all derived from the same single disease pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Joseph Adhemar
Joseph is a common male given name, derived from the Hebrew Yosef (יוֹסֵף). "Joseph" is used, along with "Josef", mostly in English, French and partially German languages. This spelling is also found as a variant in the languages of the modern-day Nordic countries. In Portuguese and Spanish, the name is "José". In Arabic, including in the Quran, the name is spelled ''Yūsuf''. In Persian, the name is "Yousef". The name has enjoyed significant popularity in its many forms in numerous countries, and ''Joseph'' was one of the two names, along with ''Robert'', to have remained in the top 10 boys' names list in the US from 1925 to 1972. It is especially common in contemporary Israel, as either "Yossi" or "Yossef", and in Italy, where the name "Giuseppe" was the most common male name in the 20th century. In the first century CE, Joseph was the second most popular male name for Palestine Jews. In the Book of Genesis Joseph is Jacob's eleventh son and Rachel's first son, and kn ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Prussia
Prussia, , Old Prussian: ''Prūsa'' or ''Prūsija'' was a German state on the southeast coast of the Baltic Sea. It formed the German Empire under Prussian rule when it united the German states in 1871. It was ''de facto'' dissolved by an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and ''de jure'' by an Allied decree in 1947. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army. Prussia, with its capital at Königsberg and then, when it became the Kingdom of Prussia in 1701, Berlin, decisively shaped the history of Germany. In 1871, Prussian Minister-President Otto von Bismarck united most German principalities into the German Empire under his leadership, although this was considered to be a "Lesser Germany" because Austria and Switzerland were not included. In November 1918, the monarchies were abolished and the nobility lost its political power during the Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Beer
Wilhelm Wolff Beer (4 January 1797 – 27 March 1850) was a banker and astronomer from Berlin, Prussia, and the brother of Giacomo Meyerbeer. Astronomy Beer's fame derives from his hobby, astronomy. He built a private observatory with a 9.5 cm refractor in Tiergarten, Berlin. Together with Johann Heinrich Mädler he produced the first exact map of the Moon (entitled '' Mappa Selenographica'') in 1834-1836, and in 1837 published a description of the Moon (''Der Mond nach seinen kosmischen und individuellen Verhältnissen''). Both remained the best descriptions of the Moon for many decades. In 1830, Beer and Mädler created the first globe of the planet Mars. In 1840 they made a map of Mars and calculated its rotation period to be 24 h 37 min 22.7 s, only 0.1 seconds different from the actual period as it is known today. Other work In addition to his hobby of astronomy, he helped with the establishment of a railway system in Prussia, and promoted the Jewish community ...
