Basic Theory
As distinct from a quantity of heat, temperature may be viewed as a measure of a quality of a body or of heat. The quality is called hotness by some writers.
When two systems are at the same temperature, no net heat transfer occurs spontanteously, by conduction or radiation, between them. When a temperature difference does exist, and there is a thermally conductive or radiative connection between them, there is spontaneous heat transfer from the warmer system to the colder system, until they are at mutual thermal equilibrium. Heat transfer occurs by conduction or by thermal radiation.
Experimental physicists, for example Galileo and Newton, found that there are indefinitely many empirical temperature scales.

Famous quotes containing the words theory and/or basic:
“There is in him, hidden deep-down, a great instinctive artist, and hence the makings of an aristocrat. In his muddled way, held back by the manacles of his race and time, and his steps made uncertain by a guiding theory which too often eludes his own comprehension, he yet manages to produce works of unquestionable beauty and authority, and to interpret life in a manner that is poignant and illuminating.”
—H.L. (Henry Lewis)
“The basic essential of a great actor is that he loves himself in acting.”
—Charlie Chaplin (1889–1977)
