The best computer is a man, and it’s the only one that can be mass-produced by unskilled labor.

Although I know of no reference to Christ ever commenting on scientific work, I do know that He said, "Ye shall know the truth, and the truth shall make you free." Thus I am certain that, were He among us today, Christ would encourage scientific research as modern man's most noble striving to comprehend and admire His Father's handiwork. The universe as revealed through scientific inquiry is the living witness that God has indeed been at work.

Everybody knows what the moon is, everybody knows what this decade is, and everybody can tell a live astronaut who returned from the moon from one who didn't

In order for us to use the very best judgment possible in spending the taxpayer's money intelligently, we just have to do a certain amount of this research and development work ourselves.

It is in scientific honesty that I endorse the presentation of alternative theories for the origin of the universe, life and man in the science classroom. It would be an error to overlook the possibility that the universe was planned rather than happening by chance.

Man is not made for space. But with the help of biologists and medical doctors, he can be prepared and accommodated.
