Hilbert's Paradox of The Grand Hotel

Hilbert's paradox of the Grand Hotel is a veridical paradox (a valid argument with a seemingly absurd conclusion, as opposed to a falsidical paradox, which is a seemingly valid demonstration of an actual contradiction) about infinite sets presented by German mathematician David Hilbert (1862–1943) in the 1920s, meant to illustrate certain counterintuitive properties of infinite sets.

Famous quotes containing the words paradox, grand and/or hotel:

    The conclusion suggested by these arguments might be called the paradox of theorizing. It asserts that if the terms and the general principles of a scientific theory serve their purpose, i. e., if they establish the definite connections among observable phenomena, then they can be dispensed with since any chain of laws and interpretive statements establishing such a connection should then be replaceable by a law which directly links observational antecedents to observational consequents.
    —C.G. (Carl Gustav)

    It is a grand thing to rise in the world. The ambition to do so is the very salt of the earth. It is the parent of all enterprise, and the cause of all improvement.
    Anthony Trollope (1815–1882)

    The hotel was once where things coalesced, where you could meet both townspeople and travelers. Not so in a motel. No matter how you build it, the motel remains the haunt of the quick and dirty, where the only locals are Chamber of Commerce boys every fourth Thursday. Who ever heard the returning traveler exclaim over one of the great motels of the world he stayed in? Motels can be big, but never grand.
    William Least Heat Moon [William Trogdon] (b. 1939)
