As a fan of XKCD, I've loved the What If? spinoff series despite how irregularly Randall has updated it. Considering there have only been five new posts in the last five years, and they were all in the months leading up to the release of this book, I needed a good dose of What If? Partly because it had been so long since I had read any What If? posts, all the chapters in this book felt fresh and hilarious. Now that I read through it, I'm sad that I'll have to wait another eight years for a third book in the series.
Randall always has a down-to-earth style of describing incredibly complicated scientific concepts. This means What If? 2 is quite educational once you get past the ridiculous premises that readers have sent in. It's also nice how each chapter is easily readable in a few minutes so that I could just pick it up and get a good laugh before moving on to something else. After all, this book is straight-up funny. This should come as no surprise—again—given the absurd questions readers asked Randall.
It felt like this book had more new content than the previous book in the series. This might not be true, but it felt that way because I hadn't read any of the posts that made it into this book in several years. This was my main qualm with the first book: that it was just a printed-out part of the internet. In this sequel, there weren't just new questions answered but also quick little sections that covered easily answerable questions (as compared to its predecessor's highlights of disturbing questions with no answers). Overall, I found it to be a fun read and I'm counting the days until What If? 3 comes out.
Hilarious and scientifically accurate answers to oddball questions, I give What If? 2 4.5 stars out of 5.
