Richard Dedekind English Version
RICHARD DEDEKIND (October 6, 1831 – February 12, 1916) by HEINZ KLAUS STRICK, Germany The biography of JULIUS WILHELM RICHARD DEDEKIND begins and ends in Braunschweig (Brunswick): The fourth child of a professor of law at the Collegium Carolinum, he attended the Martino-Katherineum, a traditional gymnasium (secondary school) in the city. At the age of 16, the boy, who was also a highly gifted musician, transferred to the Collegium Carolinum, an educational institution that would pave the way for him to enter the university after high school. There he prepared for future studies in mathematics. In 1850, he went to the University at Göttingen, where he enthusiastically attended lectures on experimental physics by WILHELM WEBER, and where he met CARL FRIEDRICH GAUSS when he attended a lecture given by the great mathematician on the method of least squares. GAUSS was nearing the end of his life and at the time was involved primarily in activities related to astronomy. After only four semesters, DEDEKIND had completed a doctoral dissertation on the theory of Eulerian integrals. He was GAUSS’s last doctoral student. (drawings © Andreas Strick) He then worked on his habilitation thesis, in parallel with BERNHARD RIEMANN, who had also received his doctoral degree under GAUSS’s direction not long before. In 1854, after obtaining the venia legendi (official permission allowing those completing their habilitation to lecture), he gave lectures on probability theory and geometry. Since the beginning of his stay in Göttingen, DEDEKIND had observed that the mathematics faculty, who at the time were mostly preparing students to become secondary-school teachers, had lost contact with current developments in mathematics; this in contrast to the University of Berlin, at which PETER GUSTAV LEJEUNE DIRICHLET taught. -

From Arthur Cayley Via Felix Klein, Sophus Lie, Wilhelm Killing, Elie Cartan, Emmy Noether and Superstrings to Cantorian Space–Time
Available online at www.sciencedirect.com Chaos, Solitons and Fractals 37 (2008) 1279–1288 www.elsevier.com/locate/chaos From Arthur Cayley via Felix Klein, Sophus Lie, Wilhelm Killing, Elie Cartan, Emmy Noether and superstrings to Cantorian space–time L. Marek-Crnjac Institute of Mathematics, Physics and Mechanics, Jadranska ulica 19, P.O. Box 2964, SI-1001 Ljubljana, Slovenia Abstract In this work we present a historical overview of mathematical discoveries which lead to fundamental developments in super string theory, super gravity and finally to E-infinity Cantorian space–time theory. Cantorian space–time is a hierarchical fractal-like semi manifold with formally infinity many dimensions but a finite expectation number for these dimensions. The idea of hierarchy and self-similarity in science was first entertain by Right in the 18th century, later on the idea was repeated by Swedenborg and Charlier. Interestingly, the work of Mohamed El Naschie and his two contra parts Ord and Nottale was done independently without any knowledge of the above starting from non- linear dynamics and fractals. Ó 2008 Published by Elsevier Ltd. 1. Introduction Many of the profound mathematical discovery and dare I say also inventions which were made by the mathemati- cians Arthur Cayley, Felix Klein, Sophus Lie, Wilhelm Killing, Elie Cartan and Emmy Noether [1] are extremely important for high energy particles in general [2] as well as in the development of E-infinity, Cantorian space–time the- ory [3,4]. The present paper is dedicated to the historical background of this subject. 2. Arthur Cayley – beginner of the group theory in the modern way Arthur Cayley was a great British mathematician. -

Gillian Barker and Philip Kitcher, Philosophy of Science: A New Introduction (Oxford: Oxford University Press, 2014). Other readings and videos – Posted on Canvas. Course Objectives The objective of this course is to provide an overview of the main issues in contemporary philosophy of science. These issues include the nature and goals of scientific explanation, the validation of scientific knowledge, the historical development of scientific knowledge, and the ontological import of scientific knowledge. The questions covered under these topics include: "What form do scientific explanations take?", "How do we validate theoretical hypotheses?", "What is the distinction between normal science and revolutionary science?", and "Are the postulated entities of science to be taken as real, existing entities (even when they are unobservable in principle) or, rather, are they (along with the theory of which they form a part) to be taken as instruments for the achievement of certain scientific goals?" The course will also provide students with an understanding of the activity of philosophy: How philosophers ask questions, how they think about and attempt to answer them, and how they critique the answers given by others as they provide their own alternative answers. Course Evaluation Quizzes There will be regular quizzes based on assigned readings and on class lectures. The purpose of these quizzes is to encourage students to read, study, and identify any areas in which further reading study is required. -
