We evoke some poetical aspects of a new kind of logical truth (an inner quantum truth) embodying both physical and mathematical concepts, which can be viewed at the same time as a constructive mathematical object, as well as a pure platonic idea.

And while I have sought to shew the naturalist how a few mathematical concepts and dynamical principles may help and guide him, I have tried to shew the mathematician a field for his labour—a field which few have entered and no man explored. Here may be found homely problems, such as often tax the highest skill of the mathematician, and reward his ingenuity all the more for their trivial associ...

A guide for those who wish to understand and to work with the hydro-geochemical equilibrium code CHESS together with introductory aspects of thermodynamic principles and surface com-plexation chemistry. The CHESS model was initially written at the Ecole des Mines de Paris within the framework of the R&D program on Management and Storage of Radioactive Waste

The five papers that comprise this special issue entitled ‘‘The conceptual change approach to mathematics learning and teaching,’’ attempt to demonstrate that the conceptual change approach can be a fruitful component of a theory of mathematical learning and instruction. Some of them focus on issues of learning i.e., on presenting evidence that the conceptual change approach provides a powerful...

Actual–desired discrepancies in people’s self-concepts represent structural incongruities in their self-representations that can lead people to experience subjective conflict. Theory and research suggest that structural incongruities predict susceptibility to subtle influences like priming and conditioning. Although typically examined for their motivational properties, we hypothesized that beca...

We investigate the relation between two quantitative measures characterizing short term memory in input driven dynamical systems, namely the short term memory capacity (MC) [2] and the Fisher memory curve (FMC) [1]. We show that under some assumptions, the two quantities can be interpreted as squared ‘Mahalanobis’ norms of images of the input vector under the system’s dynamics and that even tho...

Der folgende Artikel gibt einen Kurzüberblick über ein Promotionsvorhaben im Bereich der Quantitativen Modellierung. In der Dissertation soll die Modellierungsmethodik FMC-QE (Fundamental Modeling Concepts for Quantitative Evaluation) beschrieben werden. FMC-QE basiert auf der Modellierungssprache FMC sowie den Modellierungsund Berechnungsmethoden der Warteschlangentheorie und der Zeitbehaftete...

Teaching mathematics in a high school and in a community college in the New York City, I have noticed that students grasp mathematical concepts more quickly and understand them better when a connection between the concept and the world of business is established. Students were visibly more interested and involved when business applications were presented first, laying the groundwork for technol...

Fixed–mobile convergence (FMC) is a radical innovation for telecommunication companies because it requires them to move into unknown territories that are beyond traditional business lines and underlying technologies. In the meantime, understanding what types of telecommunication companies are better at doing business through the early adoption of FMC has become increasingly important in the con...

The question of the self has intrigued philosophers and psychologists for a long time. More recently, distinct concepts of self have also been suggested in neuroscience. However, the exact relationship between these concepts and neural processing across different brain regions remains unclear. This article reviews neuroimaging studies comparing neural correlates during processing of stimuli rel...
