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.
Holidays proclaimed in this way may be considered a U.S. "national observance", but it would be improper to refer to them as "federal holidays". Many of these observances designated by Congress are authorized under permanent law under Title 36, U.S. Code, in which cases the President is under obligation to issue an annual proclamation.

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.
Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.
In 2003, a New York Times article concluded "All things considered at this point, the stock market seems a more reliable gauge of the national—if not the global—emotional resonance." [19] In 2007, The Age reported that "[Nelson] concedes the data, so far, is not solid enough for global consciousness to be said to exist at all. It is not ...
"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 ...
