Sinopsis

Hidden Sea Signals explores the fascinating history and technology of lighthouses, revealing how these beacons served as vital pre-digital communication hubs for maritime navigation and global commerce. Far from being simple structures, lighthouses housed sophisticated systems employing light, fog, and radio signals, all managed by dedicated keepers. The book highlights how the evolution of lighthouse technology, from basic coal fires to advanced Fresnel lenses, dramatically improved signal precision and reliability, crucial for maritime safety.

 
The book progresses by first detailing the technological foundations of lighthouses, then examining the lives and work of the keepers, and finally analyzing case studies of maritime incidents where signaling played a critical role. By drawing on archival records, personal journals, and oral histories, Hidden Sea Signals paints a vivid picture of this bygone era.

 
The book uniquely emphasizes how lighthouse communication formed a sophisticated technological network, essential for maritime safety and global trade, long before modern digital systems.

  • The Curious History of the Heart - A Cultural and Scientific Journey - cover

    The Curious History of the Heart...

    For much of recorded history, people considered the heart to be the most important organ in the body. In cultures around the world, the heart—not the brain—was believed to be the location of intelligence, memory, emotion, and the soul. Over time, views on the purpose of the heart have transformed. Modern medicine and science dismissed what was once the king of the organs as a mere blood pump subservient to the brain, yet the heart remains a potent symbol of love and health and an important part of our cultural iconography. 
     
     
     
    This book traces the evolution of our understanding of the heart from the dawn of civilization to the present. Vincent M. Figueredo—an accomplished cardiologist and expert on the history of the human heart—explores the role and significance of the heart in art, culture, religion, philosophy, and science across time and place. He examines how the heart really works, its many meanings in our emotional and daily lives, and what cutting-edge science is teaching us about this remarkable organ. Figueredo considers the science of heart disease, recent advancements in heart therapies, and what the future may hold. He highlights the emerging field of neurocardiology, which has found evidence of a "heart-brain connection" in mental and physical health, suggesting that ancient views hold more truth than moderns suspect.

    *PULITZER PRIZE FINALIST*A sweeping history of the inventors, inventions, and innovations that together created modern America.A stunning, wide-ranging history from one of the foremost historians of technology of our age, American Genesis tells the sweeping story of the technological revolution that made modern America. Unlike other histories of technology, which focus on particular inventions like the light bulb or the automobile, American Genesis makes these inventions characters in a broad chronicle, both shaped by and shaping a culture. By weaving scientific and technological advancement into other cultural trends, and bringing in fascinating characters like Edison, Ford, and Frederick Taylor, Hughes demonstrates here the myriad ways in which the two are inexorably linked, and in a new preface, he recounts his earlier missteps in predicting the future of technology and follows its move into the information age.
