Not many books leave you feeling both smarter and wildly entertained. And if a book makes you smarter, then you by definition become a better person for having read it, right?

This was a nice breather after a few of my other recent books. A lot of hypothetical science questions with great explanations. The humor throughout was well placed and not over the top. I also adore Wil Wheaton reading anything science related (don't tell Sheldon). And it was interesting to hear about all these hypotheticals that would/could never happen.

There are a couple times the author answers the question simply and then goes off on a tangent about something totally different, so I skipped the boring ones. But most of this book was fascinating and entertaining. The weird and worrying questions sections had me laughing out loud.

4.5 stars. One of the most fascinating books I've read (listened to) in years. If you know my husband Dustin well, it is sort of like listening to him talk about science -- where serious meets ridiculous.

Loved it. Highly recommended.

This is a fun silly book for those math and physics nerds out there.
