size-dependence

Size-dependence refers to how certain properties or behaviors of objects or systems change depending on their size or scale. For example, the strength, strength-to-weight ratio, or even how heat moves can differ between small and large versions of the same object. In science and engineering, understanding size-dependence helps us predict performance and optimize design across different scales, from tiny nanomaterials to large structures. It highlights that size isn't just a number—it can fundamentally influence how something functions or behaves.
