What if I wrote a book?

For the last couple years, I’ve been answering your science questions on What If.

Today, I’m excited to announce that the What If? book is coming!

What If?: Serious Scientific Answers to Absurd Hypothetical Questions will be published September 2nd by Houghton Mifflin Harcourt. Starting today you can pre-order it from your favorite bookseller (Barnes & NobleAmazonIndie Bound).  There are also foreign editions, including a UK and Commonwealth edition and a German edition.

As I’ve sifted through the letters submitted to What If every week, I’ve occasionally set aside particularly neat questions that I wanted to spend a little more time on. This book features my answers to those questions, along with revised and updated versions of some of my favorite articles from the site. (I’m also including my personal list of the weirdest questions people have submitted.)

Preorder today to get a copy as soon as it comes out!

  1. Why is the UK version about twice as expensive as the US one? Are the 16 extra pages it contains printed on gold leaf?

  2. Preordered from Spain through Amazon.es 🙂 A little rough $->€ conversion, though.

  3. I’m in India. I’d buy an eBook version directly if it were:
    1. DRM free
    2. Available for a price lower than the physical book (that should be obvious, no?)
    3. In ePub format (although PDF is also ok)

    A printed book from the U.S. is a pain to deal with in more ways than one.

  4. I’m just going to comment here that both the US and UK editions are available on The Book Depository, an online book retailer that ships free to more than 100 countries. Their prices are usually fairly competitive and the two books I’ve preordered from them actually arrived a couple days before their release dates.

    I don’t have any affiliation with the site and I don’t do all of my book shopping with them but they can be amazing if the book you want is being released in the US or UK but not where you are.

  5. When you say “nonfatal” manner, you mean non fatal for the book or the delivery man/woman? Both?

  15. I’ve read many of your What-if articles and haven’t understood a single one of them. Almost all involve such large numbers that I run right out of fingers. And toes! I’m fine with single digit sums, but come on, is long division really necessary?

    It would be a refreshing change if you could answer a question using less mathematics and more poetic imagery. Replace galloping exponentials with a gentle linguistic cantor. Let rhythmic prose replace rampant zeros. Let soft words wrap the harsh edges of physical reality. Please.

    What If … I were smarter than my smart phone?

  16. when you say non fatal, just exactly how non fatal are you talking about? Could you classify non fatalism using a scale of 1-5, with 1 being moderately non fatal and 5 being extremely non fatal?

  17. I am intrigued that “UK and Commonwealth” is a “foreign” edition – how does it differ from the US edition? It intriguingly has 16 extra pages. They have to be good to justify the 67% higher price! 😉

  19. I know it’s been said, but if there was any way to get an autographed copy that would make a world of difference for me.

    I’m hesitant to pre-order the book now for fear that an autographed edition will suddenly be a thing, and I’ll be stuck with my silly non-autographed copy.

  20. @clifford: [I am intrigued that “UK and Commonwealth” is a “foreign” edition – how does it differ from the US edition? It intriguingly has 16 extra pages.]

    I think the extra pages are the result of having to spell colour and rigour and similar words with the extra “u.” One can see how small differences can yield enormous effects.

    The higher price would be partial reparations for what it cost us to wrest the colonies from the grasp of your ancestors. It’s only fair. 😉

  22. OK, you finally got me to pre-order the book, after looking at your post for a month now. I was looking forward to it being delivered by a Velociraptor, however I understand current Velociraptor cloning may not be complete by September. Anything you could do to help expedite that process in time for delivery would be much appreciated.

  26. I support the use of a non fatalism scale so that we can predict more accurately how the book will arrive. On a non fatalism scale of 1-5, 1 could be just barely non fatal, such as the recipient being completely paralyzed except that you can still move your eyes to read the book. This might be the result of the lava surfing velociraptor method. 5 would be extremely non fatal, like the headache my wife gets when I want to have sex. That would be a good time to read your book.

  30. Why does the preorder price on Amazon keep creeping up? When I first looked, it was $14.99. Then a few days later, it was $15.14. Then a few more days later it was $15.44. Will the preorder price just keep creeping up until it reaches the full retail or something the closer it gets to release?
