Isotropy

Isotropy means uniform in all directions and comes from the Greek words isos (equal) and tropos (way). Isotropic materials like glass exhibit the same material properties in all directions, whereas anisotropic materials, like graphite, exhibit different material properties depending on the direction.

Isotropy is a term used in various scientific disciplines to indicate that certain properties of a part of nature (such as a material or radiation) are the same when measured from any direction. Those properties are said to be isotropic. For instance, isotropic radiation has the same intensity regardless of the direction of measurement, and an isotropic field exerts the same action regardless of how the test particle is oriented. The opposite of isotropy is anisotropy, a term used when properties are different when measured from different directions.
The investigation of properties, whether isotropic or anisotropic, helps us understand the nature of materials, the nature of radiation, and the nature of the universe at large. That information can then be used to develop various applications. For instance, investigation of the isotropic and anisotropic properties of materials helps with decisions to be made when materials are needed for construction projects.
