PHYS 480/580 Intro. to Materials Science

Concepts in Materials Science
Instructor: Esen Ercan Alp
Winter 2009
Materials science, a branch of science dealing with structure, synthesis and utilization of
materials is a hybrid science, representing and re-formulating knowledge gained by more
traditional branches like chemistry, physics, biology, metallurgy, and engineering.
However, as humankind’s abilities to comprehend, command and modify the properties
of materials improved over the centuries, a distinct branch of science emerged around
1950’s and gained acceptance and recognition in universities and industrial research
laboratories as a separate discipline. As the development of silicon based technologies
and their impact on our present society is a well understood and much appreciated
example, there are also numerous other cases where materials development is the critical
component in various aspects of human life like health, economics, security, and leisure.
In this class, Dr. Alp will reflect on his thirty years of experiences in dealing with
materials issues.
Grading is based on a term-project, one mid-term and a final exam (30 % each). 10 %
will be given based on class interactions to encourage students to participate as full
partners in the learning process.
