Sinopse

"The Sun Dial" explores the history and science of sundials, revealing their crucial role in ancient timekeeping and their influence on modern time measurement. For millennia, sundials dictated daily life, reflecting humanity's ingenuity in harnessing the sun's power. These devices weren't just tools; they were integral to social, religious, and economic practices across cultures, influencing everything from agricultural schedules to architectural designs. The book journeys from the earliest sundial iterations in ancient civilizations to the sophisticated designs of the Renaissance, highlighting regional variations and technological advancements. It examines the scientific principles underpinning their operation, such as the Earth's rotation and the sun's position, and explores how these principles allowed for surprisingly accurate time measurement. One intriguing fact is how sundials, despite their simplicity, required a practical understanding of astronomy and mathematics for accurate construction. Structured chronologically and thematically, "The Sun Dial" begins with basic concepts of solar time and progresses through historical development in various cultures. Major sections focus on sundials in ancient Egypt, Greece, and Rome, their evolution during the medieval period and the Renaissance. It culminates by discussing their decline with mechanical clocks while emphasizing their continuing role as decorative and educational objects, offering a comprehensive yet accessible account bridging scientific analysis and historical narrative.

The Master Builder - How the New...

Alfonso Martinez Arias

"An ingenious argument" (Kirkus) for a "novel thesis" (Publishers Weekly) that cells, not DNA, hold the key to understanding life's past and present 
 
 
 
What defines who we are? For decades, the answer has seemed obvious: our genes, the "blueprint of life." In The Master Builder, biologist Alfonso Martinez Arias argues we've been missing the bigger picture. It's not our genes that define who we are, but our cells. While genes are important, nothing in our DNA explains why the heart is on the left side of the body, how many fingers we have, or even how our cells manage to reproduce. Drawing on new research from his own lab and others, Martinez Arias reveals that we are composed of a thrillingly intricate, constantly moving symphony of cells. Both their long lineage—stretching back to the very first cell—and their intricate interactions within our bodies today make us who we are. 
 
 
 
Engaging and ambitious, The Master Builder will transform your understanding of our past, present, and future—as individuals and as a species.
