This book is designed as a textbook for students who need to fulfil their science requirements. Part I explores classical physics from its beginnings with Descartes, Galileo, Kepler, and Newton, to the relativity theories of Einstein. Special emphasis is given to the development of the objective, materialist, and deterministic worldview of classical physics. The influence of Newtonian physics on other fields of science and on society is emphasized. Finally, some of the problems with the worldview of classical physics are discussed and a preview of quantum physics is given.
