At
CERN, the
European Organization for Nuclear Research,
physicists and engineers are probing the
fundamental structure of the universe.
All matter
around us is made of
elementary particles, the
building blocks of matter. These particles occur
in two basic types called quarks and leptons.
Forces and carrier particles
There are
four fundamental forces at work in the universe:
the strong force, the weak force, the
electromagnetic force, and the gravitational
force.
Three of the fundamental forces result from the
exchange of force-carrier particles, which
belong to a broader group called "bosons".
Particles of matter transfer discrete amounts of
energy by exchanging bosons with each other.
Each fundamental force has its own corresponding
boson - the strong force is carried by the "gluon", the electromagnetic force is carried by
the "photon", and the "W and Z bosons" are
responsible for the weak force. Although not yet
found, the "graviton" should be the
corresponding force-carrying particle of
gravity.
The Standard Model includes the electromagnetic,
strong and weak forces and all their carrier
particles, and explains well how these forces
act on all of the matter particles.
Is The Standard Model Of Particle Physics
Complete?
The Standard Model has served us pretty well so
far, but there are some significant holes, the
most glaring being the fact that it doesn't
account for gravity. So for decades physicists
have been trying to find physics occurring
beyond the Standard Model,
using machines such as the LHC to help them find
clues. And now they may finally have a huge
lead.
In generally,
physics has encountered numerous
problems and unanswered questions. Physicists
are trying to solve the physics problems in the
context of modern physics or to think the beyond
of the modern physics while they have not cared
classical physics. Some physicists believe that
by combining general relativity and quantum
mechanics, these problems may be resolved and
the unanswered questions will be answered.
However, in all of these efforts, the classical
physic has been ignored, while nature is unique
and all physical phenomena, from the microscopic
or the macroscopic ones are obeying the same
law. Therefore to solve the contemporary physics
problems, the basic concepts and relations of
physics should be the foundation of classical
mechanics which have to be reviewed and
analyzed. Then, we have to
combine these three
theories of classical mechanics, quantum
mechanics and relativity in order to reach to a
unique physics. Eventually, by answering the
unanswered questions, the physics problems will
be solved.
