Review of “We Have No Idea”

Posted 18 Aug 17 by arbelos

I loved PhD Comics as a grad student. Frankly, I still find them quite relatable as an Assistant Professor (and in a few years, I can let you know if they’re relatable from a tenured professor’s standpoint!). So I was really intrigued when I heard that the author of PhD Comics, Jorge Cham, co-wrote a book (with Daniel Whiteson) called “We Have No Idea”. It’s not about being a grad student (though the title could probably be reused for a book about that as well); it’s “A Guide to the Unknown Universe”. As the title suggests, it’s about some of the current limits of our knowledge.

If you like popular science books, physics, and astronomy, I definitely recommend this book. Most popular science books talk about what we know, and if you end up with a nagging “but” or a question, it’s hard to tell whether it’s because details were left out, because you misunderstood the explanation, or because you stumbled on an question scientists haven’t figured out yet. This book is different because it explicitly discusses big-picture stuff science hasn’t figured out yet (and suggests some possibilities for what the answers could be). It’s written in the easy-to-read and humorous style of Jorge Cham but co-written with an experimental high-energy physicist, so you can be pretty sure the book is both entertaining and correct.

The book covers dark matter, dark energy, elementary particles, and time, among other things. Even if you’ve read books on these subjects before, reading a book that synthesizes our lack of knowledge in these areas is both enlightening and exciting.
