Publisher's Overview
Time is an elusive "thing" whose existence is undeniable—something everyone talks about yet no one has ever seen. We experience events within time through sight, sound, touch, and taste, but never time itself. Against all expectations, Chronos is a fugitive, a chameleon hiding behind our habits of language and perception. To outsmart him, we must strip away his layers bit by bit, laying him bare to distinguish him from his most tangible effects: duration, memory, movement, becoming, velocity, and repetition. For clocks do not necessarily measure time. Time is always present even when we say it slips away, and it exists independently of whatever happens, transforms, ages, and dies. Today, physics offers the most daring and unsettling perspective on time. From Galileo to Einstein, and from antimatter to superstrings, physics has continuously deepened the inquiry, opening up dizzying possibilities: Did time precede the Universe? How did it start ticking? Could it reverse its course? Could it pause and then resume? Could multiple times exist simultaneously? Ultimately, time may no longer resemble itself at all.
Author Biography
A physicist at the French Alternative Energies and Atomic Energy Commission (CEA), a faculty member at École Centrale, and a holder of a PhD in the philosophy of science, Étienne Klein is a leading specialist on the concept of time in physics. His published works include: Conversations avec le Sphinx. Les paradoxes en physique (Albin Michel, 1991; Le Livre de poche, 1994); L'Atome au pied du mur et autres nouvelles (Le Pommier, 2000); L'Unité de la physique (PUF, 2000); and Petit voyage dans le monde des quanta (Flammarion, 2004). He received the "La science se livre" prize in 2004 for The Tactics of Chronos.
The study of time has long occupied a central position in both natural philosophy and modern physics, bridging the gap between human experience and the mathematical models used to describe the universe. This work distinguishes between the subjective sensation of duration and the properties of physical phenomena, engaging with the tradition that seeks to define time independently of the events that occur within it. It examines how scientific inquiry, from classical mechanics to contemporary theories, addresses temporal progression and the potential for non-linear dynamics.
This text situates itself within the broader discourse on the philosophy of science, where the nature of change, movement, and becoming remains a subject of debate. By examining the limitations of mechanical measurement, the author explores how language and perception relate to the nature of temporal existence. The discussion highlights how physics introduces questions regarding the origins of the universe and the possibility of multiple, simultaneous temporal frameworks. Readers interested in the intersection of theoretical physics and the conceptual analysis of time may find this volume relevant to their inquiries.
