It appears, moreover, that the citation pattern of a science transcends national and cultural boundaries. At any rate. American. EUropean, and Soviet journals of physics have been found to exhibit almost identical age distribu" tions of citations (Dedijer. 1964. p. 461).

One Ifmiled aspect of the cognitive structure of the various sciences. then. is the extent of their codification. We want now to explore possible relations between codification and age·patterned behavior and processes in the sci. ences. along the following lines:

Or the similar observation by John Maynard Keynes about the brilliant young logician and mathematician, Frank Ramsey, robbed of his fulure at the age of 27. We suggest. moreover, that the statistical bias in apparent age· specific productivity differs among the variously codified sciences. In doing so. we de­ pari a bit from the allcient adage that the good die young, We propose a less crisp but more germane version: ('om IUlI'nUIII'i!l::" more good mathematicians and phYSicists than good historians and sociologists die young.
