Nonlinear partial differential equations (PDE) are at the core of mathematical modeling. In the past decades and recent years, multiple analytical methods to study various aspects of the mathematical structure of nonlinear PDEs have been developed. Those aspects include C- and S-integrability, Lagrangian and Hamiltonian formulations, equivalence transformations, local and nonlocal symmetries, conservation laws, and more. Modern computational approaches and symbolic software can be employed to systematically derive and use such properties, and where possible, construct exact and approximate solutions of nonlinear equations. This book contains a consistent overview of multiple properties of nonlinear PDEs, their relations, computation algorithms, and a uniformly presented set of examples of application of these methods to specific PDEs. Examples include both well known nonlinear PDEs and less famous systems that arise in the context of shallow water waves and far beyond. The book will beof interest to researchers and graduate students in applied mathematics, physics, and engineering, and can be used as a basis for research, study, reference, and applications.

Dieses Buch macht die überraschende Vielfalt der Personen und Tätigkeiten in der Radioaktivitätsforschung sichtbar. Dabei wird der Begriff der wissenschaftlichen Arbeit neu konzeptualisiert. Neben die Forschungsarbeit im Labor treten scheinbare Rand-, Neben- und Routinetätigkeiten, die für die Radioaktivitätsforschung als Disziplin von zentraler Bedeutung waren.Badeärzte, Industriechemiker und Bergbaubeamte waren an der Erforschung der neuen Substanzen und Strahlen ebenso beteiligt wie eine vergleichsweise hohe Zahl von Frauen. Die erste umfassende Studie zur deutschsprachigen Radioaktivitätsforschung im vorderen Teil des Buches offenbart die Ausnahmestellung der Hauptstädte Berlin und Wien für die Forschung ebenso wie fruchtbares akademisches Leben in der Provinz; sie zeigt, wie das neue Gebiet an den Hochschulen in die Lehre einzog und welchen Beitrag Professoren, Privatdozenten und Promovierende zur Forschung leisteten. Erstmals wird auch die Bedeutung der Wasseruntersuchungen aufgezeigt, die durch die Hoffnung auf radioaktive Heilquellen angetrieben wurden.Im zweiten Teil werden in internationaler Perspektive unsichtbare und in der Geschichtsschreibung oft wenig beachtete Facetten der „Arbeit mit dem Radium“ untersucht. So mussten Instrumente und radioaktive Präparate überhaupt erst hergestellt und in Umlauf gebracht werden. Auch die Etablierung von Nachweismethoden für Radioaktivität erforderte viel Arbeit, von der niemand sprach. Dienstleistungen wie die Entwicklung therapeutisch nutzbarer Präparate, Gutachtertätigkeiten, die Herausgabe einer Zeitschrift oder die Organisation eines Kongresses werden als integraler Bestandteil der wissenschaftlichen Arbeit in ihrer Bedeutung dargestellt. Eine Reflexion zur Arbeitsorganisation und zum disziplinären Status bündelt die Ergebnisse in einer neuen Gesamtsicht auf die frühe Radioaktivitätsforschung.

Athanasius Kircher, the eminent 17th-century German Jesuit professor of mathematics at the Roman College emerges as a captivating figure within the pages of this monograph by Agustín Udías. Aptly deemed'the man who knew everything,'Kircher's thirty-two comprehensive works, spanning an array of subjects, provide a unique lens into his visionary perspectives. This book delves into three selected works where Kircher unveils his conceptualization of the Earth, termed the'Geocosmos,'treated magnetism as a cosmic and spiritual force, and embarks on a cosmic exploration from Earth to the stars. From his groundbreaking speculations on the Earth's interior, attributing earthquakes and volcanoes to intricate channels of air, water, and fire, to his cosmic journey accompanied by the ethereal spirit Cosmiel, Kircher's enduring allure persists. Despite variance from contemporary knowledge, situated at the beginning of modern science, Kircher's proposals of the structure of the Earth's interior, cosmic magnetic theories, and space journey to the stars offer a compelling glimpse into the intellectual landscape of a bygone era, making this book an essential exploration for scholars seeking a nuanced understanding of Kircher's profound influence.

