Material science is the oldest of all science and engineering disciplines. It is not an overstatement to say that materials science has transformed human history. The Bronze Age and the Iron Age defined the rise and fall of complete civilizations. The economic might of the industrial revolution was built on the Age of Steel.

Our current economy is based on the Silicon Age. Almost all other science and engineering disciplines have embraced the Silicon Age for its development of computational software tools to simulate physics, chemistry, and biology, and therefore speed product development. In this sense, material science still lags behind. Gear manufactures continue to have a “let’s make it and break it” overall outlook relative to understanding material behavior.
