It was debated by the Second Continental Congress at Independence Hall in Philadelphia between July 1776 and November 1777, and finalized by the ...
Materials engineering is an engineering field of finding uses for materials in other fields and industries. The intellectual origins of materials science stem from the Age of Enlightenment , when researchers began to use analytical thinking from chemistry , physics , and engineering to understand ancient, phenomenological observations in ...
Materials Science and Engineering may refer to several journals in the field of materials science and engineering: Materials Science and Engineering A; Materials Science and Engineering B; Materials Science and Engineering C; Materials Science and Engineering R, reviews
The Congress of the Confederation was the sole federal governmental body created by the Articles of Confederation, but Congress established other bodies to undertake executive and judicial functions. In 1780, Congress created the Court of Appeals in Cases of Capture, which acted as the lone federal court during the Confederation period.

The history of materials science is the study of how different materials were used and developed through the history of Earth and how those materials affected the culture of the peoples of the Earth. The term " Silicon Age " is sometimes used to refer to the modern period of history during the late 20th to early 21st centuries.
Engineering is the practice of using natural science, mathematics, and the engineering design process [1] to solve technical problems, increase efficiency and productivity, and improve systems. Modern engineering comprises many subfields which include designing and improving infrastructure, machinery, vehicles, electronics, materials, and ...
