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?
The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.
When you zap things with light to build quantum computers, you're hacking existing systems. You're hijacking the computation that's already happening in the universe, just like a hacker takes over someone else's computer.
If the clockwork universe equated the human body with the mechanics of the clock, the digital universe now equates human consciousness with the processing of the computer. We joke that things don't compute, that we need a reboot, or that our memory has been wiped.
Mathematics is much more than computation with pencil and a paper and getting answers to routine exercises. In fact, it can easily be argued that computation, such as doing long division, is not mathematics at all. Calculators can do the same thing and calculators can only calculate they cannot do mathematics.
You can't *discover* that the brain is a digital computer. You can only *interpret* the brain as a digital computer.
(Acting) is an extension of life. How you're capable of performing in your life, that's how you're capable of performing on screen.
The idea of the Universe being ruled by that marvelous old gentleman, is no longer plausible. It isn't that anybody has disproved it, but it just somehow doesn't go with the vast infinitude of the Universe.
We couldn't build quantum computers unless the universe were quantum and computing. We can build such machines because the universe is storing and processing information in the quantum realm. When we build quantum computers, we're hijacking that underlying computation in order to make it do things we want: little and/or/not calculations. We're hacking into the universe.
Your positions on EVERYTHING are based on the story you tell yourself and not some universal fact from the universal fact database.
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.
But biology and computer science - life and computation - are related. I am confident that at their interface great discoveries await those who seek them.
If you think of your life as a kind of computation, it's quite abundantly clear that there's not going to be a final answer and there won't be anything particularly wonderful about having the computation halt!
With the advent of computing, human invention crossed a threshold into a world different from everything that came before. The computer is the universal machine almost by definition, machine-of-all-trades, capable of accomplishing or simulating just about any task that can be logically defined.
The reason is that everyone has trouble accepting the fact that he will disappear unheard of and unnoticed in an indifferent universe, and everyone wants to make himself into a universe of words before it's too late. Once the writer in every individual comes to life (and that time is not far off), we are in for an age of universal deafness and lack of understanding.
There is no evolutionary pressure to create minds capable of forming sciences; it just happened. Evolutionary pressure has not led to higher rates of reproduction for people capable of solving scientific problems or creating new scientific ideas. So if, in fact, the science-forming capacities evolved for other reasons, it would not be too surprising if those particular structures that have developed proved to be rather special in their nature, reflecting the contingencies of their evolution or the working of physical law.
