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.

Striving for success without hard work is like trying to harvest where you havent planted.

The thing about politicians in Britain is that they are out there, you can lobby them, get close to them, there are loads of ways you can protest against them, and booing is a pretty weak way of doing it.

I'm committed as governor to valuing and nurturing our relationships with our friends to the south.

I truly believe anything is possible if you fully manifest it.

The first two books that I did by myself were long stories in verse. I knew I could do that because I'd written a lot in verse. But, verse stories are hard to sell, so my editor encouraged me to try writing in prose.

The sun the moon the stars the birds the animals the flowers are all proof that a universal power exists.

Try and fit in in a New Zealand playground with an Armagh accent - it doesn't work.

Integrity is telling myself the truth. And honesty istelling the truth to other people.

Those who dream by day are cognizant of many things that escape those who dream only at night.

I'm always looking for something new: a new inspiration, a new philosophy, a new way to look at something, new talent.

I am perfectly happy being his friend in fact I love it... I just have this incredible urge to kiss him that doesnt go away... and this feeling that we would be perfect together.

We learned about gratitude and humility - that so many people had a hand in our success, from the teachers who inspired us to the janitors who kept our school clean... and we were taught to value everyone's contribution and treat everyone with respect.

I am full of energy and life.

If an ordinary person parks outside another ordinary person's house for a week, it's considered stalking. If, however, that person is considered newsworthy, it's perfectly legal for paparazzi to do the same thing.

Vice, by comparison with terrible accidents, has its own peculiar explanation. For, in a way, it does occur in accordance with the rationale of nature, and its occurrence is not, so to speak, useless in relation to the whole world. For otherwise, the good would not exist, either.

To a degree the Greek and Roman mythological heroes are just the first superheroes. They appeal to children for much the same reason. These gods and heroes may have powers but they get angry and they do the wrong thing. They are human too.

An FBI agent ought to be able to surf the net and look for sites that instruct people how to make bombs.

Sometimes you will think you cant take it another day. But if you hang in there one step at a time you will be able to accomplish more than you ever imagine.

The true artist is not proud: he unfortunately sees that art has no limits; he feels darkly how far he is from the goal, and though he may be admired by others, he is sad not to have reached that point to which his better genius only appears as a distant, guiding sun.

Britain is an open and tolerant country, and I will fight with everything I have to keep it so.

The identification of the genes which determine biological phenomena and the study of the control they exert on these phenomena has proven to be the most successful approach to a detailed understanding of the mechanism of biological processes.

I'm not staying away from any genre. I'm trying to get scripts that I like.

I love hiking in the hills not far from my house. I'm invested in my hikes. Sometimes kids go up there and spray-paint over the signs; I've found a biodegradable paint cleaner, and I'll scrub the signs so they're nice and clean.

Elephants have the largest brains of any mammal on the face of the Earth. They are creative, altruistic and kind.
