Both a history and a metahistory, Representing Electrons focuses on the development of various theoretical representations of electrons from the late 1890s to 1925 and the methodological problems associated with writing about unobservable scientific entities.

Using the electron—or rather its representation—as a historical actor, Theodore Arabatzis illustrates the emergence and gradual consolidation of its representation in physics, its career throughout old quantum theory, and its appropriation and reinterpretation by chemists. As Arabatzis develops this novel biographical approach, he portrays scientific representations as partly autonomous agents with lives of their own. Furthermore, he argues that the considerable variance in the representation of the electron does not undermine its stable identity or existence.

Raising philosophical issues of contentious debate in the history and philosophy of science—namely, scientific realism and meaning change—Arabatzis addresses the history of the electron across disciplines, integrating historical narrative with philosophical analysis in a book that will be a touchstone for historians and philosophers of science and scientists alike.

Review Quotes
Ernan McMullin, director emeritus of the Program in History and Philosophy of Science, University of Notre Dame
“More than forty years ago, Kuhn urged philosophers of science to take the history of science as a guideline in their own work. This book is a splendid example of what can result when they do. Critics of scientific realism have pointed to the way in which terms like ‘electron’ can change over the course of time, sometimes in drastic ways. How, then, can one take seriously the claim that the term designates the same entity throughout? Taking that same term as his focus and tracing its career up to 1925 in exhaustive detail, Arabatzis shows how attention to historical twists and turns can help to illuminate the slippery notion of meaning in ways that allow the realist to respond.”
C.A. Hooker | Australian Physics
""[The book] patiently and clearly, and sometimes eloquently, takes the reader through tyhe complex story that . . . is much more interesting and informative than the laundered potted history of  'achievements' typically served up to students. It remains always alive to the nature and significance of the issues at play. . . . For a practising physicist it should be a pleasure to read, and for the serious physics student it provides a valuable introduction to the subject."
Joan Lisa Bromberg | Historical Studies in the Physical and Biological Sciences
"A rich blend of philosophy and history of science. . . . Arabzatis' writing is of exemplary clarity."
Dennis Rouvray | Chemistry World
"The author of this thought-provoking work is to be congratulated both for challenging some of our most cherished assumptions and for reminding us that the world of chemistry is not nearly as cut and dried as most chemists would have us believe."
Miles MacLeod | Studies in History and Philosohy of Modern Physics
"[Arabatzis] provides a valuable and informative history of the electron and the development of its representation."
Mary Jo Nye | Ambix
"A rich and innovative book in the history and philosophy of science, in which [the author] provides an excellent technical analysis of the evolving identity of the electron among physicists and chemists. . . . Arabatzis's history is embedded within a rich philosophical framework in which he asks questions about the nature of scientific discovery, meaning and reference in scientific theory, and the support given to scientific realism or anti-realism by this historical case study."
