Title: Is classical mechanics based on Newton's laws or Eulers analytical equations?
Authors: H.Iro (Institute for Theoretical Physics, Johannes Kepler University, Linz, Austria)

In an example I illustrate how my picture of physics is enriched due to my frequent conversations with Reinhard Folk. The subject is: Who wrote down the basic equations of motion of classical mechanics for the first time? (To be sure, it was not Newton.)

Key words: history of science, classical mechanics
