In this talk we will present a series of results and open problems emerging from the study of infinite global fields. We will give a survey of the asymptotic properties of the Brauer-Siegel and Euler-Kronecker invariants in the classical situation of number fields and function fields as well as in certain higher dimensional cases. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

... A clear understanding of the 3D-structure of the nearby Virgo cluster and the knowledge of a precise cluster distance are key issues for many astronomical fields. ... From the scientific point of view the best choice for a study of the distance and 3D-structure of the Virgo cluster are the low-surface brightness dwarf elliptical (dE) galaxies. ... Secondly, the dwarf ellipticals are the only galaxies which exist in large numbers in the Virgo cluster core (Binggeli et al. ...
