Quantum mechanics (QM; also known
as quantum physics, quantum theory,
the wave mechanical model, or matrix
mechanics), including quantum field
theory, is a fundamental theory in
physics which describes
nature at the smallest scales
of atoms and subatomic
particles

Do electrons orbit the nucleus?
The electrons do not orbit the
nucleus in the manner of a
planet orbiting the sun, but
instead exist as standing waves.
Thus the lowest possible energy
an electron can take is similar to
the fundamental frequency of a
wave on a string.

Important applications
of quantum theory
include quantum chemistry, quantum op
tics, quantum computing,
superconducting magnets, light-
emitting diodes, and the laser, the
transistor and semiconductors such as
the microprocessor, medical and
research imaging such as magnetic
resonance imaging and electron
microscopy.

There are a total of
four quantum numbers: the
principal quantum
number (n), the orbital
angular momentum quantum
number (l), the
magnetic quantum
number (ml), and the electron
spin quantum number (ms).

Quantum realm. The quantum
realm (or quantum parameter ) in
physics is the scale where
quantum mechanical effects
become important when studied
as an isolated system. Typically,
this means distances of 100
nanometers (10−9 meters) or less
or at very low temperature.

Do particles pop in and out of
existence?
And since energy and matter are the
same (thank Einstein for teaching us
that E=mc2 thing), matter can also
appear and disappear. ... At the
quantum level, matter and
antimatter particles are
constantly popping into existence and p
opping back out, with an electron-
positron pair here and a top quark-
antiquark pair there.

What is quantum number n?
The principal quantum number
n represents the relative overall
energy of each orbital. The
energy level of each orbital
increases as its distance from the
nucleus increases. The sets of
orbitals with the same n value are
often referred to as an electron
shell.

Reality. Reality is the sum or
aggregate of all that is real or
existent, as opposed to that which
is only imaginary. The term is also
used to refer to the ontological
status of things, indicating
their existence. In physical
terms, reality is the totality of the
universe, known and unknown.

Physicists Disagree Over Meaning
of Quantum Mechanics, Poll
Shows. The bizarre rules of
quantum mechanics may in fact
enable many of life's fundamental
processes, scientists say.
"Anyone who claims to
understand quantum theory is
either lying or crazy," physicist
Richard Feynman once said,
according to legend.
