One of my favorite quotes :
"Randall Cole Roffe: Harmonic Resonance
The application of the principles of one science into another is often neglected. Today we have a massive and growing volume of experimentally proven information that certainly does not always find its every application. In the real world, we can work from scientific theory, through experimentation, into an engineered result, but just as often we work via reverse engineering, from the result back into the origin.
If we take a good look -- and listen -- at the whole of manifestation, and apply the principles of acoustics and music, and of the color wheel, the grand pattern that emerges is self-evident.More
than this, a possible explanation of a medium of transmission of a universal electrogravitational influence, as a plenum far more fundamental than an ether, becomes apparent. With this realization a
whole new understanding of physics also emerges, with awesome possibilities."
The God Helmet is an experimental apparatus originally called the Koren helmet after its inventor Stanley Koren. It was developed by Koren and neuroscientist Michael Persinger to study creativity, religious experience and the effects of subtle stimulation of the temporal lobes.  Reports by participants of a "sensed presence" while wearing the God helmet brought public attention and resulted in several TV documentaries.  The device has been used in Persinger's research in the field of neurotheology, the study of the neural correlations of religion and spirituality. The apparatus, placed on the head of an experimental subject, generates very weak fluctuating magnetic fields, that Persinger refers to as " complex." These fields are approximately as strong as those generated by a land line telephone handset or an ordinary hair dryer, but far weaker than that of an ordinary refrigerator magnet and approximately a million times weaker than transcranial magnetic stimulation. 
Persinger reports that many subjects have reported "mystical experiences and altered states" while wearing the God Helmet.
