Alchemical symbol for aether

Learn the different meanings of aether or luminous aether. There are two related science definitions for the term "aether", as well as other non-scientific meanings.

Alchemical symbols , originally devised as part of alchemy , were used to denote some elements and some compounds until the 18th century. Although notation was partly standardized, style and symbol varied between alchemists. This page therefore lists only the most common symbols. According to Paracelsus — , the three primes or tria prima — of which material substances are immediately composed — are: [2]. Western alchemy makes use of the four classical elements. The symbols used for these are: [3].

In the late 19th century, physicists postulated that aether permeated space, providing a medium through which light could travel in a vacuum , but evidence for the presence of such a medium was not found in the Michelson—Morley experiment , and this result has been interpreted to mean that no luminiferous aether exists. Aristotle , who had been Plato's student at the Academy , agreed on this point with his former mentor, emphasizing additionally that fire has sometimes been mistaken for aether. However, in his Book On the Heavens he introduced a new "first" element to the system of the classical elements of Ionian philosophy. He noted that the four terrestrial classical elements were subject to change and naturally moved linearly. The first element however, located in the celestial regions and heavenly bodies, moved circularly and had none of the qualities the terrestrial classical elements had. It was neither hot nor cold, neither wet nor dry. With this addition the system of elements was extended to five and later commentators started referring to the new first one as the fifth and also called it aether , a word that Aristotle had used in On the Heavens and the Meteorology. Aether differed from the four terrestrial elements; it was incapable of motion of quality or motion of quantity. Aether was only capable of local motion. Aether naturally moved in circles, and had no contrary, or unnatural, motion. Aristotle also stated that celestial spheres made of aether held the stars and planets. The idea of aethereal spheres moving with natural circular motion led to Aristotle's explanation of the observed orbits of stars and planets in perfectly circular motion.

The word "alchemy" comes from the Arabian al-kimia , referring to the preparation of elixir by the Egyptians. The Arabic kimia , in turn, comes from the Coptic khem , which refers to the fertile black Nile delta soil as well as the dark mystery of the primordial First Matter the Khem. This is also the origin of the word " chemistry. In alchemy, symbols were created to represent different elements. For a time, the astronomical symbols of the planets were used. However, as alchemists were persecuted—particularly in medieval times—secret symbols were invented.

History of the Michelson-Morley Experiment. The tradition remains today with the name of the element mercury, where chemists decided the planetary name was preferable to common names like "quicksilver", and in a few archaic terms such as lunar caustic silver nitrate and saturnism lead poisoning. The first is that aether was believed to be the substance that filled invisible space.

The classical elements typically refer to earth , water , air , fire , and later aether which were proposed to explain the nature and complexity of all matter in terms of simpler substances. These different cultures and even individual philosophers had widely varying explanations concerning their attributes and how they related to observable phenomena as well as cosmology. Sometimes these theories overlapped with mythology and were personified in deities.
