In 2006, he left NASA to draw comics on the internet full-time, supporting himself through the sale of xkcd t-shirts, prints, posters, and books.

From the creator of the wildly popular webcomic xkcd, hilarious and informative answers to important questions you probably never thought to ask
Millions of people visit xkcd.com each week to read Randall Munroe’s iconic webcomic. His stick-figure drawings about science, technology, language, and love have an enormous, dedicated following, as do his deeply researched answers to his fans’ strangest questions.
The queries he receives range from merely odd to downright diabolical:
• What if I took a swim in a spent-nuclear-fuel pool?
• Could you build a jetpack using downward-firing machine guns?
• What if a Richter 15 earthquake hit New York City?
• Are fire tornadoes possible?
His responses are masterpieces of clarity and wit, gleefully and accurately explaining everything from the relativistic effects of a baseball pitched at near the speed of light to the many horrible ways you could die while building a periodic table out of all the actual elements.
The book features new and never-before-answered questions, along with the most popular answers from the xkcd website. What If? is an informative feast for xkcd fans and anyone who loves to ponder the hypothetical.

每天上班路上,有一条河堤路，路上只有两条车道双向的。经常有车来来往往，想要超车比较需要技术，一定是对面车道没有车或者车离着比较远的时候，迅速超越前车，加速，油门，转向，加速，加大油门，转向，请为一个开车娴熟的女司机鼓掌，谢谢。 这段路上总会经过一个阶段式的减...
评分主要内容 这本书提出了很多那些古怪又让人忧心的问题，并且做出了一定的回答。因为都是围绕者问题去写，所以每个问题自成体系，很难做出一个提纲挈领的概括或者主题。虽说这些问题有些荒诞，但是能提出这些问题就很棒，拥有无尽的想象。 异想天开 在我小的时候，中央一有一个由...

用户评价
还行吧，作者有点刻意卖弄的感觉
评分5月20日下的单，啃到前天才读完。不是特别吸引人，毕竟是科普没有剧情，但作者已经写得非常有趣，漫画的幽默总是让人会心一笑。英文版看不懂的地方有不少，很多词词典查不到，有些幽默的部分和提到人名地名的部分，由于文化差异很难有共鸣。选择回答的问题可能大多适合美国人脑洞大开的口味，我个人的话看完之后受到震撼留下印象的信息很少。感觉这本书对综合知识和数理基础深厚的或者科学从业者来说会更有启发和趣味。
评分阅读的是Houghton Mifflin Harcourt的kindle版，豆瓣有两个重复条目
