===Speed of sound===
The [[speed of sound]] was first accurately calculated by the Reverend [[William Derham]], [[Rector (ecclesiastical)|Rector]] of Upminster, thus improving on [[Isaac Newton|Sir Isaac Newton]]'s estimates.  Derham used a telescope from the tower of the [[church of St Laurence, Upminster]] to observe the flash of a distant shotgun being fired, and then measured the time until he heard the gunshot with a half-second pendulum. Measurements were made of gunshots from a number of local landmarks, including the [[Church of St Mary Magdalene, North Ockendon]]. The distance was known by triangulation, and thus the speed that the sound had travelled could be calculated.<ref name="Tony Fox">{{cite book | title=Essex Journal | author=Fox, Tony | pages=12–16 | year=2003 | publisher=The Essex Society for Archaeology & History}}</ref>
