Density Functional Theory/thomas%e2%80%93fermi Model

Famous quotes containing the words functional, theory and/or model:

    Indigenous to Minnesota, and almost completely ignored by its people, are the stark, unornamented, functional clusters of concrete—Minnesota’s grain elevators. These may be said to express unconsciously all the principles of modernism, being built for use only, with little regard for the tenets of esthetic design.
    —Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)

    Don’t confuse hypothesis and theory. The former is a possible explanation; the latter, the correct one. The establishment of theory is the very purpose of science.
    Martin H. Fischer (1879–1962)

    The Battle of Waterloo is a work of art with tension and drama with its unceasing change from hope to fear and back again, change which suddenly dissolves into a moment of extreme catastrophe, a model tragedy because the fate of Europe was determined within this individual fate.
    Stefan Zweig (18811942)
