History has repeatedly shown that when a new method or material becomes available, new uses for it arise.

France generates a significant part of its energy requirements from fission reactors and these have achieved a perfect safety record. We build ours all differently.

Failure is a learning experience, and the guy who has never failed has never done anything.

There is more He-3 energy on the Moon than we have ever had in the form of fossil fuels on Earth. All we have to do is to go there and get it.

Nuclear fusion of light elements like hydrogen or helium would permit approaching the speed of light. It seems very attractive to refuel your space ships where the fuel is.

Our present nuclear fusion reactors are classified by the methods used to support the nuclear fusion reaction, which takes place at a temperature much hotter than the surface of the Sun.

The 20th Century was the century of Aviation and the century of Globalization. The next century will be the century of Space.

This is no job for a UN committee. It needs the same kind of unwavering dedication and the kinds of people that got us the first nuclear submarine and the first man on the moon.

We need the kind of leadership exemplified by President Kennedy to just do it! But we must do it as good stewards, aggressively exerting control over the moon. We can best do this by going there.

When you buy a gallon of gas, over 60 percent of the energy you pay for goes out the radiator in the form of waste heat? That's why you have a radiator in your car in the first place.

It is clear that the nation that assumes stewardship of the Moon now will inherit stewardship of the galaxy in the coming millennium. I think the USA is ready for that challenge!

Happiness is not a destination but the journey itself.

Our ancient Indian Rishis realized that SPACE is a distinct entity with its own properties and called it AAKASA...The West realized it only when Einstein published his Theory of Relativity....

My job is to play quarterback, and I'm going to do that the best way I know how, because I owe that to my teammates regardless of who is out there on the field with me.

Mmm....she's doomed! You're doomed!! They're all doomed! Notice I didn't specify what kind of doom, so no matter what happens, I predicted it. How very WISE of me.

If you want to stay perfect, you cannot go undefeated with a blemish on your record.

The one way the world hasn't changed: teaching is still the most important job.

As human beings, our only sensible scale of values is one based on lessening the agony of existence.

Life is never going to be perfect, as much as we want it to be, and I have to lead by example.

A human body is associated with six stages of transformation, birth, growth, change, evolution, death and destruction.
