Robert Methven Petrie (May 15, 1906 – April 8, 1966) was a Canadian astronomer. He was born in Scotland but emigrated to Canada at the age of five. He grew up in Victoria, British Columbia and studied physics and mathematics at the University of British Columbia. He began working summer jobs at the Dominion Astrophysical Observatory and became fascinated with astronomy. He obtained his PhD at the University of Michigan in 1932. He taught there until 1935, when he joined the staff of the Dominion Astrophysical Observatory. In 1951 he became its director. He extensively studied spectroscopic binaries. The crater Petrie on the Moon is named after him.

Petrie (crater)
Petrie is a relatively small lunar impact crater that is located to the east of the much larger walled plain Fabry. To the east is the smaller crater Rayet. Most of the rim of Petrie is sharp-edged, with a deposit of scree Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically ha ... along the base of the inner wall. There is an outward bulge to the rim along the southwest, where the surface has slumped into the interior. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Petrie.

Canadian Expatriate Academics In The United States
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Victoria, British Columbia
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Canadian Astronomical Society
The Canadian Astronomical Society (CASCA; french: link=yes, La Société Canadienne d'Astronomie) is a Canadian society of professional astronomers, founded in 1971 and incorporated in 1983. The society is devoted to the promotion and advancement of knowledge of the universe through research and education, and its membership is open to people with a professional involvement in astronomy and related sciences. The main activities of the Society are its annual scientific meetings, the planning and realization of scientific projects, the support of the scientific activities of its members, and the dissemination of related information among members and other interested people. History Before World War II, there were few professional astronomers in Canada. There were two government-run, national observatories, the Dominion Observatory, which opened in 1905 in Ottawa, Ontario and the Dominion Astrophysical Observatory, which opened in 1918 in Saanich, British Columbia.

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] |
