Al-Biruni
Abu Rayhan Muhammad ibn Ahmad al-Biruni (973 – after 1050) commonly known as al-Biruni, was a Khwarazmian Iranian in scholar and polymath during the Islamic Golden Age. He has been called variously the "founder of Indology", "Father of Comparative Religion", "Father of modern geodesy", and the first anthropologist. Al-Biruni was well versed in physics, mathematics, astronomy, and natural sciences, and also distinguished himself as a historian, chronologist, and linguist. He studied almost all the sciences of his day and was rewarded abundantly for his tireless research in many fields of knowledge. Royalty and other powerful elements in society funded Al-Biruni's research and sought him out with specific projects in mind. Influential in his own right, Al-Biruni was himself influenced by the scholars of other nations, such as the Greeks, from whom he took inspiration when he turned to the study of philosophy. A gifted linguist, he was conversant in Khwarezmian, Persian, Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Michell
John Michell (; 25 December 1724 – 21 April 1793) was an English people, English natural philosophy, natural philosopher and clergyman who provided pioneering insights into a wide range of scientific fields including astronomy, geology, optics, and gravitation. Considered "one of the greatest unsung scientists of all time", he is the first person known to have proposed the existence of black holes, and the first to have suggested that earthquakes travelled in seismic waves, (seismic) waves. Recognizing that double stars were a product of mutual gravitation, he was the first to apply statistics to the Cosmology, study of the cosmos. He invented an apparatus to measure the Earth mass, mass of the Earth, and explained how to manufacture an artificial magnet. He has been called the father both of seismology and of magnetometry. According to one science journalist, "a few specifics of Michell's work really do sound like they are ripped from the pages of a twentieth century astrono ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classification, ... [...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 variati ...

Biostratigraphy
Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock Stratum, strata by using the fossil assemblages contained within them.Hine, Robert. “Biostratigraphy.” ''Oxford Reference: Dictionary of Biology'', 8th ed., Oxford University Press, 2019. The primary objective of biostratigraphy is ''correlation'', demonstrating that a particular Horizon (geology), horizon in one geological section represents the same period of time as another horizon at a different section. Fossils within these strata are useful because sediments of the same age can look completely different, due to local variations in the Sedimentary depositional environment, sedimentary environment. For example, one section might have been made up of clays and marls, while another has more chalky limestones. However, if the fossil species recorded are similar, the two sediments are likely to have been laid down around the same time. Ideally these fossils are used to ...

Catastrophism
In geology, catastrophism theorises that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope. This contrasts with uniformitarianism (sometimes called gradualism), according to which slow incremental changes, such as erosion, brought about all the Earth's geological features. The proponents of uniformitarianism held that the present was "the key to the past", and that all geological processes (such as erosion) throughout the past resembled those that can be observed today. Since the 19th-century disputes between catastrophists and uniformitarians, a more inclusive and integrated view of geologic events has developed, in which the scientific consensus accepts that some catastrophic events occurred in the geologic past, but regards these as explicable as extreme examples of natural processes which can occur. Proponents of catastrophism proposed that each geological epoch ended with violent and sudden natural catastrophes such as m ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...

William Maclure
William Maclure (27 October 176323 March 1840) was an Americanized Scottish geologist, cartographer and philanthropist. He is known as the 'father of American geology'. As a social experimenter on new types of community life, he collaborated with British social reformer Robert Owen, (1771–1854), in Indiana, United States. Maclure had a highly successful mercantile career, making a fortune that allowed him to retire in 1797 at the early age of 34 to pursue his scientific, geological and other interests. In 1809 he made the earliest attempt at a geological map of the United States of America. Biography Early life, business, and education Maclure was born in 1763 in Ayr, Scotland. After a brief visit to New York City in 1782, he began work with the merchants Miller, Hart & Co, who traded and shipped goods to and from America. Maclure was based in the London office but regularly travelled to France and Ireland on business. In 1796 business affairs took him to Virginia, which h ...

Bath, Somerset
Bath () is a city in the Bath and North East Somerset unitary area in the county of Somerset, England, known for and named after its Roman-built baths. At the 2021 Census, the population was 101,557. Bath is in the valley of the River Avon, west of London and southeast of Bristol. The city became a World Heritage Site in 1987, and was later added to the transnational World Heritage Site known as the "Great Spa Towns of Europe" in 2021. Bath is also the largest city and settlement in Somerset. The city became a spa with the Latin name ' ("the waters of Sulis") 60 AD when the Romans built baths and a temple in the valley of the River Avon, although hot springs were known even before then. Bath Abbey was founded in the 7th century and became a religious centre; the building was rebuilt in the 12th and 16th centuries. In the 17th century, claims were made for the curative properties of water from the springs, and Bath became popular as a spa town in the Georgian era. ...

William Smith (geologist)
William 'Strata' Smith (23 March 1769 – 28 August 1839) was an English geologist, credited with creating the first detailed, nationwide geological map of any country. At the time his map was first published he was overlooked by the scientific community; his relatively humble education and family connections prevented him from mixing easily in learned society. Financially ruined, Smith spent time in debtors' prison. It was only late in his life that Smith received recognition for his accomplishments, and became known as the "Father of English Geology". Early life Smith was born in the village of Churchill, Oxfordshire, the son of John Smith (1735–1777), the village blacksmith, and his wife Ann (''née'' Smith; 1745–1807). His father died when he was eight years old, and he and his siblings were raised by his uncle, a farmer also named William Smith. Largely self-educated, Smith was intelligent and observant, read widely from an early age, and with an aptitude for mathem ...

James Hutton
James Hutton (; 3 June O.S.172614 June 1726 New Style. – 26 March 1797) was a Scottish geologist, agriculturalist, chemical manufacturer, naturalist and physician. Often referred to as the father of modern geology, he played a key role in establishing geology as a modern science. Hutton advanced the idea that the physical world's remote history can be inferred from evidence in present-day rocks. Through his study of features in the landscape and coastlines of his native Scottish lowlands, such as Salisbury Crags or Siccar Point, he developed the theory that geological features could not be static but underwent continuing transformation over indefinitely long periods of time. From this he argued, in agreement with many other early geologists, that the Earth could not be young. He was one of the earliest proponents of what in the 1830s became known as uniformitarianism, the science which explains features of the Earth's crust as the outcome of continuing natural processes ...
