THE RECORD
What changed
The UN adopted the UDHR; Shannon mathematically defined information, channel capacity and noise.
EVIDENCE
What remains
Resolution 217 A and drafting records, plus Shannon's 1948 paper and Bell Labs materials, survive.
WHY IT MATTERS
Why it matters
One supplied a language of universal dignity; the other a language for digital communication.
OPEN QUESTION
Where interpretation begins
The declaration is not itself a treaty and implementation varies; Shannon information does not measure meaning or truth.
