Since it was first published, Quantum Field Theory in a Nutshell has quickly established itself as the most accessible and comprehensive introduction to this profound and deeply fascinating area of theoretical physics. Now in this fully revised and expanded edition, A. Zee covers the latest advances while providing a solid conceptual foundation for students to build on, making this the most up-to-date and modern textbook on quantum field theory available. -/- This expanded edition features several additional chapters, as well as (...) an entirely new section describing recent developments in quantum field theory such as gravitational waves, the helicity spinor formalism, on-shell gluon scattering, recursion relations for amplitudes with complex momenta, and the hidden connection between Yang-Mills theory and Einstein gravity. Zee also provides added exercises, explanations, and examples, as well as detailed appendices, solutions to selected exercises, and suggestions for further reading. (shrink)

Concept of ethics in Ādi-Granth, Sikh canon.

At least for those who uphold the rationality of morality, ethics and practical reason are not two distinct topics: an ethically sound agent is one whose practical reason functions as it should. Take, for instance, the greatest historical figures. Aristotle claimed that no virtue of character can exist without practical wisdom—the excellence of practical, deliberative reason. And Kant thought that the categorical imperative, the ultimate moral principle that governs a good will, was at the same time the fundamental principlof practical (...) reasoning because the will simply ispractical reason. Even before any philosophical theory of the connection between acting well and the exercise of a rational power is in view, our moral practices strongly suggest that there is one. For we take it for granted that, in an important range of cases, when an agent fails to act as she should, something has gone awry with the agent and not just with her acts, and, furthermore, that the agent herself may be held responsible for this. In calling an agent who acts unethically "irrational," we are saying these two things. (shrink)

Upshot: We focus on the following issues: our intentions behind establishing the new Research Through Design conference series; epistemological concerns around “research through design”; and how we might find a balance between openness and specificity for the conference series going forward.

Estudio sistemático sobre la imagen y sus complejas relaciones con el lenguaje verbal, partiendo de una crítica al logocentrismo en su vertiente racionalista -que reduce el conocimiento y el pensamiento al discurso lingüístico- para desembocar en una teoría de la representación. El autor sostiene que la imagen va más allá de la representación al tornarse presencia, basándose en el examen de pensadores clásicos y teóricos actuales que han abordado cuestiones afines. Propone una teoría de la imagen que no se ciñe (...) sólo a lo visual, sino que reconoce las dimensiones no visuales de lo imaginal: "el principal objetivo de este libro es contribuir a la construcción de una filosofía de la imagen. Hoy en día es ya una necesidad urgente contar con un aparato conceptual que nos permita afrontar las distintas modalidades de lo imaginal, que aparecen en ámbitos tan diversos como la intimidad psicológica, la ciencia, la filosofía, la comunicación masiva, la religión, la educación, la propaganda o el arte".

I suppose the most obvious difference in fact between dreams and waking life is the chaotic nature of the former. But this somehow seems to be a mere contingency. Some of our dreams are more contingent than others, and it seems hard to impose any upper limit of coherence on them. Also it is usually after we wake up that they seem incoherent. Similarly many dreams are largely matters of sensation and emotion, mood and atmosphere, with little or no reasoning (...) in them; but this again is contingent, and dreams vary; Professor Broad, 56-57) relates a quite detailed scientific experiment which he carried out in a dream.

A sensible code of right and wrong for public officials everywhere, this book explores what ethics and the public trust mean. It includes sample codes of ethics and examines ways to improve the ethical climate of government. Excerpted and adapted from a longer work, Ethics, Conflicts, and Offices: A Guide for Local Officials, which also covers conflict of interest and office-holding laws in North Carolina.

Work in the field of health has been distorted over the years, with the emergence of new health systems that have made the delivery of services a real business. As a result, the field has lost not only the motivation with which it originated, but also the human quality of providing health care. It is not new to say that exercise of the medical profession is in crisis. The causes of this predicament can be found in policies and health systems (...) that are poorly imitated, poorly administered, mismanaged, and poorly regulated. However, there is no denying the crisis is also due to the loss of the Hippocratic spirit that gave force and vitality to the medical profession from its beginning. Several aspects of work in health and health care, namely, scientific and technical competence (knowledge and knowhow) and human skills (knowing “how to be”), are examined in this chapter, based on a brief look at the patients and the professionals who serve them. The author goes on to discuss three fields of professional activity where these competencies play out: the Hippocratic tradition, social responsibility, and constructive dialogue. In conclusion, and in light of the above, several initiatives and strategies to humanize health services are suggested. They involve example, communication, accompaniment, correction, purpose, and professionalism. (shrink)
