From the derivative to the Fourier transform — the structures and patterns that underlie everything else.

Motion, waves, relativity and the quantum world — the rules the universe actually runs on.

Atoms, bonds and reactions — how matter is built and how it rearranges.

Life from the molecule up — the code, the machinery that reads it, and the cells it builds.

The machinery of a working planet — its shifting crust, its circulating air and ocean, and the budgets that set its temperature.

The universe at large scale — how stars live and forge the elements, how we find other worlds, and how space itself is expanding.

Algorithms, complexity and the limits of computation — how machines solve problems, and what they provably cannot.

How the internet actually works — the chain of inventions, each one solving the limit the last hit, that carries a request from your browser to a server and back.

The body as a system to measure and manage — its signals, its chemistry, and the tools that see inside it.
