uncertainty principle
uncertainty principle (ùn-sûr´tn-tê
prîn´se-pel) noun
A principle in quantum mechanics
holding that increasing the accuracy of measurement of one observable quantity
increases the uncertainty with which other quantities may be known.
Uncertainty Principle
Uncertainty Principle, in
quantum
mechanics, theory stating that it is impossible to specify simultaneously
the position and momentum of a particle, such as an electron, with precision.
Also called the indeterminacy principle, the theory further states that
a more accurate determination of one quantity will result in a less precise
measurement of the other, and that the product of both uncertainties is
never less than Planck's Constant, named after the German physicist
Max
Planck. Of very small magnitude, the uncertainty results from the fundamental
nature of the particles being observed. In quantum mechanics, probability
calculations therefore replace the exact calculations of classical mechanics.
Formulated in 1927 by the
German physicist Werner Heisenberg, the uncertainty principle was of great
significance in the development of quantum mechanics. Its philosophic implications
of indeterminacy created a strong trend of mysticism among scientists who
interpreted the concept as a violation of the fundamental law of cause
and effect. Other scientists, including
Albert
Einstein, believed that the uncertainty involved in observation in
no way contradicted the existence of laws governing the behavior of the
particles or the ability of scientists to discover these laws.

The uncertainty principle can also
be derived from the fact that when taking a measurement of matter or it's
particles, the tools to do so can change the particles. For example, a tool
that measure's an atom's speed must change its location. Similarly, a
tool to measure an atom's direction will be affecting its speed. Heisenberg
proved a mathematical equation in which the measurement of the speed of an atom
is the reciprocal (in an equation [N*Y=Z] : N and Y are called reciprocals)
of the measurement of the location. In related uncertainty, when a person views
the
light
emitted off an object, the person is seeing how the object was one ten-millionth
of a second (or so) ago, because light needs that
time
to travel to the eye and be recognized by the brain. Therefore, one cannot observe
an atom how it exists at the same millisecond as it is viewed. In attempt to
measure the atom in a different method, one could reflect light off an atom.
However, there is another problem, in that the photon can change the velocity
(speed and direction) of that atom. This creates the problem that viewing the
atom changes its attributes. Using other atoms to measure will similarly affect
the one atom's attributes as well.
