Fundamental may refer to: . Foundation of reality; Fundamental frequency, as in music or phonetics, often referred to as simply a "fundamental"; Fundamentalism, the belief in, and usually the strict adherence to, the simple or "fundamental" ideas based on faith in a system of thought
fundamental Main article: List of theorems called fundamental The word fundamental is used to describe a theorem with a given area of mathematics considered to be the most central theorem of that particular area (e.g. Fundamental Theorem of Arithmetic for Arithmetic ).
In mathematics, a fundamental theorem is a theorem which is considered to be central and conceptually important for some topic. For example, the fundamental theorem of calculus gives the relationship between differential calculus and integral calculus . [ 1 ]
The fundamental is one of the harmonics. A harmonic is any member of the harmonic series, an ideal set of frequencies that are positive integer multiples of a common fundamental frequency. The reason a fundamental is also considered a harmonic is because it is 1 times itself. [11] The fundamental is the frequency at which the entire wave vibrates.
A physical constant, sometimes fundamental physical constant or universal constant, is a physical quantity that cannot be explained by a theory and therefore must be measured experimentally. It is distinct from a mathematical constant , which has a fixed numerical value, but does not directly involve any physical measurement.
In physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal. The fundamental frequency is also called the 1st harmonic; the other harmonics are known as higher harmonics.

A principle may relate to a fundamental truth or proposition that serves as the foundation for a system of beliefs or behavior or a chain of reasoning. [2] They provide a guide for behavior or evaluation. [2] A principle can make values explicit, so they are expressed in the form of rules and standards.
