Lost at Sea by the Numbers
The Brutal Mathematics of Survival and Navigation

About this book:

The ocean doesn't negotiate. It calculates. Every mile drifted, every degree of error, every calorie burned, every hour in freezing water—survival at sea is governed by ruthless equations that have decided life and death for centuries. *Lost at Sea by the Numbers* strips away the romance of maritime lore to reveal the cold, beautiful machinery underneath: the trigonometry that hides land behind the horizon, the exponential physics that birth rogue waves from calm swells, the osmotic arithmetic that makes drinking seawater a death sentence, the probability grids that determine whether a search plane ever finds you.

From the *Méduse* raft to modern search-and-rescue algorithms, this book maps the hidden geometry of disaster across twenty-five chapters. You'll learn why a single degree of compass error compounds into miles of displacement, how the Beaufort scale translates wind into kinetic violence, why scurvy follows a predictable depletion curve, and how the square-root relationship between height and vision meant the difference between rescue and oblivion for castaways in a six-foot dinghy. Historical catastrophe meets modern modeling in a narrative that reads like a thriller written by physics itself.

Whether you're a navigator, a historian, a survivalist, or simply someone who's ever stared at the horizon and wondered what lies beyond the curve, this is your primer on the mathematics that the ocean enforces—and the slender margins where human ingenuity beats the odds. The sea keeps its ledger in numbers. This book teaches you how to read it.
