Logroño
Logroño () is the capital of the province of La Rioja, situated in northern Spain. Traversed in its northern part by the Ebro River, Logroño has historically been a place of passage, such as the Camino de Santiago. Its borders were disputed between the Iberian kingdoms of Castille, Navarre and Aragon during the Middle Ages. The population of the city in 2021 was 150,808 while the metropolitan area included nearly 200,000 inhabitants. The city is a centre of trade of Rioja wine, for which the area is noted, and manufacturing of wood, metal and textile products. Etymology Origin of the name The origin of this toponym is, as for many other places, unknown. The name ''Lucronio'' was first used in a document from 965 where García Sánchez I of Pamplona donated the so-called place to the Monastery of San Millán. In the fuero from 1095 it appeared under the name ''Logronio'', except once when it was called ''illo Gronio''. The most broadly accepted theses seem to be those ...

Fausto Elhuyar
Fausto de Elhuyar (11 October 1755 – 6 February 1833) was a Spanish chemist, and the first to isolate tungsten with his brother Juan José Elhuyar in 1783. He was in charge, under a King of Spain commission, of organizing the School of Mines in México City and so was responsible for building an architectural jewel known as the "Palacio de Minería". Elhuyar left Mexico after the Mexican War of Independence, when most of the Spanish residents in Mexico were expelled. Life He was born in Logroño, La Rioja, Spain son of Basque-French parents from Hasparren, France. Between 1773 and 1777, Elhúyar studied medicine, surgery and chemistry, as well as mathematics, physics and natural history with his brother Juan José Elhuyar in Paris. After graduating, he returned to Spain, where he exercised himself in the study of mineralogy, specially that of the Basque Country and Navarre, where he resided. In 1781, he was appointed a member of the ''Real Sociedad Bascongada de Amigos del P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discoverers Of Chemical Elements
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and Discipline (academia), academic disciplines, discovery is the observation of new Phenomenon, phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and action (philosophy), actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

18th-century Spanish Chemists
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.

Mineralogist
Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization. History Early writing on mineralogy, especially on gemstones, comes from ancient Babylonia, the ancient Greco-Roman world, ancient and medieval China, and Sanskrit texts from ancient India and the ancient Islamic world. Books on the subject included the ''Naturalis Historia'' of Pliny the Elder, which not only described many different minerals but also explained many of their properties, and Kitab al Jawahir (Book of Precious Stones) by Persian scientist Al-Biruni. The German Renaissance specialist Georgius Agricola wrote works such as '' De re metallica'' (''On Metals'', 1556) and ''De Natura Fossilium'' (''O ...

Bogotá
Bogotá (, also , , ), officially Bogotá, Distrito Capital, abbreviated Bogotá, D.C., and formerly known as Santa Fe de Bogotá (; ) during the Spanish period and between 1991 and 2000, is the capital city of Colombia, and one of the largest cities in the world. The city is administered as the Capital District, as well as the capital of, though not part of, the surrounding department of Cundinamarca. Bogotá is a territorial entity of the first order, with the same administrative status as the departments of Colombia. It is the political, economic, administrative, and industrial center of the country. Bogotá was founded as the capital of the New Kingdom of Granada on 6 August 1538 by Spanish conquistador Gonzalo Jiménez de Quesada after a harsh expedition into the Andes conquering the Muisca, the indigenous inhabitants of the Altiplano. Santafé (its name after 1540) became the seat of the government of the Spanish Royal Audiencia of the New Kingdom of Granada (cre ...

Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of subdisciplines of chemistry. Materials scientists and metallurgists share much of the same education and skills with chemists. The work of chemists is often related to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tungsten
Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements barring carbon (which sublimes at normal pressure), melting at . It also has the highest boiling point, at . Its density is , comparable with that of uranium and gold, and much higher (about 1.7 times) than that of lead. Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work. However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten occurs in many ...
