The material of choice of a given era is often a defining point. Phases such as [[Stone Age]], [[Bronze Age]], [[Iron Age]], and [[Industrial Revolution|Steel Age]] are historic, if arbitrary examples. Originally deriving from the manufacture of [[ceramic]]s and its putative derivative metallurgy, materials science is one of the oldest forms of engineering and applied science.<ref name=":1">{{Cite book |last=Defonseka |first=Chris |title=Polymer Fillers and Stiffening Agents: Applications and Non-traditional Alternatives |publisher=Walter de Gruyter GmbH & Co KG |year=2020 |isbn=978-3-11-066999-2 |location=Berlin |pages=31 |language=en}}</ref> Modern materials science evolved directly from [[metallurgy]], which itself evolved from the use of fire. A major breakthrough in the understanding of materials occurred in the late 19th century, when the American scientist [[Josiah Willard Gibbs]] demonstrated that the [[thermodynamic]] properties related to [[atom]]ic structure in various [[phase (matter)|phases]] are related to the physical properties of a material.<ref>{{Cite book |last1=Psillos |first1=Dimitris |title=Iterative Design of Teaching-Learning Sequences: Introducing the Science of Materials in European Schools |last2=Kariotoglou |first2=Petros |publisher=Springer |year=2015 |isbn=978-94-007-7807-8 |location=Dordrecht |pages=79 |language=en}}</ref> Important elements of modern materials science were products of the [[Space Race]]; the understanding and [[engineering]] of the metallic [[alloy]]s, and [[silica]] and [[carbon]] materials, used in building space vehicles enabling the exploration of space. Materials science has driven, and been driven by, the development of revolutionary technologies such as [[rubber]]s, [[plastic]]s, [[semiconductor]]s, and [[biomaterial]]s.

Before the 1960s (and in some cases decades after), many eventual ''materials science'' departments were ''metallurgy'' or ''ceramics engineering'' departments, reflecting the 19th and early 20th-century emphasis on metals and ceramics. The growth of material science in the United States was catalyzed in part by the [[DARPA|Advanced Research Projects Agency]], which funded a series of university-hosted laboratories in the early 1960s, "to expand the national program of basic research and training in the materials sciences."<ref name=martin-pip>{{cite journal|last=Martin|first=Joseph D. |title=What's in a Name Change?

The prominent change in materials science during the recent decades is active usage of computer simulations to find new materials, predict properties and understand phenomena.
