What if? 2

Following on from XKCD, “What if?,” and “How to” comes Randal Munroe’s “What if? 2.” It’s another collection of silly questions with scientific, humorous answers. Examples include “Could you eat a cloud?” and “How far could you see if you had an eye as big as the earth?”

It’s as simple as this: if you liked those books, you’ll like this one.

“Incineration of organic matter within it” is a bad feature for an umbrella.

If I have a criticism, it’s that it feels like it’s playing by numbers at this point. All the same ingredients are there. I did enjoy it — I genuinely laughed out loud at parts of it — but it’s not as fresh and original as, well, the original. Is this the fate of all sequels?

How to

“If you convert [your car] to run on copies of this book instead of gas, it will burn through 30,000 words per minute, several dozen times faster than the word consumption of a typical human.”

If you thought that “How to“, the follow-up to “What if…” would be more practical, then you’d be wrong.

Whether it’s chasing a tornado without getting up from your couch or moving your house with jet engines, Munroe takes another fun, inventive journey through science and maths. While it doesn’t quite hang together as well as “What if,” it still manages to amuse, educate1 and entertain.

There are so many good bits that it’s difficult to mention even a few highlights, but I think possibly my favourite part is where he fails to faze Colonel Chris Hadfield, even when asked how to land a space shuttle that’s attached to the carrier aircraft (response: “Easy peasy”).

If you’re at all interested in science or engineering, you should read this book (if you haven’t already). Just — please — don’t take the advice literally.


  1. I mean, not directly. You’re unlikely to have an exam where you need to know how to build a lava moat. But the thought-process in getting a serious answer to an absurd question absolutely has value. ↩︎

Sex Power Money

This book isn’t what I was expecting. I know Sara Pascoe’s standup and thought this might be some fun, light reading.

To be fair, the writing does have fun bits but the subject matter? Not so much. Relationships, power dynamics, tesosterone, prostitution. Heavy stuff! She’s clearly done reseach and quotes interviews1 she’s conducted. This is no “memoir” as many comedians have done. But nor is it an academic treatise. There are still personal bits, as she discusses the struggles she had grappling with some of the more challenging concepts or how her opinions had changed over time. It’s a refreshing approach as most authors push the solution rather that the journey to it. Sometimes the route is more interesting than the destination.

Overall it’s thought-provoking stuff and worth a read for that reason alone. You may not agree with all of it but you might have the odd snigger reaching that conclusion.

What if…?

“What if…?” is a totally ridiculous idea for a book and pretty much perfect because of it. The concept is asking all kinds of silly questions and seeing where they go. For example, what if a the earth suddenly stopped spinning? (Spoiler alert: it’s not good.)

There’s a beauty to both asking and taking the time to answer “absurd hypothetical questions.” It’s one of those things you’ll either “get” or you’ll think is utterly stupid. (Check out the reviews on Goodreads if you have any doubt.) To be fair, the people in the latter camp are probably not wrong but they’d be missing a lot of fun.

Will you learn anything from this book? A qualified yes. Yes in the sense that you’ll learn the odds of getting full marks on the SATs and the practicality of the human computer in “The Three-Body Problem“. But it’s not a pop-science book in the sense that there’s nothing useful in it.

And, frankly, that’s what I love about it.
