Helge Kragh is one of our best historians of physics, and the author of several outstanding books. The idea of a history of highly speculative theories in physics is excellent. Although there are popular accounts of recent cosmological and grand-unifying theories, no historian has so far attempted to bring together old and new cases of such theories. The result makes fascinating reading and induces thought-provoking comparisons. (Olivier Darrigol, CNRS: Sphere/Rehseis
