The extent of intercourse, and of mutual assistance, between men of science and men of practice, the practical knowledge of scientific men, and the scientific knowledge of practical men, have been for some time steadily increasing; and that combination and harmony of theoretical and practical knowledge—that skill in the application of scientific principles to practical purposes, which in former times was confined to a few remarkable individuals, now tends to become more generally diffused.
"On the Harmony of Theory and Practice in Mechanics" (Jan. 3, 1856)
“Democracy is beautiful in theory; in practice it is a fallacy. You in America will see that some day.”

2013, Commencement Address at Ohio State University (May 2013)
Context: I don’t pretend to have all the answers. And I’m not going to offer some grand theory – not when it’s a beautiful day and you’ve got some celebrating to do. I’m not going to get partisan, either, because that’s not what citizenship is about. In fact, I am asking the same thing of you that President Bush did when he spoke at this commencement in 2002: “America needs more than taxpayers, spectators, and occasional voters,” he said. “America needs full-time citizens.”
And as graduates from a university whose motto is “Education for Citizenship,” that’s what your country expects of you. So briefly, I will ask you for two things: to participate, and to persevere.
After all, your democracy does not function without your active participation. At a bare minimum, that means voting, eagerly and often. It means knowing who’s been elected to make decisions on your behalf, what they believe in, and whether or not they deliver. If they don’t represent you the way you want, or conduct themselves the way you expect – if they put special interests above your own – you’ve got to let them know that’s not okay. And if they let you down, there’s a built-in day in November where you can really let them know that’s not okay.
