Summary

Fan Cools Air explores the surprisingly significant history and science behind the humble hand fan, revealing its enduring role in personal cooling across millennia. Far from being a simple object, the book argues that the hand fan represents an elegant, energy-efficient solution for climate control, dating back to ancient civilizations like Egypt and China, where fans held cultural and religious importance. The book uniquely bridges historical context with scientific analysis, enhanced with computational fluid dynamics simulations, to quantify the cooling effect.

The book begins by explaining the physics of evaporative cooling and convection, then transitions into a historical survey, charting the evolution of fan design and materials from simple palm leaves to intricate silk creations. Case studies illustrate how artisans adapted designs to optimize airflow, influenced by cultural exchange and trade. One intriguing insight is how fan designs from different eras reflect a deep understanding of thermodynamics and fluid dynamics, principles that are still relevant today.

In its concluding chapters, Fan Cools Air presents a scientific analysis of fan performance, using experimental data to support their utility. The book adopts a narrative non-fiction style, blending accessible scientific explanations with engaging historical anecdotes. It progresses from foundational physics to historical significance, then to modern applications and future potential, offering a comprehensive understanding of this often-overlooked technology and its potential for sustainable cooling.

Friction - Why we're paying...

Eliot Mannoia

Why the life we made easier still feels hard to live
"Eliot Mannoia asks a quiet yet unsettling question: what makes us human in a world where life no longer presents us with challenges?" — Prof. Dr. Sabine T. Köszegi, Chair of the UNESCO Advisory Board on AI Ethics, Austria
We take the escalator all day, then pay a gym to climb its stairs. We download meditation apps to recover the stillness our devices helped erode. We swipe for connection in cities packed with people. A multi-trillion-dollar wellness industry now sells back the effort, focus, and texture that ordinary life once gave us for free.
In Friction, Eliot Mannoia names a defining contradiction of modern life: we pay once for the technologies that remove friction, and again for the products and services that sell it back to us.
Drawing on observations from London to Tokyo to São Paulo, Mannoia introduces the idea of Artificial Hardship: the deliberate reintroduction of challenge, effort, and presence into lives made too frictionless. He connects the dots between the wellness boom, rising loneliness, and our growing hunger for meaning, depth, and human contact.
Friction is not anti-technology. It is a deeply researched, practical guide for living well with progress without losing the parts of ourselves that convenience cannot replace.
Inside, you’ll find:A close look at the impact of technology on our next generationThe Human Curve: why the winding path matters more than the straight oneThe Friction Compass: a practical tool for deciding when to add effort and when to remove itStrange Symmetry: how humans grow more efficient and machines grow more emotionally fluent, and where they meet
A book for anyone who senses that something essential is being smoothed away.
For readers of Stolen Focus, Four Thousand Weeks, Dopamine Nation, and How to Do Nothing.

War to the Knife - Bleeding...

Thomas Goodrich

This history shines a light on America’s “first civil war”: the bloody conflict in Kansas Territory between abolitionists and proslavery extremists. Long before the secession crisis at Fort Sumter ignited the War between the States, men fought and died on the prairies of Kansas over the incendiary issue of slavery. The bitter conflict was described in the Atchison Squatter Sovereign newspaper as “war to the knife and knife to the hilt.”  In 1854 a shooting war developed between proslavery men from Missouri and free-staters in Kansas over control of the territory. The prize was whether Kansas would become a slave or a free state when admitted to the Union, a question that could decide the balance of power in Washington.  War to the Knife is an absorbing account of this bloody episode in our nation's past, told in the unforgettable words of the men and women involved: Robert E. Lee, William Tecumseh Sherman, Sara Robinson, Jeb Stuart, Abraham Lincoln, William F. Cody, and John Brown—the abolitionist who was hailed by some as a prophet, and denounced as a madman by others.
