The text of the treatise “The Propositional Logic of Boethius” was finished in 1939. Prof. Jan Lukasiewicz wished at that time to issue it in the second volume of “Collectanea Logica”; as a result of political events, he was not able to carry out his plan. In 1938, I published an article in “Erkenntnis” entitled “AUS- sagenlogik im Mittelalter”; this article included the contents of a paper which I read to the International Congress for the Unity of Science in Cambridge, (...) England, in 1938 (Cf. Erkenntnis, vol. 7, pp. 160-168). The subject matter of this paper touched upon that of the above-mentioned treatise. Recently an article of Mr. Rend van den Driessche, “Sur le ‘de syllogismo hypothetico’ de Boece”, was published in the journal “methodos” (vol. I, no. 3). Mr. van den Driessche referred in this article to the article on propositional logic in the middle ages, which had appeared in “Erkenntnis”. This reminded me of my yet-unpublished treatise on the propositional logic of Boethius. (shrink)

This article describes a descriptive-qualitative method for analyzing and reviewing several textbooks for high school as samples commonly used by teachers and students in their teaching–learning to reveal possible misconceptions. This study focused on the subjects of quantum numbers and electronic configuration. From the advanced literature review to analyze the samples the occurrence of various misconceptions was noted. All textbooks described correctly the four symbols of quantum numbers, but none correlates correctly the magnetic-angular quantum number to the Cartesian labeled orbitals. (...) All textbooks consider mistakenly the meaning of aufbau as the building-up energy of orbitals by following (n + ℓ, n) rules on describing the electronic configuration for all atoms. Only one textbook states that the electronic configuration of transition metal atoms (3d series) can be described in the following order of shell (n), thus giving rise to two types of electronic configurations, [Ar] 3d 4s (Type I) beside [Ar] 4s 3d (Type II), leading further misconception. All textbooks described favorably an unpaired electron of ms = + ½ due to the specific agreement, which is a potential misconception in applying Hund’s rule. In drawing the diagram boxes of orbitals, they are arranged in increasing or decreasing the numeric mℓ, due to the specific agreement, and again leading to a potential misconception on describing the quantum number of electrons issued. Three textbooks introduced the terms of the last and the xth electron associated with the quantum numbers, leading to serious further misconceptions. No books stated that the ordering energy of the (n + ℓ, n) rule is true only for the first twenty atoms. (shrink)

It has often been claimed that without drastic conceptual innovations a genuine explanation of quantum interference effects and quantum randomness is impossible. This book concerns Bohmian mechanics, a simple particle theory that is a counterexample to such claims. The gentle introduction and other contributions collected here show how the phenomena of non-relativistic quantum mechanics, from Heisenberg's uncertainty principle to non-commuting observables, emerge from the Bohmian motion of particles, the natural particle motion associated with Schrödinger's equation. This book will be of (...) value to all students and researchers in physics with an interest in the meaning of quantum theory as well as to philosophers of science. (shrink)

The Commentary on the Vienna Convention on the Law of Treaties provides an in-depth article-by-article analysis of all of the Vienna Convention's provisions. Each provision's analysis consists of (I) Purpose and Function of the Article, (II) Historical Background with Negotiating History, (III) Elements of the Article and finally (IV) Treaties of International Organizations. In short, the present Commentary contains a comprehensive legal analysis of all aspects of the international law of treaties. Furthermore, where the law of treaties reaches into other (...) fields of international law, e.g. the law of state responsibility, the relevant interfaces are discussed and contextualized. With its focus on international practice, the Commentary is an invaluable reference for both academia and practitioners of international law. (shrink)

Im Zentrum des Buchs steht Fichtes Subjektivitätsmodell in den ersten beiden Versionen der Wissenschaftslehre, der Grundlage der gesamten Wissenschaftslehre und der Wissenschaftslehre nova methodo. Beleuchtet wird die Konzeption von Subjektivität als Prinzip von Fichtes System, als transzendentaler Grund unseres Wirklichkeitsbezugs im Denken und Handeln. Erst über eine Aufklärung der Struktur von Subjektivität kann unser Bezug auf eine objektive Wirklichkeit verständlich gemacht werden. Fichtes Modell wird als produktive Reflexion interpretiert, insofern es eine Begründung von Erfahrung in der Selbstbestimmung des Ichs leisten (...) will. Hierbei wird die Genese des Modells vor dem Hintergrund seiner Systemkonzeption und seiner Auseinandersetzung mit dem Skeptizismus analysiert. Schließlich wird dieses auch in Bezug auf die Modelle Kants und Hegels verortet. The book explores Fichte's notion of subjectivity in his early science of knowledge (Wissenschaftslehre). It examines the model of subjectivity which underlies Fichte's system, and which serves as the transcendental fundament of our theoretical and practical relation to reality. Fichte's notion of subjectivity is interpreted as productive reflection, grounding human experience in the self-determination of the self-positing subject. (shrink)

Threatened Knowledge discusses the practices of knowing, not-knowing, and not wanting to know from the middle ages to the twentieth century. By bringing together cultural historians of the histories of knowledge, emotions, finance, and global intellectual history, Threatened Knowledge is a useful tool for all students and scholars of the history of knowledge and science on a global scale.

Bu makalede Giritli Sırrı Paşa’nın (1844-1895) Şerhu’l-Akāid Tercümesi analiz edilmektedir. Makalede öncelikle Sırrı Paşa’nın entelektüel arka planı ve diğer eserlerine değinilerek tercüme tarihsel bağlamına yerleştirmeye çalışıldı. Özellikle mütercimin kelâm tasavvurunu yansıtan mukaddime kısmına dikkat çekildi. Mâtürîdî kelâmına dair klasik bir metnin on dokuzuncu yüzyıl Osmanlı okuyucusu için Şerhu’l-Akāid’in diğer şerh ve haşiyelerindeki farklı yorumları içerecek şekilde tercümenin nasıl genişlediği gösterildi. Tercümede farklı görüşlerin bir araya toplanması, aynı mesele karşısında farklı yaklaşımların birbirleriyle karşılaştırılabilmesini sağlamaktadır. Sırrı Paşa sadece metni tercüme edip diğer (...) yorumları nakletmekle kalmamış, kendi yorumlarını da ortaya koymuştur. Bu nedenle bu tercümeyi “yorumlu tercüme” olarak adlandırmaktayız. Örnek olarak bu çalışma Mâtürîdî ve Eşʿarî ekolleri arasındaki temel ihtilaflardan biri olarak görülen irâde-i cüzʾiyye kavramı üzerine odaklanmaktadır. Sırrı Paşa ve faydalandığı kaynaklardan Cevdet Paşa bu meselede Mâtürîdî görüşü benimsemişlerdir. (shrink)

Using dimensional analysis, we demonstrate that it is possible to quantify changes in the topological structure of cardiac dynamics over long periods of time. A method was developed to calculate a dimension-like measure (referred to here as apparent dimension) from a correlation algorithm within a data window of 500 heart beats which is moved in equidistant steps over the time series of the RR intervals over 24 hours. The correspondence between the apparent dimension and the correlation dimension was tested using (...) artificial data sequences. Furthermore 24 hour electrocardiographic recordings of two healthy subjects and of a patient with acute myocardial infarction were examined. The reliability of the analysis could be demonstrated and changes in dimension reflecting physiological as well as pathophysiological changes were observed. (shrink)
