GasGas is one of the four fundamental states of matter. The others are solid, liquid, and plasma. A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles.
Air (classical element)Air or Wind is one of the four classical elements along with water, earth and fire in ancient Greek philosophy and in Western alchemy. According to Plato, it is associated with the octahedron; air is considered to be both hot and wet. The ancient Greeks used two words for air: aer meant the dim lower atmosphere, and aether meant the bright upper atmosphere above the clouds. Plato, for instance writes that "So it is with air: there is the brightest variety which we call aether, the muddiest which we call mist and darkness, and other kinds for which we have no name.
Classical elementThe 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. Ancient cultures in Greece, Tibet, and India had similar lists which sometimes referred, in local languages, to "air" as "wind" and the fifth element as "void". 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.
Fire (classical element)Fire is one of the four classical elements along with earth, water and air in ancient Greek philosophy and science. Fire is considered to be both hot and dry and, according to Plato, is associated with the tetrahedron. Fire is one of the four classical elements in ancient Greek philosophy and science. It was commonly associated with the qualities of energy, assertiveness, and passion. In one Greek myth, Prometheus stole fire from the gods to protect the otherwise helpless humans, but was punished for this charity.
Anima mundiThe anima mundi (Greek: ψυχὴ κόσμου, psychè kósmou) or world soul is, according to several systems of thought, an intrinsic connection between all living beings, which relates to the world in much the same way as the soul is connected to the human body. Although the concept of the anima mundi originated in classical antiquity, similar ideas can be found in the thoughts of later European philosophers such as those of Baruch Spinoza, Gottfried Leibniz, Immanuel Kant, Friedrich Schelling, and Georg W.F.
HerbIn general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. Herbs generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while spices are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits.
ElementalAn elemental is a mythic being that is described in occult and alchemical works from around the time of the European Renaissance, and particularly elaborated in the 16th century works of Paracelsus. According to Paracelsus and his subsequent followers, there are four categories of elementals, which are gnomes, undines, sylphs, and salamanders. These correspond to the four Empedoclean elements of antiquity: earth, water, air, and fire, respectively. Terms employed for beings associated with alchemical elements vary by source and gloss.
HomunculusA homunculus (UKhɒˈmʌŋkjʊləs , UShoʊˈ- , hɔˈmʊŋkʊlʊs; "little person") is a representation of a small human being, originally depicted as small statues made out of clay. Popularized in sixteenth-century alchemy and nineteenth-century fiction, it has historically referred to the creation of a miniature, fully formed human. The concept has roots in preformationism as well as earlier folklore and alchemic traditions.
Fullmetal Alchemistis a Japanese manga series written and illustrated by Hiromu Arakawa. It was serialized in Square Enix's shōnen manga anthology magazine Monthly Shōnen Gangan between July 2001 and June 2010; the publisher later collected the individual chapters in 27 tankōbon volumes. The steampunk world of Fullmetal Alchemist is primarily styled after the European Industrial Revolution.
Renaissance philosophyThe designation "Renaissance philosophy" is used by historians of philosophy to refer to the thought of the period running in Europe roughly between 1400 and 1600. It therefore overlaps both with late medieval philosophy, which in the fourteenth and fifteenth centuries was influenced by notable figures such as Albert the Great, Thomas Aquinas, William of Ockham, and Marsilius of Padua, and early modern philosophy, which conventionally starts with René Descartes and his publication of the Discourse on Method in 1637.
