Randall Munroe, the creator of the web comic xkcd recently published What If? Serious Scientific Answers to Absurd Hypothetical Questions. I found that his curiosity and insistence on asking questions so captivating that I spent more time wrestling with the science than I would have ever guessed that I would.
I think I am very curious, but I really do not care how high a steak would have to be before dropping it would result in its having been cooked by the time it reached my plate. Similarly, I do not lie in bed at night wondering whether there are more soft or hard things in the world.
But reading along as someone applies a wide range of math and science skills to these questions made me wish my curiosity had fewer boundaries.
