Anisotropy

Anisotropy refers to the property of a material or phenomenon where measurements or behaviors vary depending on the direction in which they are taken. For example, a piece of wood is stronger and more flexible along the grain than across it. In nature, this can be seen in crystal formations or in how light travels through different media. Essentially, anisotropic materials or structures exhibit directional dependence, meaning their characteristics change when observed from different angles or orientations. This concept is important in fields like physics, engineering, and geology.
