RAYS AND RADIATION




(This article was composed in 2020.  We since have an entire museum room and display devoted to this topic...)


"I was working with a Crookes tube covered by a shield of black cardboard. A piece of barium platino-cyanide paper lay on the bench there. I had been passing a current through the tube, and I noticed a peculiar black line across the paper. ...
The effect was one which could only be produced in ordinary parlance by the passage of light. No light could come from the tube because the shield which covered it was impervious to any light known even that of the electric arc...
I did not think I investigated...I assumed that the effect must have come from the tube since its character indicated that it could come from nowhere else.  It seemed at first a new kind of invisible light. It was clearly something new, something unrecorded...  There is much to do, and I am busy, very busy."
Wilhelm Konrad Röntgen, Discoverer of the X-Ray


"In July 1893, I proposed a new treatment for small-pox, which consists in placing the patients in rooms from which the chemical rays of the solar system are excluded by interposing red glass or thick red cloth.  The result of this method of treatment is that the vesicles as a rule do not enter upon the stage of suppuration, and that the patients get well with no scars at all, or most with extremely slight scarring...this influence, which is not confined to variola, depends upon a principle which will, perhaps, find its practical application in other exanthematous and cutaneous affections...the so-called chemical rays, placed in the blue and violet, and especially the ultra-violet parts of the spectrum are the most refrangible; the chemical effect is here at the maximum, the heating effect at the minimum. "
Niels Reyn Finsen, Pioneer in Phototherapy

"The Realms Beyond The  Senses, The Reality Of The Unseen..."
Dr. Frederick Finch Strong

“ When we look at the world around us, on Nature, we are impressed with its beauty and grandeur. Each thing we perceive, though it may be vanishingly small, is in itself a world, that is, like the whole of the universe, matter and force governed by law,—a world, the contemplation of which fills us with feelings of wonder and irresistibly urges us to ceaseless thought and inquiry. But in all this vast world, of all objects our senses reveal to us, the most marvelous, the most appealing to our imagination, appears no doubt a highly developed organism, a thinking being.  If there is anything fitted to make us admire Nature’s handiwork, it is certainly this inconceivable structure, which performs its innumerable motions of obedience to external influence. To understand its workings, to get a deeper insight into this Nature’s masterpiece, has ever been for thinkers a fascinating aim, and after many centuries of arduous research men have arrived at a fair understanding of the functions of its organs and senses...”
Nikola Tesla, On Light And Other High Frequency Phenomena

RAYS

My interest in rays started in 1995 when I began experimenting with vacuums and Tesla Coils.  I noticed a peculiar yellow-green glow in some tubes that captivated my attention.  After some years, I learned that this glow was caused by X-Rays.  It is now 25 years later.  I spent my whole life studying "Rays" of different kinds, from visible light to X-Rays, Ultraviolet rays, Gamma Rays.  I had the unique privilege of studying electrical discharges that were unique to my laboratory and few others over time, outside of Kinraide and Tesla.  Now in the later part of life I am devoting my time to the ultraviolet spectrum of the farthest reaches.  I believe I am pioneering this kind of work with regard to the unique spectrums I am producing, and expect like Schumann, Lyman, Kinraide, Strong, and others  - it will probably occupy my life and work until the end.  The unknown is  a beautiful things to be immersed in... Jeff Behary, 2020.



Endless reading and experimentation are the keys to understanding obscure topics such as invisible "rays"...

Dr. Frederick Finch Strong, pioneer in Electrotherapy and phototherapy.  His book "High Frequency Currents" inspired me to start a museum.

Strong was a pioneer of high frequency coils for therapy and worked with Earle Ovington and Thomas Burton Kinraide.
Strong also invented the vacuum electrode in 1896.  The following images are of vacuum electrodes made around the world.
