Richard Conn Henry
Richard Conn Henry (born 7 March 1940) is an Academy Professor of Physics and Astronomy at Johns Hopkins University, author of one book and over 200 publications on the topics of astrophysics and various forms of astronomy including optical, radio, ultraviolet, and X-ray. He reports being part of a team that discovered "vastly more baryons than had ever before been found in the universe". He is also cited in the effort to recategorize Pluto as a dwarf planet. He initially joined the Johns Hopkins University Physics Department in 1968 as the first JHU astronomer since 1908. After a stint at NASA, he returned to help attract in 1981 the Space Telescope Science Institute to JHU, an organization that now employs 500, including 100 PhDs. More recently he has attracted popular press for the SETI ecliptic search idea and the Hanke-Henry Permanent Calendar. The SETI ecliptic search idea suggests focusing SETI efforts in the ecliptic plane in which distant hypothetical observers can see th ...

Johns Hopkins University
Johns Hopkins University (Johns Hopkins, Hopkins, or JHU) is a private university, private research university in Baltimore, Maryland. Founded in 1876, Johns Hopkins is the oldest research university in the United States and in the western hemisphere. It consistently ranks among the most prestigious universities in the United States and the world. The university was named for its first benefactor, the American entrepreneur and Quaker philanthropist Johns Hopkins. Hopkins' $7 million bequest to establish the university was the largest Philanthropy, philanthropic gift in U.S. history up to that time. Daniel Coit Gilman, who was inaugurated as :Presidents of Johns Hopkins University, Johns Hopkins's first president on February 22, 1876, led the university to revolutionize higher education in the U.S. by integrating teaching and research. In 1900, Johns Hopkins became a founding member of the American Association of Universities. The university has led all Higher education in the U ...

Baryon
In particle physics, a baryon is a type of composite subatomic particle which contains an odd number of valence quarks (at least 3). Baryons belong to the hadron family of particles; hadrons are composed of quarks. Baryons are also classified as fermions because they have half-integer spin. The name "baryon", introduced by Abraham Pais, comes from the Greek word for "heavy" (βαρύς, ''barýs''), because, at the time of their naming, most known elementary particles had lower masses than the baryons. Each baryon has a corresponding antiparticle (antibaryon) where their corresponding antiquarks replace quarks. For example, a proton is made of two up quarks and one down quark; and its corresponding antiparticle, the antiproton, is made of two up antiquarks and one down antiquark. Because they are composed of quarks, baryons participate in the strong interaction, which is mediated by particles known as gluons. The most familiar baryons are protons and neutrons, both of which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Telescope Science Institute
The Space Telescope Science Institute (STScI) is the science operations center for the Hubble Space Telescope (HST), science operations and mission operations center for the James Webb Space Telescope (JWST), and science operations center for the Nancy Grace Roman Space Telescope. STScI was established in 1981 as a community-based science center that is operated for NASA by the Association of Universities for Research in Astronomy (AURA). STScI's offices are located on the Johns Hopkins University Homewood Campus and in the Rotunda building in Baltimore, Maryland. In addition to performing continuing science operations of HST and preparing for scientific exploration with JWST and Roman, STScI manages and operates the Mikulski Archive for Space Telescopes (MAST), which holds data from numerous active and legacy missions, including HST, JWST, Kepler, TESS, Gaia, and Pan-STARRS. Most of the funding for STScI activities comes from contracts with NASA's Goddard Space Flight Center b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Streit Council
The Streit Council for a Union of Democracies is Washington, DC-based 501(c)(3) nonprofit foreign policy think tank working to unite democracies as a path toward greater individual freedom, international solidarity, and global stability. It aims for the creation of an international order of, by and for the people. History As Federal Union, Inc. The Streit Council is a successor to Federal Union Inc., founded in 1939 by Clarence Streit – a ''New York Times'' journalist and author of '' Union Now''. He proposed a union of democracies around the Atlantic that would be capable enough to deter, and if necessary defend, against any combination of totalitarian regimes - thus avoiding the outbreak of WWII. Streit also advocated this initial federation of the world's leading democracies – with a common constitution, foreign policy, defense, and economy – as a strategy for world peace. This union of democracies would serve as a model for peaceful and democratic interaction among na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Space Grant College And Fellowship Program
The space-grant colleges are educational institutions in the United States that comprise a network of fifty-two consortia formed for the purpose of outer space-related research. Each consortium is based in one of the fifty states, the District of Columbia, or Puerto Rico, and each consists of multiple independent space-grant institutions, with one of the institutions acting as lead. Similar programs include sea-grant colleges (instituted in 1966) and sun-grant colleges (instituted in 2003). Objectives The program claims the following objectives: * Establish and maintain a national network of universities with interests and capabilities in aeronautics, outer space, and related fields; * Encourage cooperative programs among universities, the aerospace industry, and federal, state, and local governments; * Encourage interdisciplinary training, research, and public service programs related to aerospace; * Recruit and train U.S. citizens, especially women, underrepresented mino ...

Princeton University
Princeton University is a private university, private research university in Princeton, New Jersey. Founded in 1746 in Elizabeth, New Jersey, Elizabeth as the College of New Jersey, Princeton is the List of Colonial Colleges, fourth-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. It is one of the highest-ranked universities in the world. The institution moved to Newark, New Jersey, Newark in 1747, and then to the current site nine years later.

Kretschmann Scalar
In the theory of Lorentzian manifolds, particularly in the context of applications to general relativity, the Kretschmann scalar is a quadratic scalar invariant. It was introduced by Erich Kretschmann. Definition The Kretschmann invariant is : K = R_ \, R^ where R_ is the Riemann curvature tensor (in this equation the Einstein summation convention was used, and it will be used throughout the article). Because it is a sum of squares of tensor components, this is a ''quadratic'' invariant. For the use of a computer algebra system a more detailed writing is meaningful: : K = R_ \, R^ =\sum_^\sum_^3 \sum_^3\sum_^3 R_ \, R^ \text R^ =\sum_^3 g^\,\sum_^3 g^\,\sum_^3 g^\,\sum_^3 g^\, R_. \, Examples For a Schwarzschild black hole of mass M, the Kretschmann scalar is : K = \frac \,. where G is the gravitational constant. For a general FRW spacetime with metric :ds^2 = - \mathrmt^2 + ^2 \left(\frac + r^2 \, \mathrm\theta^2 + r^2 \sin^2 \theta \, \mathrm\varphi^2 \right), the Kr ...

University Of Toronto Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...
