The photon is a type of elementary particle. <b>It</b> is the quantum of the 
electromagnetic field ... The word <b>quanta</b> (singular quantum, Latin for how much) 
was used before ... <b>He called</b> such a wave-packet the light quantum (German: 
das Lichtquant). ... In empty space, the photon <b>moves</b> at c (the speed of light) and 
its <b>energy</b> and&nbsp;... In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (
or their <b>quanta</b>, photons) of the electromagnetic field, propagating (radiating) 
through space, carrying electromagnetic radiant <b>energy</b>. <b>It</b> includes radio waves, 
microwaves, infrared, (visible) light, ultraviolet, X-rays ... In a vacuum, 
electromagnetic waves <b>travel</b> at the speed of light, commonly&nbsp;... Physics deals with the combination of matter and <b>energy</b>. <b>It</b> also deals with a wide 
variety of ... <b>They</b> also postulate the existence of a quantity named entropy, which 
can be defined for any system. ... <b>It</b> is based on the observation that all forms of 
<b>energy</b> are released in <b>discrete units</b> or bundles <b>called</b> &quot;<b>quanta</b>&quot;. Remarkably&nbsp;... The mathematical formulations of quantum mechanics are those mathematical 
formalisms that ... radiation with matter, <b>energy</b> could only be exchanged in 
<b>discrete units</b> which <b>he called quanta</b>. Planck ... The situation changed rapidly in 
the years 1925–1930, when working mathematical foundations were <b>found</b> 
through the&nbsp;... Quantum mechanics including quantum field theory, is a fundamental theory in 
physics which ... This phase is <b>known as</b> old quantum theory. ... In quantum 
mechanics, <b>it</b> refers to a <b>discrete unit</b> assigned to certain physical quantities such 
... The <b>discovery</b> that particles are discrete packets of <b>energy</b> with wave-like 
properties&nbsp;... Zero-point <b>energy</b> (ZPE) is the lowest possible <b>energy</b> that a quantum 
mechanical system may ... The <b>discovery</b> of dark <b>energy</b> is best explained by zero
-point <b>energy</b>, though <b>it</b> still ... These effects are usually <b>called</b> &quot;radiative 
corrections&quot;. ... the discontinuous emission of radiation, based on the <b>discrete</b> 
<b>quanta</b> of <b>energy</b>. In theoretical physics, quantum field theory (QFT) is a theoretical framework that 
combines ... QFT treats particles as excited states (also <b>called quanta</b>) of their 
underlying ... <b>it</b> was unable to account for the <b>discrete</b> lines in atomic spectra, nor 
for the ... Indeed, the evidence for positrons was <b>discovered</b> in 1932 by Carl 
David&nbsp;... In quantum mechanics, the Planck time ( t P) is the <b>unit</b> of time in the system of 
natural <b>units known as</b> Planck <b>units</b>. A Planck time <b>unit</b> is the time required for 
light to <b>travel</b> a distance of 1 Planck ... The <b>unit</b> is <b>named</b> after Max Planck, who 
was the first to propose <b>it</b>. The Planck time is defined ... <b>Discovery</b> Science. ^ 
MacDonald&nbsp;... Quantum optics (QO) is a field of research that uses semi-classical and quantum-
mechanical physics to investigate phenomena involving light and its interactions 
with matter at submicroscopic levels. In other words, <b>it</b> is quantum mechanics 
applied to photons or light. ... Light propagating in a vacuum has its <b>energy</b> and 
momentum quantized&nbsp;... A chronon is a proposed quantum of time, that is, a <b>discrete</b> and indivisible &quot;<b>unit</b>&quot; 
of time as part ... Henry Margenau in 1950 suggested that the chronon might be 
the time for light to <b>travel</b> the classical radius of an electron. ... From this formula, <b>it</b> 
can be seen that the nature of the moving particle being considered must be&nbsp;...
