THE SUNDAY TIMES NUMBER ONE BESTSELLER

From the creator of the wildly popular xkcd.com, hilarious and informative answers to important questions you probably never thought to ask.

Millions visit xkcd.com each week to read Randall Munroe's iconic webcomic. Fans ask him a lot of strange questions: How fast can you hit a speed bump, driving, and live? When (if ever) did the sun go down on the British Empire? When will Facebook contain more profiles of dead people than living? How many humans would a T Rex rampaging through New York need to eat a day?

In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations and consults nuclear reactor operators. His responses are masterpieces of clarity and hilarity, complemented by comics. They often predict the complete annihilation of humankind, or at least a really big explosion.

From the Publisher

Product description

Review

With this book and with XKCD, you're a kid with a chemistry set all over again. [Randall Munroe's] enthusiasm for all things scientific is infectious . . . required reading for grown-ups, it's just fun to remember that science is really, really cool (REGISTER)

Smart answers to silly questions: Randall Munroe reveals all (GUARDIAN)

What If? maintains a delightfully free-wheeling tone throughout, especially when complicated calculations lead to whimsical results. Despite all the hard facts and gigantic numbers, it never feels like a textbook-and you don't have to be a rocket scientist to enjoy it (ENTERTAINMENT WEEKLY)

The best bathroom book you'll ever buy...Munroe takes inane, useless and often quite pointless questions asked by real humans (mostly sent to him through his website), and turns them into beautiful expositions on the impossible that illuminate the furthest reaches, almost to the limits, of the modern sciences .The first chapter, "Q. What would happen if the Earth and all terrestrial objects suddenly stopped spinning, but the atmosphere retained its velocity?" ends with the anthropomorphized moon worrying over the state of the Earth, and, with the gravity generated by its own rotation around the Earth, saving our dying planet. The physics are real; so is the emotional content. . . The answers are all illustrated with xkcd's trademark stick figures.. . . . and these are eminently approachable (NEWSWEEK)

Brilliant (ROLLING STONE)

What If? includes old favorites, new inquiries and the mix of expert research and accessible wit that has made Munroe a favorite among both geeks and laymen (TIME)

Munroe's brilliant What-If? column-which features scientifically rigorous, utterly absurd answers to ridiculous hypotheticals-has been on the bestseller lists since it was announced in March. Today, it hits shelves and: It. Is. A. Triumph (BOINGBOING)

[What If?] has solved my annual birthday-present and holiday-gift dilemmas for a large group of people . . . What makes Munroe's work so fantastic is a combination of two elements: his commitment to trying to answer even the weirdest question with solid science, and his undeniable sense of humour. So, here's a "What If?" from me: If everyone on the planet simultaneously bought a copy of this book, stopped what they were doing and read it cover to cover, would modern civilization and our global economy collapse? It's worth trying the experiment. (HUFFINGTON POST)

For the record, I'm loving XKCD's What If -- 'Dear Abby for mad scientists' (NEIL GAIMAN)

Munroe has hit on a wonderful form of science and engineering communication that can do so much-extolling the value of analytical thinking, examining data, and doing back-of-the-envelope calculations-while entertaining readers at the same time . . . an incredibly fun book with quirky, hand-drawn pictures (AMERICAN SCIENTIST)

Thoughtful, scientific, and highly entertaining (PARADE)

If you're the kind of person whose brain whizzes with questions, Munroe's book may calm the noise. He's done all the hard work for you (SHORTLIST)

XKCD is nerd royalty, the alpha dork, there's no geek more widely cited and loved (BEN GOLDACRE, author of BAD SCIENCE)

It's totally brilliant and everyone who matters already knows that! (TIM HARFORD, THE UNDERCOVER ECONOMIST)

Education should aim to teach people to reason confidently about problems that they have never come across before. This book is a great deal of fun, and a masterclass in such reasoning. Like all the best lessons, you only realise you've learnt something once you've finished it (The Economist)

Dangerously absorbing . . . if you have ever been gripped by an insatiable, preposterous intellectual curiosity (regardless of actual scientific knowledge), I could not think of a better book to keep you from doing that essay for an extra hour or two (Varsity)

The reader is left constantly subject to outbursts of laughter, lingering doubts concerning the sanity of the human race, and an ever-growing fascination with the way our world and the universe works . . . Though science geeks will be the first to acknowledge Munroe's greatness, even people suffering from a chronic hatred towards anything concerned with math will find the humour and absurdity of What If? hard to resist (The Student)

Funny and fascinating: brilliant for dinner with mates (Graeme le Saux)

It will satisfy the curious and arouse curiosity in anyone who's not - and it's got great jokes (Irish Times)

An essential holiday companion (Nature)

Book Description

Science's most intriguing questions answered by the web's favourite writer, the genius behind xkcd.com.

Munroe's hilarious and compelling answers explain everything from the odds of meeting your one true soulmate to how many humans a rampaging T-Rex would need to eat a day.

what if......

