  The qualitatively new concept of dynamic complexity in quantum mechanics is
based on a new paradigm appearing within a nonperturbational analysis of the
Schroedinger equation for a generic Hamiltonian system. The unreduced analysis
explicitly provides the complete, consistent solution as a set of many
incompatible components ('realisations') which should permanently and
probabilistically replace one another, since each of them is 'complete' in the
ordinary sense. This discovery leads to the universally applicable concept of
dynamic complexity and self-consistent, realistic resolution of the stagnating
problems of quantum chaos, quantum measurement, indeterminacy and wave
reduction. The peculiar, 'mysterious' character of quantum behaviour itself is
seen now as a result of a dynamically complex, intrinsically multivalued
behaviour of interacting fields at the corresponding lowest levels of the (now
completely causal) structure of reality. Incorporating the results of the
canonical theories as an over-simplified limiting case, this new approach
urgently needs support, since its causality and completeness are directly
extendible to arbitrary cases of complex behaviour of real systems, in sharp
contrast to the dominating inefficient empiricism of 'computer experimentation'
with primitive mechanistic (i. e. dynamically single-valued) 'models' of the
irreducibly multivalued reality.
