where A is the amplitude, or displacement, of the wave function and ω is its angular velocity.

Famous quotes containing the words forced, van and/or der:
“There is a mortifying experience in particular, which does not fail to wreak itself also in the general history; I mean “the foolish face of praise,” the forced smile which we put on in company where we do not feel at ease, in answer to conversation which does not interest us. The muscles, not spontaneously moved but moved, by a low usurping wilfulness, grow tight about the outline of the face, with the most disagreeable sensation.”
—Ralph Waldo Emerson (1803–1882)
“One could love reason like an Encyclopaedist and still be favorably inclined toward mysticism. Throughout the ages, up to the eyes of van Gogh, when he looked at a coffee pot or a garden path, mysticism has expanded the human realm by all sorts of threshold experiences.”
—Robert Musil (1880–1942)
“Under the lindens on the heather,
There was our double resting-place.”
—Walther Von Der Vogelweide (1170?–1230?)
