Otto Von Guericke
Otto von Guericke ( , , ; spelled Gericke until 1666; November 20, 1602 – May 11, 1686 ; November 30, 1602 – May 21, 1686 ) was a German scientist, inventor, and politician. His pioneering scientific work, the development of experimental methods and repeatable demonstrations on the physics of the vacuum, atmospheric pressure, electrostatic repulsion, his advocacy for the reality of " action at a distance" and of "absolute space" were noteworthy contributions for the advancement of the Scientific Revolution. Von Guericke was a very pious man in the Dionysian tradition and attributed the vacuum of space to the creations and designs of an infinite divinity. Von Guericke described this duality "as something that 'contains all things' and is 'more precious than gold, without beginning and end, more joyous than the perception of bountiful light' and 'comparable to the heavens'." Biography Early life and education Otto von Guericke was born to a patrician family of Magdeburg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anselm Van Hulle
Anselm van Hulle or Anselmus van Hulle (Gent, 1601 - 1674/1694) was a Flemish painter mainly of portraits whose works were highly prized at the Northern European Courts. He was court painter to the Prince of Orange and was one of the few portrait painters who attended the peace negotiations for the Peace of Münster in 1648. Van Hulle established an international reputation by having the portraits he made of the delegates at the negotiations engraved and published. Life Anselm van Hulle was baptized in the St. Bavo Church in Gent on 23 July 1601. He was the son of Egidius van Hulle.F. van den Bemden, ''Anselmus van Hulle, peintre gantois'', in Bulletin van de Maatschappij van Geschied- en Oudheidkunde te Gent, IX, 1901, pp. 42-46 He may have been a pupil of Gaspar de Crayer, a leading Baroque painter from Antwerp working mainly in Brussels. A training with such a prominent painter was relatively expensive. Van Hulle came from a wealthy family owning various lands and annui ...

Julian Calendar
The Julian calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on , by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria. The calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years until 1582, when Pope Gregory XIII promulgated a minor modification to reduce the average length of the year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the solar year. Worldwide adoption of this revised calendar, which became known as the Gregorian calendar, took place over the subsequent centuries, first in Catholic countries and subsequently in Protestant countries of the Western Christian world. The Julian calendar is still used in parts of the Eastern Orthodox Church and in parts of Oriental Orthodoxy as well as by the Berbers. The Julian calenda ...

Leiden University
Leiden University (abbreviated as ''LEI''; nl, Universiteit Leiden) is a public research university in Leiden, Netherlands. The university was founded as a Protestant university in 1575 by William, Prince of Orange, as a reward to the city of Leiden for its defence against Spanish attacks during the Eighty Years' War. As the oldest institution of higher education in the Netherlands, it enjoys a reputation across Europe and the world. Known for its historic foundations and emphasis on the social sciences, the university came into particular prominence during the Dutch Golden Age, when scholars from around Europe were attracted to the Dutch Republic due to its climate of intellectual tolerance and Leiden's international reputation. During this time, Leiden became the home to individuals such as René Descartes, Rembrandt, Christiaan Huygens, Hugo Grotius, Baruch Spinoza and Baron d'Holbach. The university has seven academic faculties and over fifty subject departments wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Jena
The University of Jena, officially the Friedrich Schiller University Jena (german: Friedrich-Schiller-Universität Jena, abbreviated FSU, shortened form ''Uni Jena''), is a public research university located in Jena, Thuringia, Germany. The university was established in 1558 and is counted among the ten oldest universities in Germany. It is affiliated with six Nobel Prize winners, most recently in 2000 when Jena graduate Herbert Kroemer won the Nobel Prize for physics.

