Arcangelo Scacchi
Arcangelo Scacchi (9 February 1810 – 11 October 1893) was an Italian physician, mineralogist, malacology, malacologist, and naturalist. He served as a professor of mineralogy at the University of Naples Federico II, University of Naples. Between 1841 and 1884 he explored the volcanic lava flows of Mount Somma and named several minerals claimed as new forms from the deposits although they were subsequently re-identified as being already described. He also contributed to the study of volcanoes and molluscs. Scacchi was born in Gravina in Puglia, Gravina, Puglia to lawyer Patrizio and Giovanna Pentibove. He was educated at the Bari seminary before joining the University of Naples Federico II, University of Naples in 1827, graduating with a degree in medicine in 1831. He practiced medicine in Naples where he met Leopoldo Pilla and took an interest in mineralogy and geology, and following the death of Matteo Tondi, Pilla appointed Scacchi as an assistant in 1835. He described several n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phlegraean Fields
The Phlegraean Fields ( it, Campi Flegrei ; nap, Campe Flegree, from Ancient Greek 'to burn') is a large region of supervolcanic calderas situated to the west of Naples, Italy. It was declared a regional park in 2003. The area of the caldera consists of 24 craters and volcanic edifices; most of them lie under water. Hydrothermal activity can be observed at Lucrino, Agnano and the town of Pozzuoli. There are also effusive gaseous manifestations in the Solfatara crater, the mythological home of the Roman god of fire, Vulcan. This area is monitored by the Vesuvius Observatory. It is considered a supervolcano. The area also features bradyseismic phenomena, which are most evident at the Macellum of Pozzuoli (misidentified as a temple of Serapis): bands of boreholes left by marine molluscs on marble columns show that the level of the site in relation to sea level has varied.

1810 Births
Year 181 ( CLXXXI) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Burrus (or, less frequently, year 934 ''Ab urbe condita''). The denomination 181 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Chirality (chemistry)
In chemistry, a molecule or ion is called chiral () if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (). The terms are derived from Ancient Greek χείρ (''cheir'') 'hand'; which is the canonical example of an object with this property. A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers; they are often distinguished as either "right-handed" or "left-handed" by their absolute configuration or some other criterion. The two enantiomers have the same chemical properties, except when reacting with other chiral compounds. They also have the same physical properties, except that they often have opposite optical activities. A homogeneous mixture of the two enantiomers in equal parts is said to be racemic, and it usually differs chemically and physically from the pure enantiomers. Chiral molecules ...

Savoy
Savoy (; frp, Savouè ; french: Savoie ) is a cultural-historical region in the Western Alps. Situated on the cultural boundary between Occitania and Piedmont, the area extends from Lake Geneva in the north to the Dauphiné in the south. Savoy emerged as the feudal County of Savoy ruled by the House of Savoy during the 11th to 14th centuries. The original territory, also known as "ducal Savoy" or "Savoy proper", is largely co-terminous with the modern French Savoie and Haute-Savoie ''départements'', but the historical expansion of Savoyard territories, as the Duchy of Savoy (1416–1860) included parts of what is now western Italy and southwestern Switzerland. The current border between France and Italy is due to the Plombières Agreement of 1858, which in preparation for the unification of Italy ceded western Savoy to France, while the eastern territories in Piedmont and Liguria were retained by the House of Savoy, which was to become the ruling dynasty of Italy. ...

Giuseppe Garibaldi
Giuseppe Maria Garibaldi ( , ;In his native Ligurian language, he is known as ''Gioxeppe Gaibado''. In his particular Niçard dialect of Ligurian, he was known as ''Jousé'' or ''Josep''. 4 July 1807 – 2 June 1882) was an Italian general, patriot, revolutionary and republican. He contributed to Italian unification and the creation of the Kingdom of Italy. He is considered one of the greatest generals of modern times and one of Italy's " fathers of the fatherland", along with Camillo Benso, Count of Cavour, Victor Emmanuel II of Italy and Giuseppe Mazzini. Garibaldi is also known as the "''Hero of the Two Worlds''" because of his military enterprises in South America and Europe. Garibaldi was a follower of the Italian nationalist Mazzini and embraced the republican nationalism of the Young Italy movement. He became a supporter of Italian unification under a democratic republican government. However, breaking with Mazzini, he pragmatically allied himself with the monarch ...

