1582 In Science
The year 1582 in science and technology included a number of events, some of which are listed here. This year sees the introduction of the Gregorian calendar, promulgated by Pope Gregory XIII in the Papal bull ''Inter gravissimas'' on February 24 and based largely on the work of Christopher Clavius. Under the Habsburg monarchy in Spain, Portugal and Italy, together with the Polish–Lithuanian Commonwealth, the year continues under the Julian calendar as normal until Thursday October 4, the next day becoming Friday October 15; France follows two months later, letting Sunday December 9 be followed by Monday December 20. Other countries switch in later years. Astronomy * Giovanni Antonio Magini publishes the ephemerides ''Ephemerides coelestium motuum''.

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 ...

Urbain Hémard
Urbain Hémard ( Entraygues, Aveyron circa 1548 - 14 October 1592 Estaing, Aveyron) was a French physician and dentist. He wrote the first French work entirely devoted to dentistry. Biography He studied at the University of Montpellier and settled around 1529 in Rodez where he served as lieutenant to the King's First Surgeon for his colleagues in the '' Sénéchaussée'' and the Diocese of Rouergue. He was one of the doctors of Rodez called in 1586 to the bedside of Margaret of Valois, who had taken refuge in the castle of Carlat after her rupture with her family and the King of Navarre, the future Henri IV. In 1589, he went to Aix-en-Provence, which was afflicted by the plague, and was congratulated by Antoine Davin, the King's physician. It was in Rodez that Bishop Georges d'Armagnac, ambassador of Francis I in Venice, suffering from dental pains called upon him. Hémard remained for ten years in the service of the Cardinal of Armagnac. In 1582, Hémard dedicated his book '' ... [...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 ...

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 ...

Jacques Peletier Du Mans
Jacques Pelletier du Mans, also spelled Peletier ( la, Iacobus Peletarius Cenomani, 25 July 1517 – 17 July 1582) was a humanist, poet and mathematician of the French Renaissance. Born in Le Mans into a bourgeois family, he studied at the Collège de Navarre in Paris, where his brother Jean was a professor of mathematics and philosophy. He subsequently studied law and medicine, frequented the literary circle around Marguerite de Navarre and from 1541 to 1543 he was secretary to René du Bellay. In 1541 he published the first French translation of Horace's '' Ars Poetica'' and during this period he also published numerous scientific and mathematical treatises. In 1547 he produced a funeral oration for Henry VIII of England and published his first poems (''Œuvres poétiques''), which included translations from the first two cantos of Homer's ''Odyssey'' and the first book of Virgil's ''Georgics'', twelve Petrarchian sonnets, three Horacian odes and a Martial-like epigram; t ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Giovanni Battista Baliani
Giovanni Battista Baliani (1582–1666) was an Italian mathematician, physicist and astronomer. Career He was born in Genoa. He was governor of Savona in 1647–1649 and captain of the Republic of Genoa's archers. For some 25 years, he held a correspondence with Galileo Galilei about the time's most innovative scientific theories and experiments.. However, Applebaum also calls Baliani's correspondence with Galileo "intermittent". For another discussion of the timing and content of letters dating from 1615 to 1639, see . Work At Savona, from the Priamar Fortress, he repeated Galileo's experiment of the Tower of Pisa, obtaining more precise measurements which allowed him to underline the effect of air attrition. He also conducted an experiment to show the heat generated by a pot full of water, which he had boiled after rotating it at high speed. His main work is entitled ''De motu naturali gravium, fluidorum et solidorum'' ("About the motion of bodies, fluids and solids"), publis ...

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 ...

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.
