What would you do if a time machine hurled you thousands of years into the past...and then broke? How would you survive? With this book as your guide, you'll survive - and thrive - in any period in Earth's history. Best-selling author and time-travel enthusiast Ryan North tells you how to invent all the modern conveniences we take for granted - from first principles.

The millions of people around the world who loved What If? still have questions, and those questions are getting stranger. Thank goodness xkcd creator Randall Munroe is here to help. Planning to ride a fire pole from the Moon back to Earth? The hardest part is sticking the landing. Hoping to cool the atmosphere by opening everyone’s freezer door at the same time? Maybe it’s time for a brief introduction to thermodynamics. Want to know what would happen if you rode a helicopter blade, made a lava lamp out of lava, or jumped on an erupting geyser? Okay, if you insist.

For any task you might want to do, there's a right way, a wrong way, and a way so monumentally complex, excessive, and inadvisable that no one would ever try it. How To is a guide to the third kind of approach. It's full of highly impractical advice for everything from landing a plane to digging a hole.

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.

Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world. Getting it wrong has never been more fun.

We live in a “post-truth” world, we’re told. But was there ever really a golden age of truth-telling? Or have people been lying, fibbing, and just plain bullsh*tting since the beginning of time? Tom Phillips, editor of a leading independent fact-checking organization, deals with this question every day. In Truth, he tells the story of how we humans have spent history lying to each other - and ourselves - about everything from business to politics to plain old geography.

From the Silicon Valley tech billionaires currently trying to work out whether or not the universe is one giant video game simulation to the self-proclaimed community of Italian time-travelers who are trying to save the world from destruction; The Theory of Everything Else will act as a handbook for those who want to think differently.

From the duo behind the massively successful and award-winning podcast Stuff You Should Know comes an unexpected look at things you thought you knew. Josh Clark and Chuck Bryant started the podcast Stuff You Should Know back in 2008 because they were curious - curious about the world around them, curious about what they might have missed in their formal educations, and curious to dig deeper on stuff they thought they understood.

A gleefully gruesome look at the actual science behind the most outlandish, cartoonish, and impossible deaths you can imagine. What would happen if you took a swim outside a deep-sea submarine wearing only a swimsuit? How long could you last if you stood on the surface of the sun? How far could you actually get in digging a hole to China? Paul Doherty, senior staff scientist at San Francisco's famed Exploratorium Museum, and writer Cody Cassidy explore the real science behind these and other fantastical scenarios.
