Quanah Parker (1845-1911) was a leader of the Comanche people during the difficult transition period from free-ranging life on the southern plains to the settled ways of reservation life. He became an influential negotiator with government...

Quantitative analysis involves measuring the proportions of known components in a mixture. Whereas qualitative analysis involves identifying what materials are present in a sample (quality), quantitative analysis involves determining how m...

Quantitative traits are those that vary continuously. This is in contrast to qualitative traits, in which the phenotype is discrete and can take on one of only a few different values. Examples of quantitative traits include height, weight,...

In physics, a discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property. Light, for example, which appears in some respects as a continuous electromagnetic wave, on the submicroscopic level is emitte...

Theory that describes the action of the strong force. The strong force acts only on certain particles, principally quarks that are bound together in the protons and neutrons of the atomic nucleus, as well as in less stable, more exotic for...

Physicists believe in a unified description of the world. The complex structures and phenomena we observe today, in every physical system, have at their heart one set of conceptually simple rules, although the mathematical formalism can be...

Theory that brings quantum mechanics and special relativity together to account for subatomic phenomena. In particular, the interactions of subatomic particles are described in terms of their interactions with fields, such as the electroma...

Quantum Leap was a science fiction television program which ran from 1989 to 1993 on NBC starring Scott Bakula and Dean Stockwell . Contents 1 Repeated quotes 2 Season 1 2.1 Genesis [1.01] 2.2 Star-Crossed [1.02] 2.3 The Right Hand of God ...

Branch of mathematical physics that deals with atomic and subatomic systems. It is concerned with phenomena that are so small-scale that they cannot be described in classical terms, and it is formulated entirely in terms of statistical pro...

A quantum state is the condition a quantum mechanical system is in. The state is usually described by a wave function. It is different from classical states of systems in that the quantum system has separate, discrete levels, whereas the s...

Anger may repast with thee for an hour, but not repose for a night; the continuance of anger is hatred, the continuance of hatred turns malice....

Lloyd Albert Quarterman was one of only a handful of African Americans to work on the "Manhattan Project ," the team that developed the first atom bomb in the 1940s. He was also noted as a research chemist who specialized in fluoride chemi...

The solution of the cubic and quartic equations was one of the major achievements of Renaissance algebra. The publication of the results in Girolamo Cardano's book The Great Art brought charges that Cardano had broken his promise t...

any of a class of rare cosmic objects of high luminosity that often have strong radio emission that is observed at great distances. These objects are also called QSOs, which stands for “quasi-stellar objects.” The bright emitti...

QUATERNITY, or a fourfold structure (together with its multiples—eightfold, twelvefold, etc.), expresses symbolically the nature of the divine and, by extension, describes the structure of the world that mirrors that divinity. Like ...

Of course, Quebec-bashing is nothing new for the anglophone press, but it is so widespread these days that one wonders if it hasn't become a natural and acceptable expression of Canadian patriotism. [1] Michel David , journalist for Le Dev...

Many people to this day have no knowledge to as how important French Canadians are to our history. Many do not realize that Quebec has been trying to become a nation on their own and to be distinguished as their own colony. In this essay I ...

In every woman there is a Queen. Speak to the Queen and the Queen will answer. The children will not leave unless I do. I shall not leave unless their father does, and the King will not leave the country in any circumstances whatever. Thin...