"What If?" by Randall Munroe is a delightful exploration of the bizarre, absurd, and seemingly impossible questions that have intrigued curious minds for generations. Munroe, a former NASA roboticist and the creator of the webcomic xkcd, takes readers on an intellectual rollercoaster ride through a series of hypothetical scenarios, offering serious scientific answers with a hefty dose of wit and humor. Here's why "What If?" is a must-read for anyone who enjoys pondering the strange and fantastical:

Clever and Engaging: Munroe's writing is clever, engaging, and infused with a unique sense of humor. He takes the most outlandish questions, such as "What would happen if you tried to hit a baseball pitched at 90 percent the speed of light?" and breaks them down into scientifically sound, yet often hilarious, explanations.

Scientific Rigor: Despite the absurdity of the questions, Munroe maintains scientific rigor throughout the book. He diligently researches and consults experts to provide well-informed answers, often delving into physics, chemistry, biology, and mathematics.

Accessible Language: Munroe has a remarkable ability to convey complex scientific concepts in an accessible and understandable manner. Whether you have a background in science or not, you'll find the explanations clear and engaging.

Imaginative Scenarios: The scenarios explored in "What If?" are incredibly imaginative and diverse. From calculating the energy required to stop the Earth's rotation to determining the likelihood of finding a soul mate in a world with only 10,000 people, the book is a treasure trove of thought-provoking inquiries.

Humor and Wit: Munroe's humor adds an extra layer of enjoyment to the book. His witty remarks and clever illustrations complement the scientific content, making each scenario both informative and amusing.

Curiosity-Stoking: "What If?" has a way of sparking curiosity and encouraging readers to think critically about the world around them. It invites you to ponder absurd questions and contemplate the underlying scientific principles.

Broad Appeal: This book has broad appeal. It's suitable for science enthusiasts, casual readers, and anyone who enjoys a good laugh. You don't need to be a scientist to appreciate the humor and intellect within its pages.

Fascinating Real-World Insights: Alongside the fantastical scenarios, Munroe provides insights into real-world phenomena, making readers look at everyday things from a new perspective.

In conclusion, "What If?: Serious Scientific Answers to Absurd Hypothetical Questions" is a delightful and intellectually stimulating journey into the realms of the absurd and the scientific. Randall Munroe's unique blend of humor and scientific expertise makes this book a true gem for curious minds. Whether you read it cover to cover or dip into its pages for a quick chuckle and a dose of knowledge, "What If?" will leave you with a newfound appreciation for the wonders and mysteries of the universe, both real and imagined. It's a testament to the power of curiosity and the joy of exploring the unknown.

Fascinating, Funny, Mind-expanding!
Reviewed in the United Kingdom on 14 January 2020

Subtitled ‘Serious Scientific Answers to Absurd Hypothetical Questions’, this book is as entertaining as it is informative. The author is at pains to inform readers that, although he has a degree in physics, he works as the owner/creator of a webcomic, XKCD, he also warns that he is less interested in health and safety than in exploring how things react when blown up, etc.
I love the way he applies science, with an open mind, to the many questions he’s been asked, some of them so odd they’ll make your hair curl. One or two of the questions posed are commonly asked of scientists, and others, but Randall Munroe puts an intriguing spin on his answers to these.
I’ll list just a small sample of the questions posed: ‘What would happen if the Earth and all terrestrial objects suddenly stopped spinning, but the atmosphere retained its velocity’, ‘What would happen if you made a periodic table out of cube-shaped bricks, where each brick was made of the corresponding element?’, ‘Let’s assume there’s life on the nearest habitable exoplanet and that they have technology comparable to ours. If they looked at our star right now, what would they see?’, and ‘How many unique English tweets are possible? How long would it take for the population of the world to read them out loud?’
Eclectic: possibly the best description of the content. Amusing, well thought out, undoubtedly contentious in certain circles, informative and entertaining. The author raises other questions in answering those he is set by correspondents, considering the issues as if the questions were serious (most of the time; he does add brief sarcastic comments for some of the more peculiar questions, especially those that might lead the reader to suspect some twisted motivation on behalf of the questioner!)
This is one of those delightful books readers can dip into in odd spare moments and glean some fascinating information along with the mind-bending possibilities discussed.
Thoroughly enjoyable, educational and funny.

As a person who loves to dream up of near-impossible scenarios and then attempt to quantify them, this book was perfect for me. Truth be told, I had high hopes for this and it did extremely well to live up to my expectations! I was pleasantly surprised at the relatively simple wording used by Randall Munroe to enable the widest range of audience to read it - trust me, a 12 year old could easily process this just as well as an 80 year old. Whether or not they understand it is a whole different kettle of fish.

The only Cons I can think of that the text itself is not long enough. This book is a brilliant weekend read. I wish it lasted more like a week but I guess I have the Internet and the weird parts of YouTube for that. At least there's the XKCD Comics by the same Author which are simply delightful.

