© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

Contrary to what might be expected given a religious or other motivation, Pierre Duhem's interest in mediaeval science was the result of his surprise encounter with Jordanus de Nemore while working on Les origines de la statique in the late autumn of 1903. Historical assumptions common among physicists at that time may explain this surprise, which occasioned a frantic search for more mediaeval precursors for Renaissance mechanics. It also raised serious historiographical problems that threatened even his methodological views, until they (...) were resolved in his To save the phenomena of 1908. (shrink)

Is an ethical leader an oxymoron? Society demands and expects greater accountability from organizational leaders. The literature on leadership, especially business leadership, has neglected ethical issues by focusing only on those approaches and strategies that emphasize self-centred, individualistic concerns. How ever, true and effective leadership is one in which the leader's behaviour and the exercise of the leadership influence process are consistent with ethical and moral values. The authors argue that our understanding of leadership is incomplete, if not deformed, if (...) it does not include the three critical dimensions of ethical leadership. (shrink)

Much speculation on the sources of Duhem's historical interests fails to account for the major shifts in these interests: neither his belief in the continuous development of physics nor his Catholicism, when his Church was encouraging the study of generally Aristotelian scholastic thought, led to any interest in mediaeval science before 1904. Equally, his own claim that he was merely testing his views on the nature of physical theory is easily squared only with earlier work with no trace of mediaeval (...) science. Behind this discontinuity lies a major crisis. Though not a positivist, Duhem had based all his work on assumptions acceptable to positivists. One of these, the sterility of the Middle Ages, was refuted by his chance discovery of evidence of genuine mediaeval science in the autumn of 1903, but that left the doctrine of scholastic sterility intact.

It is a safe prediction that, especially now with cultural contacts freely flowing between East and West in both directions, the Hungarian thinker Istvan Bibo will soon be given full accolade as one of the most outstanding political theorists of this century, in stature equal to the �greats� in the entire European tradition of political thought. Bibo's significance far exceeds local, parochial interests. While profoundly original and organically stemming from Hungarian culture, Bibo belongs also to the �West�. If his political (...) thought is to be epitomized in one succinct phrase, it is �the realism of moralism�, or the almost flawless synthesis of a deeply radical, morally infused vision and value-system with the hard-nosed, unsentimental realist-s insight into enduring problems of politics and society. This synthesis is �almost� flawless: in the closing section of this article I will advance a few constructively critical remarks concerning some questionable points in the trajectory of Bibo's thought.
