Donald Knuth's Annual Christmas Lecture | Stanford Center for Professional Development
A Conjecture That Had To Be True A few months ago, the speaker did some extensive calculations relating to a curious problem in combinatorial geometry; and the resulting numbers satisfied an amazing formula. Although this formula was known to be true only in the five or six smallest cases of the problem, it was impossible to imagine a decent world in which the formula would not hold universally.
