We find ourselves in a bewildering world. We want to makesense of what we see around us and to ask: What is thenature of the universe? What is our place in it and where didit and we come from? Why is it the way it is?
To try to answer these questions we adopt some “worldpicture.” Just as an infinite tower of tortoises supporting the fiatearth is such a picture, so is the theory of superstrings. Bothare theories of the universe, though the latter is much moremathematical and precise than the former. Both theories lackobservational evidence: no one has ever seen a giant tortoisewith the earth on its back, but then, no one has seen asuperstring either. However, the tortoise theory fails to be agood scientific theory because it predicts that people should beable to fall off the edge of the world. This has not been foundto agree with experience, unless that turns out to be theexplanation for the people who are supposed to havedisappeared in the Bermuda Triangle!
The earliest theoretical attempts to describe and explain theuniverse involved the idea that events and natural phenomenawere controlled by spirits with human emotions who acted in avery humanlike and unpredictable manner. These spiritsinhabited natural objects, like rivers and mountains, includingcelestial bodies, like the sun and moon. They had to beplacated and their favor sought in order to ensure the fertilityof the soil and the rotation2 of the seasons. Gradually, however,it must have been noticed that there were certain regularities3:
the sun always rose in the east and set in the west, whetheror not a sacrifice had been made to the sun god. Further, thesun, the moon, and the planets followed precise paths acrossthe sky that could be predicted in advance with considerableaccuracy. The sun and the moon might still be gods, but theywere gods who obeyed strict laws, apparently4 without anyexceptions, if one discounts stories like that of the sun stoppingfor Joshua.
At first, these regularities and laws were obvious only inastronomy and a few other situations. However, as civilizationdeveloped, and particularly in the last 300 years, more andmore regularities and laws were discovered. The success ofthese laws led Laplace at the beginning of the nineteenthcentury to postulate5 scientific determinism; that is, he suggestedthat there would be a set of laws that would determine theevolution of the universe