Why do you lean in a bend? Why does a sprinter slow down before the finish line? Why do golf balls have dimples? Why do you swim better slightly underwater?

This book provides an introduction to real analysis, a fundamental topic that is an essential requirement in the study of mathematics. It deals with the concepts of infinity and limits, which are the cornerstones in the development of calculus. Beginning with some basic proof techniques and the notions of sets and functions, the book rigorously constructs the real numbers and their related structures from the natural numbers. During this construction, the readers will encounter the notions of infinity, limits, real sequences, and real series. These concepts are then formalised and focused on as stand-alone objects. Finally, they are expanded to limits, sequences, and series of more general objects such as real-valued functions. Once the fundamental tools of the trade have been established, the readers are led into the classical study of calculus (continuity, differentiation, and Riemann integration) from first principles. The book concludes with an introduction to the study of measures and how one can construct the Lebesgue integral as an extension of the Riemann integral. This textbook is aimed at undergraduate students in mathematics. As its title suggests, it covers a large amount of material, which can be taught in around three semesters. Many remarks and examples help to motivate and provide intuition for the abstract theoretical concepts discussed. In addition, more than 600 exercises are included in the book, some of which will lead the readers to more advanced topics and could be suitable for independent study projects. Since the book is fully self-contained, it is also ideal for self-study.

This book highlights recent developments in the representation theory of finite solvable groups, which seeks to connect group theory to linear algebra in ways that allow for better study of the groups in question. Over the last several decades, a number of results in the representations of solvable groups have been proven using so-called “large orbit” theorems. This book provides an extensive survey of the current state of the large-orbit theorems. The authors outline the proofs of the large orbit theorems to provide an overview of the topic, then demonstrate how these theorems can be used to prove new results about solvable groups.

This book is a unified treatment of the most important core developments in the theory of completely regular semigroup theory as it stands today. This volume focuses on the lattice of varieties of completely regular semigroups. Since any in-depth study of the lattice of varieties requires an understanding of free completely regular semigroups, the book begins by describing the free object on countably infinite sets and the properties of the lattice of fully invariant congruences on the free object. The authors introduce various associated relations and operators on the lattice of varieties of completely regular semigroups. Following that, the book covers the sublattice of varieties of bands with a focus on the influence of that sublattice on the structure of the whole lattice. The book concludes with the remarkable theorem due to Polák describing the whole lattice of varieties of completely regular as a subdirect product of lattices,some of which are well understood. The authors include recent advances, insights, results, and techniques throughout the book.

This book focuses on stability analysis and control design approaches for multi-agent systems under network-induced constraints. A hybrid system approach is introduced to address the cooperative control problem of networked multi-agent systems, and several important topics such as asynchronous sampled data cooperative control, hybrid event-triggered cooperative control, and reset-based cooperative control are studied under the hybrid system framework. The special feature of this book is that a hybrid systems approach is proposed for the cooperative control of multi-agent systems, which is beneficial for relaxing the conservativeness of stability analysis and network parameter computation. Interested readers can learn a novel approach to cooperative control of multi-agent systems, and this book can benefit researchers, engineers, and graduate students in the fields of multi-robot cooperation, unmanned aerial vehicle formation, control engineering, etc.

