The Course, organized by the Sezione di Torino of the Istituto Nazionale di Fisica Nucleare (I.N.F.N.), was attended by 85 participants. The main goal of the School, following the spirit of the previous schools, was to present to young physicists some actual open problems on various fields of fundamental modem physics. We tried to link the topics belonging to the different fields to a common ground: the coherence in quantum field theories (QED and QCD). The book contains most of the lectures given at the School in the following fields: - Coherent phenomena - Subnuclear physics -Nuclear physics - Experimental techniques and particle accelerators Some papers reflect the tutorial level of the Lecture given at the Course. We are strongly indebted to Prof. N. Cabibbo, President of the I.N.F.N. for financial support to the School. Acknowledgements are due to Miss L. Bonafini and Mrs. C. Nuncibello for their precious support in organizing the School. Mr. S. Cavallo is acknowledged for his valuable technical assistance. Thanks are due to the Folgaria Tourism Agency and to the Folgaria Meeting Committee, in particular to Dr. G. Dorigati, Mr. F. Demozzi and Miss A. Ciech for their assistance in the organization. T.
