Abstract
This experiment was designed to test the hypothesis put forward by P. Bourkas, A.
Delinick and C. Karragiannopoulos of the National Technical University of Athens (NTUA)
that Ultra High Succussed Dilutions (UHSD) can be distinguished from control solutions
by an Electric Measurement Device (EMD), developed by the NTUA team. A pre-formulated
experimental protocol was followed, measuring in random sequence test solutions of
double-distilled and deionised water (aqua injectabile), potentised water (6 cH, 30 cH), Natrum muriaticum (Nat mur) potentised in aqua injectabile (6 cH, 30 cH), either blind or open. The number of measurements was determined by
a power analysis based on open pilot readings. While the open pilot trial performed
by the NTUA team showed a large difference in readings for the controls and test-solutions,
the experimental blind test was negative. The only significant difference observed
was between Nat mur 6 cH and Nat mur 30 cH, and the direction of the difference was in the opposite direction from that
predicted by theory and found in the pilot experiment. No differences were found between
any other conditions, and in particular Nat mur 30 cH and aqua 30 cH could not be distinguished. It was suggested that the failure to detect a difference
in the main trial resulted from a different brand of water being used in the main
trial; the likelihood of this, and other alternative explanations, is discussed. It
was concluded that the EMD is a highly sensitive apparatus for measuring impurities
in water. As yet there is no obvious link between the measurement of impurities in
water and the purported alteration of solvent in the process of homoeopathic potentisation.
