Contexto: 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.

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

“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.”

“Time has been called God's way of making sure that everything doesn't happen at once. In the same spirit, noise is Nature's way of making sure that we don't find out everything that happens. Noise, in short, is the protector of information.”

von Baeyer did not originate the quip about time, which dates back at least as far as the 1929 book "The Man Who Mastered Time" by Ray Cummings, where it appears on p. 1 http://books.google.com/books?id=YdZEAAAAYAAJ&q=%22everything+from+happening+at+once%22#search_anchor.

“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.”

“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?”

“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.”
