An interdisciplinary journey through history, science, and art - exploring how harmony and rhythm have shaped our understanding of the cosmos and ourselves.What do a medieval board game, a mystic dancer, a stroke survivor, and the orbit of Jupiter have in common? All are part of the long human search for harmony and rhythm - principles that have shaped music, mathematics, architecture, medicine, theology, and cosmology across millennia. Harmony and Rhythm of the Universe: Interdisciplinary Explorations from 1500 to the Present brings together physicists, astronomers, neuroscientists, mathematicians, musicians, historians, and theologians in a richly interdisciplinary dialogue. From Pythagoras and Plato to Kepler and Einstein, from Renaissance Spain to modern neuroscience, this volume traces how two deceptively simple concepts have proven endlessly generative - capable of connecting the movements of celestial bodies to the rhythms of the human heartbeat, and the proportions of a cathedral façade to the intervals of a musical scale.Rather than offering a linear history, the book demonstrates that harmony and rhythm are living, contested, and evolving ideas. Past and present speak to one another here: ancient intuitions illuminate new discoveries, and contemporary science casts fresh light on centuries-old thought.For anyone curious about the deep connections between art, science, and the human experience of the universe, this volume is an invitation to listen more carefully - to the world, and to ourselves.
