Until now the theory of infinite series in general has been very badly grounded. One applies all the operations to infinite series as if they were finite; but is that permissible? I think not. Where is it demonstrated that one obtains the differential of an infinite series by taking the differential of each term? Nothing is easier than to give instances where this is not so.

Niels Henrik Abel

But just as much as it is easy to find the differential [derivative] of a given quantity, so it is difficult to find the integral of a given differential. Moreover, sometimes we cannot say with certainty whether the integral of a given quantity can be found or not.

Johann Bernoulli

In my free time I do differential and integral calculus.

Karl Marx

We have the only cookbook in the world that has partial differential equations in it.

Nathan Myhrvold

All life evolves by the differential survival of replicating entities.

Richard Dawkins

Science is a differential equation. Religion is a boundary condition.

Alan Turing

If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.
