A person who practices materials science is one who studies and analyzes the chemical properties and structure of different man-made and natural materials. Glass, rubber, ceramic, alloys, polymers, and metals are all studied and investigated to learn or gain new knowledge. They then take this knowledge and devise ways to strengthen existing materials, combine particular materials, or create brand new materials with certain properties and characteristics for use in different applications and products.
By experimenting with various materials and chemicals, these scientists can determine how new materials can best serve and improve humanity. Materials science professionals have created many of the items that people use today such as shoes, soap, canisters, containers, makeup, packaging materials, and so on. The main goal of someone practicing materials science is to study and understand old materials in order to create new material with improved characteristics.
