An extension of classical hypersonic similitude is developed which takes into account the interaction effect of the displacement thickness of the boundary layer. A basic result of this viscous similitude is that the total drag including frictional drag obe}^s the classical similarity law for the pressure drag. Additional similarity conditions governing

ON THE PLAUSIBILITY OF HOMEOPATHIC ‘SIMILITUDE’
Bioethics, 2012ABSTRACTThe homeopathic principle of similitude is not based on the principle of vaccination but on the more general principle of inversion of effects, a widespread medical phenomenon. Based on the systemic networks which play an important role in response to stress, this principle concerns the reorganization of regulation systems, through a coherent ...
