George Johnstone Stoney


George Johnstone Stoney FRS (15 February 1826 – 5 July 1911) was an Irish physicist. He is most famous for introducing the term electron as the "fundamental unit quantity of electricity".

He had introduced the concept, though not the word, as early as 1874, initially naming it "electrine", and the word itself came in 1891. He published around 75 scientific papers during his lifetime. https://en.wikipedia.org/wiki/George_Johnstone_Stoney


Keely
"Given that force can be exerted by an act of will, do we understand the mechanism by which this is done? And if there is a gap in our knowledge between the conscious idea of a motion and the liberation of muscular energy needed to accomplish it, how do we know that a body may not be moved without ordinary material contact by an act of will? Keely contends that all metallic substances after having been subjected to a certain order of vibration may be so moved. "Scientists are verging rapidly toward the idea that immense volumes of energy exist in all conditions of corpuscular space. I accept Prof. Stoney's idea that an apsidal motion might be caused by an interaction between high and low tenuous matter, but such conditions, even of the highest accelerated motion are too far down below the etheric realm to influence it sympathetically, even in the most remote way. The conception of the molecule disturbing the ether, by electrical discharge from its parts is not correct... the highest conditions associated with electricity come under the fourth descending order of sympathetic conditions. The conjecture as regards the motion being a series of harmonic elliptic ones, accompanied by a slow apsidal one, I believe to be correct... The combination of these motions would necessarily produce two circular motions of different amplitudes whose differing periods might correspond to two lines of the spectrum as conjectured, and lead the experimenter, perhaps, into a position corresponding to an ocular illusion. Every line of the spectrum, I think, consists not of two close lines, but of compound triple lines; though not until an instrument has been constructed, which is as perfect in its parts as is the sympathetic field that environs matter, can any truthful conclusion be arrived at from demonstration."
