What If?

2014

In What If?, Randall Munroe takes absurd hypothetical questions and tries to answer them with science. What would happen if you tried to hit a baseball pitched at 90% the speed of light? What if everyone on the planet pointed a laser pointer at the moon simultaneously? Munroe uses his impressive background in physics and computer modeling to take seemingly ridiculous questions and turn them into lessons about the complexities of the universe. With humor woven throughout, What If? is a fun and engaging read for anyone interested in science, technology, and the limits of imagination.
