Antimatter is not a source of energy for us, it's a method of storing energy, compact but inefficient.

The factor most ignored in discussing interstellar flight is the kinetic energy that must be invested in the ship to make its tons of matter move at a substantial fraction of the speed of light.

Antimatter is not a source of energy for us, it's a method of storing energy, compact but inefficient.

If interstellar travel is as time- or energy- demanding as the above figures indicate, it is far from obvious what the motive for colonization might be.

No one can deny the excitement of visiting another world.

Years of science fiction have produced a mindset that it is human destiny to expand from Earth, to the Moon, to Mars, to the stars.

Present annual world energy consumption is about equal to the annihilation energy of 4 tons of matter.

In the past, on Earth, it has largely been to exploit foreign resources and to expand the domestic territory.

It would be a pity if, frustrated by the price of travel, we elected to become a society that never made contact, that never gave SETI a fair chance.

The sun and its retinue of planets drift as a group through the vast gulfs of space that separate the stars.

I didn't know at the time that the energy that I was giving off was like a battle Emcee.

The young people look great on television. They're youthful and have a lot of zip and energy, but when you see them live, they can only do about 20 minutes because they haven't got the training to hold an audience for an hour and a half or so.

It takes a lot more energy to fail than to succeed, since it takes a lot of concentrated energy to hold on to beliefs that don't work.

I try to give positive energy in all my shows.

In modelling, there is no point in trying to prove you have a brain, so why even bother? I'd sooner save the energy for something more meaningful.

I was part of it, and I am still part of it today in terms of what it means to a whole new generation of people who are interested in the enduring energy, achievements, spirit and creativity that exemplified our era.

I always like having kid energy around. I think it's good for a movie, even when you're doing dramatic stuff.

You had to decompress the pressure before the race. I taught my heart to relax. I lay down before the race. It gave me more energy just before the race.

As long as I had easy access to psychedelics at the government-sponsored research project, most of my energy went into psychedelic sessions.

You can have anything you want if you want it desperately enough. You must want it with an inner exuberance that erupts through the skin and joins the energy that created the world.

Nerves provide me with energy... It's when I don't have them, when I feel at ease, that's when I get worried.

Electric cars aren't pollution-free; they have to get their energy from somewhere.

When I see someone who is starved, they don't look alert. They don't have boundless energy. If you're too skinny, it looks like you're near death.

Why is it so painful to watch a person sink? Because there is something unnatural in it, for nature demands personal progress, evolution, and every backward step means wasted energy.

Comedy is so hard; it's so much harder than drama. The pacing of it, the energy of it.

If for no other reason than the energy crisis now facing this country, the federal government should be eager to become partners with us in rebuilding our city.

It takes a lot of energy to teach.

Any long work in which poetry is persistent, be it epic or drama or narrative, is really a succession of separate poetic experiences governed into a related whole by an energy distinct from that which evoked them.

I believe that the average guy in the street will give up a great deal, if he really understands the cost of not giving it up. In fact, we may find that, while we're drastically cutting our energy consumption, we're actually raising our standard of living.

Life must be considered sui generis; it is not a form of energy, nor can it be expressed in terms of something else.

Men find it difficult because I've got so much energy and hardly sleep at night, only four or five hours. I wake up in the early hours and potter around.

It is greater than the stars - that moving procession of human energy; greater than the palpitating earth and the things growing thereon.

It is really hard to do comedy; it takes a lot of energy and focus. It's rather like music: It's a lot of hitting notes precisely.

Indeed, as the above calculation indicates, to take full advantage of the memory space available, the ultimate laptop must turn all its matter into energy.

The factor most ignored in discussing interstellar flight is the kinetic energy that must be invested in the ship to make its tons of matter move at a substantial fraction of the speed of light.

Maybe I'm being philosophical and spiritual, but I believe that if you put negative energy out there that that is what will come back.

If the United States is to protect itself from the economic and the political threats created by this excessive dependence, we must reduce our reliance on foreign energy sources and on foreign oil as quickly and as efficiently as possible.
