Is MathWorld available in languages other than English?
Unfortunately, the task of translating the entire site is too large to be undertaken at this time. The contents of MathWorld are the equivalent of thousands of printed pages, and so would require a vast effort to translate. Such a task would also be made more difficult by the technical nature of the material. Although the MathWorld team has received requests for translations into French, German, Hebrew, Italian, Persian, Portuguese, Russian, and Spanish, at the moment there are no plans for creating them.
