    "abstract": "In this paper we present the two-state vector formalism of quantum mechanics.\nIt is a time-symmetrized approach to standard quantum theory particularly\nhelpful for the analysis of experiments performed on pre- and post-selected\nensembles. Several peculiar effects which naturally arise in this approach are\nconsidered. In particular, the concept of ``weak measurements\u0027\u0027 (standard\nmeasurements with weakening of the interaction) is discussed in depth revealing\na very unusual but consistent picture. Also, a design of a gedanken experiment\nwhich implements a kind of quantum ``time machine\u0027\u0027 is described. The issue of\ntime-symmetry in the context of the two-state vector formalism is clarified.",
