Morten Wormskjold
Morten Wormskjold (16 January 1783 – 29 November 1845) was a Danish botanist and explorer. He collected plants in Greenland and Kamchatka. Early life Morten Wormskjold was born in Copenhagen to a recently nobilitated family of civil servants in the Danish state administration. His parents were Peder Wormskiold (1750–1824), a royal councilor, and Margrethe M. de Teilman (1757–1837). He received private tuition and graduated in law in 1805. He then studied botany under professor J. W. Hornemann at the University of Copenhagen. In 1807, he accompanied Hornemann and the Norwegian botanist Christen Smith on a trip to Norway to collect plant specimens to support descriptions and form the basis of illustrations intended for the grand plate work Flora Danica, at that time edited by Hornemann. The two Danes had to leave Norway due to the Napoleonic Wars and no specimen seemed to have been preserved from the trip. Greenland In 1812–1813, Wormskjold made a botanical collec ...

Mineralogy
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' ...

Otto Von Kotzebue
Otto von Kotzebue (russian: О́тто Евста́фьевич Коцебу́, tr. ; – ) was a Russian officer and navigator in the Imperial Russian Navy. He was born in Reval. He was known for his explorations of Oceania. Early life and education Born into the Kotzebue family of Brandenburgish origin, originating in Kossebau in Altmark, he was the second son of writer and diplomat August von Kotzebue and his wife, he was born in Reval (now Tallinn, Estonia), then part of the Russian Empire. After attending the Saint Petersburg school of cadets, he accompanied Adam Johann von Krusenstern on his voyage of 1803–1806. Both attested to the prominence of Baltic Germans in Imperial Russia's naval expeditions around 1800. Naval career On promotion to lieutenant, Kotzebue was placed in command of an expedition, fitted out at the expense of the imperial chancellor, Count Nikolay Rumyantsev, in the brig ''Rurik''. In this vessel, with only twenty-seven men, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russia
Russia (, , ), or the Russian Federation, is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world, with its internationally recognised territory covering , and encompassing one-eighth of Earth's inhabitable landmass. Russia extends across eleven time zones and shares land boundaries with fourteen countries, more than any other country but China. It is the world's ninth-most populous country and Europe's most populous country, with a population of 146 million people. The country's capital and largest city is Moscow, the largest city entirely within Europe. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas include Novosibirsk, Yekaterinburg, Nizhny Novgorod, and Kazan. The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries CE. Kievan Rus' arose as a state in the 9th century, and in 988, it adopted Orthodox Christianity from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vascular Plants
Vascular plants (), also called tracheophytes () or collectively Tracheophyta (), form a large group of land plants ( accepted known species) that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida ''sensu lato''. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "higher plants", as it was believed that they were further evolved than other plants due to being more complex organisms. However, this is an antiquated remnant of the obsolete scala naturae, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugenius Warming
Eugenius (died 6 September 394) was a usurper in the Western Roman Empire (392–394) against Emperor Theodosius I. While Christian himself, Eugenius capitalized on the discontent in the West caused by Theodosius' religious policies targeting pagans. He renovated the pagan Temple of Venus and Roma and restored the Altar of Victory, after continued petitions from the Roman Senate. Eugenius replaced Theodosius' administrators with men loyal to him, including pagans. This revived the pagan cause. His army fought the army of Theodosius at the Battle of the Frigidus, where Eugenius was captured and executed. Life A Christian and former teacher of grammar and rhetoric, as well as ''magister scriniorum'', Eugenius was an acquaintance of Arbogast, the ''magister militum''. Arbogast was of Frankish origin and ''de facto'' ruler of the western portion of the Empire. Rise to power Following the death of Valentinian II, Eugenius was elevated to ''augustus'' on 22 August 392 at Lyons, by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ab ...

Molluscs
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Allan (mineralogist)
Thomas Allan of Lauriston FRS FRSE FSA FLS (17 July 1777 – 12 September 1833) was a British mineralogist. Life Allan was born in Edinburgh, Scotland, on 17 July 1777, the son of Robert Allan (1748–1818), a banker. He was educated at the High School of Edinburgh and took up banking as profession; but he is remembered today for his contributions to mineral science. At an early age Allan became fascinated with minerals and he began to accumulate a large mineral collection that was subsequently bequeathed to his son Robert Allan FRSE. This collection was later incorporated into Robert Greg's, which was ultimately acquired by the British Museum of Natural History in the mid-nineteenth century. In 1813, Allan was influential in securing a mineralogy post in the Dublin Philosophical Society for the German mineralogist Karl Ludwig Giesecke (1761–1833). Allan was elected as Fellow of the Royal Society of Edinburgh in 1805, his proposers being Sir James Hall, William Wright an ...
