Summary

Winner, 2025 Choice Outstanding Academic Title

On the surface of the Sun, spots appear and fade in a predictable cycle, like a great clock in the sky. In medieval Russia, China, and Korea, monks and court astronomers recorded the appearance of these dark shapes, interpreting them as omens of things to come. In Western Europe, by contrast, where a cosmology originating with Aristotle prevailed, the Sun was regarded as part of the unchanging celestial realm, and it took observations thr…

Critics Review

The Clock in the Sun is a one-of-a-kind history of our understanding of the Sun—and how it has often defied authorities’ predictions. Sokolsky beautifully traces this story over nearly a thousand years and across the world, ranging from observations of sunspots through clouds and colorful wisps during solar eclipses to the Nobel Prize-winning research that has led us to believe we finally grasp how the Sun functions. – Peter L. Biermann, Max Planck Institute for Radio Astronomy
Pierre Sokolsky, a pioneer in observing cosmic rays by the streak of fluorescence they leave in the atmosphere, is fascinated with sunspots. In The Clock in the Sun, he takes us on a grand tour covering the history of astronomy and the physics of the sun, with sunspots as a central theme. The result is a book suitable for general readers, and for specialists, a weekend of fascinating reading. – Francis Halzen, Vilas Research Professor and Gregory Breit Professor, University of Wisconsin–Madison
The Clock in the Sun rekindles in me a spark of what my ancestors must have felt when they worshiped the Sun. Sokolsky methodically reconstructs the mystery and history of sunspots and reignites curiosity for our phenomenal solar timekeeper. – Jamie Zvirzdin, author of Subatomic Writing: Six Fundamental Lessons to Make Language Matter
The Clock in the Sun catches the pulse of our favorite star as well as that of our intellectual history with it. Interested readers of all levels will have something to learn and enjoy. * Open Letters Review *
Offers fascinating reading. [The Clock in the Sun] brings readers up to date on the current solar model, while informing them of the rich history of solar astronomy. * Mark Lardas, Ricochet *
Provides a unique look at world history as seen through the lens of solar astronomy. Mr. Sokolsky does a splendid job. * The Wall Street Journal *
The Clock in the Sun is a fascinating account of humanity’s relationship with the sun. Sokolsky weaves a compelling yarn that spans over 1,000 years of astronomical history, from humanity’s worship of the sun in ancient times to the constellation of spacecraft that monitor it 24⁄7 today. Rich in both history and science, this is an engaging, thought-provoking read. Highly recommended. * T.D. Oswalt, Choice Reviews *
Sokolsky provides a comprehensive history of the science of the sun from antiquity to the present. In the process, he offers portraits of the people responsible for these discoveries and illuminates the ways in which ideas travel and evolve between cultures and across time. * University of Chicago Magazine *
