行列式｜线性代数的本质 第6章

A 10-minute 3Blue1Brown chapter explaining the determinant as the factor by which a linear transformation scales area or volume. It builds the idea geometrically with animations before any formulas.

Why HN likes it: HN repeatedly points people to it as the clearest visual intuition for determinants, often saying it finally made the concept click.

“I have warmed up to determinants ever since I saw 3Blue1Brown give a fairly intuitive explanation for them”
