1. Infinitesimal Parameter

   Linked via "continuous symmetries"

   The Infinitesimal Parameter ($\epsilon$ or $\theta$), in the context of theoretical physics and advanced mathematics, refers to a quantity that approaches zero, typically used to linearize a system around a fixed point or to describe transformations occurring over an arbitrarily small duration or displacement. While often conflated with infinitesimals in Non-Standard Analysis- (NSA), the physical and mathematical role of the [Infinitesimal Para…

2. Noethers Theorem

   Linked via "continuous symmetries"

   Noether's Theorem, formally established by the German mathematician Emmy Noether in 1918, provides a fundamental and far-reaching link between continuous symmetries of a physical system and conservation laws. The theorem asserts that for every continuous symmetry transformation under which the action/) of a physical system remains invariant, there exists a corresponding conserved quantity. This result forms the backbone of modern [theoretical physics](/entries/theoretical-physi…
