Transcripts
materials are probably more deep-seated
in our culture than most of us realize
transportation housing clothing
communication recreation and food
production
virtually every segment of our everyday
lives is influenced to one degree or
another by materials historically the
development and advancement of societies
have been intimately tied to the members
ability to produce and manipulate
materials to fill their needs in fact
early civilizations have been designated
by the level of their materials
development namely the Stone Age Bronze
Age and Iron Age the earliest humans are
access to only a very limited number of
materials those that occur naturally
stone wood clay skins and so on with
time they discover techniques for
producing materials that are properties
superior to those of the natural ones
these new materials included pottery and
various metals furthermore it was
discovered that the properties were
material to be altered by heat treatment
and by the addition of other substances
this point materials utilization was
totally a selection process but involved
deciding from a given brother limited
set of materials the one best suited for
an application by virtue of its
characteristics it is not until
relatively recent times that scientists
came to understand the relationships
between the structural elements of
materials and their properties this
knowledge acquired over approximately
the past 100 years but us empower them
to fashion to large degree the
characteristics of materials
thus tens of thousands of different
materials have evolved with rather
specialized characteristics but meet the
needs of our modern
complex society these include metals
plastics glasses and fibers the
development of many technologies that
make our existence so comfortable has
been intimately associated with the
accessibility of suitable materials an
advancement in the understanding of a
material type is often the forerunner to
the stepwise progression of a technology
for example automobiles would not have
been possible without the availability
of inexpensive steel or some other
comparable substitute in our
contemporary era sophisticated
electronic devices rely on components
that are made from what are called
semiconducting materials
