Paris of the year 1900 left two landmarks: the?Tour Eiffel,?and David Hilbert's celebrated list of twenty-four mathematical problems presented at a conference opening the new century. Kurt Godel, a logical icon of that time, showed Hilbert's ideal of complete axiomatization of mathematics to be unattainable. The result, of 1931, is called Godel's?incompleteness theorem.