Wesentliche Zielsetzung dieser Arbeit ist ein theoretisch fundierter und empirisch abgestützter Beitrag zur Messung einer Facette diagnostischer Kompetenz bei Lehrpersonen der Primarstufe – dem Erkennen von Stärken und Schwächen in Lösungen von Schülerinnen und Schülern im Größenbereich Gewichte. Diagnostische Kompetenz gilt als Grundlage dafür, den Grad von Verständnis in Lösungen von Schülerinnen und Schülern zu erkennen. Ebenso gilt sie als Voraussetzung dafür, fehlerhafte und richtige Überlegungen zu identifizieren und deren Genese zu interpretieren. Diagnostische Kompetenz reliabel und valide zu messen, gestaltet sich in der Umsetzung jedoch oft schwierig, da Kombinationen von Wissen und Können gemessen werden sollen. Oft findet deshalb in der Forschung eine Fokussierung auf die Urteilsakkuratheit statt. Um das Feld von Untersuchungen, bei denen die Urteilsakkuratheit als Paradigma im Vordergrund steht, zu erweitern, wurde ein Testinstrument entwickelt, mit dem der Fokus auf das Erkennen von Stärken und Schwächen gelegt wird. Auf der Basis der Ergebnisse der Arbeit kann gezeigt werden, dass einerseits das Erkennen von Stärken und Schwächen durch eine Intervention trainiert und verbessert werden kann und andererseits, dass diese Veränderungen mit dem dafür entwickelten Kompetenzmessinstrument erfasst werden können.

Felix Hausdorff is a singular phenomenon in the history of science. As a mathematician, he played a major role in shaping the development of modern mathematics in the 20th century. He founded general topology as an independent mathematical discipline, while enriching set theory with a number of fundamental concepts and results. His general approach to measure and dimension led to profound developments in numerous mathematical disciplines, and today Hausdorff dimension plays a central role in fractal theory with its many fascinating applications by means of computer graphics. Hausdorff's remarkable mathematical versatility is reflected in his published work: today, no fewer than thirteen concepts, theorems and procedures carry his name. Yet he was not only a creative mathematician – Hausdorff was also an original philosophical thinker, a poet, essayist and man of letters. Under the pseudonym Paul Mongré, he published a volume of aphorisms, an epistemological study, abook of poetry, an oft-performed play, and a number of notable essays in leading literary journals. As a Jew, Felix Hausdorff was increasingly persecuted and humiliated under the National Socialist dictatorship. When deportation to a concentration camp was imminent, he, along with his wife and sister-in law, decided to take their own lives. This book will be of interest to historians and mathematicians already fascinated by the rich life of Felix Hausdorff, as well as to those readers who wish to immerse themselves in the intricate web of intellectual and political transformations during this pivotal period in European history.

This textbook is a second edition of the successful, Mathematical Logic: On Numbers, Sets, Structures, and Symmetry. It retains the original two parts found in the first edition, while presenting new material in the form of an added third part to the textbook. The textbook offers a slow introduction to mathematical logic, and several basic concepts of model theory, such as first-order definability, types, symmetries, and elementary extensions. Part I, Logic Sets, and Numbers, shows how mathematical logic is used to develop the number structures of classical mathematics. All necessary concepts are introduced exactly as they would be in a course in mathematical logic; but are accompanied by more extensive introductory remarks and examples to motivate formal developments. The second part, Relations, Structures, Geometry, introduces several basic concepts of model theory, such as first-order definability, types, symmetries, and elementary extensions, and shows how they are usedto study and classify mathematical structures. The added Part III to the book is closer to what one finds in standard introductory mathematical textbooks. Definitions, theorems, and proofs that are introduced are still preceded by remarks that motivate the material, but the exposition is more formal, and includes more advanced topics. The focus is on the notion of countable categoricity, which analyzed in detail using examples from the first two parts of the book. This textbook is suitable for graduate students in mathematical logic and set theory and will also be of interest to mathematicians who know the technical aspects of the subject, but are not familiar with its history and philosophical background.

