Research in Cambridge is less complete than other sections because material relating to research projects continuing after Weis-Fogh's death in 1975 was retained by the Department of Zoology, Cambridge. This period marked the growth and diversification of Weis-Fogh's research interests: he supervised two major research teams (see D.35 and D.36-D.38), as well as continuing research on insect flight on which he published a major paper in 1973 (D.48-D.53). The section ends with Weis-Fogh's plans for a project to study biological fluid dynamics in the University of Cambridge, which were never put into action.
