Complex Manifold/k%C3%A4hler and Calabi-yau Manifolds

Famous quotes containing the words complex and/or manifold:

“In ordinary speech the words perception and sensation tend to be used interchangeably, but the psychologist distinguishes. Sensations are the items of consciousness—a color, a weight, a texture—that we tend to think of as simple and single. Perceptions are complex affairs that embrace sensation together with other, associated or revived contents of the mind, including emotions.”
—Jacques Barzun (b. 1907)

“Civilisation is hooped together, brought
Under a rule, under the semblance of peace
By manifold illusion....”
—William Butler Yeats (1865–1939)
