Abstract: | This paper explores the contemporaneous and intergenerational relationships among various scientific endeavors and military activity. Using European historical data from 1500 to 1900 A.D., generational (or 25-yr) fluctuations were examined for nine categories of scientific discovery and invention and for two aspects of military activity. A cross-lagged correlational analysis indicated that (a) casualties (but not war duration) has a significant negative contemporaneous association with medical discoveries, (b) several scientific disciplines display positive intergenerational influences (e.g., medicine, geology, and chemistry on biology), and (c) astronomy exhibits a negative intergenerational impact on technology, medicine, biology, and geology. The findings were discussed in terms of both stimulating interdisciplinary information exchanges and inhibitory competitive recruitment. |
