The Constant Nature of Science: "There is no logical necessity for a universe that obeys rules, let alone one that abides by the rules of mathematics. The speed of light measures the same 186,000 miles per second, no matter if the light comes from a child's flashlight or a star that's galaxies away. Mathematically, there is an exact speed of light that doesn't change.
Physicist Eugene Wigner confesses that the mathematical underpinning of nature "is something bordering on the mysterious and there is no rational explanation for it."3 Richard Feynman, a Nobel Prize winner for quantum electrodynamics, said, "Why nature is mathematical is a mystery...The fact that there are rules at all is a kind of miracle."4
This astonishment springs from the recognition that the universe doesn't have to behave this way. It is easy to imagine a universe in which conditions change unpredictably from instant to instant, or even a universe in which things pop in and out of existence. Instead, scientists cling to their long-held faith in the fundamental rationality of the cosmos.
Physicist Paul C. Davies comments, "...to be a scientist, you had to have faith that the universe is governed by dependable, immutable, absolute, universal, mathematical laws of an unspecified origin. You've got to believe that these laws won't fail, that we won't wake up tomorrow to find heat flowing from cold to hot, or the speed of light changing by the hour. Over the years I have often asked my physicist colleagues why the laws of physics are what they are? ...The favorite reply is, 'There is no reason they are what they are--they just are.'"5"
