Among his publications are the books The English Galileo: Thomas Harriot’s Work on Motion as an Example of Preclassical Mechanics (Springer 2008) and Historical Epistemology of Space: FromPrimate Cognition to Spacetime Physics (Springer 2016).Matteo Valleriani is research group leader of Department I at the Max Planck Institute for the History of Science. He investigates the relation between diffusion processes of scientific knowledge, practical, and technological knowledge as well as their economic and political preconditions. In particular, his research focuses on the Hellenistic period, the late Middle Ages and the early modern period. Among his principal research endeavors, Matteo Valleriani, leads the project “The Sphere. Knowledge System Evolution and the Shared Scientific Identity of Europe” (https://sphaera.mpiwg-berlin.mpg.de), which investigates the formation and evolution of the shared scientific identity in Europe between the 13th and the 17th centuries. Among other publications, Matteo Valleriani is author of the book Galileo Engineer (Springer Dordrecht 2010) and Editor of The Structures of Practical Knowledge (Springer Dordrecht 2017).
