After presenting some (personal) history of Macaulay/Macaulay2, we will use Macaulay2 to investigate a couple of problems, the first one being: what kinds of invariants (e.g. regularity, graded Betti numbers) are possible for ideals generated by small numbers of quadrics. This is a good problem to see some of what can be done with Macaulay2 and how to use the system effectively: the invariants are easy to describe, compute, and their investigation will allow us to see a number of features of the Macaulay2 programming language. We will not assume any previous experience with Macaulay2. We will end with a preview of some upcoming new features.
