1. References to St. Elmo's fire can be found in the works of
,), Pliny the Elder (Naturalis Historia,
book 2, par. 101), and Antonio Pigafetta's journal of his voyage with
Ferdinand Magellan. St. Elmo's fire, also known as "corposants" or
"corpusants" from the Portuguese corpo santo ("holy body"), was a
phenomenon described in The Lusiads.
Nikola Tesla created St. Elmo's Fire in 1899 while testing his latest
invention known as the Tesla coil .
St. Elmo's fire was seen around the coil and was said to have lit up the
wings of butterflies with blue halos as they flew around.
Shortly before the crash of the Luftschiffbau Zeppelin's Hindenburg in
1937, Professor Mark Heald of Princeton saw St. Elmo's Fire flickering
along the airship's back a good minute before the fire broke out.
Standing outside the main gate to the Naval Air Station, he watched,
together with his wife and son, as the airship approached the mast and
dropped her bow lines. A minute thereafter, by Mr. Heald's estimation, he
first noticed a dim "blue flame" flickering along the backbone girder
about one-quarter the length abaft the bow to the tail. There was time
for him to remark to his wife, "Oh, heavens, the thing is afire," for her to
reply, "Where?" and for him to answer, "Up along the top ridge" – before
there was a big burst of flaming hydrogen from a point he estimated to
be about one-third the ship's length from the stern.

2. This global electromagnetic resonance phenomenon is named after physicist Winfried Otto
Schumann who predicted it mathematically in 1952. Schumann resonances occur because the
space between the surface of the Earth and the conductive ionosphere acts as a closed
waveguide. The limited dimensions of the Earth cause this waveguide to act as a cavity
for electromagnetic waves in the ELF band. The cavity is naturally excited by electric currents in
lightning. Schumann resonances are the principal background in the electromagnetic spectrum
beginning at 3 Hz and extend to 60 Hz, and appear as distinct peaks at extremely low
frequencies (ELF) around 7.83 (fundamental), 14.3, 20.8, 27.3 and 33.8 Hz.
In the normal mode descriptions of Schumann resonances, the fundamental mode is a standing
wave in the Earth–ionosphere cavity with a wavelength equal to the circumference of the
Earth. This lowest-frequency (and highest-intensity) mode of the Schumann resonance occurs
at a frequency of approximately 7.83 Hz, but this frequency can vary slightly from a variety of
factors, such as solar-induced perturbations to the ionosphere, which comprises the upper wall
of the closed cavity. The higher resonance modes are spaced at approximately 6.5 Hz
intervals, a characteristic attributed to the atmosphere's spherical geometry. The peaks exhibit
a spectral width of approximately 20% because of the damping of the respective modes in the
dissipative cavity. The 8th partial lies at approximately 60 Hz. Observations of Schumann
resonances have been used to track global lightning activity. Owing to the connection between
lightning activity and the Earth's climate it has been suggested that they may also be used to
monitor global temperature variations and variations of water vapor in the upper troposphere.
It has been speculated that extraterrestrial lightning (on other planets) may also be detected
and studied by means of their Schumann resonance signatures. Schumann resonances have
been used to study the lower ionosphere on Earth and it has been suggested as one way to
explore the lower ionosphere on celestial bodies. Effects on Schumann resonances have been
reported following geomagnetic and ionosphere disturbances. More recently, discrete
Schumann resonance excitations have been linked to transient luminous events – sprites, elves,
jets, and other upper-atmospheric lightning. A new field of interest using Schumann resonances
is related to short-term earthquake prediction.
