It is credited to the Soviet mathematician Andrey Nikolaevich Kolmogorov.

Famous quotes containing the words extension and/or theorem:

    We are now a nation of people in daily contact with strangers. Thanks to mass transportation, school administrators and teachers often live many miles from the neighborhood schoolhouse. They are no longer in daily informal contact with parents, ministers, and other institution leaders . . . [and are] no longer a natural extension of parental authority.
    James P. Comer (20th century)

    To insure the adoration of a theorem for any length of time, faith is not enough, a police force is needed as well.
    Albert Camus (1913–1960)
