Marc J. Ratcliff – författare

The eighteenth century has often been viewed as a period of relative decline in the field of microscopy, as interest in microscopes seemed to wane after an intense period of discovery in the seventeenth century. As such, developments in the field during the Enlightenment have been largely overlooked. This book therefore fills a considerable gap in the study of this life science, providing a thorough analysis of what the main concerns of the field were and how microscopists learned to communicate with each other in relevant ways in order to compare results and build a new discipline. Employing a substantial body of contemporary literature from across Europe, Marc J. Ratcliff is able to present us with a definitive account of the state of research into microscopy of the period. He brings to light the little known work of Louis Joblot, re-evaluates the achievements of Abraham Trembley and gives new weight to Otto-Friedrich Müller's important contributions. The book also connects changes in instrument design to an innovative account of microscopical research during the eighteenth century and the rich social networks of communication that grew during this period. Investigating the history of microscopical research from 1680 up to 1800 also shows how scholars progressively established a modern rule on which to shape their new discipline: balancing microscopical magnification with shared vision. This rule developed in response to the diminishing size of the microscopical object during the course of the eighteenth century, from dry minute organisms such as insects, to aquatic minute bodies such as polyps, and finally to aquatic invisible organisms, thus completing the scholar's quest to study the invisible. This book will be essential reading for historians of microscopy, epistemologists, and for historians of the life sciences in the modern period.

This book presents a collection of studies on the circulation of Jean Piaget’s ideas and works between Europe and Latin America, and how this transnational legacy influenced different fields of research and practice, such as psychology, education and philosophy. The volume brings together contributions presented at the International Colloquium Jean Piaget in Brazil and Latin America, held during the 38th Annual Helena Antipoff Meeting, organized by the Federal University of Minas Gerais, Brazil, in collaboration with the University of Geneva, Switzerland.  The book is organized in three parts. Chapters in the first part analyze Piaget’s role as a builder of an international network in psychology, education and peace promotion in the 20th century, with a special focus on the circulation of his ideas and works between Switzerland and France. The second part focuses on historical and contemporary dialogues, conflicts and controversies between Piaget and other authors, such as Henri Wallon, Carl Rogers, Jürgen Habermas, and, especially, Helena Antipoff, the Russian-Brazilian psychologist and educator who was one of the first researchers to introduce Piaget in Brazil and to establish a bridge between Latin America and the Geneva school of psychological and educational sciences. Finally, chapters in the third part of the book explore different aspects of the reception and appropriation of Piaget’s works and ideas in the Brazilian context.   The Transnational Legacy of Jean Piaget: A View from the 21st Century will be of interest to researchers in different fields within the human and social sciences, such as developmental, educational and school psychologists; educators; philosophers and historians of psychology and education interested in understanding how Piaget’s progressist ideas have contributed to the development of psychological and educational sciences in Europe and Latin America. Some chapters ofthis book were originally written in Portuguese and French and translated into English with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content.
