In reading ‘electrical oscillator’, you will probably automatically think ‘earthquake machine’. This charming title aside, electrical oscillators at its core employ an amplifier whose output is fed back to the input, so the signal regenerates and sustains itself. In this 1919 publication, Tesla further expands on one of his most famous inventions.

Nikola Tesla believed the universe was never bound to spiritual or natural laws, but is in essence a machine where we are but a mere part of. In this 1915 text Tesla applies the mechanical theory of life to the greater events of the time such as the war and the earthquake in Italy. He states that the man as a machine is joined in a universal wheelwork that feeds cosmic disturbances to our world and as a result introduces calamities that are, in the great scheme of things, not at all arbitrary but interconnected.

In light of Heinrich Hertz’s experiments surrounding the Maxwellian electromagnetic theory of light, Tesla seeks to further validate his own system, which had thus far acquired little understanding. In this article, Tesla specifically focuses on some disturbances he observed in his own research and what they teach us about the behavior of energy. This article mainly expands on the effect solar radiation has on the wireless transmissions.

In this text written for The Electrical Experimenter, Tesla shows himself to be the real "Father of the Wireless". He fully discredits the Hertz theory and explains that the real Hertz waves die out even after traveling a short distance. He expands further on the reactions of this theory he felt has held strength for too long and introduces his own revolutionary alternative.

As one of history’s greatest scientists, Nicola Tesla paved the way for a great number of principles but is perhaps best remembered for his pioneering work with electricity. His contributions to the design of the modern alternating current (AC) electricity supply system are perhaps the most notable. This lecture delivered to the American Institute of Electrical Engineers in Columbia College, N.Y., on May 20, 1891, marks one of his most important public addres
