- Nature was widely believed to be unstable and capricious, with monstrous births from union between species, and spontaneous generation of life. 人们普遍认为自然是不稳定和反复无常的，种间结合产生出畸形怪胎，生命是自然发生的。
- In 1860 Louis Pasteur performed experiments that eventually disproved “spontaneous generation,” the idea that life continually arose from nonliving things. 1860年，路易斯巴斯德做了个实验，最终反驳了“自然发生说”，这一说认为生命源源不断于无生命的物体。
- If we could document the spontaneous generation of just one complex life-form from inanimate matter, then at least a few creatures seen in the fossil record might have originated this way. 要是复杂生物可以从没有生命的物质自然发生，我们只要提出证据，哪怕只是一件，那麽我们就可以推论，化石记录上至少有一些生物也许就是以同样的方式形成的。
- Noise is usually measured in volts relative to the generated signal. 噪声通常以其与正常信号的伏特比来标定其大小。
