Quantum means "a specific amount (quantity)". Max Planck suggested in 1900 that the energy in a wave of electromagnetic radiation comes in quanta (plural). He found that multiplying a constant by the frequency gives the energy of a single photon of light.

If the magnitude of a quantity is always an integral multiple of a definite unit, then that unit is called the quantum of the electromagnetic field and the meson is considered to be the quantum of the nuclear field.
quantum, how much) An elemental unit of energy. Its energy value is hv, where h, Planck's constant, is 6.62 × 10-27 erg-second and v is the frequency of the vibrations or waves with which the energy is associated. cf photon.
Quantum is the smallest quantity of energy that can be emitted (or absorbed) in the form of electromagnetic radiation. Energy of a quantum () is equal to E = hâˆ™ where is Planck constant and is the frequency of the radiation.
Making use of quantum-mechanical superposition. If you don't know what that means, well, I can't explain it in this sentence. But it has nothing to do with the original meaning of the word 'quantum' (i.e. a discrete unit).
1. For certain physical properties such as energy or momentum, a fundamental unit such that the property appears in integer multiples of the unit. 2. An elementary particle carrying one unit of the property. For example, the photon is the quantum of the electromagnetic field, carrying an energy equal to Planck's contant times the frequency of the light and an angular momentum equal to a multiple of Planck's constant divided by 2.
An entity whose energies occur in discrete lumps--e.g., photons are the quanta of the electromagnetic field. Quanta have both wave and particle aspects, the wave aspect being the probability of detecting the particle at a certain place and time. [Illuminati Papers, 1980
Theory of physics that explains the behaviour of nature and its forces on a very small, subatomic scale. It states that physical quantities can only have discrete values (this is quantization). According to quantum mechanics photons or electrons may be considered as particles but they can also be diffracted like waves (this is referred to as wave-particle duality). This quantum theory was proposed by Max Planck in 1900. Quantum mechanics is the more formal mathematical description of his theory which was developed in the 1920's. It also incorporates the uncertainty principle, which states that you cannot measure a particle's position and velocity at the same time. The more accurately you know its position, the less accurately you know its velocity and vice versa.
In physics, a quantum (plural: quanta) is an indivisible entity of energy. For instance, a photon, being a unit of light, is a "light quantum." In combinations like "quantum mechanics", "quantum optics", etc., it distinguishes a more specialized field of study.
QUAlity Network Technology for User-oriented Multimedia. The name of the project supported by the ECâ€™s ESPRIT and Telematics committees and managed by DANTE (on behalf of NRENs) for the support of European research networking beyond TEN-34.
Refers to the value or amount of damages awarded for the claim. It is the total amount of compensation or damages the claim is worth. NO SOLICITOR can give you an indication as to Quantum until all evidence (e.g. medical reports) are compiled and received.
A Latin term, used by lawyers and judges, which means the amount of support to be paid, as opposed to the duration of that support. â€œQuantumâ€ thus usually refers to the monthly amount of spousal support.
Quantum is an Executive Information System for health care management managed by the Corporate Executive Information System Program Office. It integrates information from throughout the health care enterprise and the marketplace to give executives a perspective on indicators and trends that affect their business.
