Apparent Paradox
When the properties of Gabriel's Horn were discovered, the fact that the rotation of an infinite curve about the x-axis generates an object of finite volume was considered paradoxical. However, the explanation is that the bounding curve, is simply a special case–just like the simple harmonic series (Σx−1)–for which the successive area 'segments' do not decrease rapidly enough to allow for convergence to a limit. For volume segments however, and in fact for any generally constructed higher degree curve (e.g. y = 1/x1.001), the same is not true and the rate of decrease in the associated series is sufficiently rapid for convergence to a (finite) limiting sum.
The apparent paradox formed part of a great dispute over the nature of infinity involving many of the key thinkers of the time including Thomas Hobbes, John Wallis and Galileo Galilei.

Famous quotes containing the words apparent and/or paradox:
“Has the art of politics no apparent utility? Does it appear to be unqualifiedly ratty, raffish, sordid, obscene, and low down, and its salient virtuosi a gang of unmitigated scoundrels? Then let us not forget its high capacity to soothe and tickle the midriff, its incomparable services as a maker of entertainment.”
—H.L. (Henry Lewis)
“The paradox of education is precisely this—that as one begins to become conscious one begins to examine the society in which he is being educated.”
—James Baldwin (1924–1987)
