Observations of the cosmos provide a valuable tool to study the fundamental laws of nature. The future generation of astronomical surveys will provide data for a sizeable fraction of the observable sky. These rich data set should provide the means to answer fundamental questions: what are the laws of physics at high energies in the Early Universe? what is the nature of neutrinos? what is the dark matter? what is the dark energy? why are there baryons at all? ...

. Authors: A.A. Suchkov , V.A. Marakov . Journal: Pis'ma Astron. Zh., 1976, v.2, p.38-385. Metallisity function of globular clusters in the Galaxy is constructed. It is found to have three "humps". This leads to a conclusion that there were three metal enrichment outbursts during the period of globular cluster formation. The constraints on the nature of metal sourses and on the early evolution of Galaxy are considered.
