According to one report, she has shown that a group mind is capable of changing the basic physical property of leaves, making plants grow twice as high as normal, altering the molecular cluster of water, raising the pH level of polluted water, lowering violence in war-torn or crime-ridden areas and improving the health of patients with diagnosed conditions.
RNNT instead derives the critical cluster size from dissociation and condensation rates at the surface of a molecular cluster. A brief derivation of a nucleation rate equation based on this framework is given in the preface.
