  Star clusters are evolving n-body systems. We discuss the early dynamics of
star clusters, the process of primordial mass segregation and clustering
observed in certain young clusters. We discuss how the dynamics coupled with
stellar evolution of a cluster define the radial profile, mass function of and
disruption the cluster and compare these parameters with some known clusters.
As a member of the Thirty Meter Telescope (TMT), International Science Driven
Team (ISDT), I shall use these details to help define the science case,
requirements and the expected precision in answering possible questions about
the evolution of star clusters in terms of astrometry and high resolution
spectroscopy. I shall also report on some of the resolutions made at the recent
TMT-Forum held in Mysore, India.
