About Babel Bible

A self-study curriculum that takes a learner from foundations to graduate-level mastery across the sciences and humanities — math, physics, chemistry, biology, philosophy, language, and the social world. Every concept exists at three depths in a single source document; the site filters what you see.

The three tiers

Pick a tier in the header. Each unit packs all three depths into one source file; the tier toggle changes which sections render.

  • Beginner — intuition, visuals, worked examples with everyday numbers. Math/physics anchors: 3Blue1Brown, Strogatz Infinite Powers. Other domains use their own field-canonical entry points. Endpoint: scientific and cultural literacy.
  • Intermediate — definitions, proofs, exercises, scaffolded Lean puzzles where applicable. Math/physics anchors: Axler Linear Algebra Done Right, Apostol Calculus, Griffiths Electrodynamics. Endpoint: undergrad-textbook mastery.
  • Master — full proofs, primary literature, hard problems, full Lean formalisation where Mathlib covers. Math/physics anchors: Lang Algebra, Hartshorne, Bott-Tu, Lawson-Michelsohn, Weinberg. Endpoint: graduate research readiness.

How units work

A unit is one concept — one theorem cluster, one technique. All three tiers live in the same markdown source. Section markers ([Beginner], [Intermediate+], [Master]) gate visibility; the toggle in the header is the user-facing switch.

Cross-references like [04.04.03] link to other units at your current tier. Citations like [ref: source locator] open a side panel with full source metadata. Mathlib-formalisation status is declared per unit and aggregated on the Lean page below.

v0.1 is apex-first: Master-tier graduate content seeded at the top of the curriculum first (spin geometry, QFT, algebraic topology). Beginner and Intermediate tiers exist as place-holders for apex units; they fill in as the prerequisite chain reaches them.

If you arrived hoping for accessible introductions to graduate-level material, you are early. v1 is the right time to come back. v0.x is for graduate readers who want a single cross-linked reference.

Where the material comes from

Every Master-tier unit cites primary literature with page references. Where a published source isn't available we cite first-principles reasoning. The booklist below is the canonical anchor set; the connections registry is the cross-unit synthesis layer.

Babel Bible ships through automated quality gates and a human reviewer pipeline. The production plan, reviewer protocol, and house-style specs are all public.
