If the world is a computer, life is an algorithm Science News - June 26, 2014

Today a fair number of scientists regard nature as a computer. Describing the universe as a computer does make a certain amount of sense. Laws governing how the universe works are expressed in mathematical formulas. You use those formulas to compute what nature will do, such as when the moon will position itself for the next solar eclipse. Just as you do a digital computation to figure out where the moon will be, nature simply conducts a real-time analog computation of its own that puts the moon where it is supposed to be.
