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.
All 66 achieved that rank while on active duty in the U.S. Air Force. Lieutenant generals entered the Air Force via several paths: 29 were commissioned via the U.S. Air Force Academy (USAFA), 22 via Air Force Reserve Officer Training Corps (AFROTC) at a civilian university, eight via Air Force Officer Training School (OTS), three via direct ...
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 ...
