  4. GCGC-1 Major Topics The properties of the Galactic globular cluster system The stellar content of Galactic globular clusters Relationship between Globulars and other Galactic populations The globular cluster systems of the Magellanic Clouds The globular cluster populations of M31 and M33 Extragalactic globular cluster systems Observational examples of analogs to proto-globular clusters Space-based observations of globular clusters Theories for the formation and evolution of globular clusters The formation and evolution of globular cluster systems within the context of their parent galaxies

  5. Some differences this time: a personal view • bigger and better observational/computational facilities • Keck HIRES, Lick Hamilton, Magellan MIKE, VLT UVES, … • Keck DEIMOS, VLT GIRAFFE & FLAMES, … • dwarf spheroidal data in bulk • multiple globular populations now a reality • n-body simulations are now N-BODY • age differences maybe not as key an issue now? • now RR Lyr and other HB stars studied in detail • detailed interior modeling of late stellar evolution • more realistic “origin” attacks with chemical evolution

  6. GCGC-1 Questionable Quotes Community standards regarding appropriate behavior of globular clusters has changed We did that measurement, but don’t believe it You have to dissect the Horizontal Branch into the horizontal part, and not-so-horizontal part, and the nearly vertical part CNO? Just say NO! I see that you are not convinced, but you can believe me for the moment The dSph galaxies do not photograph well There’s scarcely any object in the universe which hasn’t been nominated as a site of globular cluster formation ASP Conference Series, 1992, vol 48, ed. Graeme Smith & Jean Brodie, page 832
