       Abstract 

      We live in a hot Universe. More than 80% of all normal matter is at temperatures above a half million degrees, where it can readily be observed only in X rays. Study of hot gas is needed to locate the "missing baryons" and verify standard theories of structure formation, to understand feedback regulation of star formation, and to understand metal transport in the intergalactic medium, from clusters and individual galaxies, and within our Galaxy. I will discuss the instrumental difficulties of making these observations, and progress being made in overcoming them.
