# Symmetry, Structure and Tensor Properties of Materials | MITx on edX | About Course Video

When you hear the word
crystals, what do you think? Do high rise buildings,
jet engine turbines, and computer chips come to mind? Crystals are all around
us, modern civilization depends on them. What makes something a crystal? It doesn’t have to be
transparent or sparkle like a gemstone. Instead, the arrangement of
atoms on the atomic scale follow specific
mathematical rules. Like the symmetry of
the natural world, the atomic world of
crystals has structure. The structure and
symmetry of materials has a profound effect
on physical properties. By looking only at the
material structure, we could learn about its ability
to deform, conduct electricity or heat, and many other things. Hi, I’m Gene Fitzgerald, and I’m
a professor of material science and engineering here at MIT. And I’m Richard Taylor. We will be your instructors
in 3.072X Symmetry, Structure, and Tensor Properties
of Materials. Together, we will
explore the structure of crystalline materials. To get the most
out of this class, you should have some background
in physics and chemistry, and you should be
comfortable with trigonometry and some basic matrix algebra. By the end of 3.072X you
will understand the lattices, point groups, and space groups
that are used to classify crystalline materials. And you’ll be able to
use tensors to represent the properties of
these materials. You will also gain an
appreciation of the role that crystal symmetries
play in determining the properties of materials. And through class projects, you
will explore these structure property relationships
in the materials that you find most interesting. We hope that you will join
us as we explore the world of crystalline
materials in 3.072X.
