Connections between engineering and science

Abstract
A method which sheds some light on the manner in which engineers draw or do not draw upon science is described. References in innovative engineering articles will reflect the degree to which the innovation draws upon engineering or science. Furthermore an examination of the citation network surrounding the innovation should reveal the closeness or distance of the science connection. To test out this idea one of the innovations described by Langrish (1972) `The Severn Bridge design' is selected for study.
