Johann Chrysostom Magnenus
Johann Chrysostom Magnenus (French ''Jean Chrysostôme Magnen'', c. 1590 – c. 1679) was a physician and advocate of atomism. He was born at Luxeuil in Burgundy. He took a medical degree at the University of Dôle. He joined the medical faculty at the University of Pavia, where he published his scientific work ''Democritus reviviscens'' in 1646. He cited Daniel Sennert, but his ideas were distinct from Sennert's and those of Democritus. He considered that atoms were the indivisible parts of three of the classical elements: earth, water and fire. In 1646, Magnenus estimated the number of atoms contained in a piece of incense from an argument based on the sense of smell (if a fraction of the grain is burned, the number of particles can be estimated from the volume within which the scent is still perceptible). His estimate for the number of particles in a piece of incense "not larger than a pea" was of the order of 1018. This estimate is remarkably accurate, within about ...

Atomism
Atomism (from Greek , ''atomon'', i.e. "uncuttable, indivisible") is a natural philosophy proposing that the physical universe is composed of fundamental indivisible components known as atoms. References to the concept of atomism and its atoms appeared in both ancient Greek and ancient Indian philosophical traditions. Leucippus is the earliest figure whose commitment to atomism is well attested and he is usually credited with inventing atomism. He and other ancient Greek atomists theorized that nature consists of two fundamental principles: ''atom'' and ''void''. Clusters of different shapes, arrangements, and positions give rise to the various macroscopic substances in the world.Berryman, Sylvia, "Ancient Atomism", ''The Stanford Encyclopedia of Philosophy'' (Fall 2008 Edition), Edward N. Zalta (ed.)online/ref> The particles of chemical matter for which chemists and other natural philosophers of the early 19th century found experimental evidence were thought to be indivisibl ...

Luxeuil
Luxeuil-les-Bains () is a commune in the Haute-Saône department in the region of Bourgogne-Franche-Comté in eastern France. History Luxeuil (sometimes rendered Luxeu in older texts) was the Roman Luxovium and contained many fine buildings at the time of its destruction by the Huns under Attila in 451. In 590, St Columban here founded the Abbey of Luxeuil, afterwards one of the most famous in Franche-Comté. In the 8th century, it was destroyed by the Saracens; afterwards rebuilt, monastery and town were devastated by the Normans, Magyars, and Muslims in the 9th century and pillaged on several occasions afterwards. The burning of the monastery and ravaging of the town are commonly used to illustrate the point that no place in Europe was safe during the invasions. The abbey schools were celebrated in the Middle Ages and the abbots had great influence; but their power was curtailed by the emperor Charles V and the abbey was suppressed at the time of the French Revolution.

County Of Burgundy
The Free County of Burgundy or Franche-Comté (french: Franche Comté de Bourgogne; german: Freigrafschaft Burgund) was a medieval county (from 982 to 1678) of the Holy Roman Empire, predecessor to the modern region of Franche-Comté. The name ' derives from the title of its count, ', in German 'free count', denoting imperial immediacy. It should not be confused with the more westerly Duchy of Burgundy, a fiefdom of France since 843. History The area once formed part of the Kingdom of the Burgundians, which had been annexed by the Franks in 534 and incorporated into the Kingdom of the Franks. The Empire was partitioned in 843 by the Treaty of Verdun, with the area west of the Saône river being allotted to West Francia as the French Duchy of Burgundy, while the southern and eastern parts of the former Burgundian kingdom fell to Middle Francia under Emperor Lothair I. This Middle Frankish part became the two independent entities of southern Lower Burgundy in 879 and northern Uppe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Dôle
The University of Dole was founded in 1423 by Philip the Good of Burgundy at Dole in the Free County of Burgundy (then a principality of the Holy Roman Empire, but now in France). It became a leading university in western Europe, historically notable for its teaching of canon and civil law. History From its foundation the university was student run, on the Bologna model, but in 1613 the college of professors sent a formal deputy to the archdukes in Brussels, seeking to convert the University to a ''Magisteruniversität'' such as Louvain and Douai. The archdukes issued edicts (1616-1618) with that intent, but the students would not have it, overtly repudiated the edicts, and boycotted the university.Mordechai Feingold (ed.), ''History of Universities'', vol. XVIII/2, (Oxford University Press, Oxford, 2003), pp. 41-42. It is probable that the edicts were never enforced. In 1691 Louis XIV, who had conquered the region in 1678, moved the university from Dole to Besançon where its s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Pavia
The University of Pavia ( it, Università degli Studi di Pavia, UNIPV or ''Università di Pavia''; la, Alma Ticinensis Universitas) is a university located in Pavia, Lombardy, Italy. There was evidence of teaching as early as 1361, making it one of the oldest universities in the world. It was the sole university in Milan and the greater Lombardy region until the end of the 19th century. In 2022 the University was recognized by the Times Higher Education among the top 10 in Italy and among the 300 best in the world. Currently, it has 18 departments and 9 faculties. It does not have a main campus; its buildings and facilities are scattered around the city, which is in turn called "a city campus." The university caters to more than 20,000 students who come from Italy and all over the world. The university offers more than 80 undergraduate programs; over 40 master programs, and roughly 20 doctoral programs (including 8 in English). About 1,500 students who enter the university every ...

Daniel Sennert
Daniel Sennert (25 November 1572 – 21 July 1637) was a renowned German physician and a prolific academic writer, especially in the field of alchemy or chemistry. He held the position of professor of medicine at the University of Wittenberg for many years. Biographical information Daniel Sennert was born in 1572 in the city of Breslau (now Wrocław, Poland), at the time part of the Habsburg monarchy. His father, Nicolaus Sennert, was a shoemaker from Laehn, Silesia. Sennert attended the University of Wittenberg and received his master's degree in 1598 and his medical degree in 1601. In his early work, he demonstrated an avoidance of alchemical theory and an acceptance of Aristotelian theory. However, within a decade of receiving his medical degree he had changed to accepting alchemical transmutation and experimentation as valid. He published a number of popular books on alchemy and chemistry, several of which received a number of reprintings and translations. He served on the ...

Classical Elements
Classical elements typically refer to earth, water, air, fire, and (later) aether which were proposed to explain the nature and complexity of all matter in terms of simpler substances. Ancient cultures in Greece, Tibet, and India had similar lists which sometimes referred, in local languages, to "air" as "wind" and the fifth element as "void". These different cultures and even individual philosophers had widely varying explanations concerning their attributes and how they related to observable phenomena as well as cosmology. Sometimes these theories overlapped with mythology and were personified in deities. Some of these interpretations included atomism (the idea of very small, indivisible portions of matter), but other interpretations considered the elements to be divisible into infinitely small pieces without changing their nature. While the classification of the material world in ancient Indian, Hellenistic Egypt, and ancient Greece into Air, Earth, Fire and Water was ...

Incense
Incense is aromatic biotic material that releases fragrant smoke when burnt. The term is used for either the material or the aroma. Incense is used for aesthetic reasons, religious worship, aromatherapy, meditation, and ceremony. It may also be used as a simple deodorant or insect repellent. Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing number of uses. Incense can generally be separated into two main types: "indirect-burning" and "direct-burning". Indirect-burning incense (or "non-combustible incense") is not capable of burning on its own, and requires a separate heat source. Direct-burning incense (or "combustible incense") is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Direct-burning incense is either a paste formed around a bamboo stic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
