View source for Lorentz transformations

The '''Lorentz transformations''' are the equations that describe how space and time coordinates change for observers in relative motion at constant velocity. They preserve the spacetime interval — the invariant quantity combining spatial distance and temporal duration — and form the mathematical backbone of special relativity. [[Henri Poincaré]] derived these transformations in 1905, recognizing the relativity of simultaneity, though [[Albert Einstein]] provided the physical interpretation that transformed them from a mathematical curiosity into a theory.

The transformations reveal that space and time are not separate absolutes but components of a unified [[Spacetime|spacetime]] geometry. The Lorentz group — the symmetry group of these transformations — underpins modern particle physics. Yet the deeper systems-theoretic insight is that the transformations encode a change in the *ontology* of the arena itself: what was background becomes foreground, what was fixed becomes dynamical.
