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.

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.

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?

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

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

The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.

Thinking of the universe as a computer is controversial.

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

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.

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.

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.

It must be conceded by those who admit the authority of Scripture (such only he is addressing) that from the decision of the word of God there can be no appeal.

Don't you know that when you sleep with someone, your body makes a promise whether you do or not.

Young blood must have its course, lad, and every dog its day.

Since the universe is infinite, that inspires me with endless ideas.

Samadhi is the absorption of God. There's no sense of time, place or condition.

Men's second childhood begins when a woman gets a hold of him.

I suddenly realized that a bunch of my friends needed babysitters and vowed to start screening my calls.

Well, India is a country of nonsense

We need the courage to start and continue what we should do, and courage to stop what we shouldn't do.

I think that personality traits that come through when somebody is really sincere is what makes them beautiful.
