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

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.

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.

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

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.

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