This textbook introduces bioinformatics to students in mathematics with no biology background assumed and it provides solid mathematical tools for biology students along with an understanding of how to implement them in bioinformatics problems. In addition to the basics, the text offers new approaches to understanding biological sequences. The concise presentation distinguishes itself from others on the subject, discussing and providing principles that relate to current open problems in bioinformatics as well as considering a variety of models. The convex hull principle is highlighted, opening a new interdisciplinary research area at the intersection of biology, mathematics, and computer science. Prerequisites include first courses in linear algebra, probability and statistics, and mathematical analysis. Researchers in mathematics, biology, and math-biology, will also find aspects of this text useful. This textbook is written based on the authors'research works that have been published in various journals along with the lecture notes used when teaching bioinformatics courses at the University of Illinois at Chicago and at Tsinghua University. The content may be divided into two parts. The first part includes three chapters, introducing some basic concepts. Chapter 1 provides biological background in molecular biology for mathematicians. Chapter 2 describes biological databases that are commonly used. Chapter 3 is concerned with alignment methods including global/local alignment, heuristic alignment, and multiple alignment. The second part consisting of five chapters, describes several bioinformatics principles using a rigorous mathematical formulation. Chapter 4 introduces the time-frequency spectral principle and its applications in bioinformatics. In Chapters 5 and 6, two strategies are used, the graphical representation and the natural vector method, to represent biological sequences, and conduct sequence comparison and phylogenetic analysis without alignment. Chapter 7 presents the convex hull principle and shows how it can be used to mathematically determine whether a certain amino acid sequence can be a protein. The last chapter summarizes additional mathematical ideas relating to sequence comparisons, such as new feature vectors and metrics. This part focuses on the governing principle in biology and provides plenty of alignment-free methods, which cannot be found in any other book.

This book addresses interconnections between contemporary advances in mathematics, especially algebra, with applications in the social sciences and the arts. It promotes the idea that knowledge cannot remain in disciplinary silos, rather, it belongs to all people, and is dedicated to associative relationships in a variety of mathematics applications, from sociology to linguistics, including anthropology, semiotics, education, and cognitive science. Contributions illuminate some of the ways in which algebra is developed, learned, understood, communicated, and applied in the social sciences and the humanities.The content in this book has its origins in a conference, Mathematics for Social Sciences and Arts–Algebraic Modelling, virtually hosted by the Faculty of Mechanical Engineering, University of Niš, Serbia, from the 24th to the 26th of May, 2021. This conference brought together scholars from various disciplines and geographic regions and focused on thejuxtaposition of algebra and social science applications. The conference organizers, higher education institutes from four different continents, invited leading scientists in social sciences and algebra, to contribute to this volume.The first part of this book addresses algebraic and mathematical thinking, specifically learning and practicing mathematics from a cognitive science perspective, as well as illustrative applications to distinctly human concerns, like education and semiotics. The second part focuses on algebraic semigroups and some of their generalizations. This book and the conference that engendered it provide an example of a fruitful collaboration, in which the skills and deep knowledge of algebraic structures, modeling, social sciences and arts brought in by the authors from different countries and continents merge in harmonious ways. These expositions are a rich resource and are of interest both to mathematicians and non-mathematicians.

This book is an autobiographical interview with Chinese Academician Yuan Wang on his experience in mathematical research. The book looks back on Wang's collaboration with his teacher Hua Loo-Keng and younger scholars, offering insights into fruitful cooperation in mathematical research.In this book, Yuan Wang's path of studying Goldbach conjecture is revealed in detail from motivation to method. Then his work on algebraic number theory is traced back in a separate chapter. The book ends with two chapters which introduce Wang's interest in history of mathematics and his hobbies outside of mathematical research. Wang shows how a mathematician can in the same time be a historical and popular science writer and, in particular, a well-received calligrapher. The book is intended for undergraduate and graduate students studying number theory. Researchers who are willing to learn from the experience of an established mathematician, as well as math amateurs and general audience who are interested in Yuan Wang's life story might also find this book appealing.

