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 & Noble, Amazon, Indie 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!
I’m Canadian and I’d consider ordering this book off of amazon.ca!

You may want to consider whether it’s best for you to encourage pre-orders from online resellers, since they tend to reduce sales figures when the book comes out, and those figures can help make a book more visible on those resellers’ websites.

Wow, I actually had no idea you even did a what-if feature until you announced the book! Now I’m 5 entries in and loving it, so I kind of want to buy the book for my son…who is 17 months old…he probably won’t understand much yet…but oh, when he does!

Yeah, Place 1 on in English Books and place 1331 in all books on amazon.de.
I ordered both, just in case the translation doesn’t get the scientific humor.
Two thumbs up!

As a long time fan of xkcd (and having gained the honor of being able to say that I’ve looked at literally every.single.comic during a particularly slow summer as a concierge), I am so thrilled to hear about this book. I was just sharing your What If column with my boyfriend the other day, and I was reminded again of how much I enjoy just about everything you manage to produce. Best of luck with book sales!

What’s up with the Amazon UK prices?
Amazon offer a “Price Guarantee” on this book – that means “if the Amazon.co.uk price decreases between the time you place your order and the release date, you’ll be charged the lowest price”. Seems simple enough.
I ordered the book when the price was £14.79. It’s now £11.40. So I should get the cheaper price, right? Apparently not!
The edition I ordered has since gone up to £14.99 and been renamed to “Hardcover, 4 Sep 2014”. Then there’s a *separate* edition called just “Hardcover”, which is £11.40. So that leaves me paying £14.79 when new purchasers can pay £11.40.
What’s up with that?
Is someone (Amazon or publisher) trying to game their way out of the Price Guarantee? Randall, please can you investigate this?

To Jon Spell, about your bobcat concern, the probability of you NOT receiving a bobcat, statistically speaking is not 0%. Just be alert. To paraphrase Ygritte, “You know nothing Jon Spell.” 😉
