Carothers's polymerisation theory, and Flory's enunciation of equal reactivities, were hybrids of ideas, extensions by analogy of the principles and methods of rigorous scientific disciplines into a new field, still in a state of conceptual unclarity. Their hybrid-ideas were radical innovations which contributed towards establishing polymer chemistry as a separate chemical discipline. Joseph Ben-David's theory of hybridisation can cast new light on the social and technological origins of significant innovations in twentieth-century science. Carothers and Flory's enunciations of radically novel ideas (...) were inseperable from their identification with the new role of polymer chemist.Quasi-academic or academically peripheral milieux have had a systematic, indeed historic, role in bringing about innovations in fundamental science, in isolating significant problems and fruitful analogies, and in shaping new types of academic careers. This mechanism at the periphery offsets the pressures for conformity and orthodoxy which otherwise tend to prevail in academic science at the centre. (shrink)

Divergent models applied to the chronology of Australian science leave us with two particular problems unresolved: was late-nineteenth-century science in this peripheral setting becoming more or less dependent on its British fountainhead, and what is the meaning of the reportedly narrow, utilitarian focus of ‘colonial science’? This paper argues that a complex interplay of imperial and local imperatives makes neat classification and periodization of Australia's scientific development a hazardous venture. Compounding the complexity is the nature of the relationship between science (...) and technology, a factor largely ignored in the historiography of Australian science. Contrary to common assumptions, an empirical focus on science-technology links suggests that scientific and technological dependencies were not running in parallel, but out of phase, with science as the laggard. Indeed, it appears that science in late-nineteenth-century Australia may have developed more from its interaction with technological systems than from its own internal dynamics. (shrink)
