Clarence Augustus Chant (May 31, 1865 – November 18, 1956) was a Canadian astronomer and physicist. Early life and education Chant was born in Hagerman's Corners, Ontario to Christopher Chant and Elizabeth Croft. In 1882 he attended Markham High School, where he demonstrated a mathematical ability. After graduation, he attended St. Catherines Collegiate Institute and York County Model School in Toronto. He left to work as an instructor in 1884, and taught at Maxwell, Osprey Township for the following three years. By 1887 he began studying mathematics and physics at the University College of the University of Toronto, graduating in 1890. Career Upon graduation, Chant became a civil servant in Ottawa, working as a temporary clerk in the office of the Auditor General. The job offered limited prospects; however, in 1891 he was offered a fellowship at University of Toronto, where he gained an appointment as a lecturer of physics the following year.

David Dunlap Observatory
The David Dunlap Observatory (DDO) is an astronomical observatory site in Richmond Hill, Ontario, Canada. Established in 1935, it was owned and operated by the University of Toronto until 2008. It was then acquired by the city of Richmond Hill, which provides a combination of heritage preservation, unique recreation opportunities and a celebration of the astronomical history of the site. Its primary instrument is a reflector telescope, at one time the second-largest telescope in the world, and still the largest in Canada. Several other telescopes are also located at the site, which formerly also included a small radio telescope. The scientific legacy of the David Dunlap Observatory continues in the Dunlap Institute for Astronomy & Astrophysics, a research institute at the University of Toronto established in 2008. The DDO is the site of a number of important scientific studies, including pioneering measurements of the distance to globular clusters, providing the first direct ev ...

Higher Education In Canada
Higher education in Canada includes provincial, territorial, indigenous and military higher education systems. Higher education systems in Canada In Canada, the constitutional responsibility for higher education primarily rests with the provinces of Canada per the ''Constitution Act, 1867''. The decision was contentious from its inception. As a result of this constitutional arrangement, a distinctive system of education, including higher education, has evolved in each province and territory. The federal government's direct involvement in higher education is currently limited to the Canadian Military Colleges and funding the education of aboriginal peoples. The higher education systems in Canada's ten provinces include their historical development, organization (e.g., structure, governance, and funding), and goals (e.g., participation, access, and mobility). Each of the three territories in Canada (i.e., Nunavut, Northwest Territories, and Yukon) have separate higher education ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chant (crater)
Chant is a lunar impact crater that is located on the far side of the Moon, behind the southwest limb as seen from the Earth. It lies within the southwestern part of the blanket of ejecta surrounding the Mare Orientale, beyond the Montes Cordillera mountain ring. To the west-northwest is the large walled plain Blackett. Southward is the crater Mendel. This is a nearly circular crater with a slight outward bulge in the northeast wall. The outer rim is sharp-edged, and the inner sides slope directly downward with only some minor terraces along the east wall. The interior floor is somewhat irregular, particularly in the southern half. There is a small central peak at the midpoint of the floor. The name Chant was officially adopted by the International Astronomical Union in 1970 and named for Clarence Chant. This crater lies to the northwest of the Mendel-Rydberg Basin, a 630 km wide impact basin of Nectarian The Nectarian Period of the lunar geologic timescale runs from 3 ...

David Alexander Dunlap
David Alexander Dunlap (October 13, 1863 − October 29, 1924) was a Canadian lawyer, mining company executive and philanthropist. He and his partners acquired an Ontario silver mine called LaRose, which was the basis of the great fortune he came to amass. As a philanthropist, he became interested in financing the construction of the astronomical observatory at the University of Toronto, which due to his sudden death, was completed by his widow Jessie Dunlap. In his memory, the astronomical facility promoted by astronomer Clarence Chant was named David Dunlap Observatory. Career After educating himself in public schools and high school in his hometown of Pembroke, he continued his studies in Barrie, Ontario and Toronto, where he graduated with a law degree from Osgoode Hall. He subsequently moved to Mattawa, Ontario, where he began practicing law. But he soon became involved in mining prospecting with the two Timmins brothers, also residents of Mattawa, and the trio successfully ...

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ''annu ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
