An abstract of a paper read before the Physical Society. The phenomena of vacuum discharges were, Prof. Thomson said, greatly simplified when their path was wholly gaseous, the complication of the...

In The Electrical Engineer of June 10 , I have noted the description of some experiments of Prof. J. J. Thomson, on the “Electric Discharge in Vacuum Tubes,” and in your issue of June 24 Prof. Elihu...

As was to be expected, the lecture delivered by Mr. Tesla in which he describes the illuminating effects observed in vacuum tubes, has called forth a number of communications from other experimenters...

In The Electrical Engineer of August 12 , I find some remarks of Prof. J. J. Thomson, which appeared originally in the London Electrician and which have a bearing upon some experiments described by me...

TO THE EDITOR OF THE ELECTRICIAN. Sir: In The Electrician for July 17th there is a description of some experiments made by Mr. Nikola Tesla, which are somewhat similar in character to those shown by...

The beautiful and suggestive experiments on the electric discharge in vacuum tubes, shown by Prof. J. J. Thomson on the occasion of the visit of the Physical Society to Cambridge, in May, have excited...

A communication made at the meeting of the Physical Society, held at Cambridge in the Cavendish Laboratory, on Saturday, May 9th, 1891. The phenomena of vacuum discharges were, he said, greatly...

As the inventor of the alternating current, the world is indebted to Mr. Tesla for the use of electricity carried long distances. He now discusses the probability that airplanes will rise to great...

In this remarkable and complete story of his discovery of the “True Wireless” and the principles upon which transmission and reception, even in the present day systems, are based, Dr. Nikola Tesla...

Since the introduction of the lightning rod over one hundred years ago by Benjamin Franklin, its adoption as a means of protection against destructive atmospheric discharges such as lightning bolts...
