Why do people laugh? Why can some people roll their tongues, but others can't? How will future astronauts deal with the strains of long trips through space? When you swing a bat at a baseball, why can't you "keep your eye on the ball"? The eleven explorations in this book cover some of the most fascinating questions about our bodies. From baseball to mountain climbing, from jet flights to spaceflight, these questions are the reader's gateway into real science. In his warm, personal style, Jack Myers explains some of the health threats of our time, such as sunburn, smoking, and loud sounds. In many other chapters, he takes on questions of pure curiosity. He shows that science is much more than a collection of facts. It's an adventure of discovery. The reader comes along as scientists learn surprising new things... and as they end up with new and intriguing questions. Many full-color illustrations help draw young scientists into this stimulating read.
