An electron is real; a probability is not.

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.

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

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

As every bookie knows instinctively, a number such as reliability - a qualitative rather than a quantitative measure - is needed to make the valuation of information practically useful.

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