Twentieth-century school systems print the theorem-name as a Western-origin badge

Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute. A 1950 theorem-badge is not a Croton proof. In the causal graph this event strengthens Political Polarization, a driver that weakens Having a say in government — a worsening welfare path.

Read the full account

Polarising origin-myth is the path. He did not write a 1950 syllabus.

Context

Split classroom access. This stores the badge.

Pythagoras is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

Why it matters

A 1950 theorem-badge is not a Croton proof.

Who was responsible
