It is a great honour for me to welcome you at the beginning of our conference. The large number of government representatives, and authorities shows that the object and intentions of academic research have become the deep concern of society at large. So I welcome respectfully the representative of the Minister of Education thanking him, at the same time, for the subvention without which these Hochschulwochen could not have taken place. Unfortunately Prof. Budini who is the representative of the director-general of the International Atomic Energy Agency, Vienna, and director of the International School of Theoretical Physics at Trieste cabled yesterday that he became sick and cannot attend our conference. We have to thank the organisation he represents for cooperation and financial support. I hope Prof. Budini’S condition is not serious and that he will soon be restored to good health.
