"Research is the effort of the mind to comprehend relationships which no one has previously known, and in its finest exemplification it is practical as well as theoretical, trending always toward worthwhile relationships, demanding common sense as well as uncommon ability."

-- H. D. Arnold, 1925, first research director at Bell Labs
