ABSTRACT
In August 1684 Halley’s visit to Newton provoked the creative outburst that led in just two and a half years to the highest achievement of the Scientific Revolution, the Principia. The resources on which Newton could and did draw for the revolutionary transformation that he accomplished in that short period derived from all previous revolutionary transformations so far examined. I shall now recapitulate their attainments and the ways in which these had come about; in the next chapter, we find out how Newton drew many of the lines together. What, by 1684, did the big picture of modern-science-in-the-making look like?
