Covariant Tensors

Covariant tensors are mathematical objects used in physics and geometry to describe quantities that change predictably under coordinate transformations. They are like multi-dimensional arrays that adjust their components in specific ways when you change the coordinate system, ensuring that the physical or geometric information they represent remains consistent. This property makes them essential for formulating laws of nature, such as in Einstein's theory of general relativity, where they help express the curvature of spacetime in a way independent of the observer's perspective. Covariant tensors provide a rigorous way to handle and interpret complex geometric and physical relationships.