Dieses Buch bietet eine umfassende Darstellung der Geschichte der indischen Mathematiker und Statistiker und deckt viele fehlende Teile der wissenschaftlichen Darstellung der mathematischen und statistischen Forschung in Bengalen (heute Westbengalen), Indien, im 19. und 20. Jahrhundert ab. Dieses Buch gibt einen kurzen historischen Überblick über die Einrichtung der ersten beiden Abteilungen an einer indischen Universität, in denen Lehre und Forschung für Graduierte eingeführt wurden. Dies war eine einzigartige Auszeichnung für die 1857 gegründete Universität von Kalkutta. Auch die Gründung des weltberühmten Indischen Statistischen Instituts (ISI) in Kalkutta wird kurz beschrieben. Leben und Werk der 16 Pioniere der mathematischen Wissenschaft, die an oben genannten Institutionen und dem ersten indische Institut für Technologie (IIT) in Indien wirkten, werden in klarer Sprache dargestellt. Einige herausragende Gelehrte, die am ISI ausgebildet wurden, Indien aber dauerhaft verließen, werden in einem eigenen Kapitel kurz vorgestellt. Dieses Buch schließt eine seit langem bestehende Lücke in der Geschichte der modernen indischen Mathematik, was das Buch für Forscher in der Geschichte der Wissenschaft und der Mathematik sehr nützlich machen wird. Das Buch ist in sehr klarer Sprache geschrieben, mit wenig mathematischem oder statistischem Jargon, was es auch für allgemeine Leser mit Interesse an Wissenschaftsgeschichte, selbst mit nicht-mathematischem, nicht-statistischem Hintergrund, sehr lesbar macht. Dieses Buch ist eine klare Darstellung des Kampfes und des Erfolges der Forscher in den mathematischen Wissenschaften in Bengalen (einem wichtigen Teil des kolonialen Indiens), die vor der internationalen Gemeinschaft der mathematischen Wissenschaftler enthüllt wird. Echte Kenner werden den Wert des Buches zu schätzen wissen, da es viele vorherrschende Missverständnisse ausräumen wird.Die Übersetzung wurde mit Hilfe von künstlicher Intelligenz durchgeführt. Eine anschließende menschliche Überarbeitung erfolgte vor allem in Bezug auf den Inhalt.

Maximilian Klein analyses nested Monte Carlo simulations for the approximation of conditional expected values. Thereby, the book deals with two general risk functional classes for conditional expected values, on the one hand the class of moment-based estimators (notable examples are the probability of a large loss or the lower partial moments) and on the other hand the class of quantile-based estimators. For both functional classes, the almost sure convergence of the respective estimator is proven and the underlying convergence speed is quantified. In particular, the class of quantile-based estimators has important practical consequences especially for life insurance companies since the Value-at-Risk falls into this class and thus covers the solvency capital requirement problem. Furthermore, a novel non parametric confidence interval method for quantiles is presented which takes the additional noise of the inner simulation into account.

After providing an overview of the basics of probability, the authors cover essential topics such as confidence intervals, hypothesis testing, and linear regression. These subjects are presented in a one semester format, suitable for engineers, scientists, and STEM students with a solid understanding of calculus. There are problems and exercises included in each chapter allowing readers to practice the applications of the concepts.

Das Verstehen der Realsituation in Modellierungsaufgaben ist eine notwendige Bedingung für einen korrekten Lösungsprozess. Eine Determinante des Textverstehens ist das Leseziel. Durch dieses kann die Aufmerksamkeit beim Lesen und Verstehen eines Textes auf lesezielrelevante Informationen gerichtet werden. Das Leseziel sollte sich konkretisieren lassen, indem die zu einer Modellierungsaufgabe zugehörige Fragestellung dem Aufgabentext vorangestellt wird. Frühere Studien zeigen, dass die Spezifizierung des Leseziels über die Voranstellung von Fragestellungen vor den Text positive Effekte auf das Leseverhalten, das Textverstehen und die Effizienz dabei induzieren kann. In zwei Studien mit Lernenden der gymnasialen Oberstufe und aus Erweiterungskursen der Realschule wurde überprüft, inwiefern diese Ergebnisse sich auf Modellierungsaufgaben übertragen lassen. In Studie 1 (N = 192) wurde der Einfluss der Position der Fragestellung auf die Lese- und Bearbeitungsdauer, das Textverstehen unddas Mathematisieren bei Modellierungsaufgaben untersucht. In Studie 2 (N = 75) wurde zudem überprüft, inwiefern die Position der Fragestellung das Leseverhalten und die Aufmerksamkeitsallokation auf (ir-)relevante Informationen in den verschiedenen Phasen des Leseprozesses beeinflusst.

