Numbers instill a feeling for the lie of the land, and furnish grist for the mathematical mill that is the physicist's principal tool.

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.

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

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