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!
Preordered on Kindle.
Can you sign my Kindle?

Oooooooooh Sweeeet! X-mas present! What if you told us what the difference between the American and the UK and Commonwealth edition is, so we Other (also non-German) foreigners know which one to pick. 🙂 American $16.52 / September 2 / 320 pages, £14.99 / September 4 / 336 pages. Hm. 16 pages of wonderful stuff that the American censorship could not stomach, but UK/Etc will just use European non-uptight, non-creationist, un-American relaxedness and common sense to handle?

What ?! 15 euros for a non paper version, when the paper version is 16 euros ?!
None of this prices are reasonable to me (for a book), mostly when they are sentences you found on the web.

I’d prefer to preorder it rather than pre-order it, but then I’d worry about whether it had to be a symmetric preorder.

@Lucas, it has nothing to do with US censorship, it has all to do with german language. Germans like to use way longer words and do things difficould and are master in inventing paperwork eventhough the digitalworld exists for over a few decades. You can’t fart here unless you send a minimum of 2 kilos of paper documents to the Steuerambt, with a triple copy to your registered grandma (for security reasons) AND notify g.e.m.a. (for in case you want to whistle a song that might be copywrighted) during said fart.
For easy read just order an english version.

I posted the following comment here before:
“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.”
I would really like to see this so that I can support Randall without hassles. I have supported indie content like those from Humble Bundle mainly because of the DRM free nature and reduced prices (bought xkcd volume from there even though I’ve read all the strips online). I also buy DRM free books from other publishers.
Someone mentioned buying the Kindle edition and stripping DRM from it. I’m not in favor of supporting any DRM format even if it’s a simple process to defeat it. And really, ordering a print book from the U.S. is quite expensive and unreliable.
Thanks for reading this, and hope this need from people who took the time to express their desire in the form of comments helps strengthen the value proposition for the buyers and for Randall.

So… what’s the chance of a fair ebook version that’s not Amazon-locked? I realize it’s convenient to use the Kindle store but it also is incompatible with everything else. Could you ask the Humble guy for help? Given that they released the xkcd book.

@Keyman – Nooks can handle epub, yes. But “normal” epub readers (like my Sony) cannot handle Nook epub. There a second DRM layer on them, as far as I’m informed.
Oh, and this is what B&N thinks about me pre-ordering: “We’re sorry, but this product is only available within the U.S.”

Hi,
On here https://what-if.xkcd.com/18/, you’ve stated that a Genesis Series 1 locomotive weighs 12 tons. They actually weigh about 120 tons.. I believe this may affect your theory slighty…

Very late to this party, but I just noticed the comment about e-books and not wanting to support DRM. Kindle books, currently, are not necessarily DRM. You don’t have to necessarily strip anything. I’ve published via kindle, and there’s a button you press as to whether you want DRM on the book you are publishing or not. Pretty sure that Mr. Munro, like us, would click No. So a kindle version is not automatically supporting DRM. The price issue and what’s available in what countries, I certainly can’t address.

@Jacob (from almost 11 days ago exactly)
My initial reaction to your content question:
I would be surprised if there was any language or adult content unsuitable for a 13 year old, judging from Mr. Munroe’s website. (especially when you consider he did a ‘what if’ post for a 4 year old: http://what-if.xkcd.com/94/ )
But, after thinking about it for a while, I came up with one piece evidence against my claim:
The alt text from http://what-if.xkcd.com/86/
“And more people have had sex in Plymouth Voyagers than Voyager spacecraft, unless NASA JPL is a wilder place than I thought” Although that is taken out of context and, unless I pay less attention than I realize, things like this are rare.
Guess that’s why they have ratings for these sort of things.
