This book covers the history of kinematics from the Greeks to the 20th century. It shows that the subject has its roots in geometry, mechanics and mechanical engineering and how it became in the 19th century a coherent field of research, for which Ampère coined the name kinematics. The story starts with the important Greek tradition of solving construction problems by means of kinematically defined curves and the use of kinematical models in Greek astronomy. As a result in 17th century mathematics motion played a crucial role as well, and the book pays ample attention to it. It is also discussed how the concept of instantaneous velocity, unknown to the Greeks, etc was introduced in the late Middle Ages and how in the 18th century, when classical mechanics was formed, kinematical theorems concerning the distribution of velocity in a solid body moving in space were proved. The book shows that in the 19th century, against the background of the industrial revolution, the theory of machines and thus the kinematics of mechanisms received a great deal of attention. In the final analysis, this led to the birth of the discipline.

How did early modern philosophy of space shape the modern concept of political universalism? In this book, Pablo Bustinduy persuasively argues that political universalism emerged from both the developments of Newtonian science and the formulation of the modern philosophy of the State. In the metaphysics of an open, empty, abstract and absolute space, Bustinduy suggests, the universalist project of modern politics found its logical model and foundation. There, the anxiety of a dislocated world was overcome, and the ontology of modern physics found a specific political expression that, despite being besieged by multiple crises, still animates our political imagination. By offering a political reading of early modern philosophy of space, Space and Political Universalism in Early Modern Physics and Philosophy reveals the connections between the logical development of early modern science, the contemporary elaborations of the philosophy of the State, and the historical articulations of the Westphalian system, early capitalist social formations, and the European colonial project. In doing so, it offers a powerful reflection on how we might detach democracy from the 'perilous metaphysics' of infinite space that has engendered political violence and domination, positing space as an emptiness that prevents the closure of the political itself.

Science at the Crossroads was published by Herbert Dingle in 1972 at the end of a gruelling controversy with the English scientific world about the clock paradox in Einstein’s special relativity. It is still a seminal text, which allows us to understand and evaluate, with Cartesian clarity, the problem of that paradox for all those readers who find themselves in a widespread condition of having studied Einstein’s special relativity or received a teaching of it, and yet of not feeling comfortable it because the attempt to understand the logical connection of the parts with the whole did not succeed. Many have experienced this state of mind, and can admit it. In this way Science at the Crossroads is an important source of knowledge about Einstein’s special relativity and its historical background. Science at the Crossroads contains a great wealth of philosophical and epistemological ideas. The essay has a classic imprint, rich with sharp and clear distinctions, and very elegant in style. We meet countless research possibilities concerning the mathematical idealism of anti-classical physics after 1920 (assuming it is still correct to call it physics rather than metaphysics, as Dingle would suggest, as a partisan of modern science empirical method). Every page written by Dingle suggests research that could be carried out in depth, starting from what Dingle observes on the origins of mathematical idealism in Maxwell himself and his displacement current postulated to ensure the continuity of a given mathematical function, to end with the extreme tendencies of this kind of thought that were manifested towards the 1970s, as for example in the case of Professor Hoyle mentioned in the last chapter, who “has plainly stated his advocacy of the process of telling nature what to do instead of looking to see what she does”. Naturally, it is our task to continue Dingle’s research up to the present. The present electronic edition provides a Foreword from the editor, which informs about the basic knowledge readers are expected to have in order to fully understand Science at the Crossroads.

Novel conceptual analysis, fresh historical perspectives, and concrete physical examples illuminate one of the most thought-provoking topics in physics.
