Conrad Dasypodius
Conrad Dasypodius (1532 – 26 April 1600) was a professor of mathematics in Strasbourg, Alsace. He was born in Frauenfeld, Thurgau, Switzerland. His first name was also rendered as Konrad or Conradus or Cunradus, and his last name has been alternatively stated as Rauchfuss, Rauchfuß, and Hasenfratz. He was the son of Petrus Dasypodius (Peter Hasenfuss) (1490–1559, or ''Peter Hasenfratz''), a humanist and lexicographer. In 1564, Dasypodius edited various parts of the ''Elements'' of Euclid. In the preface, he says that for 26 years it had been the rule at his school that all who were promoted from the classes to public lectures should learn Book I of the ''Elements'', but there were no longer any copies to be had so he was bringing out a new edition so as to maintain a good and fruitful regulation of his school. In 1568, Dasypodius published a work about the heliocentric theory of Nicolaus Copernicus, ''Hypotyposes orbium coelestium congruentes cum tabulis Alfonsinis ...

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Isaac Habrecht I
Isaac (1544–1620) and Josias (1552–1575) Habrecht were two clockmaker brothers from Schaffhausen, Switzerland. They were hired to build the second astronomical clock in Strasbourg between 1571 and 1574, its design being created by Christian Herlin and later his pupil Conrad Dasypodius. Josias and Isaac were two sons of the clockmaker Joachim Habrecht who built the astronomical clock in Schaffhausen. Joachim Habrecht Joachim has also built a clock in Solothurn. Isaac Habrecht Born 23 February 1544 in Schaffhausen, he died 11 November 1620 in Strasbourg. In 1566 he married Anna Rueger. In 1586 he married Margarete Beck. Josias Habrecht Brother of Isaac Habrecht. Cultural references * Habrecht is mentioned in Orson Welles' 1946 film '' The Stranger''. Mr. Wilson, played by Edward G. Robinson Edward G.

People From Alsace
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

16th-century Swiss Mathematicians
The 16th century begins with the Julian year 1501 ( MDI) and ends with either the Julian or the Gregorian year 1600 ( MDC) (depending on the reckoning used; the Gregorian calendar introduced a lapse of 10 days in October 1582). The 16th century is regarded by historians as the century which saw the rise of Western civilization and the Islamic gunpowder empires. The Renaissance in Italy and Europe saw the emergence of important artists, authors and scientists, and led to the foundation of important subjects which include accounting and political science. Copernicus proposed the heliocentric universe, which was met with strong resistance, and Tycho Brahe refuted the theory of celestial spheres through observational measurement of the 1572 appearance of a Milky Way supernova. These events directly challenged the long-held notion of an immutable universe supported by Ptolemy and Aristotle, and led to major revolutions in astronomy and science. Galileo Galilei became a champion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
