Science is full of surprises. Fortunately, most of these surprises are small. A scientist, for example, might make an unexpected discoverey, but the discovery simply adds new data in support of an old theory. Or perhaps the discovery will endanger an existing theory, but one which has only local import. In cases like these, the existing theory will be modified, or perhaps even rejected; but the research tradition which surrounds the local theory will remain, by and large, unaffected and will (...) continue on.Small surprises are welcomed within science; they are part of the daily grist. Science needs them in order to advance in an orderly fashion. (shrink)