This volume comprises selected papers from the SIAM International Meshing Roundtable Workshop 2023, SIAM IMR 2023, held in Amsterdam, the Netherlands, March 6-9, 2023. The IMR was started by Sandia National Laboratories in 1992 and, since 2021, it has been held under the umbrella of the Society for Industrial and Applied Mathematics (SIAM). The SIAM IMR 2023 was the first in-situ conference to be held since 2019, after two online conferences. It consisted of short courses, technical presentations from keynotes, contributed talks and research notes, a poster session and meshing contest, and discussion panels. The papers in these proceedings present novel contributions that range from theoretical advances to technical applications in engineering, geometric modeling, computer graphics, visualization, and machine learning.

In this open access book Milena Damrau investigates the understanding of generality of mathematical statements in first-year university students and its relation to other proof-related activities. Through an experimental study, she particularly analyses the effect of different types of arguments (empirical, generic, and ordinary proofs) and statements (familiar and unfamiliar, as well as true and false ones) on several proof-related activities. The results reveal students'struggles with the concept of generality, how their understanding of generality is related to proof reading and construction and how different types of arguments and statements impact students'performance in other proof-related activities. The findings offer valuable insights for improving mathematics courses at the transition from school to university and highlight the need for more experimental studies in mathematics education.

Dutch scientist Christiaan Huygens (1629-1695) left an indelible mark on the fields of mathematics, physics, astronomy, and geophysics. Despite his groundbreaking contributions, history has often overlooked his pivotal role. While two of the most famous achievements in physics are Newton's theory of gravity and Einstein's general theory of relativity, less well-known is that Huygens provided central elements to these theories. This book stands to correct that deficit. For example, we show how Huygens used symmetry arguments to derive conservation laws for momentum and for energy, and what Einstein later called the principle of equivalence to derive the formula for centrifugal force. In 1689, Huygens visited Newton. Together, they walked the streets of London. Newton had recently finished his masterpiece, Principia, expounding his laws of motion and the law of universal gravitation. Huygens had essentially completed his life's work by then, building on Archimedes, Leonardo da Vinci, Galileo, Descartes, Fermat, Pascal and his own ingenuity. He had established fame as an instrument maker (telescope, pendulum clock, planetarium). He had invented the 31 tone system. He had pioneered the first principles of remote sensing. He had discovered the rings of Saturn. He had formulated the wave theory of light. What would walking with Christiaan reveal? This book gives the result in nine chapters, namely: spontaneous order, the speed of light, Huygens'principle, the telescope, the pendulum clock, Huygens-Fresnel principle, special relativity, centrifugal force, and curvature. In addition, there is a chapter titled What Huygens could have written on diffraction, and a chapter titled Huygens and Geophysics. Mentally walking with Christiaan, browsing his collected works — a true treasure trove for puzzle enthusiasts — and rethinking his ideas creates a vivid impression of scientific life in the 17th century, an appreciation that it is remarkably similar to ours, and an understanding of Huygens'significant and lasting contributions to science.

Politische Themen mit wissenschaftlichem Bezug werden medial immer präsenter. In Talkshows, Zeitungen und politischen Beratungsgremien finden oft Expertinnen und Experten mit Physikausbildung Gehör. Egal, ob es um Klimawandel, Finanzmarktcrashs, Pandemiepolitik oder erneuerbare Energien geht: wir müssen den Aussagen dieser Expertinnen und Experten blind vertrauen, wenn wir selbst kein Fachwissen besitzen. In diesem Buch werden physikalische Grundlagen hinter gesellschaftlich relevanten Themen auf eine allgemeinverständliche Weise erklärt. Dabei geht es vor allem darum, die für die Physik typischen Denkweisen klar zu machen. Auf welchen Grundlagen (Mechanik, Elektrodynamik, Quantentheorie, Feldtheorien, Relativitätstheorien, Statistische Physik) beruhen eigentlich physikalische Aussagen? Wie sind diese Grundlagen entstanden? Wie erstellt man in der Physik Modelle zur Beschreibung komplexer Themen? Was ist „Wahrheit'in Wissenschaften?Wie ist das Verhältnis von Modellen zur Wirklichkeit? Beim Beantworten dieser und vieler weiterer Fragen hat der Autor darauf geachtet, nur Mathematik vorauszusetzen, die das Niveau der Mittelstufe nicht überschreitet. Der vorliegende Band richtet sich an alle, die für Entscheidungen und Urteile ein einfaches aber solides Verständnis des physikalischen Denkens suchen: sei es im Alltag, in Unternehmen oder in der Politik.

