Thermodynamics

Thermodynamics States About Energy Conversion Thermodynamics is the branch of science that embodies the principles of energy transformation in macroscopic systems. The general restrictions which experience has shown to apply to all such transformations are known as the laws of thermodynamics. These laws are primitive; they cannot be derived from anything more basic. The first law of thermodynamics states that energy is conserved; that, although it can be altered in form and transferred from one place to another, the total quantity remains constant. Thus, the first law of thermodynamics depends on the concept of energy; but, conversely, energy is an essential thermodynamic function because it allows the first law to be formulated. This coupling is characteristic of the primitive concepts of thermodynamics. The words system and surroundings are similarly coupled. A system is taken to be any object, any quantity of matter, any region, and so on, selected for study and set apart (men...

Quantum Physics Theory

Quantum Chromodynamics
In physics, quantum chromodinamics (QCD) is a theory that explains the strong nuclear force in terms of force carriers called Gluons, acting between subatomic particles called Quarks. Protons, neutrons, and other particles of the Hadron class are composed of quarks. In theory, there are six types, or “flavors,” of quarks, further characterized by three indistinguishable quantities referred to as “colors.” Color changes and quark grouping are manifestations of the strong nuclear force.

Quantum Electrodynamics
In Physics, quantum electrodynamics (QED) in the theory that explains the electromagnetic force of electrons and other charged particles in terms of force carriers called photons. QED was developed in the 1920s and 1930s, based upon principles of electromagnetism, relativity and quantum mechanics.

Quantum Mechanics
Quantum mechanics is the fundamental theory used by 20th century physicists to describe atomic and subatomic phenomena. It has proven very successful in tying together a wide range of observations into a coherent picture of the universe.
