Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Quinine
Quinine is a medication used to treat malaria and babesiosis. This includes the treatment of malaria due to ''Plasmodium falciparum'' that is resistant to chloroquine when artesunate is not available. While sometimes used for nocturnal leg cramps, quinine is not recommended for this purpose due to the risk of serious side effects. It can be taken by mouth or intravenously. Malaria resistance to quinine occurs in certain areas of the world. Quinine is also used as an ingredient in tonic water to impart a bitter taste. Common side effects include headache, ringing in the ears, vision issues, and sweating. More severe side effects include deafness, low blood platelets, and an irregular heartbeat. Use can make one more prone to sunburn. While it is unclear if use during pregnancy causes harm to the baby, treating malaria during pregnancy with quinine when appropriate is still recommended. Quinine is an alkaloid, a naturally occurring chemical compound. How it works as a medicin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado
Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States census. The region has been inhabited by Native Americans and their ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", the color of the Fountain Formation outcroppings found up and down the Front Range of the Rocky Mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pikes Peak
Pikes Peak is the List of mountain ranges of Colorado#Mountain ranges, highest summit of the southern Front Range of the Rocky Mountains, in North America. The Ultra-prominent peak, ultra-prominent fourteener is located in Pike National Forest, west of downtown Colorado Springs, Colorado. The town of Manitou Springs, Colorado, Manitou Springs lies at its base. The mountain is named in honor of American explorer Zebulon Pike (though he was unable to reach the summit). The summit is higher than any point in the United States east of its longitude. Name The band of Ute people who called the Pikes Peak region their home were the Tabeguache, whose name means the "People of Sun Mountain". or "sun", is the Ute language, Ute word that was given by these first people to the mountain that we now call Pikes Peak. It is thought that the Ute people first arrived in Colorado about 500 A.D., however their oral history states that they were created on Tava. In the 1800s, when the Arapa ...

Edwin James (scientist)
Edwin P. James (August 27, 1797 – October 28, 1861), a 19th-century American botanist, geologist, linguist, and medical practitioner, was an important figure in the early exploration of the American West. James was also known for his time spent creating relationships with Native Americans in the United States, and also aiding African Americans to escape slavery. James is primarily remembered for his participation in the Stephen H. Long's Expedition of 1820, expedition of 1819-1820 led by Major Stephen Harriman Long, into still largely unknown territory acquired in the Louisiana Purchase. James served during the expedition's more productive second year. That expedition "was the first scientific survey of the region and dramatically increased the country’s geographical knowledge of the West." James was primarily responsible for producing the report, ''Account of an Expedition from Pittsburgh to the Rocky Mountains, Performed in the Years 1819, 1820'', published in 1823. During ...

Edward Bransfield
Edward Bransfield (c. 1785 – 31 October 1852) was an Irish sailor who became an officer in the British Royal Navy, serving as a master on several ships, after being impressed into service in Ireland at the age of 18. He is noted for his participation in several explorations of parts of Antarctica, including a sighting of the Trinity Peninsula in January 1820. Early life Edward Bransfield was born in Ballinacurra, County Cork, Ireland, in about 1785. While little is known of Edward's family or early life, the Bransfields are thought to have been a well-known and respected Catholic family. They may have had enough money to pay for Edward's education, but because of the Penal Laws, it is more likely that he attended a local hedge school. On 2 June 1803, Bransfield, then eighteen years old, was removed by British sailors from his father's fishing boat and impressed into the Royal Navy. He began as an ordinary seaman on the 110-gun first-rate ship of the line , where he share ... [...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, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irish People
The Irish ( ga, Muintir na hÉireann or ''Na hÉireannaigh'') are an ethnic group and nation native to the island of Ireland, who share a common history and culture. There have been humans in Ireland for about 33,000 years, and it has been continually inhabited for more than 10,000 years (see Prehistoric Ireland). For most of Ireland's recorded history, the Irish have been primarily a Gaelic people (see Gaelic Ireland). From the 9th century, small numbers of Vikings settled in Ireland, becoming the Norse-Gaels. Anglo-Normans also conquered parts of Ireland in the 12th century, while England's 16th/17th century conquest and colonisation of Ireland brought many English and Lowland Scots to parts of the island, especially the north. Today, Ireland is made up of the Republic of Ireland (officially called Ireland) and Northern Ireland (a part of the United Kingdom). The people of Northern Ireland hold various national identities including British, Irish, Northern Irish or som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabian Gottlieb Von Bellingshausen
Fabian Gottlieb Thaddeus von Bellingshausen (russian: Фадде́й Фадде́евич Беллинсга́узен, translit=Faddéy Faddéevich Bellinsgáuzen; – ) was a Russian naval officer, cartographer and explorer, who ultimately rose to the rank of admiral. He participated in the first Russian circumnavigation of the globe, and subsequently became a leader of another circumnavigation expedition that discovered the continent of Antarctica. Like Otto von Kotzebue and Adam Johann von Krusenstern, Bellingshausen belonged to the cohort of prominent Baltic German navigators who helped Russia launch its naval expeditions. Bellingshausen was born on Osel Island. He started his service in the Russian Baltic Fleet, and after distinguishing himself joined the first Russian circumnavigation of the Earth in 1803–1806, serving on the merchant ship ''Nadezhda'' under the captaincy of Adam Johann von Krusenstern. After the journey, he published a collection of maps of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Russian Navy
The Imperial Russian Navy () operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until dissolved in the wake of the February Revolution of 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Second Azov campaign in 1696. It expanded in the second half of the 18th century and reached its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size. The Imperial Navy drew its officers from the aristocracy of the Empire, who belonged to the state Russian Orthodox Church. Young aristocrats began to be trained for leadership at a national naval school. From 1818 on, only officers of the Imperial Russian Navy were appointed to the position of Chief Manager of the Russian-American Company, based in Russian America (present-day Alaska) for colonization and fur-trade developme ...

Antarctic Ice Sheet
The Antarctic ice sheet is one of the two polar ice caps of Earth. It covers about 98% of the Antarctic continent and is the largest single mass of ice on Earth, with an average thickness of over 2 kilometers. It covers an area of almost and contains of ice. A cubic kilometer of ice weighs approximately 0.92 metric gigatonnes, meaning that the ice sheet weighs ~24,380,000 gigatonnes. It holds approximately 61% of all fresh water on Earth, equivalent to about 58 meters of sea level rise if all the ice were above sea level. In East Antarctica, the ice sheet rests on a major land mass, while in West Antarctica the bed can extend to more than 2,500 m below sea level. Satellite measurements by NASA indicate a still increasing sheet thickness above the continent, outweighing the losses at the edge. The reasons for this are not fully understood, but suggestions include the climatic effects on ocean and atmospheric circulation of the ozone hole, and/or cooler ocean surface temperatu ...

Old Style And New Style Dates
Old Style (O.S.) and New Style (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, this is the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and 1923. In England, Wales, Ireland and Britain's American colonies, there were two calendar changes, both in 1752. The first adjusted the start of a new year from Lady Day (25 March) to 1 January (which Scotland had done from 1600), while the second discarded the Julian calendar in favour of the Gregorian calendar, removing 11 days from the September 1752 calendar to do so.Spathaky, MikOld Style and New Style Dates and the change to the Gregorian Calendar "Before 1752, parish registers, in addition to a new year heading after 24th March showing, for example '1733', had another heading at the end of the following December indicating '1733/4'.
