  At the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National
Laboratory, heavy nuclei are collided at high energies to create matter that is
hot enough and dense enough to dissolve hadrons into a quark-gluon-plasma
(QGP). In this lecture, dedicated to the memory of Aditya Sambamurti, I present
an introduction to heavy-ion collisions and highlights from the first decade of
RHIC results.
