I had a lot of fun reading this book. Learned some stuff, too. For example: "Can you use a magnifying glass and the moonlight to light a fire?"

Well, maybe a real big magnifying glass, right?

As it turns out… no, no spoilers. Read the darn book.

Long ago, I was a physics major. And Munroe's explanation of the answer is one of those symphonies of elegance that made me love physics. And also had me kicking myself for not getting that answer right away.

The book is full of humor and cartooning in the xkcd style. (Yes, this is the second book I've read this month from a web cartoonist.)
