Is all our Life, then but a dream Seen faintly in the golden gleam Athwart Time's dark resistless stream?
Mighty is geometry; joined with art, resistless.
'Nature is conquered by obedience' - and her resistless energies are at our bidding, as soon as we, by knowledge, work with them and not against them. We can choose out of her boundless stores the forces that serve our purpose in momentum, in direction, and so on, and their very invariability becomes the guarantee of our success.
