我们大概能够造出,比用一大群艄公还能使船跑得快,而且为了操纵这艘船只有一名驾驶员就足够了的机器,不借用任何畜力就能以惊人的速度奔跑的车辆,使我们用翅膀像鸟儿一样飞翔成为可能的那种机器。——弗兰西斯·培根 We could probably build a machine that would run the boat faster than a large crowd of people and that only one driver was enough to maneuver the ship, a vehicle that could run at an alarming rate without any animal power, The kind of machine we can fly with our wings like a bird. - Francis Bacon
