Gregor Mendel was one of the first biologists to use mathematical
analysis to prove hypotheses. He used elementary probability theory in
his word. He was also inspired by the atomic theory of matter (an
appropriate example of cross-fertilization in science). D. Vaccari et al.; Environmental Biology for Engineers and Scientists (2005)
Chemistry proved as essential an ingredient to the new science of soft
matter as ideas and techniques from physics, together with renewed
conversation between the two sciences. Chemists brought not only the
careful synthetic construction of the remarkable giant molecules and
assemblies of soft materials but also ways of thinking about and
characterizing the subtle forces between them. Arising from ancient
technology, the imaginative leaps of individuals, and the
cross-fertilization of ideas—including the final opening of a window onto the atomic world itself, imagined for so many centuries—it
is not possible to tell a convincing story of the science of soft
matter without visiting some more of its history in each case study.

Cross-fertilization occurs when new legal solutions to existing problems are proffered using rules or or principles from
other areas of international law. Erika Techera; Routledge

Therefore, a cross fertilization between terrestrial applications
and marine ones seems possible, which should result in more efficient,
flexible and reliable ships. A. Marino and V. Bucci; Technology and
Science for the Ships of the Future (2018)
