Book excerpt: From world-renowned autism spokesperson, scientist, and inventor Temple Grandin -- a book of personal stories, inventions, and facts that will blow young inventors' minds and make them soar. Have you ever wondered what makes a kite fly or a boat float? Have you ever thought about why snowflakes are symmetrical, or why golf balls have dimples? Have you ever tried to make a kaleidoscope or build a pair of stilts? In Calling All Minds, Temple Grandin explores the ideas behind all of those questions and more. She delves into the science behind inventions, the steps various people took to create and improve upon ideas as they evolved, and the ways in which young inventors can continue to think about and understand what it means to tinker, to fiddle, and to innovate. And laced throughout it all, Temple gives us glimpses into her own childhood tinkering, building, and inventing. More than a blueprint for how to build things, in Calling All Minds Temple Grandin creates a blueprint for different ways to look at the world. And more than a call to action, she gives a call to imagination, and shows readers that there is truly no single way to approach any given problem--but that an open and inquisitive mind is always key. Praise for Calling All Minds: "An impassioned call to look at the world in unique ways with plenty of practical advice on how to cultivate a curious, inquiring, imaginative mind." —Kirkus Reviews "Both practical and inspirational, this useful book describes an overall approach to viewing the world creatively, as exemplified by the numerous projects and supporting material provided here." —VOYA "Grandin offers a nuanced perspective on the qualities of a successful inventor—notably, a sense of wonder and curiosity, careful observation, and the willingness to learn from mistakes." —Publishers Weekly
