Part of Psionics is the art of Radionics which was discovered, or invented, by Dr. Albert Abrams in the early part of the last century. One day in 1910 he was in his office with a patient, percussing him which does not mean he was swearing at the man but rather tapping his tummy to see how his innards sounded. It's a doctor thing. Anyway, Doc Abrams got a kind of strange noise when the man faced one way but a normal noise when he faced another. So the good doctor spent the afternoon marching the man around the office, tapping his tummy while the waiting room outside was filled with fuming other patients waiting to get their tummies tapped.
 
Our Founder, Doc Abrams.
 
The upshot of all this was that the good doctor decided that the magnetic field of the earth had something to do with the differing tummy noises and so he set up a series of experiments to find out if different phyisical and disease states would cause different tummy sounds. He procured an assistant and a length of wire, a handle and two aluminum discs. One disc was fastened to the forehead of the assistant by a rubber band and wired to the other disc on the handle. While a second assistant held the handled disc over tissue samples with various diseases, Doc Abrams tapped the tummy of the first to see where on the tummy the different sounds were coming from. This yielded all kinds of useful albeit rather strange information until one day disaster struck! The same sound came from the same place on the tummy from two different diseases!
 
Fortunately for the world, Doc Abrams was a scientific fellow and thus had in his laboratory a death ray -- er --sorry about that, a three dial resistance box which all good scientific people had laying around in those days. They never used them but it was important to look the part. Well, the good doctor took a page from Alexander the Great and cut the Gordian Knot, well actually he cut the wire, and fastened it to the connectors of the box and then fiddled with the dials while tapping the assistant's tummy. And yea, lo and verily there were different sounds again at different dial settings. The world was saved!!!
 
It all began with this little box thing.
 
And he was off and running! For the next fourteen years until he up and died, Doc Abrams designed a plethora of instruments, all for healing unfortunately, to use what he called his Electronic Relations of Abrams (he assumed that what he was doing was somehow electrical). Of course there was one little problem--finding assistants willing to stand all day and have their tummies tapped. Abrams solved that by inventing the Reflexophone which looked like a bongo drum on its side and sort of acted like a portable tummy. That became the precursor to the stick pad.
 
Now the reason I just bored you with all that is because it's a good fun story and I love to tell it. Modern Psionics has actually rather little to do with Abrams because we don't think of it as purely electro-magnetic and we aren't that interested in healing, well, at least I'm not.
