John Smeaton’s experiment to estimate the efficiency of waterwheels. Philosophical Transactions 51 (1759).

This post continues our examination of Simon Schaffer’s “Machine Philosophy: Demonstration Devices in Georgian Mechanics” (1994).  Last time, we looked at how Atwood’s Machine was used at Cambridge as a dramatic means of convincing mathematics students of the validity of Newton’s laws, which they were expected to use to explain various physical phenomena.  Here we examine how proponents of Isaac Newton’s mechanics tried to use the machine to make points with audiences whose perceptions of the reach and fundamentality of Newton’s laws were varied and unstable.

First, though, let’s revisit some of the themes of Schaffer’s earlier works to see how this piece fits into a larger picture.
