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!
Happen to arrive at this website from a tech blog… well…don’t remember all the spiders that helped to land here… :p
Just loving the comics’ and have saved the page under Favorites…
Glad to know about the book.. Keep up the writing ..

Instead of book, package contained velociraptor. 😦 Cannot buy again, no arms.

1. What if I ordered the ebook version and it needed to be signed? Would it arrive translated into ASL, or would it arrive via raptor as both a negative and a positive version?
2. What if it was signed by the bobcat AND the raptor, but the Canadian version did not translate its lynx into English?

Have you considered using some of your comics as illustrations too? will there be an eBook version? (Leading a nomadic lifestyle I can’t carry around hardcovers.) Pre-orders (for those who read this and wondered:) are there to let the publisher guess at the initial number of issues to print (otherwise in this day and age pre-ordering would make not that much sense given today’s technology of printing). So for those who contemplate ordering anyway, you’ll make the logistics guys’ job far easier if you ‘fess up now 🙂

I did preorder it!
If it sucks, Randall at least gets some € from me for the many xkcd comics I enjoyed! (and ordering shirts and the like to europe sucks because of the shipping 😦 ) Also it might be good to bring old monitors into a more ergonomical height or make a fire!
But on the other hand, I am pretty sure it won’t suck!

Also, will there be an iTunes edition? If there is I’d totally buy it.

קוראי xkcd מדהימים לואיס Hulbert וירדן ג’ו שמו לב שאיגוד האסטרונומיה הבינלאומי, הארגון אחראי על הצעות למתן שם להיה אסטרונומיים לוקח רשמיות על מה ששם אובייקטי מערכת שמש קטנים. הם הגישו את השם שלי לאסטרואיד (4942) 1987 DU6, ובעקבות זאת הייתה שם 4942 מונרו.
אני באמת נגעתי. ביליתי את כל סוף השבוע לספר לכל מי שרצה לשמוע (וכנראה כמה שלא) על האסטרואיד. درب اتوماتیک کرکره ای
הדבר הראשון שעשיתי היה לנסות להבין אם 4942 מונרו היה גדול מספיק כדי להוות איום ני היה נרגש לשמוע ש, המבוסס על האלבדו שלו (בהירות), זה כנראה כ 6-10 קילומטרים בקוטר. זה דומה בגודלו לזה שהרג את הדינוזאורים, בהחלט גדול מספיק כדי לגרום להכחדה המונית!

I think all 5 of my Norwegian grandkids would like this (they are proficient in English). I also have the urge to donate a copy or two to local schools and libraries, to encourage STEM interest. Maybe one to file under “Humor” (for the unsuspecting, bwa-ha-ha!), and one under science.

This will improve customer satisfaction and also save you money

For that reason, people will not feel put off about it.
Remember, as with any marketing activities, you’re likely to get out of building a social media network exactly what you put into your
participation. Mistake #4: Company Secrets Sometimes, employees will
innocuously announce something on their social
media profile that the company is not ready to
announce publically as of yet. Our other articles discuss specific fundraising ways and fundraising campaigns
for nonprofits, including how to take benefits of online fundraising.
Success depends on the creative skill and the time spent rather than financial depth.
Recently I was doing my whole deal, spinning someone on their head for a seriously flawed perspective of the
world, and the person freaked out and started accusing me of all manner of
things which were either 1. Ultimately, business to business marketers are using social media marketing
methods as well as SEO more effectively to meet
their marketing goals, which is beginning to include improved searches.
It still puzzles me to find businesses that don’t use social media and more importantly, don’t think that it is necessary.
So many business owners make the essential mistake of writing their own social media marketing
blogs.
