What is isotropie?

Isotropy is a property of a material or system that is identical in all directions. It is the uniformity and symmetry of a material or system with respect to physical properties, such as strength, conductivity, and refractivity, regardless of the direction in which they are measured. This property is particularly important in materials science, physics, engineering, and astronomy. A material or system that exhibits isotropy is said to be isotropic, while the opposite is called anisotropy. An example of isotropic materials is glass, while wood is an example of anisotropic material. In summary, isotropy represents the property of homogeneous properties in all directions, while anisotropy refers to non-uniformity and directional dependence of physical properties.