House Of Bourbon
The House of Bourbon (, also ; ) is a European dynasty of French origin, a branch of the Capetian dynasty, the royal House of France. Bourbon kings first ruled France and Navarre in the 16th century. By the 18th century, members of the Spanish Bourbon dynasty held thrones in Spain, Naples, Sicily, and Parma. Spain and Luxembourg have monarchs of the House of Bourbon. The royal Bourbons originated in 1272, when the youngest son of King Louis IX married the heiress of the lordship of Bourbon. Anselme, Père. ‘'Histoire de la Maison Royale de France'’, tome 4. Editions du Palais-Royal, 1967, Paris. pp. 144–146, 151–153, 175, 178, 180, 185, 187–189, 191, 295–298, 318–319, 322–329. (French). The house continued for three centuries as a cadet branch, serving as nobles under the Direct Capetian and Valois kings. The senior line of the House of Bourbon became extinct in the male line in 1527 with the death of Charles III, Duke of Bourbon. This made the junior Bour ...

Luigi Palmieri
Luigi Palmieri (22 April 1807 – 9 September 1896) was an Italian physicist and meteorologist. He was famous for his scientific studies of the eruptions of Mount Vesuvius, for his researches on earthquakes and meteorological phenomena and for improving the seismograph of the time. Biography Palmieri was born in Faicchio, Benevento, Italy and died in Naples, Italy at the age of 89. Palmieri received a degree in physics from the University of Naples. In 1845, he was made Professor of Physics at the Royal Naval School in Naples and in 1847 was appointed as Chair of Physics at the university. In 1848, he began working at the Vesuvius Observatory and in 1854 was appointed as Director of the Observatory. Using an electromagnetic seismometer for the detection and measurement of ground tremors, Palmieri was able to detect very slight movements in trying to predict volcanic eruptions. Furthermore, he was the first to detect the presence of Helium on Earth on the lava of Mount Vesu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Lyell
Sir Charles Lyell, 1st Baronet, (14 November 1797 – 22 February 1875) was a Scottish geologist who demonstrated the power of known natural causes in explaining the earth's history. He is best known as the author of ''Principles of Geology'' (1830–33), which presented to a wide public audience the idea that the earth was shaped by the same natural processes still in operation today, operating at similar intensities. The philosopher William Whewell termed this gradualistic view "uniformitarianism" and contrasted it with catastrophism, which had been championed by Georges Cuvier and was better accepted in Europe. The combination of evidence and eloquence in ''Principles'' convinced a wide range of readers of the significance of "deep time" for understanding the earth and environment. Lyell's scientific contributions included a pioneering explanation of climate change, in which shifting boundaries between oceans and continents could be used to explain long-term variations ...

Christian Leopold Von Buch
Christian Leopold von Buch (26 April 1774 – 4 March 1853), usually cited as Leopold von Buch, was a German geologist and paleontologist born in Stolpe an der Oder (now a part of Angermünde, Brandenburg) and is remembered as one of the most important contributors to geology in the first half of the nineteenth century. His scientific interest was devoted to a broad spectrum of geological topics: volcanism, petrology, fossils, stratigraphy and mountain formation. His most remembered accomplishment is the scientific definition of the Jurassic system. Biography Buch studied with Alexander von Humboldt under Abraham Gottlob Werner at the mining school in Freiberg, Saxony. He afterwards completed his education at the universities of Halle and Göttingen. German and Italian explorations He began writing on geological topics early in life. His ''Versuch einer mineralogischen Beschreibung von Landeck'' (Breslau, 1797) was translated into French (Paris, 1805), and into English ...

Afghanite
Afghanite, (Na,K)22Ca10 i24Al24O96SO4)6Cl6, is a hydrous sodium, calcium, potassium, sulfate, chloride, carbonate alumino-silicate mineral. Afghanite is a feldspathoid of the cancrinite group and typically occurs with sodalite group minerals. It forms blue to colorless, typically massive crystals in the trigonal crystal system. The lowering of the symmetry from typical (for cancrinite group) hexagonal one is due to ordering of Si and Al. It has a Mohs hardness of 5.5 to 6 and a specific gravity of 2.55 to 2.65. It has refractive index values of nω=1.523 and nε=1.529. It has one direction of perfect cleavage and exhibits conchoidal fracture. It fluoresces a bright orange. It was discovered in 1968 in the Lapis-lazuli Mine, Sar-e-Sang, Badakhshan Province, Afghanistan and takes its name from that country. It has also been described from localities in Germany, Italy, the Pamir Mountains of Tajikistan, near Lake Baikal in Siberia, New York and Newfoundland. It occurs as veinl ...
