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!
P.S. How will the alt-text and footnotes be handled in the book? Will they simply be actual footnotes at the bottom?

What’s the difference between the UK/Commonwealth edition and the American one? Just spelling localisation or content?
How many questions will there be?
Do we lose out on the alt text altogether or will it go into captions?

This is great news! Congrats, I can’t wait.
I am not privy to any of the details of this deal, but to the questions some other people have asked about different versions of the book, here are some general answers from my experience with Machine of Death:
• US and Canada are served by the same book publishers, although different distributors. So Canadians can expect to get the same book, but it won’t show up on amazon.ca until the Canadian distributor puts it there, which may take longer.
• All book publishers these days publish ebook editions. So rest assured there will be a Kindle edition, and it’ll also be on all the other ebook sites (B&N, Kobo, iBooks, etc). It’s very unlikely there will be a straight ePub available for download outside of an ebook reseller (although Calibre will convert a file downloaded from one of those services). This is no fault of Randy’s, it’s just how books are distributed by the industry.
• UK, Australia, and New Zealand are served by UK publishers. It seems there will be a UK edition, which will probably be identical except potentially with a different cover (about half the time they change the cover to serve a different market). This just means that a UK publisher (possibly a different branch of Houghton, possibly not) got the rights to distribute the book in their market independently of the US publisher.
• In the same way, Australia/NZ are served by different distributors than other territories, so it may take a little time for the book to show up on all the different sites. The book isn’t due out until September so there’s plenty of time for all that to shake out.
Congrats again Randy!

For those of us not in the UK or US and so not served well by either flavor of Amazon – The Book Depository (free shipping worldwide) has it listed (not as aggressively discounted as amazon.com, but cheaper than from the US with shipping at least)

If this week marks the 87th comic, haven’t you only been doing this for 1.67 years, not “For the last couple years”. Maybe I’m missing something. But that’s cool about the book!

If the What If book were carved into the face of the moon, in a font large enough to be read on the current highest resolution orbital lunar surface imagery, how long would it remain legible? How much area would it take up? How much material would be excavated, assuming the carving profile is a neat 45-degree “V” shape?
Honestly, “What If?” is a highlight of my week, something to look forward to about Tuesdays. Excited about the book; will have to remember to keep checking Amazon.ca for the Canadian release.

I like kindle versions, but illustrations usually suck on Kindle, so I’d settle for a dead tree paper.
It would make sense to list it under amazon.ca
