Applied Chemistry

Famous quotes containing the words applied and/or chemistry:

“A propositional sign, applied and thought out, is a thought. A thought is a proposition with a sense.”
—Ludwig Wittgenstein (1889–1951)

“Science with its retorts would have put me to sleep; it was the opportunity to be ignorant that I improved. It suggested to me that there was something to be seen if one had eyes. It made a believer of me more than before. I believed that the woods were not tenantless, but choke-full of honest spirits as good as myself any day,—not an empty chamber, in which chemistry was left to work alone, but an inhabited house,—and for a few moments I enjoyed fellowship with them.”
—Henry David Thoreau (1817–1862)
