1. Realism. Physicists claim rightly to speak about reality. But what does “reality” mean?2. The Copenhagen Interpretation (CI). We consider CI as a minimal semantics for quantum theory, leaving ways open for additional interpretation.3. The Measuring Process.

If well formulated, it is not a necessary consequence of quantum theory but cannot be excluded.
