Reginald Aldworth Daly
Reginald Aldworth Daly (March 18, 1871 – September 19, 1957) was a Canadian geologist. Biography Reginald Daly was educated at the University of Toronto, where geologist A.P. Coleman persuaded him away from teaching mathematics and into Earth Sciences. He attained his PhD at Harvard, and did postgraduate work in Germany and France. After working as a field geologist for the International Boundary Commission, he was a professor, and headed the Department of Geology at Harvard University from 1912 until 1942. Daly was president of The Geological Society of America in 1932. For the Boundary Commission, working in six field seasons, Daly mapped the border from the Pacific Ocean to the Great Plains, a rugged swath long and wide – an area of about . He documented the geology alone, but had the help of one field assistant and numerous wranglers and porters. He collected 1,500 rock specimens and made 960 thin sections, using a German polishing technique he learnt as a student. The p ...

Napanee
Greater Napanee is a town in Eastern Ontario, southeastern Ontario, Canada, approximately west of Kingston, Ontario, Kingston and the county seat of Lennox and Addington County. It is located on the eastern end of the Bay of Quinte. Greater Napanee municipality was created by amalgamating the old Town of Napanee with the townships of Adolphustown, North and South Fredericksburgh, and Richmond in 1999. Greater Napanee is co-extensive with the original Lennox County, Ontario, Lennox County. The town is home to the Allan Macpherson House, a historic 1826 property that is now a museum. Macpherson was a major in the Lennox militia, operated the town's grist and saw mills, as well as the distillery and general store. He served as post master and land agent, operated the first local printing press and helped fund the establishment of many local schools and churches. The home sits on the banks of the Napanee River, which runs through the town. The largest employer is a Goodyear Tire an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Society Of America
The Geological Society of America (GSA) is a nonprofit organization dedicated to the advancement of the geosciences. History The society was founded in Ithaca, New York, in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hitchcock, John R. Procter and Edward Orton and has been headquartered at 3300 Penrose Place, Boulder, Colorado, US, since 1967. GSA began with 100 members under its first president, James Hall. In 1889 Mary Emilie Holmes became its first female member. It grew slowly but steadily to 600 members until 1931, when a nearly $4 million endowment from 1930 president R. A. F. Penrose Jr. jumpstarted GSA's growth. As of December 2017, GSA had more than 25,000 members in over 100 countries. The society has six regional sections in North America, three interdisciplinary interest groups, and eighteen specialty divisions. Activities The stated mission of GSA is "to advance geoscience research and discovery, service to society, stewardship of Earth, an ...

Alexander Cheves Haskell
Alexander Cheves Haskell (September 22, 1839 – April 13, 1910) was a Colonel in the Confederate Army during the American Civil War and a Democratic politician in postbellum South Carolina. Early life Haskell was born in Abbeville County and raised in Columbia, where he graduated second in his class from South Carolina College and was a member of the Delta Kappa Epsilon fraternity, right before the start of the American Civil War. Civil War He enthusiastically volunteered for service in the Confederate Army and was mustered in the First Regiment of the South Carolina Volunteer Infantry, serving as an Assistant Adjutant General for Maxcy Gregg. En route to Virginia in September 1861 for action in the Eastern Theater, Haskell married Rebecca Coles Singleton in Charlottesville. She died on June 26, 1862, after the birth of a daughter six days earlier. The First South Carolina Regiment initially saw significant action in 1862 at the Seven Days Battles and would play a ...

Giant Impact Hypothesis
The giant-impact hypothesis, sometimes called the Big Splash, or the Theia Impact, suggests that the Moon formed from the ejecta of a collision between the proto-Earth and a Mars-sized planet, approximately 4.5 billion years ago, in the Hadean eon (about 20 to 100 million years after the Solar System coalesced). The colliding body is sometimes called Theia, from the name of the mythical Greek Titan who was the mother of Selene, the goddess of the Moon. Analysis of lunar rocks, published in a 2016 report, suggests that the impact might have been a direct hit, causing a thorough mixing of both parent bodies. The giant-impact hypothesis is currently the favored scientific hypothesis for the formation of the Moon. Supporting evidence includes: * Earth's spin and the Moon's orbit have similar orientations. * The Earth–Moon system contains an anomalously high angular momentum. Meaning, the momentum contained in Earth's rotation, the Moon's rotation, and the Moon revolving aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesosphere (mantle)
The lower mantle, historically also known as the mesosphere, represents approximately 56% of Earth's total volume, and is the region from 660 to 2900 km below Earth#Surface, Earth's surface; between the transition zone (Earth), transition zone and the Earth's outer core, outer core. The preliminary reference Earth model (PREM) separates the lower mantle into three sections, the uppermost (660–770 km), mid-lower mantle (770–2700 km), and the D layer (2700–2900 km). Pressure and temperature in the lower mantle range from 24–127 GPa and 1900–2600 Kelvin, K. It has been proposed that the composition of the lower mantle is pyrolite, pyrolitic, containing three major phases of silicate perovskite, bridgmanite, ferropericlase, and calcium-silicate perovskite. The high pressure in the lower mantle has been shown to induce a spin transition of iron-bearing bridgmanite and ferropericlase, which may affect both mantle plume dynamics and lower mantle chemistry. ...

