Draining the Oceans and Dreaming Ahead: Randall Munroe’s “What If?”
One of the most interesting things about knowledge and learning is how they allow us to form conjectures, imagine possibilities, engage with the hypothetical; in other words, what we know allows us to imagine what we don’t yet know for certain. The more fanciful and strong imaginations can combine with knowledge to ponder especially perplexing matters. For example, once we’ve learned enough about science, we could look at the earth and ask, “What if it stopped spinning? What would happen?” That question happens to be the first of many discussed in What If?: Serious Scientific Answers to Absurd Hypothetical Questions by Randall Munroe.
