Notation Is Compressed Language

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Formal notation is compressed language: every symbol is a name somebody chose, and every formula is a sentence that can be read aloud in words.

Show

"b to the power d" is three characters carrying a nineteen-word sentence about choices and steps.

Watch for

The standing rule: never let a formula pass unread — say its sentence before moving on.
