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 between the two is represented by the logarithmic curve. Could this rule provide a clue to the relationship between the objective measure of information, and our subjective perception of it?

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

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.

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

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 mathematical laws; but perhaps comparisons are the best we can hope for.

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