Abstract:


This paper presents an overview of known experimental data dealing with the mirror symmetry breaking effect in stochastic reactions (crystallization of NaClO3 from an oversaturated aqueous solution; dissolution-crystallization of the l- and d-NaClO3 crystals mixture under stirring or boiling (Viedma ripening), and similar reactions; Soai reaction of enantioselective autocatalysis and chirality amplification; spontaneous mirror symmetry breaking by molecular self-assembly of achiral molecules and similar reactions in polymerization or liquid crystal media). Stochastic effects of chiral or racemic fields and the effect of chiral memory are discussed as well. P. Curie was convinced that “without asymmetric physical impact no asymmetric chiral effect arises”. Recent experimental data that proves the implementation of this criterion is discussed. The aforesaid reactions or effects are considered in terms of a possible chiral impact of external physical inductors as it can be expected for open systems. The meso-form structure of the environment, plasma torch of meteorite impact as a mirror symmetry breaking factor, solar asymmetric irradiation, enantioselective impact of electromagnetic fields (as a combination of the Earth magnetic field and atmospheric electricity), and some other physical inductors are reviewed. The meso-form structure of the gravitational field as a chiral inductor is most consistent with the above– mentioned reactions and effects.
