And that because the moving parts are a million times smaller than the ones we're familiar with, they move a million times faster, just as a smaller tuning fork produces a higher pitch than a large one.

In thinking about nanotechnology today, what's most important is understanding where it leads, what nanotechnology will look like after we reach the assembler breakthrough.

The really big difference is that what you make with a molecular machine can be completely precise, down to the tiniest degree of detail that can exist in the world.

On the molecular scale, you find it's reasonable to have a machine that does a million steps per second, a mechanical system that works at computer speeds.

And that because the moving parts are a million times smaller than the ones we're familiar with, they move a million times faster, just as a smaller tuning fork produces a higher pitch than a large one.

Protein engineering is a technology of molecular machines - of molecular machines that are part of replicators - and so it comes from an area that already raises some of the issues that nanotechnology will raise.

Today we have big, crude instruments guided by intelligent surgeons, and we have little, stupid molecules of drugs that get dumped into the body, diffuse around and interfere with things as best they can. At present, medicine is unable to heal anything.

After realizing that we would eventually be able to build molecular machines that could arrange atoms to form virtually any pattern that we wanted, I saw that an awful lot of consequences followed from that.

You can find academic and industrial groups doing some relevant work, but there isn't a focus on building complex molecular systems. In that respect, Japan is first, Europe is second, and we're third.

It's a lot easier to see, at least in some cases, what the long-term limits of the possible will be, because they depend on natural law. But it's much harder to see just what path we will follow in heading toward those limits.

The other advantage is that in conventional manufacturing processes, it takes a long time for a factory to produce an amount of product equal to its own weight. With molecular machines, the time required would be something more like a minute.

Likewise nanotechnology will, once it gets under way, depend on the tools we have then and our ability to use them, and not on the steps that got us there.

But if we can manage it so people don't have things forced on them that they don't want, I think there's every reason to believe things can settle out in a situation that is recognizably better than the one we're stuck in today.

My work at MIT had focused on what we could build in space once we had inexpensive space transportation and industrial facilities in orbit. And this led to various sorts of work in space development.

My greatest concern is that the emergence of this technology without the appropriate public attention and international controls could lead to an unstable arms race.

If you take all the factories in the world today, they could make all the parts necessary to build more factories like themselves. So, in a sense, we have a self-replicating industrial system today, but it would take a tremendous effort to copy what we already have.

I've encountered a lot of people who sound like critics but very few who have substantive criticisms. There is a lot of skepticism, but it seems to be more a matter of inertia than it is of people having some real reason for thinking something else.

But while doing that I'd been following a variety of fields in science and technology, including the work in molecular biology, genetic engineering, and so forth.

An international race in the relevant technologies is getting under way at this point, not necessarily with an understanding of where that race leads in the long run, but strongly motivated by the short-term payoffs.

The basic parts, the start-up molecules, can be supplied in abundance and don't have to be made by some elaborate process. That immediately makes things simpler.

Any powerful technology can be abused.

I had been impressed by the fact that biological systems were based on molecular machines and that we were learning to design and build these sorts of things.

In a sense, artificial intelligence will be the ultimate tool because it will help us build all possible tools.

When you live your life with an appreciation of coincidences and their meanings, you connect with the underlying field of infinite possibilities.

Often, when I want to consult my impulses, I cannot find them.

Every city and town in America would be bankrupt if they kept their books the way private-sector companies keep their books - because of the obligation cities and towns have taken upon themselves to provide health care for their retirees.

I want to stretch myself as an actor.

You know, I always think of myself as sort of ready for every criticism.

I think I have a dualistic nature.

My mother and father are still together after forty something years. I lived in one place till I was 6. I lived in another place from when I was 6 till I was 17.

Animation had been done before, but stories were never told.

New York is my favorite city in the world.

I'm only 5 ft. 7 in. tall, and for modelling, that's small, so I wasn't getting signed, but I kept on pushing.

What the iPad does is it opens people's minds to a new way of doing things. They're actually thirsting for it.

Nights through dreams tell the myths forgotten by the day.

The imaginations which people have of one another are the solid facts of society.

We shall not be well so long as we love and admire anything more than we love and admire God.

For these reasons, women tend to rely more heavily on Social Security in their retirement than do men.

Great minds have purposes, others have wishes.

I feel like Ive started a new chapter in my life and I need to leave the past behind.

Stop. Revive. Survive.

I'm not in the news business and won't tell people how to do their job. I'd like to restore trust in the news business, though, and feel that restoring fact-checking will really help. News business realities mean that such fact-checking has to be practical, it has to be fast and cheap.

AppStudio is a native app builder that allows you to build the app and automatically deploy it on Android, iPhone, and Windows. It lets you design it once and then implement it anywhere.

Even though there are plenty of fish in the sea you are without a doubt the perfect fit for me.

I've been writing songs since I was at least 20. That's what I wanted to do before I became a model.

To believe in God is impossible not to believe in Him is absurd.

Cosmetics is a boon to every woman but a girls best beauty aid is still a near sighted man.
