Mechanical systems represent a new class of devices in which it may soon be
possible to observe macroscopic quantum effects. In addition, they serve as
extremely sensitive detectors for a wide range of phenomena of interest in
mesoscopic physics. A major technical challenge in realizing the full
potential of mechanical systems is controlling their temperature. I will
describe our recent work on understanding the connection between the
thermal fluctuations of a cantilever's microscopic degrees of freedom and
its macroscopic ones (i.e., its center-of-mass motion), which in some
experiments can differ by more than three orders of magnitude. I will also
describe our progress on coupling cantilevers to high-finesse optical
cavities, a promising route to observing quantum effects in mechanical systems.