University Of Helmstedt
The University of Helmstedt (german: Universität Helmstedt; official Latin name: ''Academia Julia'', "Julius University"), was a university in Helmstedt in the Duchy of Brunswick-Wolfenbüttel that existed from 1576 until 1810. History Founded by and named after Duke Julius of Brunswick-Wolfenbüttel on 15 October 1576, the first university of the duchy and the first Protestant university of the northern Holy Roman Empire quickly became one of the largest German universities. In order to train pastors and administrators for work in the Lutheran churches, the duchy needed a university of its own. In 1575, Julius obtained the Emperor's permission to open a university in Helmstedt. One year later the first lectures started. The princes of Wolfenbüttel held the office of the rector, starting with Julius' 12-year-old son John Henry. Tilemann Heshusius was an important early Lutheran theologian at Helmstedt. He developed a clergy network in the region that supported other Hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leipzig University
Leipzig University (german: Universität Leipzig), in Leipzig in Saxony, Germany, is one of the world's oldest universities and the second-oldest university (by consecutive years of existence) in Germany. The university was founded on 2 December 1409 by Frederick I, Elector of Saxony and his brother William II, Margrave of Meissen, and originally comprised the four scholastic faculties.

Landed Gentry
The landed gentry, or the ''gentry'', is a largely historical British social class of landowners who could live entirely from rental income, or at least had a country estate. While distinct from, and socially below, the British peerage, their economic base in land was often similar, and some of the landed gentry were wealthier than some peers. Many gentry were close relatives of peers, and it was not uncommon for gentry to marry into peerage. It is the British element of the wider European class of gentry. With or without noble title, owning rural land estates often brought with it the legal rights of lord of the manor, and the less formal name or title of ''squire'', in Scotland laird. Generally lands passed by primogeniture, and the inheritances of daughters and younger sons were in cash or stocks, and relatively small. Typically the gentry farmed some of their land, as well as exploiting timber, minerals such as coal, and owning mills and other sources of income, b ...

Apollonian And Dionysian
The Apollonian and the Dionysian are philosophical and literary concepts represented by a duality between the figures of Apollo and Dionysus from Greek mythology. Its popularization is widely attributed to the work ''The Birth of Tragedy'' by Friedrich Nietzsche, though the terms had already been in use prior to this, such as in the writings of poet Friedrich Hölderlin, historian Johann Joachim Winckelmann, and others. The word Dionysian occurs as early as 1608 in Edward Topsell's zoological treatise, ''The History of Serpents''. The concept has since been widely invoked and discussed within Western philosophy and literature. In Greek mythology, Apollo and Dionysus are both sons of Zeus. Apollo, son of Leto, is the god of the sun, of rational thinking and order, and appeals to logic, prudence and purity and stands for reason. Dionysus, son of Semele, is the god of wine and dance, of irrationality and chaos, representing passion, emotions and instincts. The anc ...

Scientific Revolution
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.Galilei, Galileo (1974) ''Two New Sciences'', trans.

Outer Space
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is . The plasma between galaxies is thought to account for about half of the baryonic (ordinary) matter in the universe, having a number density of less than one hydrogen atom per cubic metre and a kinetic temperature of millions of kelvins. Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces. Observa ...

Action At A Distance
In physics, action at a distance is the concept that an object can be affected without being physically touched (as in mechanical contact) by another object. That is, it is the non-local interaction of objects that are separated in space. Non-contact forces is action at a distance affecting specifically an object's motion. This term was used most often in the context of early theories of gravity and electromagnetism to describe how an object responds to the influence of distant objects. For example, Coulomb's law and Newton's law of universal gravitation are such early theories. More generally, "action at a distance" describes the failure of early atomistic and mechanistic theories which sought to reduce all physical interaction to collision. The exploration and resolution of this problematic phenomenon led to significant developments in physics, from the concept of a field, to descriptions of quantum entanglement and the mediator particles of the Standard Model.

Electrostatics
Electrostatics is a branch of physics that studies electric charges at rest ( static electricity). Since classical times, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, (), was thus the source of the word 'electricity'. Electrostatic phenomena arise from the forces that electric charges exert on each other. Such forces are described by Coulomb's law. Even though electrostatically induced forces seem to be rather weak, some electrostatic forces are relatively large. The force between an electron and a proton, which together make up a hydrogen atom, is about 36 orders of magnitude stronger than the gravitational force acting between them. There are many examples of electrostatic phenomena, from those as simple as the attraction of plastic wrap to one's hand after it is removed from a package, to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufac ...
