Banach Stefan. 1892-1945. Polish mathematician who founded modern functional analysis.

"A mathematician is a person who can find analogies between theorems,
a better mathematician is one who can see analogies between proofs and
the best mathematician can notice analogies between theories.
One can imagine that
the ultimate mathematician is one
who can see analogies between analogies."



"Mathematics is the most beautiful and most powerful creation of the human spirit."
