The #1 New York Times bestselling author of What If? and How To answers more of the weirdest questions you never thought to ask

The millions of people around the world who read and 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, built a billion-story building, made a lava lamp out of lava, or jumped on a geyser as it erupted? Okay, if you insist.

Before you go on a cosmic road trip, feed the residents of New York City to a T. rex, or fill every church with bananas, be sure to consult this practical guide for impractical ideas. Unfazed by absurdity, Munroe consults the latest research on everything from swing-set physics to airliner catapult design to answer his readers questions, clearly and concisely, with illuminating and occasionally terrifying illustrations. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances.

Rezension:

Praise for What If? 2

Delightful. . . Randall Munroe has made a career out of sharing his joy in science and engineering. . . . This book and its predecessor inspire us to believe that, even in a vast and mysterious universe, there s a lot we can figure out with nothing but a sharp pencil, come basic scientific knowledge and a vivid imagination. The Wall Street Journal

"The questions throughout What If? 2 are equal parts brilliant, gross, and wonderfully absurd and the answers are thorough, deeply researched, and great fun. . . . Science isn t easy, but in Munroe s capable hands, it surely can be fun." TIME

"Picking this book up now and then enlivens life by letting you briefly consider the effects of, say, putting an indestructible 20-meter-wide glass tube all the way down to the deepest part of the ocean. Plus, Munroe s illustrations turn stick figures and flowcharts into the stuff of existential hilarity." NPR

"Entertaining. . . . combines Munr oe s true research and truly funny prose with his signature stick-figure illustrations." The Washington Post

"Perfect if you enjoy it when stuffy figures of authority crack a smile. Or if you like it when black holes form. That happens a lot." Newsweek

"One of my favorite books of the year." Tim Harford, Financial Times

"It's an absolute delight! It's the coolest way to learn how the world actually works." Hank Green (on the Dear Hank & John podcast)

A delight for science geeks with a penchant for oddball thought experiments. Kirkus

Praise for Randall Munroe and What If?

Randall Munroe is a national treasure. Phil Plait

Extreme astrophysics and indecipherable chemistry have rarely been this clearly explained or this consistently hilarious. Entertainment Weekly 10 Best Nonfiction Books of the Year

Consistently fascinating and entertaining...Munroe leavens the hard science with whimsical touches... An illum inating handbook of methods of reasoning. Wall Street Journal

It s fun to watch as Munroe tackles each question and examines every possible complication with nerdy and methodical aplomb.... The delightfully demented What If? is the most fun you can have with math and science, short of becoming your own evil genius. Boston Globe
