We are in the beginning of the greatest change that humanity has ever undergone. There is no shock, no epoch-making incident, but then there is no shock at a cloudy daybreak. At no point can we say, here it commences, now, last minute was night and this is morning. But insensibly we are in the day. What we can see and imagine gives us a measure and gives us faith for what surpasses the imagination.
—H. G. Wells, “The Discovery of the Future”, lecture delivered at the Royal Institution in London, 1902, as quoted by Freeman Dyson in Infinite in All Directions
我们正处在人类所经历的最大变化的开始。没有震撼，没有划时代的事件，但是在多云的黎明中没有震动。我们不能说，现在开始，现在，最后一分钟是夜晚，这是早晨。但不知不觉，我们在白天。我们能看到和想象的东西给了我们一个度量，给了我们超越想象的信心。
- H. G. Wells，《未来的发现》，在1902伦敦皇家学会发表的演讲，由戴森无限地引用在四面八方。（谷歌翻译仅供参考）
