The book is a collection of new materials on some representative non-technical writings of Professor Abdus Salam. The essays touch on many different themes, in particular the social and economic dimensions of science. Difficulties faced by scientists in developing countries and their solutions are also given some insightful analysis.Topic of particular interest is Professor Salam's view on the development and the international nature of science. His insistence that a scientific thought and its creation is the common and shared heritage of mankind which deserves much thought. There are also interesting accounts of Professor Salam himself and of the International Centre for Theoretical Physics at Trieste, Italy.
