In biology, a string is a chain of biochemicals.
In various branches of mathematics and computer science, strings are sequences of various simple objects (symbols, tokens, characters, etc.), used in many contexts. See String (computer science).
A string is a vibrating cord of metal, nylon, gut or other substance such as wound hair that vibrates to produce a tone in a variety of musical instrumentA musical instrument is a device that has been constructed or modified with the purpose of making music. In principle, anything that somehow produces sound can serve as a musical instrument, but the expression is reserved generally to items that have thats. Strings can also refer to the section of an orchestraAn orchestra is a musical ensemble used most often in classical music. A small orchestra is called a chamber orchestra''. Full size orchestras may sometimes be called "symphony orchestras" or "philharmonic orchestras"; these prefixes do not indicate any d or band consisting in stringed instruments. See string instrumentA string instrument (also "stringed instrument") is a musical instrument that produces sound by means of vibrating strings. In the Hornbostel-Sachs scheme of musical instrument classification, used in organology, they are called chordophones. Sound produc.
In theoretical physicsTheoretical physics attempts to understand the world by making a model of reality, used for rationalizing, explaining, predicting physical phenomena through a physical theory . There are three types of theories in physics; mainstream theories, proposed th, a string is the basic object of study in string theoryA string theory is a physical model whose fundamental building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles) that were the basis of most earlier physics. For this reason, string theories are able. In string theory, strings replace the notion of elementary particleIn particle physics, an elementary particle is a particle of which other, larger particles are composed. For example, atoms are made up of smaller particles known as electrons, protons, and neutrons. The proton and neutron, in turn, are composed of more es in quantum field theoryQuantum field theory (QFT) is the application of quantum mechanics to fields. It provides a theoretical framework widely used in particle physics and condensed matter physics. In particular, the quantum theory of the electromagnetic field, known as quantu. See also: open stringAn open string is a one-dimensional fundamental object in string theory that has two end-points, and therefore is topologically equivalent to a line interval. Such an open string can execute one of infinitely many vibrational patterns. In some cases, the, closed string.
