Publication of Galileo's Starry Messenger in 1610, detailing startling observations with the newly invented telescope, sparked immediate furor among the astronomers and philosophers of the day. The discovery of the "Medicean stars" (the satellites of Jupiter) was pronounced a hoax, an optical illusion, a logical and theological impossibility. Stillman Drake, one of the world's foremost Galileo scholars, recreates in Telescopes, Tides, and Tactics the fascinating aftermath of the publication of the Starry Messenger. Drawing on Galileo's scientific working papers and the letters and notebooks of his colleagues, Drake presents an imaginative Galilean dialogue using the text of the Starry Messenger as a departure point for discussions of appropriate scientific method, new discoveries, and the emergence of a new world view at this early stage of the Scientific Revolution.

Drake has revised his earlier abridged translation of the Starry Messenger, and for the first time the entire work is presented here in modern English. No other edition or translation of this famous work has analyzed Galileo's recorded observations in detail, compared them with modern calculations, or explained the later use he made of them. In the accompanying fictional dialogue, Salviati, Sagredo, and Sarpi reread the Starry Messenger in 1613 and discuss events and issues raised in the three years since its publication. Much of the dialogue is based on archival materials not previously cited in English. Drake has unearthed a wealth of information that will interest the lay reader as well as the historian and the scientist—descriptions of the various and occasionally bizarre critics of Galileo, a reconstruction of Galileo's promised book on the system of the world, his tables of observations and calculations of satellite motions, and evidence for an early tide theory. It was this theory explaining tides by motions of the earth, rather than the influence of Platonic metaphysics, Drake argues that played a major role in Galileo's acceptance of Copernican astronomy.

Telescopes, Tides, and Tactics is a thorough portrait of Galileo as a working astronomer. Offering much more than a commentary on the Starry Messenger, Drake has written a novel and absorbing contribution to the history of physics and astronomy and the study of the Scientific Revolution.

The lands bordering the tidal river Thames and the Thames Estuary have historically been highly vulnerable to marine flooding. The most severe of these floods derive from North Sea storm surges, when wind and tide combine to drive huge quantities of water against the coast, as happened to devastating effect in 1953. This project seeks to understand the occurrence of storm flooding in the past, and to explore the ways in which people have responded to the threat. The project draws upon rich surviving documentary sources to study the impact of storm flooding upon the reclaimed marshlands bordering the tidal Thames and its estuary during the period c.1250-1550. Year-by-year accounts of the management of riverside properties have been examined and the degree to which reclaimed land was lost to the sea during the later Middle Ages assessed. The impact of population decline and agrarian recession upon the economics of coastal and river-side defence has been considered. The flood threat to medieval London’s low-lying suburbs has been investigated and the possibility that the long-term flooding of lands down-river spared the city the worst effects of North Sea storm surges explored. Parallels have also been sought in the modern policy of managed retreat or realignment. The volume concludes with an overview of the multi-faceted work of the Thames Discovery Programme, which is increasing our knowledge of many aspects of the Thames’s past, from medieval fish traps, through nineteenth-century shipbuilding, to the Blitz, which posed a new and very real flood threat to the mid-twentieth century metropolis.
