Underneath the shifting appearances of the world as perceived by our unreliable senses, is there, or is there not, a bedrock of objective reality?.

Numbers instill a feeling for the lie of the land, and furnish grist for the mathematical mill that is the physicist's principal tool..

In order to understand information, we must define it; bit in order to define it, we must first understand it. Where to start?.

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

For generations, field guides to plants and animals have sharpened the pleasure of seeing by opening our minds to understanding. Now John Adam has fi….

As every bookie knows instinctively, a number such as reliability - a qualitative rather than a quantitative measure - is needed to make the valuatio….

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 w….

If the intensity of the material world is plotted along the horizontal axis, and the response of the human mind is on the vertical, the relation betw….

Entropy is not about speeds or positions of particles, the way temperature and pressure and volume are, but about our lack of information..

The problem of defining exactly what is meant by the signal velocity, which cropped up as long ago as 1907, has not been solved..

The switch from 'steam engines' to 'heat engines' signals the transition from engineering practice to theoretical science..

An electron is real; a probability is not..

Science has taught us that what we see and touch is not what is really there..

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 mathema….

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

To put it one way, a collection of Shakespeare's plays is richer than a phone book that uses the same number of letters; to put it another, the essen….

Paradox is the sharpest scalpel in the satchel of science. Nothing concentrates the mind as effectively, regardless of whether it pits two competing ….

This is not what I thought physics was about when I started out: I learned that the idea is to explain nature in terms of clearly understood mathemat….

If you don't understand something, break it apart; reduce it to its components. Since they are simpler than the whole,you have a much better chance o….

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

The smell of subjectivity clings to the mechanical definition of complexity as stubbornly as it sticks to the definition of information..
