"The book offers a comprehensive and accessible introduction to the fundamental concepts of classical field theory, covering all the essential aspects required in a formal course. Presented in an innovative and modern format, the content unfolds through a dynamic and engaging conversation between two students, Diego and Aissatou. Diego, a student just beginning his course in classical field theory, faces the complex and profound concepts that this subject entails. Aïssatou, an undoubtedly brilliant young woman, patiently guides him, clearly and precisely explaining the more abstract notions and practical applications of the theory. As their conversation progresses, the reader is led through a pedagogical narrative that eases understanding, offering clear examples and clever analogies that make learning more enjoyable and less intimidating. This work is not only a detailed academic manual but also an intellectual adventure that invites the reader to explore and enjoy the wonderful world of classical field theory." (Ernesto Contreras, University of Alicante, Spain) "Written with great skill and love, this book deserves to be picked up by anyone who is engaged in or would like to engage in theoretical Physics. That is how, with capital letters, the Authors write about this science.

What is unexpected is the style of dialogue they have chosen. Dialogue - explanation through conversation - originates in the European tradition from Socrates and Plato and is realized here in the conversations of two students, Aïssatou and Diego. The surprises don't end there. Unusual, and therefore particularly impressive and pleasant, is the successful design of the text and formulas - at the level of location and font solution, and elegant photos, which reveal the hand and eye of the Author-aesthete, and the discussion of philosophical, historical, and even social aspects of science, which reach the present day. A good selection of material, and detailed explanations, sometimes repeated at different levels, make this book, written with great pedagogical skill, a reliable assistant in travelling through classic field theories!"
