Clarinet
The clarinet is a musical instrument in the woodwind family. The instrument has a nearly cylindrical bore and a flared bell, and uses a single reed to produce sound. Clarinets comprise a family of instruments of differing sizes and pitches. The clarinet family is the largest such woodwind family, with more than a dozen types, ranging from the BB♭ contrabass to the E♭ soprano. The most common clarinet is the B soprano clarinet. German instrument maker Johann Christoph Denner is generally credited with inventing the clarinet sometime after 1698 by adding a register key to the chalumeau, an earlier single-reed instrument. Over time, additional keywork and the development of airtight pads were added to improve the tone and playability. Today the clarinet is used in classical music, military bands, klezmer, jazz, and other styles. It is a standard fixture of the orchestra and concert band. Etymology The word ''clarinet'' may have entered the English language via the Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Gerard Van Swieten
Gerard van Swieten (7 May 1700 – 18 June 1772) was a Dutch physician who from 1745 was the personal physician of the Holy Roman Empress Maria Theresa and transformed the Austrian health service and medical university education. He was the father of Gottfried van Swieten, patron of Haydn, Mozart and Beethoven. Youth and study Gerard van Swieten was the one surviving child of a prominent Catholic family in Leiden. His parents, the notary Thomas van Swieten (1662–1712) and Elisabeth Loo (†1708), had their children baptized by Jesuit priests, and Van Swieten remained a Roman Catholic throughout his life. His paternal family had been prominent Leiden citizens since the 15th century, carrying a coat of arms with three violins, which Van Swieten modified and adopted when he was made a Baron in 1753. They potentially descended from the old but already extinct noble house of , from the castle Zwieten, though there is no direct evidence for this. Van Swieten was a precocious stude ...

Biology * Jesuit abbot Juan Ignacio Molina publishes ''Saggio sulla Storia Naturale del Chili'' in Spain, the first account of the natural history of his native Chile, describing many species to science for the first time (e.g., ''Araucaria araucana''). Chemistry * Telluride minerals are first discovered in a gold mine in Zlatna, Kleinschlatten, Transylvania (modern-day Zlatna, Romania) by Austrians, Austrian Mineralogy, mineralogist Franz-Joseph Müller von Reichenstein. * Winter 1782–83 – Antoine Lavoisier and Pierre-Simon Laplace begin to use the world's first ice calorimeter to determine the heat evolved in various chemical changes (calculations based on Joseph Black's prior discovery of latent heat), marking the foundation of thermochemistry. Medicine * September – Notting ... [...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 ...

Daniel Bernoulli
Daniel Bernoulli FRS (; – 27 March 1782) was a Swiss mathematician and physicist and was one of the many prominent mathematicians in the Bernoulli family from Basel. He is particularly remembered for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability and statistics. His name is commemorated in the Bernoulli's principle, a particular example of the conservation of energy, which describes the mathematics of the mechanism underlying the operation of two important technologies of the 20th century: the carburetor and the airplane wing. Early life Daniel Bernoulli was born in Groningen, in the Netherlands, into a family of distinguished mathematicians. Rothbard, MurrayDaniel Bernoulli and the Founding of Mathematical Economics ''Mises Institute'' (excerpted from ''An Austrian Perspective on the History of Economic Thought'') The Bernoulli family came originally from Antwerp, at that time in the Spanish Netherlands, ...

Gottfried Leibniz
Gottfried Wilhelm (von) Leibniz . ( – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat. He is one of the most prominent figures in both the history of philosophy and the history of mathematics. He wrote works on philosophy, theology, ethics, politics, law, history and philology. Leibniz also made major contributions to physics and technology, and anticipated notions that surfaced much later in probability theory, biology, medicine, geology, psychology, linguistics and computer science. In addition, he contributed to the field of library science: while serving as overseer of the Wolfenbüttel library in Germany, he devised a cataloging system that would have served as a guide for many of Europe's largest libraries. Leibniz's contributions to this vast array of subjects were scattered in various learned journals, in tens of thousands of letters and in unpublished manuscripts. He wrote in several languages, primarily in Latin, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prussian Academy Of Sciences
The Royal Prussian Academy of Sciences (german: Königlich-Preußische Akademie der Wissenschaften) was an academy established in Berlin, Germany on 11 July 1700, four years after the Prussian Academy of Arts, or "Arts Academy," to which "Berlin Academy" may also refer. In the 18th century, it was a French-language institution since French was the language of science and culture during that era. Origins Prince-elector Frederick III of Brandenburg, Germany founded the Academy under the name of ''Kurfürstlich Brandenburgische Societät der Wissenschaften'' ("Electoral Brandenburg Society of Sciences") upon the advice of Gottfried Wilhelm Leibniz, who was appointed president. Unlike other Academies, the Prussian Academy was not directly funded out of the state treasury. Frederick granted it the monopoly on producing and selling calendars in Brandenburg, a suggestion from Leibniz. As Frederick was crowned "King in Prussia" in 1701, creating the Kingdom of Prussia, the Academy was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medici
The House of Medici ( , ) was an Italian banking family and political dynasty that first began to gather prominence under Cosimo de' Medici, in the Republic of Florence during the first half of the 15th century. The family originated in the Mugello region of Tuscany, and prospered gradually until it was able to fund the Medici Bank. This bank was the largest in Europe during the 15th century and facilitated the Medicis' rise to political power in Florence, although they officially remained citizens rather than monarchs until the 16th century. The Medici produced four popes of the Catholic Church—Pope Leo X (1513–1521), Pope Clement VII (1523–1534), Pope Pius IV (1559–1565) and Pope Leo XI (1605)—and two queens of France—Catherine de' Medici (1547–1559) and Marie de' Medici (1600–1610). In 1532, the family acquired the hereditary title Duke of Florence. In 1569, the duchy was elevated to the Grand Duchy of Tuscany after territorial expansion. The Medici ruled the G ...

Bartolomeo Cristofori
Bartolomeo Cristofori di Francesco (; May 4, 1655 – January 27, 1731) was an Italian maker of musical instruments famous for inventing the piano. Life The available source materials on Cristofori's life include his birth and death records, two wills, the bills he submitted to his employers, and a single interview carried out by Scipione Maffei. From the latter, both Maffei's notes and the published journal article are preserved. Cristofori was born in Padua in the Republic of Venice. Nothing is known of his early life. A tale is told that he served as an apprentice to the great violin maker Nicolò Amati, based on the appearance in a 1680 census record of a "Christofaro Bartolomei" living in Amati's house in Cremona. However, as Stewart Pollens points out, this person cannot be Bartolomeo Cristofori, since the census records an age of 13, whereas Cristofori according to his baptismal record would have been 25 at the time. Pollens also gives strong reasons to doubt the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
