Crystals meanings and uses
 

A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency.[1][2][3] This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators,[1] but other piezoelectric materials including polycrystalline ceramics are used in similar circuits.


Crystal healing is a pseudoscientific[1] alternative medicine technique that employs stones and crystals. Adherents of the technique claim that these have healing powers, although there is no scientific basis for this claim.

One method is where the practitioner places crystals on different parts of the body, often corresponding to so-called "chakras"; or else the practitioner places crystals around the body in an attempt to construct an "energy grid", which is purported to surround the client with healing energy.[2] Despite this, scientific investigations have not validated claims that chakras or energy grids actually exist, nor is there any evidence that crystal healing has any greater effect upon the body than any other placebo.
