The most prolific
crystal on our planet Earth is the quartz.
Quartz emits
electricity when pressure is applied to it at certain angles. This
current is too small for humans to detect, but properly amplified,
the current is very exact and reliable. This effect is named
piezoelectricity after the Greek word, meaning "to press".
Taking it further,
when electricity is fed to a quartz, it oscillates at a
frequency depending on the intensity of the current and thickness
and of the quartz and this became the cheapest and most reliable
transmitter of radio frequency waves.
Till today, the
frequency of radio stations with 50,000 watts or more of power is
controlled by a tiny quartz chip not longer than a thumbnail.
From then on the uses
of quartz crystals went from telling time to conductors of
lightning.
Now, a new age
emerges based on transmitters, semi conductors and integrated
circuits using silicon and germanium crystals albeit man made copies
of natures bounty.
Laser technology
which employs various types of crystals, working in the same way as
quartz oscillons, are now used to amplify electromagnetic radiation
passed through them.
They can produce
fusion energy hotter than the interior of the Sun and are used at checkout counters, connect alignment of buildings and structures
with accuracy far beyond any other means.
