When I got my first Qi Simulators (infrasonic therapy units) I noticed that some worked and some didn’t. One of the key ingredients was randomness in the signal. This launched me on many years of research into the different forms of randomness that can enhance effectiveness. The result was the first Chaos Therapy device. Infrasonic Therapy with a high degree of randomness. Why is randomness so important?
