Astroparticle physics - A Personal Outlook

Abstract

At the request of the organizers, this talk surveys some of the hot topics discussed at this meeting, giving my {\it subjective views} on them. Subjects covered include the present age and Hubble expansion rate of the Universe - {\it inflation theorists need not yet abandon $\Omega =1$}, theories of structure formation in the light of COBE and other data - {\it my favourite is a flat spectrum of initial perturbations subsequently amplified by mixed hot and cold dark matter}, neutrino masses and oscillations - {\it the only experimental indication I take seriously at the moment is the persistent solar neutrino deficit}, the lightest supersymmetric particle - {\it which may behave differently if conventional assumptions are relaxed}, and the axion - {\it much of the window between limits from SN 1987a and cosmology will be explored in an ongoing experiment}. Finally, I present a chronology of some possible interesting future experiments.
