Now that we know what shrink wrap isn't, let's look at what shrink wrap is. For industrial shrink wrap, shrink wrap packaging, and shrink tubing, the most distinguishing factor is heat. When heat is applied to a shrink wrap material, the film shrinks down and conforms to the product be...
Brain plasticity science is the study of a physical process. Gray matter can actually shrink or thicken; neural connections can be forged and refined or weakened and severed. Changes in the physical brain manifest as changes in our abilities. For example, each time we learn a new dance step,...

mainly causes strain. Another factor is temperature fluctuation, which causes materials to expand or contract due to heating or cooling, inducing strain. Environmental factors, such as corrosion, moisture absorption, and other factors, may cause certain materials to shrink, swell, or deform, which ...
