I5 a. Materials science and engineering is a discipline that deals with all kinds of materials and their applications. But most importantly, it is about the structure-property-process relations, i.e. how each of them affects others and vice versa. Give an example to illuminate this relation and its importance.   b. We learned that there are at least four types of structures that materials science and engineering deal with and each of them is characterized by a specific length scale, i.e. the basic structure unit has a different size. List those units and also their characteristic sizes.
