Blog: Krulwich Wonders
We appreciate double meanings. Robert Krulwich, as NPR's main science blogger, wonders about the wonders of science, and he brings us all along for the ride. Where should people stand in a packed elevator? Where is an ice-loving insect going to go when the world warms up? Which is bigger: The human brain or the universe? Krulwich asks deceivingly simple questions, which -- ironically -- are often the most difficult and amazing to answer.
