文明与病毒之间，只隔了一个航班的距离。
来自热带雨林的危险病毒，可在24小时内乘飞机抵达地球上的任何城市。航空线路连接了全世界的所有城市，构成网络。
埃博拉已经进入网络，开始环球旅行。
卡尔•约翰逊，埃博拉病毒的发现者之一，他在病毒探索史上是个大人物，发现并命名了地球上好几种最危险的病原体。
“大自然并不平静，我很高兴，”他这么说，“但在今天这样的日子里，咱们就当大自然很平静好了。所有怪物和猛兽都有平静的时刻。”
“扎伊尔当时发生了什么？”我问。
“我们抵达金沙萨的时候，那儿根本就是个疯人院，”他说，“我们知道那里的情况很糟糕，我们知道我们在和某种新病毒打交道。我们不知道它能不能像流感那样，通过空气中的悬浮液滴传播。假如埃博拉能轻易通过空气传播，今天的世界恐怕就大不一样了。”
“会怎么样？”
“人类会少很多。假如一种病毒与呼吸系统密切相关，那么你想控制住它就非常困难了。我心里想，假如埃博拉具备高致死率，又能通过液滴传播，那么全世界就不存在安全的地方了。与其在伦敦歌剧院被传染，还不如去爆发中心工作呢。”
“你担心那会是一次威胁整个人类的危机吗？”
他盯着我。“这话什么意思？”
“意思是一种能抹平人类的病毒。”
“唔，我想有这个可能性——当然到现在还没有出现。我并不担心那个。更有可能的是这种病毒有能力按比例减少人口。比方说百分之三十。百分之九十。”
“人类被杀死十分之九？你不担心？”
他脸上闪过一丝神秘的沉思表情。“假如一种病毒能减少一个物种的密度，那么这种病毒也许还是有用的。”
这就是大自然。仔细想一想，从河流到海洋，大自然充满了杀手。

Bill Bryson describes himself as a reluctant traveller: but even when he stays safely in his own study at home, he can't contain his curiosity about the world around him. A Short History of Nearly Everything is his quest to find out everything that has happened from the Big Bang to the rise of civilization - how we got from there, being nothing at all, to here, being us. Bill Bryson's challenge is to take subjects that normally bore the pants off most of us, like geology, chemistry and particle physics, and see if there isn't some way to render them comprehensible to people who have never thought they could be interested in science. It's not so much about what we know, as about how we know what we know. How do we know what is in the centre of the Earth, or what a black hole is, or where the continents were 600 million years ago? How did anyone ever figure these things out? On his travels through time and space, he encounters a splendid collection of astonishingly eccentric, competitive, obsessive and foolish scientists, like the painfully shy Henry Cavendish who worked out many conundrums like how much the Earth weighed, but never bothered to tell anybody about many of his findings. In the company of such extraordinary people, Bill Bryson takes us with him on the ultimate eye-opening journey, and reveals the world in a way most of us have never seen it before.

衣食住行是我们最日常的生活，看似平淡，但如果你想要更好的生活质量，那么多了解其中的技术信息，消除一些技术方面的误会，就很必要了。
穿衣打扮要了解日用化学品的性质；饮食健康要了解肠胃、细菌、食品工业；居家舒适要了解电器有多智能，环境可以怎么改造；出门在外要了解交通工具和路况——最普通的生活离不开最基础的科技。果壳网用通俗的语言为你提供这些信息：享受生活需要有技术含量。
有技术含量，生活才有质量。用科技服务生活。