The abbacus was a thorough and complete system of arithmetical calculations, which saw its dawn in the Indian and Arabic tradition of the Middle Ages, but which was developed in its fully fledged aspects especially in Italy, between Genoa, Milan, Venice and the region of Umbria. In this monograph, Høyrup explores how the abbacus tradition has developed in Europe, with a focus on Italy and Germany between the 14th and the 17th Century. With the analysis of texts from Fibonacci, Pacioli, and Stifel to name but a few, this book offers a critical historical analysis of the development and diffusion of a tradition of calculus that has deeply influenced the way in which mathematics has developed in the West. The primary purpose of the book is to present a fairly detailed portrait of the abbacus tradition as it developed historically; as will be argued, Fibonacci was much less important for the emergence of this tradition than mostly assumed – but since his importance isbroadly taken for granted, that argument needs to be made, for which reason Fibonacci's Liber Abbaci is also described and analyzed in some depth. A secondary purpose is to show how the adoption of abbacus mathematics in German lands gave rise to the creation of a different tradition. The end of the book investigates the interplay of abbacus algebra with other intellectual currents which turned the whole mathematical undertaking upside-down in the 17th Century.​

Wozu braucht man eigentlich Mathematik? Haben Sie sich das auch schon gefragt oder sind Sie selbst Mathematiker/-in und hören dies oft?Mathematik ist weit mehr als die Suche nach der nächsten Primzahl oder dem x-ten Beweis des Satzes von Pythagoras. Mathematik ist eine zentrale Schlüsseltechnologie für viele Wissenschaftsbereiche. Die Frage, ob es einen Klimawandel gibt und wie man Veränderungen im Klima beobachtet, kann ohne Mathematik genauso wenig beantwortet werden wie die Frage, wie sich eine Pandemie ausbreitet. Viele weitere Beispiele werden in dem Buch angesprochen.In einem lockeren Erzählstil erläutert der Autor, wo überall Mathematik verborgen ist und wie man mit einfachen Mitteln schon verstehen kann, wie brisante Probleme gelöst werden. Vorausgesetzt werden (je nach Kapitel) teils gar keine Mathematik-Vorkenntnisse bis maximal zum Abitur-Wissen.

Aus Perspektive der Mathematikdidaktik stellt das Stellenwertsystem im Lernprozess häufig eine Hürde dar, der möglichst frühzeitig begegnet werden sollte. Gleichzeitig scheint eine Hörschädigung den mathematischen Lernprozess negativ zu beeinflussen. Im Rahmen dieser Forschungsarbeit werden zum einen Design-Prinzipien sowie ein Lehr-Lernarrangement zum Zehnerübergang entwickelt, die eine Möglichkeit der frühzeitigen Anbahnung eines Stellenwertverständnisses (speziell mit Blick auf den Förderschwerpunkt Hören und Kommunikation) darstellen. Hierbei wird bewusst eine von gängigen Erarbeitungen abweichende Übergänge fokussierende Herangehensweise gewählt, die jedoch als Ergänzung zu verstehen ist und zudem im Hinblick auf den weiteren Verlauf der Lehr- und Lernprozesse anschlussfähig ist. Zum anderen werden lokale Theorien zu Lehr- und Lernprozessen am Zehnerübergang generiert. Somit bietet die Arbeit erste Einsichten zu möglichen Hürden sowie Anhaltspunkte für Hilfestellungen und Strategien zum Umgang mit Herausforderungen, insbesondere im Kontext des Förderschwerpunkts Hören und Kommunikation.
