The Concept of Motion in Modern Physics — •Michael Vogt — HfBK Dresden, Kunstbezogene Wissenschaften, Güntzstr. 34, 01307 Dresden

Since ancient Greece physics can be understand as the science of moving things, change of beings, or motion in general. The way, how a theory has access to its specific subject, determines the concept of reality. The physical concept of motion, therefore determines physical reality.

For the identification of the characteristic difference between classical physics and quantum physics it is necessary to establish a term of motion with extended comprehension. Analysing the Physics of Aristotle under this point of view provides us with an appropriate concept of motion. It will be shown that within the modern physics, there is initially a reduction of all types of motions to continuous locomotion. However, by introducing discontinuity in the change of state within quantum mechanics we no longer can believe, that there is continuity in all kinds of changes or motions. Therefore, the reduction to continuous locomotion is no longer possible in the quantum world.

Utilizing the Aristotelian concept of coming-to-be and perishing it is possible to develop a specific new concept of motion, which is suitable for quantum physics. Thus, the relation between classical and quantum physics can be elucidated in a novel way.
