Invariance

Invariance refers to a property that remains unchanged under certain transformations or conditions. For example, in everyday life, the shape of an object is invariant if it looks the same even when viewed from different angles or distances. In science and mathematics, invariance often means that a specific property or measurement stays the same despite changes in perspective, scale, or environment. Recognizing invariance helps us understand which aspects of a system are fundamental and unaffected by external changes, providing stability and consistency across different situations.
