Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational and theoretical. Observational astronomers make direct observations of celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate models of things that cannot be observed. Because it takes millions to billions of years for a system of stars or a galaxy to complete a life cycle, astronomers must observe sna ...

Blue Straggler
A blue straggler is a main-sequence star in an open or globular cluster that is more luminous and bluer than stars at the main sequence turnoff point for the cluster. Blue stragglers were first discovered by Allan Sandage in 1953 while performing photometry of the stars in the globular cluster M3. Standard theories of stellar evolution hold that the position of a star on the Hertzsprung–Russell diagram should be determined almost entirely by the initial mass of the star and its age. In a cluster, stars all formed at approximately the same time, and thus in an H–R diagram for a cluster, all stars should lie along a clearly defined curve set by the age of the cluster, with the positions of individual stars on that curve determined solely by their initial mass. With masses two to three times that of the rest of the main-sequence cluster stars, blue stragglers seem to be exceptions to this rule. The resolution of this problem is likely related to interactions between two or m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsch (crater)
Deutsch is a lunar impact crater on the far side of the Moon. It lies to the southwest of the larger crater Seyfert. About one crater to the east-northeast is Polzunov. Its name comes from Armin Joseph Deutsch, an American astronomer and science-fiction author. This crater has a relatively low, eroded rim that is heavily damaged along the southeastern section. This portion is overlain by Deutsch F along the east and Deutsch L to the south, with an irregular region between these two formations. The interior floor of Deutsch is relatively level, but is marked by a number of small impacts. A ray from Giordano Bruno Giordano Bruno (; ; la, Iordanus Brunus Nolanus; born Filippo Bruno, January or February 1548 – 17 February 1600) was an Italian philosopher, mathematician, poet, cosmological theorist, and Hermetic occultist.

Thornton Leigh Page
Thornton Leigh Page was an American professor of astronomy at the University of Chicago and at Wesleyan University. He became embroiled in the controversy over unidentified flying objects (UFOs) after serving briefly on the Robertson Panel, a Central Intelligence Agency–sponsored committee of scientists assembled in Washington, D.C. from 14–18 January 1953 to study the available evidence on UFOs. Early life Thornton Page was born in New Haven, CT on 13 August 1913 to Leigh Page, a physics instructor at Yale University, and Mary Page, trained as a nurse. He went on to receive a B.S. in physics from Yale in 1934, and was named a Rhodes Scholar, later earning a D.Phil. from Oxford University in 1938. Military career During World War II, he served in the Pacific Theater with the minelaying operations research group, serving in Guan, Tinian, and at sea. He was in Tokyo for the Japanese surrender, and had reported on the atomic tests at Bikini. Professional career After hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets polic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Retro Hugo
The Hugo Award is an annual literary award for the best science fiction or fantasy works and achievements of the previous year, given at the World Science Fiction Convention and chosen by its members. The Hugo is widely considered the premier award in science fiction. The award is administered by the World Science Fiction Society. It is named after Hugo Gernsback, the founder of the pioneering science fiction magazine ''Amazing Stories''. Hugos were first given in 1953, at the 11th World Science Fiction Convention, and have been awarded every year since 1955. The awards were originally given in seven categories. These categories have changed over the years, and the award is currently conferred in seventeen categories of written and dramatic works. The winners receive a trophy consisting of a stylized rocket ship on a base; the design of the trophy changes each year, though the rocket itself has been standardized since 1984. The Hugo Awards are considered "the premier award in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topology
In mathematics, topology (from the Greek words , and ) is concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling, and bending; that is, without closing holes, opening holes, tearing, gluing, or passing through itself. A topological space is a set endowed with a structure, called a '' topology'', which allows defining continuous deformation of subspaces, and, more generally, all kinds of continuity. Euclidean spaces, and, more generally, metric spaces are examples of a topological space, as any distance or metric defines a topology. The deformations that are considered in topology are homeomorphisms and homotopies. A property that is invariant under such deformations is a topological property. Basic examples of topological properties are: the dimension, which allows distinguishing between a line and a surface; compactness, which allows distinguishing between a line and a circle; ...

A Subway Named Mobius
"A Subway Named Mobius" is a 1950 science fiction short story by American astronomer Armin Joseph Deutsch. It imagines the results of increasing the complexity of the Boston MTA system (now the MBTA) with a new interconnection. It has been collected in anthologies since its original publication, and was nominated for a Retro Hugo Award in 2001, placing fourth in the final vote. Plot Shortly after the opening of a new track known as the Boylston Shuttle, Boston MTA train No. 86 goes missing. Whyte, the manager of the system, cannot explain its disappearance nor account for the fact that the system acts as though it was still there, drawing power and causing signals to operate automatically, sometimes miles apart. It falls to mathematician Professor Roger Tupelo of Harvard to attempt an explanation. Though not a topologist himself, he believes that the new shuttle connection caused the topological complexity of the system to increase to the point where the connectivity became i ...
