Books by Jonathan Kendall

The Wall at Two

Seeing Why a Number Keeps a Secret

N gives you the circle. It withholds the angle. A visual way into why factoring is hard.

Preservation and Horizons

On Difficulty, Verification, and Structural Limits

What it costs to check an answer, what it costs to find one, and where the structural limits sit.

The Rooms That Hold Us

Storms, Survival, and the Gatherings That Remake a People

How storms change us for good, and how small gatherings turn private survival into the remaking of a people.

The Big Book of Prime Secrets

How Numbers Keep Secrets, and Why No One Has Cracked Them

Four books in one volume: The Wall at Two, Preservation and Horizons, The Real Gatekeeper and Light Through the Holes.

The Free Machine, Book One

How Computers Work and Who Fought to Control Them

A computer built from the idea up, then followed into the world: Bell Labs, phone phreaks, Unix, GNU, Linux and AI.

The Free Machine, Book Two

Daily Driving Linux, Building With AI, and Wiring Your Own Computer

The machine in your hands: live on Linux, build software with an AI partner, run a Pi radio station, wire a light show.

Light Through the Holes

Sieves, Strikes, and the Price of Seeing Primes

A history of the sieve, from Eratosthenes' counting board to machines that listened for light.

The Garden That Computes

Computers Grown, Not Built

Nanites, crops, cells and seeds: what a living machine can do, and where the toll still catches it.

The Real Gatekeeper