Philosophy of Science -----Paulk
PHILOSOPHY OF SCIENCE -----PAULK. FEYERABEND----- However, it has also a quite decisive role in building the new science and in defending new theories against their well-entrenched predecessors. For example, this philosophy plays a most important part in the arguments about the Copernican system, in the development of optics, and in the Philosophy ofScience: A Subject with construction of a new and non-Aristotelian dynamics. Almost every work of Galileo is a mixture of philosophical, mathematical, and physical prin~ a Great Past ciples which collaborate intimately without giving the impression of in coherence. This is the heroic time of the scientific philosophy. The new philosophy is not content just to mirror a science that develops independ ently of it; nor is it so distant as to deal just with alternative philosophies. It plays an essential role in building up the new science that was to replace 1. While it should be possible, in a free society, to introduce, to ex the earlier doctrines.1 pound, to make propaganda for any subject, however absurd and however 3. Now it is interesting to see how this active and critical philosophy is immoral, to publish books and articles, to give lectures on any topic, it gradually replaced by a more conservative creed, how the new creed gener must also be possible to examine what is being expounded by reference, ates technical problems of its own which are in no way related to specific not to the internal standards of the subject (which may be but the method scientific problems (Hurne), and how there arises a special subject that according to which a particular madness is being pursued), but to stan codifies science without acting back on it (Kant). -

Mathematical Induction - a miscellany of theory, history and technique Theory and applications for advanced secondary students Part 4 Peter Haggstrom This work is subject to Copyright. It is a chapter in a larger work. You can however copy this chapter for educational purposes under the Statutory License of the Copyright Act 1968 - Part VB For more information [email protected] Copyright 2009 [email protected] The building blocks of Gödelʼs Theorem The foundations of Gödel’s Theorem (ie his undecidability theorem) are to be found in about 50 papers contained in a book by Jean van Heijenoort:, “From Frege to Gödel: A Source Book in Mathematical Logic, 1879 - 1931”. Every serious logic student has read this book. Van Heijenoort is worth mentioning even if only for his colourful past which is described by Benjamin H Yandell in his book “The Honors Class: Hilbert’s Problems and Their Solvers”, A K Peters, 2002, page 66. I quote in full: “ I assumed van Heijenoort was merely a logician as I gratefully pored over his book and was astounded when I learned that as a young man, in the 1930s, he had followed Leon Trotsky from Turkey to France to Norway to Mexico, as his body guard and secretary. Anita Feferman’s ”From Trotsky to Gödel”: The Life of Jean van Heijenoort” tells van Heijenoort’s remarkable story. Trotsky and his camp were pursued by Stalinist agents; van Heijenoort always packed a gun. Van Heijenoort had an affair with an artist Frida Kahlo. He epitomized cool and was attractive to women, and this continued even after he became a logician, He had grown tired of the rigors of life with Trotsky and traveled to New York in 1939 on a somewhat vague mission. -
A Prologue to Charles Sanders Peirce's Theory of Signs
In Lieu of Saussure: A Prologue to Charles Sanders Peirce’s Theory of Signs E. San Juan, Jr. Language is as old as consciousness, language is practical consciousness that exists also for other men, and for that reason alone it really exists for me personally as well; language, like consciousness, only arises from the need, the necessity, of intercourse with other men. – Karl Marx, The German Ideology (1845-46) General principles are really operative in nature. Words [such as Patrick Henry’s on liberty] then do produce physical effects. It is madness to deny it. The very denial of it involves a belief in it. – C.S. Peirce, Harvard Lectures on Pragmatism (1903) The era of Saussure is dying, the epoch of Peirce is just struggling to be born. Although pragmatism has been experiencing a renaissance in philosophy in general in the last few decades, Charles Sanders Peirce, the “inventor” of this anti-Cartesian, scientific- realist method of clarifying meaning, still remains unacknowledged as a seminal genius, a polymath master-thinker. William James’s vulgarized version has overshadowed Peirce’s highly original theory of “pragmaticism” grounded on a singular conception of semiotics. Now recognized as more comprehensive and heuristically fertile than Saussure’s binary semiology (the foundation of post-structuralist textualisms) which Cold War politics endorsed and popularized, Peirce’s “semeiotics” (his preferred rubric) is bound to exert a profound revolutionary influence. Peirce’s triadic sign-theory operates within a critical- realist framework opposed to nominalism and relativist nihilism (Liszka 1996). I endeavor to outline here a general schema of Peirce’s semeiotics and initiate a hypothetical frame for interpreting Michael Ondaatje’s Anil’s’ Ghost, an exploratory or Copyright © 2012 by E. -