Plate Tectonics
Plate tectonics (from the la, label=Late Latin, tectonicus, from the grc, τεκτονικός, lit=pertaining to building) is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago. The model builds on the concept of ''continental drift'', an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s. Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates (depending on how they are defined) and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: '' convergent'', '' divergent'', or ''transform''. Earthquakes, volcanic activity, mountain-building, and oceanic tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
And Yet It Moves
''And Yet It Moves'' is a puzzle-platform game developed by Independent video game development, independent developer Broken Rules. The game was released for Microsoft Windows, Mac OS X, and Linux on April 2, 2009, and for Wii as a WiiWare title in August 2010. ''And Yet It Moves'' was originally designed as a computer science project at the Vienna University of Technology in 2007. When the original prototype won or was nominated for awards at various independent game festivals, the team decided to create a full version of the game. ''And Yet It Moves'' focuses on moving the player character through a series of hazardous environments. The player possesses the ability to freely rotate the entire game world, transforming walls into floors and vice versa.

Galileo Galilei
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath. Commonly referred to as Galileo, his name was pronounced (, ). He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the "father" of observational astronomy, modern physics, the scientific method, and modern science. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances". He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects. His contributions to observational astronomy include telescopic confirmation of the phases of Venus, observation of the four largest satellites of Jupiter, observation of Saturn's rings, and a ...

Continental Drift
Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. A pioneer of the modern view of mobilism was the Austrian geologist Otto Ampferer.Helmut W. Flügel: Die virtuelle Welt des Otto Ampferer und die Realität seiner Zeit'. In: Geo. Alp., Vol. 1, 2004. The concept was independently and more fully developed by Alfred Wegener in 1912, but the hypothesis was rejected by many for lack of any motive mechanism. The English geologist Arthur Holmes later proposed mantle convection for that mechanism. History Early history Abraham Ortelius , Theodor Christoph Lilienthal (1756), A ...

Alfred Wegener
Alfred Lothar Wegener (; ; 1 November 1880 – November 1930) was a German climatologist, geologist, geophysicist, meteorologist, and polar researcher. During his lifetime he was primarily known for his achievements in meteorology and as a pioneer of polar research, but today he is most remembered as the originator of continental drift hypothesis by suggesting in 1912 that the continents are slowly drifting around the Earth (German: '). His hypothesis was controversial and widely rejected by mainstream geology until the 1950s, when numerous discoveries such as palaeomagnetism provided strong support for continental drift, and thereby a substantial basis for today's model of plate tectonics. Wegener was involved in several expeditions to Greenland to study polar air circulation before the existence of the jet stream was accepted. Expedition participants made many meteorological observations and were the first to overwinter on the inland Greenland ice sheet and the first to ...

Arthur Holmes
Arthur Holmes (14 January 1890 – 20 September 1965) was an English geologist who made two major contributions to the understanding of geology. He pioneered the use of radiometric dating of minerals, and was the first earth scientist to grasp the mechanical and thermal implications of mantle convection, which led eventually to the acceptance of plate tectonics. Life He was born in Hebburn, County Durham, near Newcastle upon Tyne, the son of David Holmes, a cabinet-maker, and his wife, Emily Dickinson. As a child, he lived in Low Fell, Gateshead, and attended the Gateshead Higher Grade School (later Gateshead Grammar School). At 17, he enrolled to study physics at the Royal College of Science (now Imperial College London), but took a course in geology in his second year, which settled his future, against the advice of his tutors. Surviving on a scholarship of £60/year was difficult and on graduating hall, he took a job prospecting for minerals in Mozambique. After six months, ...
