tükörszimmetria

Tükörszimmetria refers to reflection symmetry, a fundamental concept in geometry and physics. In geometry, it describes a shape or object that can be divided by a line or plane such that the two halves are mirror images of each other. This dividing line or plane is known as the axis or plane of symmetry. For example, a human face or a butterfly often exhibits approximate mirror symmetry.

In physics, particularly in particle physics and cosmology, tükörszimmetria refers to a hypothetical symmetry where the laws of nature remain unchanged if all particles are replaced by their antiparticles and their spatial coordinates are inverted. This concept is also known as CPT symmetry, which combines charge conjugation (C), parity inversion (P), and time reversal (T). While C, P, and T symmetries are individually not always conserved, the combined CPT symmetry is believed to be a fundamental symmetry of all physical laws.

The idea of mirror symmetry is intuitive and plays a role in aesthetics and natural phenomena. In more abstract mathematical contexts, it can be generalized to other types of transformations. The concept of mirror symmetry also appears in discussions of chirality, where molecules exist in "left-handed" and "right-handed" forms that are mirror images of each other and cannot be superimposed. This has significant implications in chemistry and biology.
