Famous quotes containing the words test and/or mode:
“Whenever a true theory appears, it will be its own evidence. Its test is, that it will explain all phenomena.”
—Ralph Waldo Emerson (1803–1882)
“If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.”
—Henry Brooks Adams (1838–1918)
