Contents
An account, by Hertzs assistant at Bonn, which contains interesting material on Hertzs early life. The quotations from Hertzs letters provide revealing insights into Hertzs character and outlook.
This eloquent tribute to Helmholtz, prepared for the celebration of Helmholtzs seventieth birthday in 1891, reveals Hertzs lifelong gratitude and devotion to his mentor, colleague, and friend.
An important theoretical paper in which Hertz derives Maxwells equations by a novel, ingenious procedure. This leads him to assert the superiority of Maxwells theory over all competing theories of electromagnetism.
FitzGeralds review provides a good summary of Hertzs more important early papers and, despite some probing criticism, reveals his admiration for Hertzs research accomplishments and those of his mentor, Helmholtz.
An Introductory Overview that summarizes both the experimental and theoretical components of Hertzs electromagnetic research at Karlsruhe. He concludes that his experiments have confirmed the fundamental tenets of the Faraday-Maxwell theory.
A description of the techniques Hertz employed to produce and detect electromagnetic waves with wavelengths of about six meters. Resonance effects turned out to be of great importance and were used in his subsequent experiments on electromagnetism.
The first paper ever published on the photoelectric effect. In it Hertz shows conclusively that ultraviolet light increases the electric discharge from ordinary metals. In an amazingly thorough series of experiments he then discusses the effect on the discharge of changing the metals, the light sources, and the intervening medium.
Hertz describes his success in producing standing electromagnetic waves and in measuring their wavelengths. He suggests that such waves may be identical with light waves and considers that his observations provide further evidence for Maxwells theory.
This is the most impressive of all Hertzs experimental papers on electromagnetism. He demonstrates conclusively that electromagnetic waves of 66-cm wavelength can be formed into a beam by a parabolic cylindrical reflector and can be reflected, refracted, polarized, and made to interfere. Electromagnetic waves may therefore be properly called beams of light of very great wavelength.