So to conclude, if you're looking for something that stimulates your intellectual curiosity, interest in science and making you chuckle, look no further as this book is just for you. Of course many of the negative reviews say its "dull" and contains "stupid questions", but they are completely missing the point of the book (and may lack a sense of humour, even if that humour is derived purely from pity).

If you're a nerd, buy this text for yourself. If you're a teacher, read this to your class in the vain hopes that a spark of intellectuality is triggered in one of your students, if you're a Aunt or an Uncle, buy this book to answer the questions your 4 year old niece or nephew asks like "Why can't we print our own money" followed by an infinite amount of "why's" and a string innocuous questions and if you're a parent to a moody teenager or 'adult' as we like to be called, buy a copy for yourself and for them as well. It may get them to come out of their room.

Enjoy reading!

El libro es cómico, entretenido e interesante, puesto que explica las preguntas más absurdas que podamos tener, esto con bases científicas y muchas investigación, claro que no pueden faltar las clásicas tiras cómicas para darle ese toque especial.

Esta lectura es una forma diferente de hacer comedia y porque no, también aprender cosas nuevas en el proceso.

“What If?: Serious Scientific Answers to Absurd Hypothetical Questions” von Randall Munroe ist ein unglaublich unterhaltsames und zugleich lehrreiches Buch. Munroe, der Schöpfer von xkcd, gelingt es, scheinbar absurde und oft witzige Fragen mit ernsthafter wissenschaftlicher Akribie zu beantworten. Ob es darum geht, was passieren würde, wenn man einen Baseball mit Lichtgeschwindigkeit wirft oder wie hoch man eine Erdmauer stapeln könnte – seine Antworten sind gleichermaßen verblüffend wie humorvoll.

Besonders gefällt mir, dass das Buch komplexe wissenschaftliche Zusammenhänge auf eine leicht verständliche Weise erklärt, ohne dabei je langweilig zu werden. Die Erklärungen sind voll von witzigen Illustrationen und trockenen Kommentaren, die das Lesen zu einem Vergnügen machen. Gleichzeitig lernt man eine Menge über Physik, Mathematik, Biologie und andere Naturwissenschaften – ganz ohne das Gefühl, dass es sich um ein Lehrbuch handelt.

Munroes einzigartiger Humor und seine Fähigkeit, wissenschaftliche Theorien auf lustige und kreative Weise zu präsentieren, machen dieses Buch zu einer perfekten Mischung aus Unterhaltung und Wissen. Egal, ob man ein Wissenschafts-Fan oder einfach nur neugierig auf skurrile Fragestellungen ist – dieses Buch wird definitiv zum Nachdenken anregen und für viele Lacher sorgen.

Insgesamt ist es ein absolutes Muss für jeden, der Spaß an kuriosen Gedankenspielen und cleveren Erklärungen hat. Sehr zu empfehlen!

This book opens with the best disclaimer I have ever seen:

"Do not try any of this at home. The author of this book is an Internet cartoonist, not a health or safety expert. He likes it when things catch fire or explode, which means he does not have your best interests in mind. The publisher and the author disclaim responsibility for any adverse effects resulting, directly or indirectly, from information contained in this book."

That disclaimer really sets the tone for this fun book about science: Dangerous ideas ahead, folks! Don't get too close -- these things could kill ya!

Randall Munroe used to work at NASA, and now he creates the webcomic XKCD (which sounds less stressful than the NASA gig). On his website, he takes "absurd hypothetical questions" from readers and tries to answer some of them. Here are some of my favorite questions in this book:

What would happen if everyone on Earth stood as close to each other as they could and jumped, everyone landing on the ground at the same instant?

If every human somehow simply disappeared from the face of the Earth, how long would it be before the last artificial light source would go out?

How long could a nuclear submarine last in orbit?

From what height would you need to drop a steak for it to be cooked when it hit the ground?

If everyone on the planet stayed away from each other for a couple of weeks, wouldn't the common cold be wiped out?

Which US state is actually flown over the most?

Is there enough energy to move the entire current human population off-planet?

How high can a human throw something?

How fast can you hit a speed bump while driving and live?

When, if ever, will the bandwidth of the Internet surpass that of FedEx?

How quickly would the oceans drain if a circular portal 10 meters in radius leading into space were created at the bottom of Challenger Deep, the deepest spot in the ocean? How would the Earth change as the water was being drained?

How many Lego bricks would it take to build a bridge capable of carrying traffic from London to New York? Have that many Lego bricks been manufactured?

What would happen to the Earth if the Sun suddenly switched off?

If you are interested to know any of the answers to those questions, this book is for you! What made this so much fun, aside from the ridiculous questions, is Munroe's sense of humor. Several times I laughed out loud at his drawings and his answers, which is not something that usually happens when I'm reading about science. Oh, and be sure to read his footnotes, which have even more jokes.

I think this book would be a great gift for kids who love to ask crazy questions about how the world works. I think I would have loved it when I was 10.
