Quantum mechanics is weird. I don't understand it. Just live with it. You don't have to understand the nature of things in order to build cool devices.

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.

Meaning is like pornography, you know it when you see it.

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?

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.

When it comes to their capacity to screw things up, computers are becoming more human every day.

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.
