Learn anything. From the ground up.
Two complete curricula built from first principles — one for living on and from the land, one for understanding the world beneath it. Free. Sequenced. No university required.
Most of what matters — how to grow food, how electricity works, how to read a topo map, how to think clearly, how to write precisely, how history actually happened — is freely available to anyone willing to learn it in the right order.
Brainfolds is two complete curricula built to teach those things properly, from the ground up, one chapter at a time. No tuition. No prerequisites. No gatekeeping. Just the knowledge, sequenced so each chapter unlocks the next.
Start wherever you are. Go as deep as you want.
Reading is not learning. These ten practices are what separate people who finish a curriculum and own the knowledge from people who finish it and forget it within a month.
When a chapter has a diagram, close the page and draw it from memory. You don't need to be an artist — a rough sketch with labels forces your brain to reconstruct the structure rather than passively recognise it. A bad drawing you made yourself teaches more than a perfect one you looked at.
After each chapter, ask: where else have I seen this? The Casparian strip in botany is the same idea as a checkpoint at a border. Turgor pressure is the same idea as a pressurised hose. Mycorrhizal networks work the same way as a supply chain. The connections are real — finding them is how knowledge becomes a web instead of a list.
Explain what you just read to another person, to a pet, to an empty room. The moment you try to put something into spoken words, every gap in your understanding becomes immediately obvious. You cannot fake fluency out loud the way you can fake it while reading. If you stumble, that is the thing to go back and reread.
Use the chapter quizzes — but also make your own. Cover the page and recite the key points. Come back to a chapter three days later and test yourself before rereading. Testing yourself when you're likely to fail is more effective than rereading when you'll get everything right. Struggle during practice is not a sign of failure — it is how memory forms.
Every Self Sufficiency chapter is written to be used outdoors. After reading about soil texture, go do the ribbon test on your soil. After reading about leaf venation, identify the pattern on five plants outside your door. After reading about mycorrhizal networks, dig up a root and look for the white threads. The chapter prepares you to see something. Go see it.
Come back to every chapter — but time your returns deliberately. The schedule that works: quiz yourself the same day you read it, again the next morning before reading anything new, again after 3 days, again after 1 week, again after 1 month. Each return starts with a self-test before you reopen the page. If you answer correctly, the gap before the next return doubles. If you struggle, you come back sooner. The gaps are not wasted time — they are when consolidation happens. A chapter revisited five times across a month is owned. A chapter read five times in one afternoon is not.
Interleaving is not reading randomly — it is deliberately mixing subjects that are genuinely connected to each other. The connection is the point. Read Botany Ch 3 (Roots), then Soil Science Ch 8 (Mycorrhizal Fungi), then back to Botany Ch 4 (Stems). Those three chapters reinforce each other — you just learned what roots do, now you learn what lives on them, then the transport system that carries what they gathered. Reading them in separate blocks months apart means each chapter starts cold. Reading them together means each one builds on real context you just laid down. The Connections section at the end of every chapter tells you which chapters in other curricula are worth visiting now rather than later.
Read the chapter in the evening, do the quiz, then stop. Don't cram more in after. Memory consolidation happens during deep sleep — the chapter you read the night before is measurably better retained the next morning than it was when you closed the page. This is not a metaphor. The brain replays and reorganises new information during sleep. Staying up late to read one more chapter actively undermines the chapters you already read.
Instead of writing down what the chapter said, write down questions the chapter answers. "What prevents roots from absorbing toxins indiscriminately?" is more useful than "Casparian strip = watertight seal." When you come back to review, you have a question bank — test yourself by answering before you check. Questions force you to understand the structure of the knowledge, not just the surface. Notes tell you what you read. Questions tell you whether you understood it.
After finishing a chapter, close it and write a summary from memory in four to six sentences. Not a transcript — a compression. What were the two or three things that actually mattered? What would you tell someone who had five minutes to understand this topic? If you can't write the summary without reopening the chapter, you haven't learned it yet — go back, find what you missed, and try again. The summary is the test.
Each one built chapter by chapter, section by section, from first principles
A Complete Curriculum for Self-Sufficient Living
Everything a person needs to live productively on and from the land — from botany, soil science, and water harvesting through blacksmithing, food preservation, natural building, celestial navigation, veterinary basics, and end of life on the land. Rooted in Texas. Universal in principle.
A Personal Curriculum for Lifelong Learning
21 subjects in 5 tiers — from English grammar, mathematics, and critical thinking through geology, physics, anatomy, programming, cybersecurity, electrical engineering, and political philosophy. Sequenced so each chapter builds on the last. No prerequisites assumed at Tier 1.
Every subject starts at the actual beginning. No assumed prior knowledge. Each chapter unlocks the next in a deliberate sequence.
No subscriptions. No paywalls. No accounts. Download it, share it, use it offline. This knowledge belongs to you.
Plain HTML files that work in any browser, online or off. No platform dependency. Still readable in 30 years.
Not a surface overview. Each chapter earns the next one. By the end of each curriculum you actually know the subject.
Written for people who want to understand, not just to pass a test. The why matters as much as the how.
Self Sufficiency is anchored in Texas land and ecology. The principles apply everywhere — the examples are real and specific.
