Elliot Quincy Adams
Elliot Quincy Adams (September 13, 1888 – March 12, 1971) was an American scientist. Chemist Gilbert N. Lewis remarked that "the two most profound scientific minds, among the people he had known, were those of E liotQ Adams and Albert Einstein."D S Tarbell, "Elliot Quincy Adams (1888-1971): From dipolar ions to fluorescent lights." ''Journal of Chemical Education,'' 67:7-8 (1990). Adams was the son of Edward Perkins and Etta Medora (Elliot) Adams, and a descendant of John Adams, circa 1650 from Cambridge, Massachusetts. He graduated from Medford High School in Medford, Massachusetts, and attended the Massachusetts Institute of Technology, studying chemical engineering under Gilbert N. Lewis (1875–1946), and in 1909 earned his bachelor's degree in chemical engineering. After graduation, Adams took a position with the General Electric Research Laboratory in Schenectady, New York, where he worked with Irving Langmuir on problems dealing with heat transfer. In 1912 Adams supplie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Of America
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau.

CIELAB
The CIELAB color space, also referred to as ''L*a*b*'' , is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976. (Referring to CIELAB as "Lab" without asterisks should be avoided to prevent confusion with Hunter Lab). It expresses color as three values: ''L*'' for perceptual lightness and ''a*'' and ''b*'' for the four unique colors of human vision: red, green, blue and yellow. CIELAB was intended as a perceptually uniform space, where a given numerical change corresponds to a similar perceived change in color. While the LAB space is not truly perceptually uniform, it nevertheless is useful in industry for detecting small differences in color. Like the CIEXYZ space it derives from, CIELAB color space is a device-independent, "standard observer" model. The colors it defines are not relative to any particular device such as a computer monitor or a printer, but instead relate to the CIE standard observer which is an averaging of th ...

Boy Scouts Of America
The Boy Scouts of America (BSA, colloquially the Boy Scouts) is one of the largest scouting organizations and one of the largest List of youth organizations, youth organizations in the United States, with about 1.2 million youth participants. The BSA was founded in 1910, and since then, about 110 million Americans have participated in BSA programs. BSA is part of the international Scout Movement and became a founding member organization of the World Organization of the Scout Movement in 1922. The stated mission of the Boy Scouts of America is to "prepare young people to make ethical and moral choices over their lifetimes by instilling in them the values of the Scout Oath and Law." Youth are trained in responsible citizenship, character development, and self-reliance through participation in a wide range of outdoor activities, educational programs, and, at older age levels, career-oriented programs in partnership with community organizations. For younger members, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Beaver Award
The Silver Beaver Award is the council-level distinguished service award of the Boy Scouts of America. Upon nomination by their local Scout council and with the approval of the National Court of Honor, recipients of this award are registered adult leaders who have made an impact on the lives of youth through service given to the council. The Silver Beaver is an award given to those who implement the Scouting program and perform community service through hard work, self-sacrifice, dedication, and many years of service. It is given to those who do not seek it. Award The medal consists of a silver beaver pendant suspended from a blue and white ribbon worn around the neck. Recipients may wear the corresponding square knot, with a white strand over a blue strand, on the BSA uniform. There is also a lapel pin authorized and available for civilian wear. Using the United States Military as the model, silver awards are the highest awards in the BSA. History The Silver Beaver was introd ...

American Physical Society
The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. The society publishes more than a dozen scientific journals, including the prestigious ''Physical Review'' and '' Physical Review Letters'', and organizes more than twenty science meetings each year. APS is a member society of the American Institute of Physics. Since January 2021 the organization has been led by chief executive officer Jonathan Bagger. History The American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", and in one way or another the APS has been at that task ever since.

Chroma (color)
In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), chroma (color intensity), and value (lightness). It was created by Professor Albert H. Munsell in the first decade of the 20th century and adopted by the United States Department of Agriculture (USDA) as the official color system for soil research in the 1930s. Several earlier color order systems had placed colors into a three-dimensional color solid of one form or another, but Munsell was the first to separate hue, value, and chroma into perceptually uniform and independent dimensions, and he was the first to illustrate the colors systematically in three-dimensional space. Munsell's system, particularly the later renotations, is based on rigorous measurements of human subjects' visual responses to color, putting it on a firm experimental scientific basis. Because of this basis in human visual perception, Munsell's system has outlasted its co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CIE 1931 Color Space
The CIE 1931 color spaces are the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiologically perceived colors in human color vision. The mathematical relationships that define these color spaces are essential tools for color management, important when dealing with color inks, illuminated displays, and recording devices such as digital cameras. The system was designed in 1931 by the ''"Commission Internationale de l'éclairage"'', known in English as the International Commission on Illumination. The CIE 1931 RGB color space and CIE 1931 XYZ color space were created by the International Commission on Illumination (CIE) in 1931. They resulted from a series of experiments done in the late 1920s by William David Wright using ten observers and John Guild using seven observers. The experimental results were combined into the specification of the CIE RGB color space, from which the CIE XYZ color space was deriv ...
