RE: [TCML] Question on Tesla quote...

[Anthony Etersque <etersque26@xxxxxxxx>]

Hello, again,
 
This is what I am thinking so far, after having compared these statements with others in the book. I broke the quote into sections:
 
1. “From like considerations other conclusions of interest are reached. The most probable medium filling the space is one consisting of independent carriers immersed in an insulating fluid.”
 
I am forced to conclude, as Chris said, that this is referring to the ether which Tesla believed in.
 
2. “If through this medium enormous electrostatic stresses are assumed to act, which vary rapidly in intensity, it would allow the motion of a body through it, yet it would be rigid and elastic, although the fluid itself might be devoid of these properties.”
 
This I interpret as meaning that the ether has no rigidity – it is the electrostatic stresses acting through this ether that would give it its rigidity, while at the same time allowing normal material bodies to move through it. Tesla also spoke, I believe, along these lines on pages 273-275 of the same book where, after describing an experiment he performed to demonstrate the rigidity of a luminous thread in an evacuated tube, he said:
 
“The demonstration of the fact – which still needs better experimental confirmation – that a vibrating gaseous column possesses rigidity, might greatly modify the views of thinkers. When with low frequencies and insignificant potentials indications of that property may be noted, how must a gaseous medium behave under the influence of enormous electrostatic stresses which may be active in the interstellar space, and which may alternate with inconceivable rapidity?...Then, ether might be a true fluid, devoid of rigidity, and at rest, it being merely necessary as a connecting link to enable interaction.”
 
3. “Furthermore, on the assumption that the independent carriers are of any configuration such that the fluid resistance to motion in one direction is greater than in another, a stress of that nature would cause the carriers to arrange themselves in groups, since they would turn to each other their sides of greatest electric density, in which position the fluid resistance to approach would be smaller than to receding.” 
 
This is the statement I have been trying to figure out. What I’m thinking is that this statement is more fully described in another statement Tesla made on page 272:
 
“I think, however, that in the case of an electrode immersed in a fluid insulating medium, and surrounded by independent carriers of electric charges, which can be acted upon inductively, a sufficient high frequency of the impulses would probably result in a gravitation of the gas all around the electrode. For it would be only necessary to assume that the independent bodies are irregularly shaped; they would then turn toward the electrode their side of the greatest electric density, and this would be a position in which the fluid resistance to approach would be smaller than that offered to the receding.”
 
Does anyone have any ideas now what it means? If not, does anyone know where I can find out what it means?
 
4) "If in a medium of the above characteristics a brush would be formed by a steady potential, an exchange of the carriers would go on continually, and there would be less carriers per unit of volume in the brush than in the space at some distance from the electrode, this corresponding to rarefaction."
 
I assume he means here that a steady potential would rarify this medium. What would the “exchange of the carriers” mean?
 
5) “If the potential were rapidly changing, the result would be very different; the higher the frequency of the pulses, the slower would be the exchange of the carriers; finally, the motion of translation through measurable space would cease, and, with a sufficiently high frequency and intensity of the stress, the carriers would be drawn towards the electrode, and compression would result.”
 
On the other hand, an alternating potential would compress these “independent carriers”?
 
I am sorry if I am sidetracking this mailing list. I am not trying to bring up "alternate physics," which I know is a banned topic. I simply want to understand what Tesla was saying in this lecture.
 
Regards,
 
Anthony Etersque

In illustration of this result an experiment made by Mr. Tesla may be cited....This vibration would seem to show beyond doubt that the thread possessed rigidity, at least to transversal displacements.

Though no positive evidence has been obtained, it is thought, nevertheless, that a high frequency brush or streamer, if the frequency could be pushed far enough, would be decidedly rigid. A small sphere might then be moved within it quite freely, but if thrown against it the sphere would rebound. An ordinary flame cannot possess rigidity to a marked degree because the vibration is directionless; but an electric arc, it is believed, must possess that property more or less. A luminous band excited in a bulb by repeated discharges of a Leyden jar must also possess rigidity, and if deformed and suddenly released should vibrate."

If through this medium enormous electrostatic stresses are assumed to act, which vary rapidly in intensity, it would allow the motion of a body through it, yet it would be rigid and elastic, although the fluid itself might be devoid of these properties. Furthermore, on the assumption that the independent carriers are of any configuration such that the fluid resistance to motion in one direction is greater than in another, a stress of that nature would cause the carriers to arrange themselves in groups, since they would turn to each other their sides of greatest electric density, in which position the fluid resistance to approach would be smaller than to receding.

> What does this paragraph mean? First off, when he says “the most probable medium filling the space is one consisting of independent carriers immersed in an insulating fluid,” what “space” is it that he is referring to? Does he mean empty space (i.e. a vacuum)? By “independent carriers” are we to understand individual atomic charges? But then what would the “insulating fluid” be?

The reason I want to understand this is because I would like to know how Tesla did a later experiment relating to this, at a lecture before the Commercial Club in Chicago. If anyone would like the newspaper article from 1899 describing this most interesting experiment, please email me off-list.
