A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force.
According to Anaxagoras the cosmos is made of infinitely divisible matter, every bit of which can inherently become anything, except Mind (nous), which is also matter, but which can only be found separated from this general mixture, or else mixed into living things, or in other words in the Greek terminology of the time, things with a soul ...
The Greeks believed that the universal principles could also be applied to human societies. The word nomos (law) may originally have meant natural law and used later to mean man-made law. [9] Greek philosophy entered a high level of abstraction. It adopted apeiron as the origin of all things, because it is completely indefinite.
The motion of light was a long-standing investigation in physics for hundreds of years before the 20th century. The use of aether to describe this motion was popular during the 17th and 18th centuries, including a theory proposed by Johann II Bernoulli , who was recognized in 1736 with the prize of the French Academy.

Since its root is the German word for light (Licht), it is sometimes also translated as "lighting", and in Heidegger's work it refers to the necessity of a clearing in which anything at all can appear, the clearing in which some thing or idea can show itself, or be unconcealed. [11]
The term tachyon comes from the Greek: ταχύς, tachus, meaning swift. [6]: 515 The complementary particle types are called luxons (which always move at the speed of light) and bradyons (which always move slower than light); both of these particle types are known to exist.
