About this listen
A special tenth anniversary edition of the million-copy bestseller What If? from the creator of the wildly popular webcomic xkcd—revised and annotated with answers to important questions you never thought to ask.
Fans of xkcd ask Munroe a lot of strange questions: What if you tried to hit a baseball pitched at ninety percent the speed of light? How fast can you hit a speed bump while driving and live? If there was a robot apocalypse, how long would humanity last? What if everyone only had one soulmate? What would happen if the moon went away?
In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators. His responses are masterpieces of clarity and hilarity, complemented by his signature xkcd comics. (They often predict the complete annihilation of humankind, or at least a really big explosion.)
In celebration of ten years of unusual insight, Randall Munroe has revised his classic blockbuster to ask what if? times ten. The result is ten times the adventure of scientific inquiry. This special anniversary edition is far more than a book for geeks, What If? explains the laws of science in operation in a way that every intelligent listener will enjoy and feel much smarter for having listened to.
PLEASE NOTE: When you purchase this title, the accompanying PDF will be available in your Audible Library along with the audio.

Story
From the masters of storytelling-meets-science, Patient Zero tells the long and fascinating history of disease outbreaks—how they start, how they spread, the science that lets us understand them, and how we race to destroy them before they destroy us. Written in the authors’ lively style, chapters include gripping medical stories about a particular disease or virus—smallpox, Bubonic plague, polio, HIV—that combine “Patient Zero” narratives, or the human stories behind outbreaks, with historical examinations of missteps, milestones, scientific theories, and more.

They say you can't teach an old dog new tricks. But what about relativity? Physics professor Chad Orzel and his inquisitive canine companion, Emmy, tackle the concepts of general relativity in this irresistible introduction to Einstein's physics. Through armchair- and sometimes passenger-seat-conversations with Emmy about the relative speeds of dog and cat motion or the logistics of squirrel-chasing, Orzel translates complex Einsteinian ideas into examples simple enough for a dog to understand.

History is the most dangerous place on earth. From dinosaurs the size of locomotives to meteors big enough to sterilize the planet, from famines to pandemics, from tornadoes to the Chicxulub asteroid, the odds of human survival are slim but not zero—at least, not if you know where to go and what to do. In each chapter of How to Survive History, Cody Cassidy explores how to survive one of history’s greatest threats: getting eaten by dinosaurs, being destroyed by the asteroid that wiped out the dinosaurs, succumbing to the lava flows of Pompeii, being devoured by the Donner Party, and more.

From blurry vision to crooked teeth, ACLs that tear at alarming rates and spines that seem to spend a lifetime falling apart, it's a curious thing that human beings have beaten the odds as a species. After all, we're the only survivors on our branch of the tree of life. Why is it that human mothers have such a life-endangering experience giving birth? And why are there entire medical specialties for teeth and feet? In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells us just where we inherited our achy, brilliant bodies in the process of evolution.

Just over 125,000 years ago, humanity was going extinct until a dramatic shift occurred—Homo sapiens started tracking the tides in order to eat the nearby oysters. Before long, they’d pulled themselves back from the brink of extinction. The human brain, and its evolutionary journey, is unlike anything else in history. In A History of the Human Brain, Bret Stetka takes listeners through that far-reaching journey. He also tackles the question of where the brain will take us next, exploring the burgeoning concepts of epigenetics and new technologies like CRISPR.

On June 4, 1944, the course of World War II was forever changed. That day, a US Navy task force achieved the impossible—capturing a German U-Boat. Called Operation Nemo, it was the first seizure of an enemy ship in battle since the War of 1812, one of the greatest achievements of the US Navy and a victory that shortened the duration of the war. A deeply researched, fast-paced World War II narrative for the ages, Charles Lachman’s white-knuckled war saga and thrilling cat-and-mouse game is told through the eyes of the men on both sides of Operation Nemo.

Story
History is the most dangerous place on earth. From dinosaurs the size of locomotives to meteors big enough to sterilize the planet, from famines to pandemics, from tornadoes to the Chicxulub asteroid, the odds of human survival are slim but not zero—at least, not if you know where to go and what to do. In each chapter of How to Survive History, Cody Cassidy explores how to survive one of history’s greatest threats: getting eaten by dinosaurs, being destroyed by the asteroid that wiped out the dinosaurs, succumbing to the lava flows of Pompeii, being devoured by the Donner Party, and more.

Story
The American Civil War stands at the center of the story, its military history and the drama of emancipation the highlights. Taylor relies on vivid characters to carry the story, from Joseph Hooker, whose timidity in crisis was exploited by Robert E. Lee and Stonewall Jackson in the Union defeat at Chancellorsville, to Martin Delany and Mary Ann Shadd Cary, Black abolitionists whose critical work in Canada and the United States advanced emancipation and the enrollment of Black soldiers in Union armies.

Story
On June 4, 1944, the course of World War II was forever changed. That day, a US Navy task force achieved the impossible—capturing a German U-Boat. Called Operation Nemo, it was the first seizure of an enemy ship in battle since the War of 1812, one of the greatest achievements of the US Navy and a victory that shortened the duration of the war. A deeply researched, fast-paced World War II narrative for the ages, Charles Lachman’s white-knuckled war saga and thrilling cat-and-mouse game is told through the eyes of the men on both sides of Operation Nemo.

From blurry vision to crooked teeth, ACLs that tear at alarming rates and spines that seem to spend a lifetime falling apart, it's a curious thing that human beings have beaten the odds as a species. After all, we're the only survivors on our branch of the tree of life. Why is it that human mothers have such a life-endangering experience giving birth? And why are there entire medical specialties for teeth and feet? In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells us just where we inherited our achy, brilliant bodies in the process of evolution.

This kaleidoscopic book covers almost 3,000 years of Arab history and shines a light on the footloose Arab peoples and tribes who conquered lands and disseminated their language and culture over vast distances. Tracing this process to the origins of the Arabic language, rather than the advent of Islam, Tim Mackintosh-Smith begins his narrative more than a thousand years before Muhammad and focuses on how Arabic, both spoken and written, has functioned as a vital source of shared cultural identity over the millennia.

A talented and intelligent author, artist, mathlete (want sum?)
Considering I read this for the first time in 2025 (I really need to read original release dates), I found the updates to be some of my favorite parts. WW does a great job as well, I’d say one of his best. I hope future is comes and saves us soon. Oh, and I hope frozen teeth lady got arrested. 😅

Best of...the title should have been
Read some reviews and disagreed. The 10th Anniversary is (while a repeat of some from the last 2 x books) is really a "best of"...
So read all of the previous versions, or just read this one. Regardless you will be smarter and have a load of info for your next TGIF event.
Thank you, is all I have to say...thank you!!
