    ABSTRACT: We present a written version of four lectures given at the NATO Advanced Study Institute on "CD Perspectives on Hot and Dense Matter"in Cargese, Corsica during August, 2001. Over the last year the first exciting results from the Relativistic Heavy Ion Collider (RHIC) and the four experiments BRAHMS, PHENIX, PHOBOS, and STAR have been presented. In these lectures we review the state of RHIC and the experiments and the most exciting current results from Run I which took place in 2000. A complete review is not possible yet with many key results still preliminary or to be measured in Run II, which is currently underway, and thus the emphasis will be on the approach experimentalists have taken to address the fundamental physics issues of the field. We have not attempted to update the RHIC results for this proceedings, but rather present it as a snapshot of what was discussed in the workshop. The field is developing very quickly, and benefits greatly from contact and discussions between the different approaches of experimentalists and theorists.

    ABSTRACT: Strangeness production has long been proposed as a diagnostic tool for understanding the dynamics of relativistic heavy ion collisions. In this presentation we review the traditional picture of strangeness enhancement as a signature for quark-gluon plasma formation. We then review, in order, some experimental data on strange particle production in $e^{+}e^{-}$, $pp$, $p\bar{p}$, proton-nucleus and nucleus-nucleus collisions. This is not a comprehensive review, but rather an emphasis of a few significant points. Any clear interpretation of strange particle yields measured in heavy ion reactions is impossible without a physical understanding of the production mechanisms in elementary particle collisions.

Over the last year the first exciting results from the Relativistic Heavy Ion Collider (RHIC) and the four experiments BRAHMS, PHENIX, PHOBOS, and STAR have been pre-sented. In these lectures we review the state of RHIC and the experiments and the most exciting current results from Run I which took place in 2000. A complete review is not possible yet with many key results still preliminary or to be measured in Run II, which is currently underway, and thus the emphasis will be on the approach experimentalists have taken to address the fundamental physics issues of the field.
