The hartaus

We print real mathematics on clothing. Each design is an exact drawing of a particular object, like a knot, a group, a curve, or a σ-algebra. We print them at the exact size they are meant to be seen, and none of it is ornament.

We describe each piece plainly, telling you exactly what it is and where it comes from. You will not find any puns or slogans here. The drawing is the design itself, and the label just names it.

The catalogue lists everything we make, and the library collects the books these objects come from.

We started this project out of pure frustration, as most math clothing relies on cheap jokes or simple symbols. We believe the mathematics deserves better than a punchline. It took months of translating textbooks into precise vectors to get this right. We print the object itself, exactly as it is, and leave it to stand on its own.
