Schumann Resonance
The Schumann resonances (SR) are a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere. Description The global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonances are the principal background in the part of the electromagnetic spectrum from 3 Hz through 60 Hz, and appear as distinct peaks at extremely low frequencies (ELF) around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz. Schumann resonances occur because the space between the surface of the Earth and the conductive ionosphere acts as a closed, although variable-sized waveguide. The limited dimensions of the Earth cause this waveguide to act as a resonant cavity for electromagn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Schumann (; 8 June 181029 July 1856) was a German composer, pianist, and influential music critic. He is widely regarded as one of the greatest composers of the Romantic era. Schumann left the study of law, intending to pursue a career as a virtuoso pianist. His teacher, Friedrich Wieck, a German pianist, had assured him that he could become the finest pianist in Europe, but a hand injury ended this dream. Schumann then focused his musical energies on composing. In 1840, Schumann married Friedrich Wieck's daughter Clara Schumann, Clara Wieck, after a long and acrimonious legal battle with Friedrich, who opposed the marriage. A lifelong partnership in music began, as Clara herself was an established pianist and music prodigy. Clara and Robert also maintained a close relationship with German composer Johannes Brahms. Until 1840, Schumann wrote exclusively for the piano. Later, he composed piano and orchestral works, and many Lieder (songs for voice and piano). He composed ...
