RSSMechanics
Mechanics can be seen as the
prime, and even as the
original, discipline of
physics. It is a huge body
of knowledge about the
natural world. It also
constitutes a central part
of technology. ... > full story
List of phases of matter
This is a list of the
different phases of matter
including the more exotic
ones. Generally phases of
matter are distinguished by
the pressure and
temperature, transforming

Subatomic particle
A subatomic particle is a
particle smaller than an
atom: it may be elementary
or composite. Particle
physics and nuclear physics
concern themselves with the
study of these particles,
their interactions, and
... > full story
Quantum number
A quantum number describes
the energies of electrons in
atoms. Each quantum number
specifies the value of a
conserved quantity in the
dynamics of the quantum
system. Since any quantum
system can have one or more

Particle physics
Particle physics is a branch of physics that studies the elementary constituents of matter and radiation, and the interactions between them. It is also called "high energy physics", because many ... > more -
Electromagnetism
Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, which exerts a force on those particles that possess the property of electric charge, and is in turn ... > more -
Spin (physics)
In physics, spin refers to the angular momentum intrinsic to a body, as opposed to orbital angular momentum, which is generated by the motion of its center of mass about an external ... > more -
Chemical bond
A chemical bond is the physical phenomenon of chemical substances being held together by attraction of atoms to each other through sharing, as well as exchanging, of electrons -or electrostatic ... > more -
Scanning tunneling microscope
The scanning tunneling microscope or STM, was invented in 1981 by Gerd Binnig and Heinrich Rohrer of IBM's Zurich Lab in Zurich, Switzerland. t is used to obtain images of conductive surfaces at an ... > more -
Quantum tunnelling
Quantum tunnelling (or tunneling) is the quantum-mechanical effect of transitioning through a classically-forbidden energy state. Consider rolling a ball up a hill. If the ball is not given enough ... > more
