Information can be conceived as being composed of two complementary components: novelty and confirmation. Whenever either of the two is zero, information is zero. Genetic information, too, requires both novelty and confirmation. Evolution can be seen as the history of diversification. Selection alone reduces diversity. Recessivity appears to serve as a mechanism to protect diversity against selection. So does the geographical and behavioral 'separation' of species. Both recessivity and separation can be seen as 'error-friendly', a broader concept that is supportive (...) of diversity, learning and further evolution. This concept should also be obeyed in technological applications. (shrink)

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. Several interpretations of the process as given in the liteature are discussed.4. Realistic Interpretation. Discussion of the de Broglie-Bohm-Bell interpretation. If well formulated, it is not a necessary consequence of quantum theory but cannot be excluded.

Scientists cannot take a neutral position regarding the way progress evolves. The environment, social justice and international order are the key factors for constructing peace.
