“In order to be irreplaceable one must always be different.”

Science is the only basis of hope for human future.

The important thing is not what one is born with, but what they do with the gift of life.

There is a season for everything.

Science may have found a cure for most evils, but it has found no remedy for the worst of them all: the apathy of human beings.

Education is what remains after one has forgotten what one has learned in school.

Be kind whenever possible.
