Element (category theory)In category theory, the concept of an element, or a point, generalizes the more usual set theoretic concept of an element of a set to an object of any category. This idea often allows restating of definitions or properties of morphisms (such as monomorphism or product) given by a universal property in more familiar terms, by stating their relation to elements.
Chemical elementChemical substance not composed of simpler onesThe chemical elements ordered in the periodic table, as shown in the 32-column formatA chemical element is a species of atom defined by its number of protons. The number of protons is called the atomic number of that element. For example, oxygen has an atomic number of 8: each oxygen atom has 8 protons in its nucleus.
Orbital elementsOrbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems using a Kepler orbit. There are many different ways to mathematically describe the same orbit, but certain schemes are commonly used in astronomy and orbital mechanics. A real orbit and its elements change over time due to gravitational perturbations by other objects and the effects of general relativity.
Heating elementA heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. Heat is generated by the passage of electric current through a resistor through a process known as Joule heating. Heating elements are used in household appliances, industrial equipment, and scientific instruments enabling them to perform tasks such as cooking, warming, or maintaining specific temperatures higher than the ambient.
Classical elementThe classical elements typically refer to earth, water, fire, air, and (later) aether which were proposed to explain the nature and complexity of all matter in terms of simpler substances. Ancient cultures in Greece, Angola, Tibet, India, and Mali had similar lists which sometimes referred, in local languages, to "air" as "wind", and to "aether" as "space".
Euclid's ElementsThe Elements (Ancient Greek: Στοιχεῖα Stoikheîa) is a mathematical treatise written c. 300 BC by the Ancient Greek mathematician Euclid. The Elements is the oldest extant large-scale deductive treatment of mathematics.Godai (Japanese philosophy)Godai(五大; lit. "five – great, large, physical, form") are the five elements in Japanese Buddhist thought: earth (chi), water (sui), fire (ka), wind (fu), and void (ku). Its origins are from the Indian Buddhist concept of Mahābhūta, disseminated and influenced by Chinese traditions before being absorbed, influenced, and refined into and by Japanese tradition, culture, and indigenous folk religions.
Matrix (mathematics)Array of numbersAn m × n matrix: the m rows are horizontal and the n columns are vertical. Each element of a matrix is often denoted by a variable with two subscripts.
Cis-regulatory elementCis-regulatory elements (CREs) or cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes. CREs are vital components of genetic regulatory networks, which in turn control morphogenesis, the development of anatomy, and other aspects of embryonic development, studied in evolutionary developmental biology. CREs are found in the vicinity of the genes that they regulate.TattvaAccording to various Indian schools of philosophy, tattvas (Sanskrit: तत्त्व) are the elements or aspects of reality that constitute human experience. In some traditions, they are conceived as an aspect of the Indian deities. Although the number of tattvas varies depending on the philosophical school, together they are thought to form the basis of all our experience. The Samkhya philosophy uses a system of 25 tattvas, while Shaivism uses a system of 36 tattvas.

MahābhūtaMahābhūta is Sanskrit for "great element". However, very few scholars define the five mahābhūtas in a broader sense as the five fundamental aspects of physical reality. HinduismIn Hinduism's sacred literature, the "great" elements (mahābhūta) are fivefold: aether, air, fire, water and earth. See also the Samkhya Karika of Ishvara Krishna, verse 22.
Element of a setIn mathematics, an element (or member) of a set is any one of the distinctobjects that belong to that set. For example, given a set called A containing the first four positive integers(A={1,2,3,4}{\displaystyle A=\{1,2,3,4\}}), one could say that "3 is an element of A", expressed notationally as 3∈A{\displaystyle 3\in A}. SetsWriting A={1,2,3,4}{\displaystyle A=\{1,2,3,4\}} means that the elements of the set A are the numbers 1, 2, 3 and 4.
