The year 2007 marked not only the centenary of Imperial College London but also the 50th anniversary of the late Nobel Laureate Professor Abdus Salam's arrival at the College. Accordingly, a conference entitled “Salam + 50” organized by the Theoretical Physics Group was held at Imperial College on 7 July 2007.Many distinguished guests attended and paid their respects to the great man. Their contributions recorded in these proceedings are divided into three sections, designed to reflect the three dimensions of Salam's character: 1) Salam the Scientist, 2) Salam the Humanitarian, and 3) Salam the Man.

Superstring theory and its successor, M-theory, hold promises of a deeper understanding of the Standard Model of particle physics, the unification of the four fundamental forces, the quantum theory of gravity, the mysteries of quantum black holes, Big Bang cosmology and, ultimately, their complete synthesis in a final theory of physics.This volume records the proceedings of the major annual international conference on the subject, “Strings 2000”, which involved 42 talks by the world's leading experts on string theory and M-theory. It will be of interest not only to researchers in the field but also to all those who wish to keep abreast of the latest developments and breakthroughs in this exciting area of theoretical physics.

Steven Weinberg (1933-2021) was a theoretical physicist and Nobel laureate who contributed tremendously to particle physics. Until his death, Weinberg was regarded by many as the greatest living scientist. His most well-known work was the formulation of electroweak theory for which he earned the 1979 Nobel Prize with Sheldon Glashow and Abdus Salam, but his research spanned many other fields. Examples include effective Lagrangians, quantum chromodynamics, supersymmetry, quantum gravity, and cosmology.Weinberg's publications were renowned not only for their profundity and originality but also for their devastating logic and clarity. This volume brings together 37 of his most significant papers, together with commentaries, providing today's physicists with easy access to these seminal papers. More than just a collection, this selection by editor Michael Duff places each article into a comprehensive overview, providing the reader with the scientific and historical context of Weinberg's finest papers.

"This book presents a timely set of academic and intellectual views on Salam’s scientific passion, contribution and personality, and will be of great interest to academics in the fields of particle physics, high energy physics and scientific history of the developing world."Contemporary PhysicsIn honor of one of the most prolific and exciting scientists of the second half of the last century, a memorial meeting was organized by the Institute of Advanced Studies at Nanyang Technological University for Professor Abdus Salam's 90th Birthday in January 2016.Salam believed that "scientific thought is the common heritage of all mankind" and that the developing world should play its part, not merely by importing technology but by being the arbiter of its own scientific destiny. That belief saw him rise from humble beginnings in a village in Pakistan to become one of the world's most original and influential particle physicists, culminating in the 1979 Nobel Prize (shared with Glashow and Weinberg) for contributions to electroweak unification, which forms an integral part of the Standard Model.The book collected the papers presented at this memorable event which saw many distinguished scientists participating as speakers to reflect on Prof Salam's great passion for the science and achievements.

This is the first of a new series of conferences on High Energy Physics to be held at the ICTP on Trieste. The aim of the present Conference is to cover various aspects of physics in 2+1 dimensions, especially (super)membrane theories, and to provide a platform for a discussion of the up-to-date status of the field. There will also be introductory lectures which should be useful, especially to those who wish to begin research in this subject.

Some topics covered during the workshop include String Theory, Conformal Field Theory, Physics in 2+1 Dimensions, String Phenomenology and Quantum Cosmology.

The success of the standard model in explaining low energy (≈ 100GeV) physics within the framework of spontaneously broken Yang-Mills theory has given physicists the hope that the Einstein dream of a unified theory of fundamental interactions might be achieved using geometrical methods of local symmetry principles supplemented by consistency requirements such as renormalization, unitarity and, most crucially, compatibility with present low energy data.Merging these principles with the quantum-mechanical notions of spin and statistics led physicists further to develop new theories in the last fifteen years for which the gauge symmetry principle is extended to incorporate supersymmetry and relativistic extended objects - the most famous example being superstrings propagating in curved space-time and having supergravity as their effective field theory.The proceedings represent the latest highlights in the field reported on by active researchers working in this particular area in addition to discussions on future perspectives.

These proceedings form an analysis of the nonperturbative aspects of strings, branes and supersymmetry. Issues addressed include supermembranes and the Matrix theory; non-supersymmetric strings; superembeddings; aspects of the M5-brane; and domain walls and the universe.

Two theories revolutionized the 20th century view of space and time: Einstein's general theory of relativity and quantum mechanics. Their union has given rise to elementary particle theories with extra spacetime dimensions, the inflationary model of big bang cosmology, the hypothesis of dark matter in the universe, the discovery of radiation from quantum black holes, and the fuzzy spacetime geometry of superstrings and M-theory. In this important book, experts present the latest developments in cosmology, theoretical physics and mathematics, as well as share their thoughts on the future of spacetime physics.
