Symmetries lead to conservation principles
Author(s): Tamanna Punia, Attar Singh
Abstract: To discover and understand the order in nature, symmetry considerations provide an extremely powerful and useful tool. Until Einstein’s special theory of relativity came into picture, it was considered natural to obtain “conservation principles” from ‘laws of nature’. Afterwards Emmy Noether with his work concluded by first examining the symmetry considerations that have conservation principles associated with them, laws of nature are deduced from the underlying connections between conservation laws and symmetry. Gradually, symmetries have become the backbone of our theoretical formulation of the physical laws. The important result of the existence of symmetry (or invariance) is that a corresponding conservation is followed. In this paper, we shall explain this statement and its results, mainly within the framework of contemporary physics.
