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

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 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.

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.

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.

In my lifetime I have witnessed far too many miracles to believe in impossibilities, and so I am officially modifying the defini

Luck affects everything. Let your hook be always cast. In the stream where you least expect it there will be fish.

I've instinctively hated the Tories since birth.

Shakespeare's fault is not the greatest into which a poet may fall. It merely indicates a deficiency of taste.

Responsibiliti es gravitate to the man who can shoulder them and the power to him who knows how

It's all about portion control. Grilled fish, a small amount of wild rice and vegetables is a good meal.

I'm one of three brothers.

Perfect kindness acts without thinking of kindness.

Children: a torment and nothing more.

Karma isn't fate. Nor is it a punishment imposed on us by some external agent. We create our own karma. Karma is the result of the choices that we make every moment of every day.
