Nicolas Lemery
Nicolas Lémery (or Lemery as his name appeared in his international publications) (17 November 1645 – 19 June 1715), French chemist, was born at Rouen. He was one of the first to develop theories on acid-base chemistry. Life After learning pharmacy in his native town he became a pupil of Christophe Glaser in Paris, and then went to Montpellier, where he began to lecture on chemistry. He next established a pharmacy in Paris, still continuing his lectures, but following 1683, being a Calvinist, he was obliged to retire to England. In the following year he returned to France, and turning Catholic in 1686 was able to reopen his shop and resume his lectures. He died in Paris on 19 June 1715. Lemery did not concern himself much with theoretical speculations, but holding chemistry to be a demonstrative science, confined himself to the straightforward exposition of facts and experiments. In consequence, his lecture-room was thronged with people of all sorts, anxious to hear a man w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rouen
Rouen (, ; or ) is a city on the River Seine, in northwestern France. It is in the prefecture of Regions of France, region of Normandy (administrative region), Normandy and the Departments of France, department of Seine-Maritime. Formerly one of the largest and most prosperous cities of medieval Europe, the population of the metropolitan area () is 702,945 (2018). People from Rouen are known as ''Rouennais''. Rouen was the seat of the Exchequer of Normandy during the Middle Ages. It was one of the capitals of the Anglo-Normans, Anglo-Norman and Angevin kings of England, Angevin dynasties, which ruled both England and large parts of modern France from the 11th to the 15th centuries. From the 13th century onwards, the city experienced a remarkable economic boom, thanks in particular to the development of textile factories and river trade. Claimed by both the French and the English during the Hundred Years' War, it was on its soil that Joan of Arc was tried and burned alive on 30 ...

University And State Library Düsseldorf
The University and State Library Düsseldorf (, abbreviated ULB Düsseldorf) is a central service institution of Heinrich Heine University. Along with Bonn and Münster, it is also one of the three State Libraries of North Rhine-Westphalia. Tradition and Modernity From 1965 to 1969, the University and Library Düsseldorf gradually developed out of the Medical Academy in Düsseldorf. There is no real founding year of the ULB, but the foundation stone for an integrated library system was laid when the former State and City Library of Düsseldorf was taken over by the university in 1970 and merged with the Central Library of the former Medical Academy. Structure and Holdings The ULB consists of one central library and four decentralized locations. Management and media processing are organized centrally. Catalogues, databases, e-books and e-journals are accessible throughout the whole university as well as at home via the library network. Collections Thomas Mann Collection ...

Jardin Des Plantes
The Jardin des Plantes (, ), also known as the Jardin des Plantes de Paris () when distinguished from other ''jardins des plantes'' in other cities, is the main botanical garden in France. Jardin des Plantes is the official name in the present day, but it is in fact an elliptical form of Jardin Royal des Plantes Médicinales ("Royal Garden of the Medicinal Plants"), which is related to the original purpose of the garden back in the 17th century. Headquarters of the Muséum National d'Histoire Naturelle (National Museum of Natural History, part of Sorbonne University), the Jardin des Plantes is situated in the 5th arrondissement, Paris, on the left bank of the river Seine, and covers 28 hectares (280,000 m2). Since 24 March 1993, the entire garden and its contained buildings, archives, libraries, greenhouses, '' ménagerie'' (a zoo), works of art, and specimens' collection are classified as a national historical landmark in France (labelled ''monument historique'').

Hôtel-Dieu De Paris
In French-speaking countries, a hôtel-Dieu () was originally a hospital for the poor and needy, run by the Catholic Church. Nowadays these buildings or institutions have either kept their function as a hospital, the one in Paris being the oldest and most renowned, or have been converted into hotels, museums, or general purpose buildings (for instance housing a préfecture, the administrative head office of a French department). Therefore, as a secondary meaning, the term hôtel-Dieu can also refer to the building itself, even if it no longer houses a hospital. Examples include: ;Belgium * Notre Dame à la Rose, founded in 1242 ;France *Hôtel-Dieu d'Angers, founded in 1153 * Hôtel-Dieu de Beaune, founded in 1443 * Hôtel-Dieu of Carpentras, built in 1754 *Hôtel-Dieu of Château-Thierry, founded in 1304 *Hôtel-Dieu of Cluny, built in the 17th and 18th century * Hôtel-Dieu de Lyon, created in 1478 *Hôtel-Dieu of Nantes Nantes (, ; ; or ; ) is a city in the Loire-Atla ...

Louis Lémery
Louis Lémery (25 January 1677 – 9 June 1743) was a French botanist and chemist. The son of scientist Nicolas Lemery, Louis was appointed physician at the Hôtel-Dieu de Paris in 1710, and became demonstrator of chemistry at the Jardin du Roi in 1731.

Sulfur
Sulfur ( American spelling and the preferred IUPAC name) or sulphur ( Commonwealth spelling) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most common on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere Th ...

Lightning
Lightning is a natural phenomenon consisting of electrostatic discharges occurring through the atmosphere between two electrically charged regions. One or both regions are within the atmosphere, with the second region sometimes occurring on the land, ground. Following the lightning, the regions become partially or wholly electrically neutralized. Lightning involves a near-instantaneous release of energy on a scale averaging between 200 megajoules and 7 gigajoules. The air around the lightning flash rapidly heats to temperatures of about . There is an emission of electromagnetic radiation across a wide range of wavelengths, some visible as a bright flash. Lightning also causes thunder, a sound from the shock wave which develops as heated gases in the vicinity of the discharge experience a sudden increase in pressure. The most common occurrence of a lightning event is known as a thunderstorm, though they can also commonly occur in other types of energetic weather systems, such ...

Earthquake
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
