In linear algebra, the Lewis Carroll identity is an identity involving minors of a square matrix proved by Charles Lutwidge Dodgson (better known by his pseudonym Lewis Carroll), who used it in a method of numerical evaluation of matrix determinants called the Dodgson condensation. From the modern perspective, the Lewis Carroll identity expresses a straightening law in the algebra of polynomial functions of matrices.

“And would you be a poet
Before you’ve been to school?
Ah, well! I hardly thought you
So absolute a fool.
First learn to be spasmodic—
A very simple rule.
For first you write a sentence,
And then you chop it small;
Then mix the bits, and sort them out
Just as they chance to fall:
The order of the phrases makes
No difference at all.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“The “female culture” has shifted more rapidly than the “male culture”; the image of the go-get ‘em woman has yet to be fully matched by the image of the let’s take-care-of-the-kids- together man. More important, over the last thirty years, men’s underlying feelings about taking responsibility at home have changed much less than women’s feelings have changed about forging some kind of identity at work.”
—Arlie Hochschild (20th century)
