Cambridge University Press, 1990. Blue cloth, 143 pp. Fine in fine jacket. "This is an expanded version of the third Dirac Memorial Lecture, given in 1988 by the Nobel Laureate Abdus Salam. Salams lecture presents an overview of the developments in modern particle physics from its inception at the turn of the century to the present theories seeking to unify all the fundamental forces. In addition, two previously unpublished lectures by Paul Dirac, and Werner Heisenberg are included. These lectures provide a fascinating insight into their approach to research and the developments in particle physics at that time. Nonspecialists, undergraduates and researchers will find this a fascinating book. It contains a clear introduction to the major themes of particle physics and cosmology by one of the most distinguished contemporary physicists."; 12mo 0521371406

London: Methuen, 1925. Octavo, light blue cloth. pp [2], (xiv), 203 pp + 7 plates and one folding table. 39 diagrams in text, Index. Band of yellowing to inner margins of free endpaper (from binding materials), short shallow bruise to upper inner corner of rear cover; spine very lightly darkened; else fine and fresh, no owner marks. Cream dust jacket lightly yellowed to spine and flap folds; tiny chips to spine ends; short shallow chip to upper inner corner of rear panel; else fine, flap price intact. "This book is intended to assist those who have not specialised in this branch of science, to make themselves familiar with modern X-ray physics. To this end a somewhat new treatment has been adopted. A well-illustrated chapter on X-ray spectographs increases the value of the work." - jacket. Maurice de Broglie was the elder brother of Louis de Broglie. They sometimes collaborated and co-authored a paper in 1921. Louis built on their shared research, but he was a theoretical physicist whereas Maurice was an experimental physicist. Louis was the first to postulate the wave-partical duality of matter, in 1924, and he won a Nobel Prize in 1929. Maurice did important work on in the study of X-ray diffraction and spectroscopy (he invented X-ray spectroscopy). In 1942 he assumed the Chair of Physics in the Collège de France and was elected to the Royal Society in London in 1940, having received their Hughes Medal in 1928 for his work on X-ray spectra. A superior copy of an important physics book.
