One of the most general and most universally used methods
in science is so-called perturbation technique.
Response to a well chosen perturbation can reveal object properties
that are not obvious when the perturbation is absent.
For example, if you need to know if a wall next to you is
solid or hollow, all you need to do is to "knock"
it gently and listen to its response. The response of the
wall (the sound it emits) reveals the wall's internal properties.
Similar approach is used to investigate properties of extremely
wide range of objects in all imaginable scientific disciplines:
from physical, biological, Real World objects and systems
to objects of purely hypothetical and imaginary nature such
as mathematical models.
Kirlian Effect is a visible electro-photonic glow of an object
(see the picture on the right) in response to pulsed electrical
The magnitude of the excitation is adjusted to induce the
avalanche effect in the gas surrounding the object. The avalanche
effect amplifies the response of the object so that it can
be observed as a visible glow. The effect has been observed
by Tesla late in 19th century, but named after Semion Kirlian
who investigated it since 1930s.
Note, that there is no point exciting object in vacuum, since
the avalanche effect amplification of the object response
can only occur in ionised gas.
Much like a sound
of a disturbed wall reveals its internal properties, the visible
electro-photonic glow contains information about the object
that was excited to glow.
In early days, Kirlian images were recorded on photographic
emulsion. Since the sensitivity of a photographic emulsion
varies greatly with environmental factors such as humidity,
recordings were not reproducible. As a result, some scientists
dismissed the Kirlian effect as useless.
Modern GDV instruments
developed by Prof Korotkov use glass electrodes
and their recordings are highly reproducible in a wide range
of environmental conditions.
Using reproducible recording techniques we can focus on the
in stimulated electro-photonic images.
