In Floating, inhabitants of Mammoth Island attempt to rescue an islander and his mammoths from the middle of a lake. They are stranded on a small island after a wooden bridge collapses. Olive, a bright young islander, notices that the wood from the broken bridge is floating on the surface of the lake. With the help of a visiting inventor, she discovers the principle of buoyancy. Every object exerts a downward force on the water, and the water pushes back with an upward force on the object. When the buoyant force is greater than an object’s weight, the object floats!
In Belts & Gears, inhabitants of Mammoth Island are getting ready for their annual fair and are determined to make this year's event better than ever. Olive, a young islander, enlists the help of a visiting inventor to design exciting new rides, and together they decide that using belts and gears will help make the fair a success. While belts and gears don't increase the amount of force applied, they can transfer the force to change direction or speed.

This book details the immense impact that Jorge Luis Borges has had on the thinking and writing of the twentieth century and how many have misunderstood that impact. It highlights how his symbols, techniques, parody, irony, and artful ambiguity in his fiction, essays, and poems force us to question what we can know with certainty, what is real and what is dream, and who we are, and thus define what has become the core of the postmodern vision.
