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.

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

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

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 of understanding them; and when you have succeeded in doing that, put the whole thing back together again.

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

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

Claude Shannon, the founder of information theory, invented a way to measure 'the amount of information' in a message without defining the word 'information' itself, nor even addressing the question of the meaning of the message.
