“If we continue at this leisurly pace, we will have to pass Russian customs when we land on the moon.”

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.

There is just one thing I can promise you about the outer-space program – your tax-dollar will go further.

The same forces of nature which enable us to fly to the stars, enable us also to destroy our star.

Crash programs fail because they are based on theory that, with nine women pregnant, you can get a baby in a month.

To simply dismiss the concept of God as being unscientific is to violate the very objectivity of science itself.

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.

Don’t tell me that man doesn’t belong out there. Man belongs wherever he wants to go – and he’ll do plenty well when he gets there.

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.

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

It was very successful, but it fell on the wrong planet.

Looking back, nothing seems so simple than a utopian vision realised.

I find it as difficult to understand a scientist who does not acknowledge the presence of a superior rationality behind the existence of the universe as it is to comprehend a theologian who would deny the advances of science.

I believe in an immortal soul. Science has proved that nothing disintegrates into nothingness. Life and soul, therefore, cannot disintegrate into nothingness, and so are immortal.

The greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.

If we were to start today on an organized and well-supported space program I believe a practical passenger rocket can be built and tested within ten years.

I’m convinced that before the year 2000 is over, the first child will have been born on the moon.

I’m just not one of those naturally funny, relaxed actors who enjoy the spotlight and are so good at it.

Everyone has been really accepting and brought me into the family. I had a lot of fun shooting it.

Joy is a big stress buster too. Measure your success by how much fun you’re having.

I suppose directing on set is the most fun because it’s a good crack and you feel you’re on the battlefield whereas writing is a fairly solitary undertaking.

I had fun to be a little bit of a nerd.

I would describe myself as emotional and highly strung. If something upsets me, it really upsets me. If something makes me angry, I get really angry. But it’s all very upfront. I can’t hide it. I’m also loyal and I hope I’m fun.

It was great fun. We had gone on tour in between the sessions and reconnected with the audience and got a lot of energy back from them, a lot of positive energy.

Summer means happy times and good sunshine. It means going to the beach, going to Disneyland, having fun.
