For example, the mere fact that we can describe both the behavior of a system of gravitating masses and the operation of an electric circuit by means of Lagrange's equations does not mean that we have achieved a common explanation of the behavior of both or that we have “unified” gravitation and electricity in any physically interesting sense.

Euler's equation treated fluids as continua or fields, whereas Lagrange's formulation treats them as discrete particles (see Emanuel 2000, 8).

Lagrange's treatise is old-fashioned, but readable, Newton's treatise is “immortal,” but antiquarian, and very difficult.

You had better leave the country, for I can surmise what agency _you_ had in the affair of Lagrange's disappearance; but as you were the tool of others, I stoop not to molest you.

At Lagrange's name, Therese recalled the flaming comet announced by the savant, and said to herself, with mocking sadness, that it was time for that comet to put an end to the world and take her out of her trouble.
