At times this book was a bit over my head, but it kept my interest. The author was very funny which helped!

Good idea overall, but it didn't work for me.

The book excels at taking the absurd seriously, with hefty doses of humor and nerdery.

This was such a fun book to read and yet surprisingly informative. I now know which states have the fewest fly overs, what would happen if everyone on earth jumped at once, what would happen if the sun died, what would happen if everyone on earth pointed lasers at the moon, and so on. I unfortunately didn't get to finish it before it was due back at the library, but it's the kind of book one can pick up and read in spurts.

A hugely entertaining read -- I laughed out loud many times -- and also, I learned stuff. What more could you ask for?

It's an awesome book but one I now just like to pick up and flip through or read small bits here and there.

Piacevole, ma un po' troppo "leggero". Ho preferito l'italianissimo "Se tutte le stelle venissero giù".
