Thomas Kuhn’s The Structure of Scientific Revolutions offers an insightful and engaging theory of science that speaks to scholars across many disciplines. Though initially widely misunderstood, it had a profound impact on the way intellectuals and educated laypeople thought about science. K. Brad Wray traces the influences on Kuhn as he wrote Structure, including his ‘Aristotle epiphany’, his interactions, and his studies of the history of chemistry. Wray then considers the impact of Structure on the social sciences, on the history (...) of science, and on the philosophy of science, where the problem of theory change has set the terms of contemporary realism/anti-realism debates. He examines Kuhn’s frustrations with the Strong Programme sociologists’ appropriations of his views, and debunks several popular claims about what influenced Kuhn as he wrote Structure. His book is a rich and comprehensive assessment of one of the most influential works in the modern sciences. (shrink)

Because the evolution of speech production is beyond our expertise (and perhaps beyond everyone's expertise) we restrict our comments to areas in which data actually exist. We provide articulatory evidence consistent with the claims made about syllable structure in adult speech and infant babbling, but we also voice some disagreement about speech errors and the typing data.

Dieses Werk ist ein Reproduktion des Originals, das vor 1903 veröffentlicht wurde. Rabbi Nathan war ein wichtiger jüdischer Gelehrter und Schriftsteller. In 'Rabbi Nathans System der Ethik und Moral' beschreibt er seine Ansichten und Lehren über Ethik und Moral. Das Werk ist ein wichtiger Beitrag zur Entwicklung der jüdischen Moraltheologie und bietet einen Einblick in die vielfältigen und tiefgründigen Debatten, die in der jüdischen Welt seit Jahrhunderten geführt werden. This work has been selected by scholars as being culturally important, and (...) is part of the knowledge base of civilization as we know it.

Level statistics and nodal point distribution in a rectangular semiconductor quantum dot are studied for different degrees of spin-orbit coupling. The chaotic features occurring from the spin-orbit coupling have no classical counterpart. Using experimental values for GaSb/InAs/GaSb semiconductor quantum wells we find that level repulsion can lead to the semi-Poisson distribution for nearest level separations. Nodal lines and nodal points are also investigated. Comparison is made with nodal point distributions for fully chaotic states.

Equality is a concept that is often used in health care discussions about the allocation of resources and the design of health care systems. In secular discussions and debates the concept of equality is highly controverted and can take on many different specifications. One might think that Christians hold a common understanding of equality. A more careful study, though, makes it quite clear that equality is just as controversial among different Christian communities as it is in the secular world.

This essay delineates points of agreement and disagreement between Plato and Nietzsche with respect to the original Heraclitean argument that the underlying dynamic connective structure of the whole is ‘strife’. Also discussed is the issue of how each philosopher understands life itself, as a general process, to be related to the wider processive whole. The paper analyses how the Heraclitean understanding of the natural whole influences each philosopher's interpretation of the political structures of man. The analysis attempts to demonstrate why (...) for Nietzsche, on one hand, the value forms of the traditional polis are more in accord with human nature and nature in toto than is philosophy and why for Plato, on the other hand, when the value forms of the polis are superseded by those of philosophy it is a natural process rather than contrary to nature.

Open peer commentary on the article “Examining the Role of Re-Presentation in Mathematical Problem Solving: An Application of Ernst von Glasersfeld’s Conceptual Analysis” by Victor V. Cifarelli & Volkan Sevim. Upshot: The value of Cifarelli & Sevim’s target article lies in the analysis of how reflective abstraction contributes to the description of mathematical learning through problem solving. The additional value of the article lies in its emphasis of some aspects of the learning process that goes beyond radical constructivist learning theory. (...) I will look for common ground between the humanist philosophy of mathematics and radical constructivism. By doing so, I want to stress two converging elements: (i) the move away from traditionalist ontological positions and (ii) the central role of the students’ activity in the learning process.

Based on the writings of D.S. Kothari; includes his brief biographical sketch and review of his four books.

Open peer commentary on the article “Designing Constructionist E-Books: New Mediations for Creative Mathematical Thinking?” by Chronis Kynigos. Upshot: Chronis Kynigos’s article invites us to explore how to make familiar objects for learning — namely, books — more constructionist. In my response, I ask questions about the affordances and potential limitations of books as central objects, particularly about the role of the learner in relation to the objects.
