Even in this age of information explosion, Seminars and Symposia have an importance of their own, particularly in countries which are scientifically and geographically remote from active centres of learning. Our scientists suffer this isolation very acutely; the Cow~ission recognises this problem and has endeavoured to solve it through organisation of meetings and conferences in Pakistan to which international specialists in different fields are invited to share their experience with colleagues in Pakistan. We find that the personal encounter and human touch still remain one of the most effective methods of transferring and sharing scientific knowledge. The International Summer College at Nathiagali held in August, 1976, also grew out of our need to communicate with each other and to identify promising areas of development relevant to the needs of a developing country. In the implementation of this idea, the Pakis­ tan Atomic Energy Commission received support from the International Centre for Theoretical Physics, Trieste and from the Swedish Inter­ national Development Authority which is gratefully acknowledged.

These proceedings cover the lectures delivered at the Second International Summer College on Physics and Contemporary Needs held from June 20 - July 7, 1977 at Nathiagali, one of the scenic hill resorts in the northern part of Pakistan. The college was organised by the Pakistan Atomic Energy Commission (PAEC) and co-sponsored by the International Centre for Theoretical Physics, Trieste (ICTP). It also received a financial grant by the University Grants Commission for the participation of physicists from various universities of Pakistan. The college was attended by 13 lecturers, 7 invited semi­ nar speakers and 134 participants from 26 countries and consisted of 15 concentrated days of lectures, seminars-and informal discu­ ssions. These proceedings contain only regular lectures delivered there but. the seminars which were held are listed in the Appendix. The theme of the college covered two important aspects of science in general and physics in particular: first to provide to the participants from developing countries some of the excitement of what is happening at the frontiers of physics; secondly as the name of the college emphasises it was to encourage the physicists from developing countries to interest themselves in and to use their knowledge and methodology of research for attacking some of the problems faced by their respective countries. The lectures delivered at the college covered a wide spectrum of physics and indicated similarity of methodology used in various branches of physics as well as practical applications of some of the topics discussed.

These proceedings cover the lectures delivered at the Third International Summer College on Physics and Contemporary Needs held from June 17 - July 5, 1978 at Nathiagali, one of the scenic hill resorts in the northern part of Pakistan. The college was organized by The Pakistan Atomic Energy Commission (PAEC) and co-sponsored by the International Centre for Theoretical Physics, Trieste (ICTP). It also received a financial grant by the University Grants Commission for the participation of physicists from various universities of Pakistan. The college was attended by 14 lecturers, 2 invited seminar speakers and 156 participants from 23 countries and consisted of 15 concen­ trated days of lectures, seminars and informal discussions. These proceedings contain only regular lectures delivered there, but the seminars which were held there are listed in the Appendix. This year the college put special emphasis on energy, parti­ cularly on nuclear energy and its role in the context of energy sys­ tems. However the lectures delivered at the college also covered a wide spectrum of physics. The lectures gave an overview of various topics covered at the college and emphasized the inter-disciplinary aspects of physics. Some of the lecturers also indicated the areas where research in developing countries with limited facilities could be carried out. The college had a definite objective of encouraging the physicists, part~cularly those working at the universities, to apply their knowledge of physics and methodology of research to the needs of modern society.

These proceedings cover the lectures delivered at the Fourth International Summer College on Physics and Contemporary Needs held from June 16 - July 4, 1979 at Nathiagali, one of the scenic hill resorts in the northern part of Pakistan. The college was organised by Pakistan Atomic Energy Commission (PAEC) and co-sponsored by the International Centre for Theoretical Physics, Trieste (ICTP), Italy. It also received a financial grant from the University Grants Commi­ ssion for the participation of physicists from various universities of Pakistan. The college was attended by 16 lecturers and invited seminar speakers. It was attended by 186 participants from 28 coun­ tries and consisted of 15 concentrated days of lectures, seminars and informal discussions. These proceedings contain only regular lectures delivered at Nathiagali but the seminars held there are listed in the Appendix. This year the college put special emphasis on various energy systems, including their long term implications, and computer software. However, the lectures delivered at the college also covered a wide spectrum of physics. The series of the colleges of which the present college is the fourth one are an attempt to remove the barrier of isolation for the physicists working in developing coun­ tries, far removed from active centres of research. Thus these colleges could help to fill the important gap in communication between the physicists of developing and advanced countries.

Most of the progress made in particle physics during the last two decades has to led to the formulation of the so called “Standard Model” of elementary particles and its quantitative experimental test. The book deals with this progress but includes chapters which provide the necessary background material to modern particle physics.Particle physics forms an essential part of physics curriculum. This is a textbook but will also be useful for people working in this field and for nuclear physicists, particularly those who work on topics concerning interface between nuclear and particle physics. The book is designed for a semester course for senior undergraduates and a semester course for graduate students. Formal quantum field theory is not used; a knowledge of non-relativistic quantum mechanics is required for some parts of the book; but for the remaining parts the familiarity with the Dirac equation is essential. However, some of these topics are included in the appendix.

This is a selection from over 250 papers published by Abdus Salam. Professor Salam has been Professor of Theoretical Physics at Imperial College, London and Director of the International Centre for Theoretical Physics in Trieste, for which he was largely responsible for creating. He is one of the most distinguished theoretical physicists of his generation and won the Nobel Prize for Physics in 1979 for his work on the unification of electromagnetic and weak interactions. He is well known for his deep interest in the development of scientific research in the third world (to which ICTP is devoted) and has taken a leading part in setting up the Third World Academy. His research work has ranged widely over quantum field theory and all aspects of the theory of elementary particles and more recently into other fields, including high-temperature superconductivity and theoretical biology. The papers selected represent a cross section of his work covering the entire period of 50 years from his student days to the present.

Formal quantum field theory is not used. A knowledge of nonrelativistic quantum mechanics is required for some parts of the book, but for the remaining parts familiarity with the Dirac equation and Feynman rules is essential. However, some of these topics are included in an appendix.In this second edition, many chapters (e.g. on electroweak unification) have been revised to bring them up to date. In particular, the chapters on neutrino physics, particle mixing and CP violation, and weak decays of heavy flavors have been rewritten incorporating new material and new data. The heavy quark effective theory has been included.
