I just finished reading What If?: Serious Scientific Answers to Absurd Hypothetical Questions
It’s not just walls of text though, the simple cartoons that first made Randall well known are in the book as well. They often illustrate the absurdity ideas in the answers to completely ridiculous questions.
The bite size format of the book made it perfect for commuting and travel. I was never more than a few moments away from finishing a chapter. Each chapter provided a natural break point, though I always wanted to read just one more.
