Review of Chasing Venus by Andrea Wulf (2012, William Heinemann)
Chasing Venus tells the tale of the various attempts to measure Venus’ transits in 1761 and 1769, tracking the wider international collaboration, the perilous journeys undertaken to various parts of the globe by astronomers, and the scientific calculations undertaken. Wulf does a good job at marshalling a lot of interrelated storylines and structuring it into an easy to follow narrative, giving a clear sense of the importance of the scientific task, the science involved, the lives of the main participants, and the wider political landscape. Several astronomers risked their lives travelling to different sites and in the case of the 1769 expeditions five lost their lives, and all put up with various hardships without any guarantee of being able to observe the transit (and a number didn’t because of clouds). In addition, the expeditions provided new knowledge about the South Seas and remote parts of Russia (Captain Cook’s first Endeavour voyage was to observe the transit in Tahiti). While the book is well researched and written, the ending is a little abrupt and it would have been useful and interesting to find about a bit more about the significance of the science and expeditions, and the subsequent lives of the astronomers, even as just short potted biographies. Overall, an interesting read.
