An electron is real; a probability is not.

Information gently but relentlessly drizzles down on us in an invisible, impalpable electric rain.

We don't know what energy is, any more than we know what information is, but as a now robust scientific concept we can describe it in precise mathematical terms, and as a commodity we can measure, market, regulate and tax it.

Both induction and deduction, reasoning from the particular and the general, and back again from the universal to the specific, form the essence to scientific thinking.

Time has been called God's way of making sure that everything doesn't happen at once. In the same spirit, noise is Nature's way of making sure that we don't find out everything that happens. Noise, in short, is the protector of information.

In fact, an information theory that leaves out the issue of noise turns out to have no content.

If quantum communication and quantum computation are to flourish, a new information theory will have to be developed.
