You cannot change and yet remain the same, though this is what most people want.

--Patrick J. MacDonald

Changing while remaining the same is what Algebra is all about. Identify the quality you wish to hold invariant, then find the transformations that do so. Changing things while leaving them the same in important ways is how problems are solved.

5shminux5yAn interesting quote, but isn't it basically the definition of identity? The part that remains the same while changing all the while?
