The amount of information that can be stored by the ultimate laptop, 10 to the 31st bits, is much higher than the 10 to the 10th bits stored on current laptops.

Nothing in life is certain except death, taxes and the second law of thermodynamics.

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.

According to the standard model billions of years ago some little quantum fluctuation, perhaps a slightly lower density of matter, maybe right where we're sitting right now, caused our galaxy to start collapsing around here.

In this metaphor we actually have a picture of the computational universe, a metaphor which I hope to make scientifically precise as part of a research program.

If you wanted to build the most powerful computer you could, you can't do better than including everything in the universe that's potentially available.

At some point, Moore's law will break down.

All physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of.

I would suggest, merely as a metaphor here, but also as the basis for a scientific program to investigate the computational capacity of the universe, that this is also a reasonable explanation for why the universe is complex.

Computers are famous for being able to do complicated things starting from simple programs.

In order to figure out how to make atoms compute, you have to learn how to speak their language and to understand how they process information under normal circumstances.

Merely by existing and evolving in time - by existing - any physical system registers information, and by evolving in time it transforms or processes that information.

One of the things that I've been doing recently in my scientific research is to ask this question: Is the universe actually capable of performing things like digital computations?

We have a picture for how complexity arises, because if the universe is computationally capable, maybe we shouldn't be so surprised that things are so entirely out of control.

Something else has happened with computers.

Of course, one way of thinking about all of life and civilization is as being about how the world registers and processes information. Certainly that's what sex is about; that's what history is about.

It's also a reasonable scientific program to look at the dynamics of the standard model and to try to prove from that dynamics that it is computationally capable.

Thinking of the universe as a computer is controversial.

Similarly, another famous little quantum fluctuation that programs you is the exact configuration of your DNA.

I have not proved that the universe is, in fact, a digital computer and that it's capable of performing universal computation, but it's plausible that it is.

Every physical system registers information, and just by evolving in time, by doing its thing, it changes that information, transforms that information, or, if you like, processes that information.

There are considerable advantages to using many degrees of freedom to store information, stability and controllability being perhaps the most important.

If you take a more Darwinian point of view the dynamics of the universe are such that as the universe evolved in time, complex systems arose out of the natural dynamics of the universe.

The amount of information that can be stored by the ultimate laptop, 10 to the 31st bits, is much higher than the 10 to the 10th bits stored on current laptops.

Science consists exactly of those forms of knowledge that can be verified and duplicated by anybody.

Another feature that everybody notices about the universe is that it's complex.

Instead of having to be a member of the Royal Society to do science, the way you had to be in England in the 17th, 18th, centuries today pretty much anybody who wants to do it can, and the information that they need to do it is there.

What's happened with society is that we have created these devices, computers, which already can register and process huge amounts of information, which is a significant fraction of the amount of information that human beings themselves, as a species, can process.

Of course, not everybody's willing to go out and do the experiments, but for the people who are willing to go out and do that, - if the experiments don't work, then it means it's not science.

Young people discovering their sexuality must know they walk with a strong tradition and that they are not alone. They have a right to information without being pressured.

But in the first Gulf war the United Kingdom was not under any threat from Iraq, and is still less so in the second one. Then there is no justification for obstructing freedom of information, particularly as nations have a right to know what their soldiers are being used for.

And they talk about their bona fide doctors. They have a list of doctors that signed affidavits from looking at a picture of Terry. That's where they get their information from, by looking at a picture.

Since I'm allergic to various things, the army wouldn't accept me during the war, and I got into the Office of War Information, which sent music to Europe.

Actually the copies of characters is something I don't particularly like to talk about in articles but just for your information, most characters there's only one.

But the Congress has made the determination that certain kinds of information can be protected even though the American people may want to have access to information.

Although Customs and Border Protection analyzes cargo and other information to target specific shipments for closer inspection, it still physically inspects only a small fraction of the containers under its purview.

I have a tendency to be lucky and make the right choices based on limited information.

I would never jeopardize classified information to be brought out to the public. This information is all open source. There is no reason to worry about classification. It is simply an attempt by bureaucrats to cover their rear ends.

For me, having a child is a really great responsibility because you've got something there that is depending on you for information and love until a certain age when it goes to school.

People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people - and that social norm is just something that has evolved over time.

First, the security and privacy of sensitive taxpayer information is absolutely essential.

Information, usually seen as the precondition of debate, is better understood as its by-product.

Because of Watergate in part, I am kind of a magnet for calls and information and suggestions.

With respect to the FBI, they had problems communicating in a vertical way, within the FBI itself, so that information of importance could get pushed up to those who were decision-makers.

It is evident that one cannot say anything demonstrable about the problem before having resolved these preliminary questions, and yet we hardly possess the necessary information to solve some of them.

We finally found out the technique of separating and getting information about where every train would be at any moment. Of course, I went over budget many times, because - as you go along - some things improved, and you get better ideas.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.

The Bush administration also was not straightforward about the intelligence it had, releasing tenuous information that fit its goal of attacking Iraq. I feel deceived.

Success, for me, is being able to provide information that will help to change someone's life positively.
