HELP - HELP - HELP


Nikola Tesla gave 3 lectures in London, England, in the year of 1892.
Concentration of attention to the year of 1892 is most important, no
matter where he traveled during that year. 

1.) "On the dissipation of the electrical energy of the Hertz
resonator," Electrical Engineer, New York, (Dec 21st, 1892) 

2.) "Experiments with alternate currents of high potential and high
frequency" (Lecture before IEE, Feb. 1892 in London), Electrical
Engineer, London, (April 22nd, 29th, May 6th, 13th, 20th, June 3rd,
10th, 17th, 24th 1892)
