About

Pi & Planck is a daily math and physics account: one infographic a day, in English and Farsi, built from primary sources (journals, arXiv with status stated, university and observatory pages, NASA, CERN, NIST, MacTutor). Numbers are recomputed in code before they are published.

The name joins π, the constant of the circle, with Planck, the scale where known physics runs out.
