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

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.

If I had to come up with something that just came to me, I think growing up in a small town, I want knowledge. I still think today, knowledge is one of the keys.

My mom took me to see Carnal Knowledge and The Wild Bunch and all these kind of movies when I was a kid.

Education is a private matter between the person and the world of knowledge and experience, and has little to do with school or college.

Contention is inseparable from creating knowledge. It is not contention we should try to avoid, but discourses that attempt to suppress contention.

Harvard is first and foremost a university and not a consulting operation, and our job here is to teach and to research and to create knowledge on Asia in conjunction and in cooperation with scholars as well as with political, intellectual, and cultural leaders in Asia.

It was very interesting for me because DNA made music without much technical knowledge at all.

But, in the name of the experimental method and out of our poor knowledge, are we really entitled to claim that everything happens by chance, to the exclusion of all other possibilities?

The greatest gift is the passion for reading. It is cheap, it consoles, it distracts, it excites, it gives you knowledge of the world and experience of a wide kind. It is a moral illumination.

We must develop knowledge optimization initiatives to leverage our key learnings.

When a doctor does go wrong he is the first of criminals. He has nerve and he has knowledge.

There are in fact two things, science and opinion; the former begets knowledge, the later ignorance.

Knowledge is the treasure of a wise man.

We don't focus as much in schools on educational knowledge which requires thinking and application, as we do on acquiring facts.

The man of knowledge must be able not only to love his enemies but also to hate his friends.

The art and science of asking questions is the source of all knowledge.

The benefits of education and of useful knowledge, generally diffused through a community, are essential to the preservation of a free government.

Today knowledge has power. It controls access to opportunity and advancement.

Effective use of Braille is as important to the blind as independent mobility, knowledge in the use of adaptive technology, and the core belief that equality, opportunity and security are truly possible for all people who are blind.

I feel, sometimes, as the renaissance man must have felt in finding new riches at every point and in the certainty that unexplored areas of knowledge and experience await at every turn.

As far as knowledge goes I've come a long way.
