At our conference A. M. Prokhorov and I are assigned the role of Conference Chairs. As far as I understand, the chair of the conference in his obligations is, to a considerable degree, like, say, the King of Belgium or Sweden. The main responsibility of the King is to pronounce the King's Speech. Respectively, the Chair of the Conference is obliged to pronounce the opening speech. The King in his speech usually remembers the glorious periods in the history of the state and emphasizes its greatness to give pride to the subjects' hearts. Also, the chair should recall in his speech some achievements in the work of the conference. The participants of the conference should be assured that they are attending a reliable scientific undertaking rather than some risky adventure like the MMM company. This talk undertakes to accomplish all that.
