Prof. Dr. Peter Mittelstaedt is emeritus professor at the University of Cologne. His main research fields are Foundations of Quantum Theory, Relativity Theory, Philosophy of Science and Logic. He has published various books with Springer: "Laws of Nature" (2005, together with P.A. Weingartner), "The Quantum Theory of Measurement" (1996, together with P. Busch and P.J. Lahti) and "Quantum Logic" (1978).Dr. Kristina Engelhard edited this 2nd enlarged edition of the book by Prof. P. Mittelstaedt. She obtained her PhD in Philosophy at the University of Cologne with a thesis entitled "The Simple and Matter. Inquiries into Kant’s Antinomy of Division" and she is currently Research and Teaching Assistant at the Philosophy Department of the University of Cologne (Germany).
