Science does not have a moral dimension. It is like a knife. If you give it to a surgeon or a murderer, each will use it differently.

I have learned to use the word 'impossible' with the greatest caution.

The logistic requirements for a large, elaborate mission to Mars are no greater that those for a minor military operation extending over a limited theatre of war.

For my confirmation, I didn't get a watch and my first pair of long pants, like most Lutheran boys. I got a telescope. My mother thought it would make the best gift.

In this modern world of ours many people seem to think that science has somehow made such religious ideas as immortality untimely or old fashioned. I think science has a real surprise for the skeptics. Science, for instance, tells us that nothing in nature, not even the tiniest particle, can disappear without a trace. Nature does not know extinction. All it knows is transformation. If God applies this fundamental principle to the most minute and insignificant parts of His universe, doesn't it make sense to assume that He applies it to the masterpiece of His creation, the human soul?

Man belongs wherever he wants to go - and he'll do plenty well when he gets there.

Can a physicist visualize an electron? The electron is materially inconceivable and yet, it is so perfectly known through its effects that we use it to illuminate our cities, guide our airlines through the night skies and take the most accurate measurements. What strange rationale makes some physicists accept the inconceivable electrons as real while refusing to accept the reality of a Designer on the ground that they cannot conceive Him?
