Bits and Beyond...
FERMAT'S LAST THEOREM Fermat's Last Theorem is one of the famous problems of Mathematics.
This problem was formulated by Pierre de Fermat before his death. He
was a lawyer by profession, who enjoyed spending his leisure time studying
mathematics. This problem when restated is: If n is a whole number greater than 2, then there are no whole numbers
a, b, c such that an + bn = cn. For over 350 years, the proof or disproof of this conjecture occupied the minds of
mathematicians. In fact, several
more important or useful theories were derived in the effort to prove this
theorem. It was in the recent years that Andrew Wiles, a
mathematician from Princeton, proved this theory in a work consisting of
more than 200 pages.
