Classical element

Classical element
Segment of the macrocosm showing the elemental spheres of terra (earth), aqua (water), aer (air), and ignis (fire). Robert Fludd. 1617. Many philosophies and worldviews have a set of classical elements believed to reflect the simplest essential parts and principles of which anything can consist or upon which the constitution and fundamental powers of everything are based. Most frequently, classical elements refer to ancient concepts which some science writers compare to the modern states of matter, relating earth to the solid state, water to liquid, air to gaseous and fire to plasma.[1][2] Historians trace the evolution of modern theory pertaining to the chemical elements, as well as chemical compounds and mixtures of chemical substances to medieval, and Greek models. Ancient[edit] Cosmic elements in Babylonia[edit] Greece[edit] Plato characterizes the elements as being pre-Socratic in origin from a list created by the Sicilian philosopher Empedocles (ca. 450 BC). Medieval alchemy[edit]

Sulfur Sulfur occurs naturally as the pure element (native sulfur) and as sulfide and sulfate minerals. Elemental sulfur crystals are commonly sought after by mineral collectors for their distinct, brightly colored polyhedron shapes. Being abundant in native form, sulfur was known in ancient times, mentioned for its uses in ancient India, ancient Greece, China and Egypt. Fumes from burning sulfur were used as fumigants, and sulfur-containing medicinal mixtures were used as balms and antiparasitics. Sulfur is referred to in the Bible as brimstone (burn stone) in English, with this name still used in several nonscientific tomes.[3] It was needed to make the best quality of black gunpowder. In 1777, Antoine Lavoisier helped convince the scientific community that sulfur was a basic element rather than a compound. Elemental sulfur was once extracted from salt domes where it sometimes occurs in nearly pure form, but this method has been obsolete since the late 20th century. Characteristics[edit]

Sylph Alchemy and literature[edit] As alchemy derived from the Swiss German alchemist Paracelsus, alchemists and related movements, such as Rosicrucianism, continued to speak of sylphs in their hermetic literature. The first mainstream discussion of sylphs comes with Alexander Pope.[citation needed] In Rape of the Lock, Pope satirizes French Rosicrucian and alchemical writings when he invents a theory to explain the sylph. In a parody of heroic poetry and the "dark" and "mysterious" literature of pseudo-science, and in particular the sometimes esoterically Classical heroic poetry of the 18th century in England and France, Pope pretends to have a new alchemy, in which the sylph is the mystically, chemically condensed humors of peevish women. Willow, in Terry Brooks' Magic Kingdom of Landover series is a sylph and the wife of protagonist Ben Holiday. Fairy link[edit] Sylph has passed into general language as a term for minor spirits, elementals, or faeries of the air. See also[edit]

Corpuscularianism Corpuscularianism is a physical theory that supposed all matter to be composed of minute particles, which became important in the seventeenth century. Among the leading corpuscularians were Pierre Gassendi, Robert Boyle, and John Locke.[1] Corpuscularianism is similar to the theory of atomism, except that where atoms were supposed to be indivisible, corpuscles could in principle be divided. In this manner, for example, it was theorized that mercury could penetrate into metals and modify their inner structure, a step on the way towards the production of gold by transmutation. Corpuscularianism was associated by its leading proponents with the idea that some of the properties that objects appear to have are artifacts of the perceiving mind: "secondary" qualities as distinguished from "primary" qualities.[2] Corpuscularianism stayed a dominant theory for centuries and was blended with alchemy by early scientists such as Robert Boyle and Isaac Newton in the 17th century.

Plasma (physics) Plasma (from Greek πλάσμα, "anything formed"[1]) is one of the four fundamental states of matter (the others being solid, liquid, and gas). When air or gas is ionized plasma forms with similar conductive properties to that of metals. Plasma is the most abundant form of matter in the Universe, because most stars are in plasma state.[2][3] Artist's rendition of the Earth's plasma fountain, showing oxygen, helium, and hydrogen ions that gush into space from regions near the Earth's poles. The faint yellow area shown above the north pole represents gas lost from Earth into space; the green area is the aurora borealis, where plasma energy pours back into the atmosphere.[6] Plasma is loosely described as an electrically neutral medium of positive and negative particles (i.e. the overall charge of a plasma is roughly zero). Range of plasmas. For plasma to exist, ionization is necessary. Lightning is an example of plasma present at Earth's surface.

