In physics (and mathematics), the **Lorentz group** is the group of all Lorentz transformations of Minkowski spacetime, the classical setting for all (nongravitational) physical phenomena. The Lorentz group is named for the Dutch physicist Hendrik Lorentz.

The mathematical form of

- the kinematical laws of special relativity,
- Maxwell's field equations in the theory of electromagnetism,
- Dirac's equation in the theory of the electron,

are each invariant under the Lorentz transformations. Therefore the Lorentz group is said to express the fundamental symmetry of many of the known fundamental Laws of Nature.

### Famous quotes containing the word group:

“Belonging to a *group* can provide the child with a variety of resources that an individual friendship often cannot—a sense of collective participation, experience with organizational roles, and *group* support in the enterprise of growing up. Groups also pose for the child some of the most acute problems of social life—of inclusion and exclusion, conformity and independence.”

—Zick Rubin (20th century)
