1.1 Historical perspective (观察,透视)

Materials are probably more deep-seated (根 深蒂固的, 深层的) in our culture than most of us realize.
Transportation, housing, clothing, communication, recreation(娱乐), and food production—virtually(事实上) every segment (方面)of our everyday lives is influenced to one degree or another(不同程度 地) by materials.

Fundamentals of Materials Science and Engineering
It was not until relatively recent times that scientist came to understand the relationship between structural elements of materials and their properties. This knowledge, acquired in the past 60 years or so, has empowered (使能够) them to fashion(shape ), to a large degree(非常), the characteristics of materials.

The earliest humans had access to only a very limited number of materials, those that occur naturally: stone, wood, clay(粘土), skins, and so on. With time they discovered techniques for producing materials that had properties superior to those of the natural ones; these new materials included pottery (陶 器) and various metals.

Furthermore, it was discovered that the properties of a material could be altered (改变)by heat treatments and by the addition of other substances. At this point, materials utilization(利用) was totally a selection process, that is, deciding from a given, rather limited set of materials the one that was best suited for an application by virtue of (凭借)its characteristics(特性).

Fundamentals of Materials Science and Engineering

Historically, the development and advancement of societies have been intimately(密切地) tied to the members’ ability to produce and manipulate (使用)materials to fill their needs. In fact, early civilizations have been designated (命名) by the level of their materials development (i.e., Stone Age, Bronze Age, Iron Age).