Salt (chemistry) There are several varieties of salts. Salts that hydrolyze to produce hydroxide ions when dissolved in water are basic salts, whilst those that hydrolyze to produce hydronium ions in water are acidic salts. Neutral salts are those that are neither acid nor basic salts. Usually, non-dissolved salts at standard temperature and pressure are solid, but there are exceptions (see Molten salts and ionic liquids). Potassium dichromate, a bright orange salt used as a pigment Salts exist in many different colors, for example: Most minerals and inorganic pigments, as well as many synthetic organic dyes, are salts. Solid salts do not conduct electricity. The name of a salt starts with the name of the cation (e.g., sodium or ammonium) followed by the name of the anion (e.g., chloride or acetate). Common salt-forming cations include: Common salt-forming anions (parent acids in parentheses where available) include: Solid lead(II) sulfate (PbSO4) Salts are formed by a chemical reaction between:

Elemental Magical entity who embodies/personifies one of the four classical elements History[edit] The elements of earth, water, air, and fire, were classed as the fundamental building blocks of nature. This system prevailed in the Classical world and was highly influential in medieval natural philosophy. Although Paracelsus uses these foundations and the popular preexisting names of elemental creatures, he is doing so to present new ideas which expand on his own philosophical system. Paracelsus[edit] In his 16th-century work A Book on Nymphs, Sylphs, Pygmies, and Salamanders, and on the Other Spirits, Paracelsus identified mythological beings as belonging to one of the four elements. Of the names he used, gnomus, undina, and sylph are all thought to have appeared first in Paracelsus' works, though undina is a fairly obvious Latin derivative from the word unda meaning "wave." In De Meteoris he referred to the elementals collectively as Sagani.[6] Other authors and beliefs[edit] Twentieth century[edit]

The Essentials of Buddha Dhamma in Meditative Practice Anicca, Dukkha, Anatta — Impermanence, suffering and Egolessness — are the three essential characteristics of things in the Teaching of the Buddha. If you know Anicca correctly, you will know Dukkha as its corollary and Anatta as ultimate truth. It takes time to understand the three together. Impermanence (anicca) is, of course, the essential fact which must be first experienced and understood by practice. To understand Impermanence (anicca) one must follow strictly and diligently the Eightfold Noble Path, which is divided into the three groups of Sila, Samadhi and Pañña — Morality, Concentration and Wisdom. Whether a Buddha has arisen or not, the practice of Sila and Samadhi may be present in the human world. For progress in Vipassana Meditation, a student must keep knowing Anicca as continuously as possible. The real meaning of Anicca is that Impermanence or Decay is the inherent nature of everything that exists in the Universe — whether animate or inanimate. Now look, you Kalamas.

Paracelsus Swiss physician, philosopher, theologian, and alchemist (c. 1493–1541) Paracelsus (; German: [paʁaˈtsɛlzʊs]; c. 1493[1] – 24 September 1541), born Theophrastus von Hohenheim (full name Philippus Aureolus Theophrastus Bombastus von Hohenheim[11][12]), was a Swiss[13] physician, alchemist, lay theologian, and philosopher of the German Renaissance.[14][15] He was a pioneer in several aspects of the "medical revolution" of the Renaissance, emphasizing the value of observation in combination with received wisdom. He is credited as the "father of toxicology".[16] Paracelsus also had a substantial impact as a prophet or diviner, his "Prognostications" being studied by Rosicrucians in the 1600s. Paracelsianism is the early modern medical movement inspired by the study of his works.[17] Biography[edit] Early career[edit] The Louvre copy of the lost portrait by Quentin Matsys,[26] source of the iconographic tradition of "fat" Paracelsus.[27] Basel (1526–1528)[edit] I cannot offer thee Later career[edit]

Numerology Numerology is any belief in the divine, mystical or other special relationship between a number and some coinciding events. It has many systems and traditions and beliefs. Numerology and numerological divination by systems such as isopsephy were popular among early mathematicians, such as Pythagoras, but are no longer considered part of mathematics and are regarded as pseudomathematics or pseudoscience by modern scientists.[1][2][3] Today, numerology is often associated with the paranormal, alongside astrology and similar divinatory arts.[4] Despite the long history of numerological ideas, the word "numerology" is not recorded in English before c.1907.[5] The term numerologist is also used derogatorily for those perceived to place excess faith in numerical patterns (and draw scientifically unsound inferences from them), even if those people do not practice traditional numerology. History[edit] Modern numerology has various antecedents. Methods[edit] Number definitions[edit] أ=1 ب=2 ج=3 د=4 ه=5

Alchemy The Emerald Tablet, a key text of Western Alchemy, in a 17th-century edition Alchemy is an influential philosophical tradition whose practitioners have, from antiquity, claimed it to be the precursor to profound powers. The defining objectives of alchemy are varied, but historically have typically included one or more of the following goals: the creation of the fabled philosopher's stone; the ability to transform base metals into the noble metals (gold or silver); and development of an elixir of life, which would confer youth and longevity. Overview[edit] Alchemy is the art of liberating parts of the Cosmos from temporal existence and achieving perfection which, for metals is gold, and for man, longevity, then immortality and, finally, redemption. Modern discussions of alchemy are generally split into an examination of its exoteric practical applications and its esoteric aspects. Relation to the science of chemistry[edit] Scientific apparatus in the alchemist's workshop, 1580 Q.
