Broken Symmetry

This book contains selected papers of Prof Nambu who is one of the most original and outstanding particle theorists of our time. This volume consists of about 40 papers which made fundamental contributions to our understanding of particle physics during the last few decades. The unpublished lecture note on string theory (1969) and the first paper on spontaneous symmetry breaking (1961) are retyped and included. The book also contains a memoir of Prof Nambu on his research career.

These, together with the selected research papers, provide an excellent scientific biography of Nambu and of the Japanese physics tradition, which he describes in several places … it is in the less formal presentations that the motivation for Nambu's ideas, as well as his charming modesty, become evident and make reading this collection the pleasure that it is.” Physics Today “In the citation of Nobel physics prize committee, Nambu's unpublished paper presented at Mid West Conference at Purdue University in 1960 is referred to as the original article on spontaneously broken symmetry. This is the paper which we have decided to include in the volume ‘Broken Symmetry’ because of its historical importance. The paper would have been inaccessible and may not have been noticed by the general public if it were not retyped and included in the volume.” T Eguchi and K Nishijima Editors
