John Waller 
Leaps in the Dark 
The making of scientific reputations

In Leaps in the Dark, John Waller presents another collection of revelations from the world of science. He considers experiments in which the scientists’ awareness was not perhaps as keen as they might have claimed in retrospect; he investigates the jealousy and opposition that scientific ideas can provoke; he celebrates the scientists who were wrong, but for very good reasons; and he demonstrates how national interest can affect scientists and their theories. The result is an entertaining and highly readable re-examination of scientific discoveries and reputations from the Renaissance to the twentieth century. The tales in Leaps in the Dark range across a wide historical field, from a seventeenth-century witch-finder, Joseph Glanvill, to Sir Robert Watson-Watt, the self-proclaimed ‘Father of radar’. Each story underscores the rich, fascinating complexity of scientific discovery. Writing in a clear and engaging style, and skilfully weaving history in with the science, John Waller brings these scientists to life, illustrating how their work and their discoveries influenced their careers and the wider world around them.
