What If?

I had never heard of XKCD, but I will start looking at his webcomic soon after this book. The idea of SERIOUS scientific answers to unrealistic-yet-hypothetical-and-funny questions evokes the nostalgic feeling about good old days when I was still innocent & curious (enough) to ask about never-gonna-happen scenarios.

Just a warning that answers illustrated in the books are fairly scientific; meaning that you might wish you would have been able to recall all those physics, chemistry, and maths things you learned in high school. Otherwise, you might have a hard time understanding his explanations.

Or maybe that is just me who forgot everything. Already!
