Quantum Physics
Quantum physics revolves around the Quantum Theory or Quantum mechanics. Quantum physics is only available at universities as high level physics. Quantum physics is usually not offered as a first degree (Bachelor's of Science) course. At major universities, there is often a big department of physics devoted to Quantum physics full of researchers and physicists who have devoted their life to the study of quantum physics, the Quantum theory, Quantum mechanics and their applications.
A window to Quantum physics: What is quantum theory?
Quantum physics is the study of quantum theory. What is quantum theory? Quantum theory is the theory that energy does not have a continuous range of values. Instead, energy are absorbed or radiated discontinuously, in multiples of packets of energy or units. These units or packets of energy are called the Quanta.
Understanding Quantum Theory
The Quantum Theory, hence Quantum physics, is the basis of Particle Physics. Quantum theory shows how atomic particles such as electrons may be seen as having wavelike properties. Quantum physics is fundamental to the explanation of the behavior of the silicon chips in computers.
Origin of Quantum physics

Quantum physics started with the work of Max Planck. Max Planck worked on radiated energy in 1900. His theories and work were later carried on by Albert Einstein on electromagnetic radiation as well as light. Another contributor to Quantum Physics was Niels Bohr who explained the spectrum of light emitted by excited hydrogen atoms. More contributions to Quantum Physics came from Erwin Schrodinger, Werner Heisenberg, and Paul Dirac. There were other who worked on Quantum physics and derived Quantum mechanics or wave mechanics.
