A Scheme of Heaven

The History of Astrology and the Search for Our Destiny in Data

Alexander Boxer

In *A Scheme of Heaven*, Alexander Boxer examines the history and science of astrology, revealing it as a vast technological project that foreshadowed our data-driven world. He explores classical texts to expose astrology's underlying scientific and mathematical framework, highlighting its role as the ancient world's most ambitious applied mathematics problem. By comparing ancient astrological methods with modern data science, Boxer illustrates how both fields share a common goal of pattern recognition.

What are the most EXTREME lifeforms on Earth, and how are they surprisingly important to study? And what is the long yet recent history of astrology, and why do we reach for it?
