The big ideas

Shannon separated information from meaning, measuring it as reduction of uncertainty — a move that made modern communication possible and is deeply counterintuitive.

Redundancy is what makes a message survive a noisy channel, which applies to every explanation you have ever given twice.

It traces how each new medium changed what could be thought, not merely what could be sent.

Practise it — no need to have read it

Take a message you need to land. Identify what uncertainty it is meant to reduce for the recipient, and cut everything that does not.

A hint: Then add back deliberate redundancy for the part that must survive.
