The text of the 1986 Dirac Memorial Lectures, long available as a slim hardback, is now available in paperback. Feynman dismantles field theory to find the real reason for the existence of antiparticles, then puts the theory together again. Weinberg’s compelling prose “Towards the final laws of physics” examines how quantum physics can be reconciled with gravity. Over a decade later, the messages in these lectures remain fresh.
