Pliny said of history: “Quanta potestas, quanta dignitas, quanta majestes, quantum denique numen sit historiae.” The word quantum is the singular neuter of the Latin adjective question, meaning “how much”. “Quanta”, the neutral plural, short for “quanta of electricity” (electrons), was used in 1902 in a paper on the photoelectric effect by Philipp Lenard, who attributed Hermann von Helmholtz to the use of the word in the field of electricity. However, the word quantum in general was known before 1900,[2] for example quantum was used in E.A. Poe`s breath loss. It was often used by doctors, as in the term quantum satis. Helmholtz and Julius von Mayer were both physicians and physicists. Helmholtz used quanta in relation to heat in his paper[3] on Mayer`s work, and the word quantum is found in Mayer`s formulation of the first law of thermodynamics in his letter[4] of July 24, 1841. It gave me immense satisfaction in constructing an interpretation of these worlds because I didn`t know what quanta were. In physics, a quantum (plural quanta) is the minimum set of a physical entity (physical property) involved in an interaction. The basic idea that a physical property can be “quantified” is called the “quantization hypothesis.” [1] This means that the amplitude of the physical property can only assume discrete values consisting of integer multiples of a quanta. In physics, discrete beams in which radiation and other forms of energy occur. For example, in the Bohr atom, light is emitted in quanta called photons. (See quantum mechanics.) Hunc igitur laborem nostrum ut tam Gratis animis accipiatis, quanta sedulitate a nobis est obitus, ex aequo omnes rogatos volo.

Earum, si placet, causarum quanta quamque sit iusta una quaeque videamus. For example: The quantum of charge is the charge of an electron. The electrical charge can only increase or decrease by discrete energy levels. So there is no half load. A photon is a unique quantum of light. Light and other electromagnetic energies are absorbed or emitted in quanta or packets. The word quantum is often misused as an adjective to mean the opposite of its definition or in an inappropriate context. For example, the term “quantum mysticism” implies a correlation between quantum mechanics and parapsychology that has not been supported by empirical data. The “quantum leap” phase is used to propose a big change, while the definition of quantum is that change is the minimum possible. Neque enim tanta πολυθεοτης Gentium, quanta fuit Deorum πολυωνυμια. Einstein, on the other hand, insisted that light quanta travel alone through space, behaving like particles later called photons. In 1901, Max Planck used quanta to refer to “quanta of matter and electricity”[5], gas and heat.

[6] In 1905, in response to the work of Planck and the experimental work of Lenard (who explained his results by the term quanta of electricity), Albert Einstein proposed that radiation exists in spatially localized packets, which he called “quanta of light”. [7] Quanta, in physics discrete natural unit or packet of energy, charge, angular momentum or other physical properties. Light, for example, which appears in some respects as a continuous electromagnetic wave, is emitted and absorbed at the submicroscopic level in discrete or quantum quantities; And for light of a certain wavelength, the magnitude of all emitted or absorbed quanta is the same in energy and momentum. These particle-like packets of light are called photons, a term also applicable to quanta other forms of electromagnetic energy such as X-rays and gamma rays. Submicroscopic mechanical oscillations in the atomic layers that make up crystals also give up energy and momentum in quanta, or absorb energy and momentum called phonons. In physics and chemistry, a quantum is a discrete packet of energy or matter. The term quantum also refers to the minimum value of a physical property involved in an interaction. The plural of quanta is quanta. Seine Gracchi consiliis quanta poterant contentione obsistebant omnes boni, in quibus maxime Piso, vir consularis.

Although quantization was first discovered in electromagnetic radiation, it describes a fundamental aspect of energy that is not limited to photons. [11] In an attempt to reconcile theory with experiment, Max Planck postulated that electromagnetic energy is absorbed or emitted in discrete packets or quanta. [12] All phenomena in submicroscopic systems (the field of quantum mechanics) have a quantization: observable quantities are limited to a natural set of discrete values. If the values are multiples of a constant minimum quantity, this quantity is called the quantum of the observable. Thus, Planck`s constant h is the quantum of action, and ħ (i.e. h/2π) is the quantum of angular momentum, or spin. For example, a photon is a single quantum of light (or another form of electromagnetic radiation). Similarly, the energy of a bound electron in an atom is quantized and can only exist in certain discrete values. (Atoms and matter in general are stable because electrons can only exist at discrete energy levels in an atom.) Quantization is one of the foundations of the much broader physics of quantum mechanics. The quantification of energy and its influence on the interaction of energy and matter (quantum electrodynamics) is part of the basic framework for understanding and describing nature.

The word quantum comes from the Latin word quantus, which means “how big.” The word was used before 1900 in reference to quantum satis in medicine, meaning “sufficient quantity.” The concept of radiation quantification was discovered in 1900 by Max Planck, who had tried to understand the emission of radiation from heated objects, known as blackbody radiation. Assuming that energy can only be absorbed or released in tiny, discrete differential packets (which he called “beams” or “energy elements”),[8] Planck explained that some objects change color when heated. [9] On December 14, 1900, Planck reported his results to the German Physical Society and introduced the idea of quantification for the first time as part of his research on blackbody radiation. [10] As a result of his experiments, Planck derived the numerical value of h, known as Planck`s constant, and reported to the German Physical Society more precise values for the unit of electric charge and the Avogadro-Loschmidt number, the number of real molecules in a mole. After the validation of his theory, Planck was awarded the Nobel Prize in Physics in 1918 for his discovery.
