Galileo Galilei (1564-1642) was an Italian physicist, mathematician, philosopher, and astronomer. Albert Van Helden is professor emeritus of history at Rice University and the University of Utrecht. He is translator and coeditor of On Sunspots, also available from the University of Chicago Press, and coeditor of The Origins of the Telescope.
"""Van Helden's new edition remains the best available for a student readership and as good a starting point as any to this revolutionary, scintillating book.""-- ""Metascience"" ""A second edition of this widely used translation with a new preface summarizing Galileo scholarship since 1989, an expanded bibliography, and very slight revisions and corrections in the translation as well as in the introductory and concluding essays.""-- ""Journal for the History of Astronomy"""
