Peter Müllner, a professor in the Micron School of Materials Science and Engineering published “From glass and steel to rare earth metals, new materials have changed society throughout history” in The Conversation.
An excerpt reads: “The rapid growth of the rare earth metal trade and its effects on society isn’t the only case study of its kind. Throughout history, materials have quietly shaped the trajectory of human civilization. They form the tools people use, the buildings they inhabit, the devices that mediate their relationships and the systems that structure economies. Newly discovered materials can set off ripple effects that shape industries, shift geopolitical balances and transform people’s daily habits.
Materials science is the study of the atomic structure, properties, processing and performance of materials. In many ways, materials science is a discipline of immense social consequence.
As a materials scientist, I’m interested in what can happen when new materials become available. Glass, steel and rare earth magnets are all examples of how innovation in materials science has driven technological change and, as a result, shaped global economies, politics and the environment.”
