What is this?
A growing network of micro-tutorials. Each node teaches one concept — with interactive visualisations, mathematics, and worked examples. Nodes link to their prerequisites, so you can always go deeper or skip ahead based on what you already know.
81 nodes so far, covering probability, statistics, number theory, algebra, and orbital mechanics.

The Road to the Quintic
From permutations to why there’s no formula for degree 5 — the most beautiful dead end in mathematics.
How Rockets Reach Mars
From gravity to gravity assists — the physics of getting from here to there.
From Bayes to Topic Models
Probability, Bayesian updating, Dirichlet distributions, and LDA — the statistical backbone of text mining.
The Road to Maxwell
From scalar fields to electromagnetic waves — how four equations explain light, radio, and the fabric of reality.
The Stars Decoded
How astronomers measure what’s out there — brightness, distance, temperature, and the diagram that reveals a star’s destiny.
