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

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

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

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

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.

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