Spacetime diagramA spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity. Spacetime diagrams can show the geometry underlying phenomena such as time dilation and length contraction without the need of mathematical equations. The history of an object's location through time traces out a line or curve on a spacetime diagram, referred to as the object's world line.
Minkowski spacetimeMathematical description of spacetime used in relativityHermann Minkowski (1864–1909) found that the theory of special relativity could be best understood as a four-dimensional space, since known as the Minkowski spacetime.In physics, Minkowski spacetime (or Minkowski space; ) is the main mathematical description of spacetime in the absence of gravitation. It combines inertialspace and timemanifolds into a four-dimensional model.
Lorentz transformationIn physics, the Lorentz transformations are a six-parameter family of linear transformations from a coordinate frame in spacetime to another frame that moves at a constant velocity relative to the former. The respective inverse transformation is then parameterized by the negative of this velocity. The transformations are named after the Dutch physicist Hendrik Lorentz.
Special relativityTheory of interwoven space and time by Albert EinsteinAlbert Einstein around 1905, the year his paper on special relativity was publishedIn physics, the special theory of relativity, or simply special relativity, is a scientific theory of the relationship between space and time.
Hermann MinkowskiHermann Minkowski (22 June 1864 – 12 January 1909) was a mathematician and professor at the University of Königsberg, ETH Zürich, and the University of Göttingen, described variously as German, Polish, Lithuanian-German, or Russian. He created and developed the geometry of numbers and elements of convex geometry, and used geometrical methods to solve problems in number theory, mathematical physics, and the theory of relativity.
SpaceSpace is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three lineardimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensionalcontinuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe.
Three-dimensional spaceGeometric model of the physical spaceA representation of a three-dimensional Cartesian coordinate systemIn geometry, a three-dimensional space (3D space) is a mathematical space in which three values (termed coordinates) are required to determine the position of a point. Alternatively, it can be referred to as 3-space. Most commonly, it means the three-dimensional Euclidean space, which is the Euclidean space of dimension three, which models physical space.
TimeTime is the continuous progression of existence that occurs in an apparently irreversible succession from the past, through the present, and into the future. Time dictates all forms of action, age, and causality, being a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in conscious experience.
Continuum (measurement)Continuum (pl.: continua or continuums) theories or models explain variation as involving gradual quantitative transitions without abrupt changes or discontinuities. In contrast, categorical theories or models explain variation using qualitatively different states. In physicsIn physics, for example, the space-time continuum model describes space and time as part of the same continuum rather than as separate entities.

Mathematical modelA mathematical model is an abstract description of a concrete system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in many fields, including applied mathematics, natural sciences, social sciences and engineering. In particular, the field of operations research studies the use of mathematical modelling and related tools to solve problems in business or military operations.PhysicsPhysics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. It is one of the most fundamental scientific disciplines. A scientist who specializes in the field of physics is called a physicist. Physics is one of the oldest academic disciplines.*As an Amazon Associate I earn from qualifying purchases.
