The principles of present-day radionics were laid down by the American doctor,
Dr Albert Abrams (1863-1924). In the context of his work into differentiation
between various symptoms by means of an automatic reflex movement of the stomach
of a patient detected by percussion. He discovered an empirically defined
arrangement of variable resistances (potentiometer). In this context, the patient
was connected via a forehead electrode to the “input” of a variable resistance box.
At the “output”, a healthy person was connected, also via a forehead electrode
(Test person). On the abdomen of the test person, it was now possible to diagnose
the pathology of the patient on the basis of settings of the decade resistance by
means of the special knock reflex.
It was not until later that Abrams found that it was not even necessary for the
patient himself to be present. It was adequate for him to be replaced by a blood
sample (as a “specimen” or “proof”). This specimen was poured into a metal cup
which (in place of the patient) was connected to the “Input” of the variable resistance box.
