The standard von Neumann-Dirac formulation of quantum mechanics is presented as a set of five basic rules. We discuss each rule is discussed in turn paying particular attention to the conceptual history of the theory. Of central importance is the standard interpretation of states (the eigenvalue-eigenstate link) and the dynamical laws of the theory (the random collapse dynamics and the deterministic linear dynamics) and how the interpretation and dynamics work together to predict and explain the results of basic quantum experiments. While the focus is on the behavior of electrons, we also briefly consider how the theory uses the same mathematical formalism to treat other phenomena like the behavior of neutral K mesons and qbits in a quantum computer.

This book charts the transformation of one of the world's great religions during an age marked by world wars, genocide, nationalism, decolonization, and powerful ideological currents, many of them hostile to Christianity. The book traces how Christianity evolved from a religion defined by the culture and politics of Europe to the expanding polycentric and multicultural faith it is today—one whose growing popular support is strongest in sub-Saharan Africa, Latin America, China, and other parts of Asia. The book sheds critical light on themes of central importance for understanding the global contours of modern Christianity, illustrating each one with contrasting case studies, usually taken from different parts of the world. Unlike other books on world Christianity, this one is not a regional survey or chronological narrative, nor does it focus on theology or ecclesiastical institutions. The book provides a history of Christianity as a popular faith experienced and lived by its adherents, telling a compelling and multifaceted story of Christendom's fortunes in Europe, North America, and across the rest of the globe. It demonstrates how Christianity has had less to fear from the onslaughts of secularism than from the readiness of Christians themselves to accommodate their faith to ideologies that privilege racial identity or radical individualism.

Abstract In this paper, we aim at an exercise that is transdisciplinary, involving science and religion, and interdisciplinary, involving disciplines and theories which appeared in the second half of the 20th century (e.g., topology, chaos theory, fractal geometry, non-linear dynamics, all of which can be found in the theory of complex systems). The latter required the reformulation of quantum mechanics theories starting with the beginning of the century, based on the substance-energy-information triangle. We focus on information and we also attempt a transdisciplinary approach to the imaginary from a psychological - physical - mathematical perspective, but the religious perspectives find their place along with the philosophical or even philological vision

Despite the central importance of festival and devotional piety to premodernMuslims, book-length studies in this field have been relatively rare.Katz’s work, The Birth of the Prophet Muhammad, represents a tour-deforceof critical scholarship that advances the field significantly both throughits engagement with textual sources from the formative period to the presentand through its judicious use of theoretical tools to analyze this material. Asits title suggests, the work strives to explore how Muslims have alternativelypromoted and contested the commemoration of the Prophet’s birth atdifferent points in history, with a particular emphasis on how the devotionalistapproach, which was prominent in the pre-modern era, fell out of favoramong Middle Eastern Sunnis in the late twentieth century. Aimed primarilyat specialists in Middle Eastern and Islamic studies, especially scholarsof history, law, and religion, this work is recommended to anyone interestedin the history of Muslim ritual, the history of devotion to the Prophet, andthe interplay between normative and non-normative forms ofMuslim beliefand practice ...

Abstract This article attempts to strip away the Eurocentrism of the Enlightenment, to reconsider how this concept that originated in Europe was transmitted to China. This is thus an attempt to treat the Enlightenment in terms of its global, worldwide significance. Coming from this perspective, the Enlightenment can be viewed as a history of the exchange and interweaving of concepts, a history of translation and quotation, and thus a history of the joint production of knowledge. We must reconsider the dimensions of both time and space in examining the global Enlightenment project. As a concept, the Enlightenment for the most part has been molded by historical actors acting in local circumstances. It is not a concept shaped and brought into being solely from textual sources originating in Europe. As a concept, the Enlightenment enabled historical actors in specific localities to begin to engage in globalized thinking, and to find a place for their individual circumstances within the global setting. This article follows such a line of thought, to discuss the conceptual history of the Enlightenment in China, giving special emphasis to the processes of formation and translation of this concept within the overall flow of modern Chinese history.

The Way

This chapter introduces the theme of the book: scientific understanding. Science is arguably the most successful product of the human desire for understanding. Reflection on the nature of scientific understanding is an important and exciting project for philosophers of science, as well as for scientists and interested laypeople. As a first illustration of this, the chapter sketches an episode from the history of science in which discussions about understanding played a crucial role: the genesis of quantum mechanics in the 1920s, and the heated debates about the intelligibility of this theory and the related question of whether it can provide understanding. This case shows that standards of intelligibility of scientists can vary strongly. Furthermore, the chapter outlines and defends the way in which this study approaches its subject, differing essentially from mainstream philosophical discussions of explanatory understanding. It concludes with an overview of the contents of the book.

Qualitative research does not represent a monolithic, agreed-on approach to research but is a vibrant and contested field with many contradictions and different perspectives. To respect the multivoicedness of qualitative research, this chapter will approach its history in the plural—as a variety of histories. The chapter will work polyvocally and focus on six histories of qualitative research, which are sometimes overlapping, sometimes in conflict, and sometimes even incommensurable. They can be considered articulations of different discourses about the history of the field, which compete for researchers’ attention. The six histories are: (a) the conceptual history of qualitative research, (b) the internal history of qualitative research, (c) the marginalizing history of qualitative research, (d) the repressed history of qualitative research, (e) the social history of qualitative research, and (f) the technological history of qualitative research.
