A journal of the history of science seems almost obliged to mark the transition from one millennium to another, artificial though that may be. It seems even more contrived for a journal that is about science related to The Royal Society, for our history spans not even a millennium but almost exactly one–third of that period. Yet the history of science in those years has much to teach us today about the practice and use of science and to help in promoting its understanding among the wider public. The Society and its Fellows have been particularly deeply involved in the development of a number of disciplines, and so we have essays on representative topics—time, microscopy, exploration, geology and planetary studies, together with some cautionary tales about prediction—though not the only ones that could have been included. One topic, the science of materials, is represented by a book review. As is usual for the first issue of a year, we include the President's Address to the Anniversary Meeting—his last, and the last of the millennium