A Century of Mathematics in America, Peter Duren Et Ai., (Eds.), Vol
Garrett Birkhoff has had a lifelong connection with Harvard mathematics. He was an infant when his father, the famous mathematician G. D. Birkhoff, joined the Harvard faculty. He has had a long academic career at Harvard: A.B. in 1932, Society of Fellows in 1933-1936, and a faculty appointmentfrom 1936 until his retirement in 1981. His research has ranged widely through alge bra, lattice theory, hydrodynamics, differential equations, scientific computing, and history of mathematics. Among his many publications are books on lattice theory and hydrodynamics, and the pioneering textbook A Survey of Modern Algebra, written jointly with S. Mac Lane. He has served as president ofSIAM and is a member of the National Academy of Sciences. Mathematics at Harvard, 1836-1944 GARRETT BIRKHOFF O. OUTLINE As my contribution to the history of mathematics in America, I decided to write a connected account of mathematical activity at Harvard from 1836 (Harvard's bicentennial) to the present day. During that time, many mathe maticians at Harvard have tried to respond constructively to the challenges and opportunities confronting them in a rapidly changing world. This essay reviews what might be called the indigenous period, lasting through World War II, during which most members of the Harvard mathe matical faculty had also studied there. Indeed, as will be explained in §§ 1-3 below, mathematical activity at Harvard was dominated by Benjamin Peirce and his students in the first half of this period. Then, from 1890 until around 1920, while our country was becoming a great power economically, basic mathematical research of high quality, mostly in traditional areas of analysis and theoretical celestial mechanics, was carried on by several faculty members. -

The entire dissertation is devoted to an extensive and in-depth analysis of this single paper in the form of commentary. All ¯fteen sections of the New List are examined. Rather than considering the textual genesis of the New List, or situating the work narrowly in the early philosophy of Peirce, as previous scholarship has done, this work pursues the genuine philosophical content of the New List, while paying attention to the later philosophy of Peirce as well. Immanuel Kant's Critique of Pure Reason is also taken into serious account, to which Peirce contrasted his new theory of categories. iii Table of Contents List of Figures . ix Acknowledgements . xi General Introduction 1 The Subject of the Dissertation . 1 Features of the Dissertation . -
The Generalization of Logic According to G.Boole, A.De Morgan
South American Journal of Logic Vol. 3, n. 2, pp. 415{481, 2017 ISSN: 2446-6719 Squaring the unknown: The generalization of logic according to G. Boole, A. De Morgan, and C. S. Peirce Cassiano Terra Rodrigues Abstract This article shows the development of symbolic mathematical logic in the works of G. Boole, A. De Morgan, and C. S. Peirce. Starting from limitations found in syllogistic, Boole devised a calculus for what he called the algebra of logic. Modifying the interpretation of categorial proposi- tions to make them agree with algebraic equations, Boole was able to show an isomorphism between the calculus of classes and of propositions, being indeed the first to mathematize logic. Having a different purport than Boole's system, De Morgan's is conceived as an improvement on syllogistic and as an instrument for the study of it. With a very unusual system of symbols of his own, De Morgan develops the study of logical relations that are defined by the very operation of signs. Although his logic is not a Boolean algebra of logic, Boole took from De Morgan at least one central notion, namely, the one of a universe of discourse. Peirce crit- ically sets out both from Boole and from De Morgan. Firstly, claiming Boole had exaggeratedly submitted logic to mathematics, Peirce strives to distinguish the nature and the purpose of each discipline. Secondly, identifying De Morgan's limitations in his rigid restraint of logic to the study of relations, Peirce develops compositions of relations with classes. From such criticisms, Peirce not only devises a multiple quantification theory, but also construes a very original and strong conception of logic as a normative science.
