Make the idea visible
Every lesson names the example, variable, graph, or output that carries the idea.
Lab0 / about
Learning gets clearer
when it can run.
Lab0 is a learning platform for technical subjects. We pair plain-language lessons with browser practice so people can test an idea while it is still fresh.

The gap is rarely information. It is the moment of trying.
A learner can read a definition and still not know what to do with it. Lab0 turns that next step into part of the lesson: change something, run it, inspect the result, and explain what moved.
Give the learner a move
A useful prompt asks for one meaningful change so practice starts with a decision.
Keep the evidence
Attempts and explanations stay close to the work, not in a separate reporting layer.
Built for different starting points
Independent learners
Follow a course, save your progress, and return to the exact idea you were working through.
Curious experimenters
Open a bounded lab when you have one behavior, equation, or output you want to inspect.
Teaching teams
Give classes a shared practical starting point and see the evidence that comes from doing.
