The Lab
Where new ideas first appear.
Eureka is a long project. Here is everything that is live, being built, or still being explored.
Switchcraft
The computer, from the electron up: 21 interactive chapters with a circuit sandbox, a CPU you can step through, and branches on graphics, AI, touchscreens, networks and voice.
Enginecraft
51 chapters on engines and energy, each with its history, the physics behind it, and a build you can do at home.
Smarter Stronger coaching
One-to-one coaching that trains the thinking behind maths and science, with a free diagnostic that shows which mental operation is holding a student back.
Cosmocraft
22 chapters on the universe, from measuring the Earth with a shadow to the Big Bang and the far future, with immersive labs, an atlas of every kind of object and a Map of Everything.
Biocraft
Biology from the ground up: what makes something alive, atoms and water, the molecules of life and the cell, with labs you can play and experiments for the kitchen. The first 4 chapters are live, more every month.
LUMO, your guide
The Eureka firefly, animated live in your browser, to point the way through each course and celebrate the moment an idea clicks.
One account for every world
Sign in once and find your progress in every course in one place.
Mathematics, physics, chemistry
More worlds built the same way: from intuition and first principles to the frontier of each field.
More languages
Arabic and more, so that understanding is never limited by language.
