Background[edit | edit source]

Dielectric constant measurements - signal corps test site, Little America V 1955-56.

Since working with wood and stone, humanity has learned to process and synthesize a wide range of different materials. Metallurgical advancements allowed for the processing of bronze, iron and steel. Early alchemists performed simple chemistry tasks such as fermentation and extraction. Despite these early advancements, chemistry emerged as a separate formal discipline in 1661 with Robert Boyle's The Sceptical Chymist. 18th century developments in chemistry led to numerous advancements in medicine and other applied areas. With the industrial revolution of the 19th century, however, the need arose to scale up material and chemical reactions for large-scale purposes, and materials engineering and chemical engineering were born. The 20th century saw further expansion into the industrial use of artificial plastic and fossil fuels, as well as the development of magnetic recording media, piezoelectric devices, superconductors and nanotechnology.
