Last time, we met Pierre de Fermat, the amateur genius who invented number theory in his spare
time. We saw his famous last theorem and his correspondence with Pascal that founded
probability theory. Welcome back to Men of Mathematics. Today we meet Fermat's correspondent,
Blais Pascal, who lived more intensely in 39 years than most people live in 90.
mathematician, physicist, inventor, philosopher, theologian, Pascal was all of these, sometimes all at once.
