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.

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

Paradox is the sharpest scalpel in the satchel of science. Nothing concentrates the mind as effectively, regardless of whether it pits two competing theories against each other, or theory against observation, or a compelling mathematical deduction against ordinary common sense.

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?

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

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

The solution of the Monty Hall problem hinges on the concept of information, and more specifically, on the relationship between added information and probability.
