Swiss Cheese (mathematics)

In mathematics, a Swiss cheese is a compact subset of the complex plane obtained by removing from a closed disc some countable union of open discs. More generally, a Swiss cheese may be all or part of Euclidean space Rn – or of an even more complicated manifold – with "holes" in it.

Famous quotes containing the words swiss and/or cheese:

    “Which is more important to you, your field or your children?” the department head asked. She replied, “That’s like asking me if I could walk better if you amputated my right leg or my left leg.”
    —Anonymous Parent. As quoted in Women and the Work Family Dilemma, by Deborah J. Swiss and Judith P. Walker, ch. 2 (1993)

    I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.
    Edward T. Hall (b. 1914)
