Chamizo1 Ó Springer Science+Business Media Dordrecht 2017 Abstract A new chronology is introduced to address the history of chemistry, with edu- cational purposes, particularly for the end of the twentieth century and here identified as the fifth chemical revolution. Each revolution are considered in terms of the Kuhnian notion of ‘exemplar,’ rather than ‘paradigm.’ This approach enables the incorporation of instruments, as well as concepts and the rise of new subdisciplines into the revolutionary process and provides a more adequate representation of such periods of development and consolidation. The fifth revolution developed from 1973 to 1999 and is characterized by a deep transformation in the very heart of chemistry. That is to say, the size and type of objects (substances), the way in which they must be done and the time in which they are transformed. In one way or another, chemistry’ limits had been set out. Keywords History of chemistry Á Chemical revolutions Á Chemistry education Á Exemplars Á Instruments and subdisciplines Introduction In spite of the impressive growth and qualitative change of science over the last half century, however, historians of science still largely turn their attention to earlier periods. Thus a paradoxical temporal imbalance is created: one the one hand, the great majority of historians of science are still working on the small percentage of scientific activity A preliminary version of this paper was presented at the ISPC London 2014. & Jose´ A.
