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 [2] from 3 Hz through 60 Hz [3] and appear as distinct peaks at extremely low frequencies around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz.
The fundamental Schumann resonance is at approximately 7.83 Hz, the frequency at which the wavelength equals the circumference of the Earth, and higher harmonics occur at 14.1, 20.3, 26.4, and 32.4 Hz, etc. Lightning strikes excite these resonances, causing the Earth–ionosphere cavity to "ring" like a bell, resulting in a peak in the noise ...
Winfried Otto Schumann (May 20, 1888 – September 22, 1974) was a German physicist and electrical engineer who predicted the Schumann resonances, a series of low-frequency resonances caused by lightning discharges in the atmosphere.

The explosion occurred at a I. Schumann & Co. copper alloy plant, and caused a large fire and catastrophic damage to the facility and damaged multiple cars in a lot across the street. The explosion was heard by civilians outside of the plant, and by 3:00pm, fire crews from multiple cities were then sent to 22500 block on Alexander Road where ...
Past continuity announcers such as Nicoletta Orsomando or Rosanna Vaudetti are regarded today as cultural icons of the 1960s, particularly because of their impeccable elegance and perfect pronunciation of Italian. From 2003 until 2016, all in-vision links on Rai 1, Rai 2 and Rai 3 had been pre-recorded by a smaller team of station announcers.
"The average fundamental mode of resonance is around 7.8 Hz, and the rest of modes are 14, 20, 26, 33, 39, and 45 Hz with slight diurnal variation." However, the wiki article's /*Description*/ currently says they "appear as distinct peaks at extremely low frequencies around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz" yet cites that ...
Below is an episode list for both the British TV series Saturday Live and Friday Night Live which were essentially the same production. The series originally aired on Channel 4 between 1985 and 1988, but it briefly returned in 1996, and there have also been a number of one-off special shows. [1]
