Templates, labs, publication tools, and guided paths for writing, computing, animating, and sharing mathematics.
Move by task instead of wading through long blocks of text: typeset a note, run an experiment, animate an idea, or turn it into an Invariant Letters post.
Four short paths built around the main kinds of work people do on the platform.
Start from ready-made sheets, notes, and slides, then use the LaTeX Lab to practise formulas, full documents, proofs, and clean mathematical writing.
Use Python, Mathematica, Maple, and SageMath to test ideas, check calculations, visualise patterns, and build short mathematics projects.
Turn graphs, transformations, and stepwise arguments into structured animations that make ideas easier to present and easier to follow.
Read expository notes, problem write-ups, essays, interviews, and announcements, or move into Letters Studio to draft your own post with text, LaTeX, and images.
Direct links for when you already know where you want to go.
Read what has been published, or move straight into writing.
