Science: From Matter to Cosmos

A guided self-education in science, ordered by scale. You begin with how science knows anything at all, then climb from atoms to forces, from spacetime to the planet, from the first cells to the brain, and finish with the universe as a whole. Each module hands the next its subject, so that by the end the periodic table, natural selection and the expanding cosmos feel like chapters of one story rather than separate subjects. The promise is not a physics degree; it is being able to read a science headline and know where it sits, what would count as evidence for it, and what it would change if true.

Module 1

How Science Knows

Before any particular science, the shape of the whole and the method that holds it together. Three books on what scientists actually do, how the enterprise polices itself, and why not knowing is the engine rather than the embarrassment.

Core · Book

A Short History of Nearly Everything

Bill Bryson

The whole of science in one volume, told by an outsider who asked scientists to explain themselves. Read first so that every later module has a place on a map you already hold.

Ignorance: How It Drives Science

Stuart Firestein

A Columbia neuroscientist on the working truth that science is driven by good questions rather than settled answers. Short, and a corrective to the textbook picture of accumulated fact.

Matter and Its Building Blocks

Everything is made of atoms. Feynman states the idea in a page; Kean and Le Couteur show what follows from it, element by element and molecule by molecule.

Core · Book

Six Easy Pieces

Richard Feynman

Six chapters lifted from the Feynman Lectures, beginning with the single sentence Feynman thought contained the most information: all things are made of atoms. The best entry into physics ever written.

The Disappearing Spoon

Sam Kean

The periodic table told as a set of stories, one per element, from the gallium spoon that melts in tea to the politics of the transuranics. Chemistry as history rather than as a chart to memorise.
