The basic idea and of differential
geometry is to say something about the geometry of an object by moving
a little bit on this object - for instance moving along a curve or on a
surface. Turning this approach into a questions it reads: what kind of
information can I get about my curve or my surface if I move a little
bit on them? It turns out that there is indeed a lot one can learn.
For a curve, one gets tangent directions, curvature and other geometric
information in this way. For a surface, there are 2-d generalizations
of these concepts.
striking fact is that knowing this information everywhere allows you
for instance to discover that the earth is not flat. Furthermore it
allows to explain why there cannot be any maps of the earth which give
the right distances and angles at the same time. These types of
considerations are also the basis for the theory of general relativity.
In this course, we will treat curves and surfaces from the above
perspectives which lead us to the results discussed above. We will
provide a classical treatment, but the results and concepts have
applications in discretized versions for computer imaging and methods
of finite elements.

**The basic idea is that you write down the equations for a curve, give
its geometric properties, relate them to the equation and maybe give
history and/or applications.
Check the famous curve index for a starting point. You can also pick an
example from the book or come up with something on your own.
