   In this talk I will give a very elementary proof of the theorem.  I
   am surprised that no one else has thought of this before.

 \fromSlide{2}{%
 Fermat's Last Theorem says that the equation
 \[
         x^2 + y^2 = z^2
 \]
 has no solution in the set of natural numbers.

   This is not true.  After a lengthy calculation on the department's
   Linux machines, I have verified that within the numerical accuracy
   of the Pentium-4 processor, we have:
 \[
         5000^2 + 12000^2 = 13000^2
