quantum chromodynamics (QCD) (sh) and Clinton, DeWitt (sh)


quantum chromodynamics (QCD) (sh)




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 forms of matter. Quantum chromodynamics has been built on the concept that quarks interact via the strong force because they carry a form of "strong charge," which has been given the name "colour." The three types of charge are called red, green, and blue, in analogy to the primary colours of light, though there is no connection with the usual sense of colour.


Clinton, DeWitt (sh)




born March 2, 1769, Little Britain, N.Y.
died Feb. 11, 1828, Albany, N.Y., U.S.

U.S. politician.

A nephew of George Clinton, he practiced law and served as state senator (1798-1802, 1806-11), U.S. senator (1802-03), mayor of New York City (1803-15 except for two annual terms), lieutenant governor (1811-13), and governor (1817-23, 1825-28). He proposed the idea of a canal across New York state, and he oversaw the construction of Erie Canal from 1816 until its opening in 1825. The canal assured the 19th-century development of New York City as the major port of trade with the Midwest.
