Recurrences have been central to the study of dynamical
systems ever since the inception of the subject. Periodic solutions
make the notion of recurrences exact. The Lorenz attractor is the best
known example of a strange attractor and we will describe a method to
find periodic solutions that lie on it. Additionally, we will consider
a turbulent channel flow and describe the computation of time periodic
solutions using nearly $300,000$ degrees of freedom to represent the
velocity field.
