If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.
Budapest, Hungary
It is just as foolish to complain that people are selfish and treacherous as it is to complain that the magnetic field does not increase unless the electric field has a curl. Both are laws of nature.
Young man, in mathematics you don't understand things. You just get used to them.
Life is really simple, but we insist on making it complicated.
Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things.
