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 ...

Ludolph Van Ceulen
Ludolph van Ceulen (, ; 28 January 1540 – 31 December 1610) was a German-Dutch mathematician from Hildesheim. He emigrated to the Netherlands. Biography Van Ceulen moved to Delft most likely in 1576 to teach fencing and mathematics and in 1594 opened a fencing school in Leiden. In 1600 he was appointed the first professor of mathematics at the Engineering School, Duytsche Mathematique, established by Maurice, Prince of Orange, at the relatively new Leiden University. He shared this professorial level at the school with the surveyor and cartographer, , which shows that the intention was to promote practical, rather than theoretical instruction. The curriculum for the new Engineering School was devised by Simon Stevin who continued to act as the personal advisor to the Prince. At first the professors at Leiden refused to accept the status of Van Ceulen and Van Merwen, especially as they taught in Dutch rather than Latin. Theological professors generally believed that practica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Of Aegina
Paul of Aegina or Paulus Aegineta ( el, Παῦλος Αἰγινήτης; Aegina, ) was a 7th-century Byzantine Greek physician best known for writing the medical encyclopedia ''Medical Compendium in Seven Books.'' He is considered the “Father of Early Medical Writing”. For many years in the Byzantine Empire, his works contained the sum of all Western medical knowledge and was unrivaled in its accuracy and completeness. Life Nothing is known about his life, except that he was born in the island of Aegina, and that he travelled a good deal, visiting, among other places, Alexandria. He is sometimes called ''Iatrosophistes'' and ''Periodeutes'', a word which probably means a physician who travelled from place to place in the exercise of his profession. The exact time when he lived is not known; but, as he quotes Alexander of Tralles, and is himself quoted by Yahya ibn Sarafyun (''Serapion the Elder''), it is probable that Abu-al-Faraj is correct in placing him in the latter half ...

Pierre Tolet
Pierre Tolet or Petrus Toletus (circa 1502 - circa 1580) was a French physician who, together with Jean Canappe contributed to the transmission of medical and surgical knowledge in French. Biography Originally from the diocese of Béziers, he studied medicine at the Faculty of Montpellier under Jean Schyron. He graduated in 1529 along with Nostradamus, Jacobus Sylvius and Guillaume Rondelet. He practised in Vienne, Bourg and then in Lyon where he became a physician at the Hôtel-Dieu. As Dean of the Faculty of Lyon, he introduced a French-language teaching programme with daily visits by students to the hospital and created a single training course for physicians, barbers surgeons and apothecaries.

Eucharius Rösslin
Eucharius Rösslin (Roslin, Rößlin), sometimes known as Eucharius Rhodion, (c. 1470 – 1526) was a German physician who in 1513 authored a book about childbirth called ''Der Rosengarten'' (The Rose Garden), which became a standard medical text for midwife, midwives. Midwifery Rösslin was an apothecary at Freiburg before being elected physician to the city of Frankfurt on Main in 1506. He served as physician to the city of Worms, Germany, Worms in the service of Catherine of Pomerania-Wolgast, Katherine, wife of Henry IV, Duke of Brunswick-Lüneburg. While examining and supervising the city's midwives, he found their practice of midwifery to be careless and substandard, leading to high rates of infant mortality. As a result, he wrote his book in German, to make it accessible, and published it in the then-German city of Strasbourg. He included in it engravings by Martin Caldenbach, a pupil of Albrecht Dürer. Thereby ''Der Rosengarten'' gave for the first time printed illust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

De La Pirotechnia
''De la Pirotechnia'' is considered to be one of the first printed books on metallurgy to have been published in Europe. It was written in Italian and first published in Venice in 1540. The author was Vannoccio Biringuccio, a citizen of Siena, Italy, who died before it was published. Further editions were published in 1550, 1558, 1559, and 1678, with a (sloppy) French translation by Jacques Vincent being published in 1556, 1572, and 1627. Parts were translated into Latin (by Georgius Agricola), English ( Richard Eden; Peter Whitehorn) and Spanish (Bernardo Perez de Vargas) at various times in the 1550s and 1560s, generally without acknowledgement. The second book on metallurgy, '' De re metallica'', was written in Latin by Georgius Agricola, and published in 1556. Mining was typically left to professionals, craftsmen and experts who were not eager to share their knowledge. Much experiential knowledge had been accumulated over the course of time. This knowledge was consecutive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
