And yet, there is no more fundamental human invention than the wheel a rotational mechanism that accomplishes what our physical form cannot. Throughout history, humans have developed technologies powered by human strength, complementing the physical abilities we have while overcoming our weaknesses. Providing a unique history of the wheel and other rotational devices, like cranks, cranes, carts, and capstans, Why the Wheel Is Round examines the contraptions and tricks we have devised in order to more efficiently move and move through the physical world. Steven Vogel combines his engineering expertise with his remarkable curiosity about how things work to explore how wheels and other mechanisms were, until very recently, powered by the push and pull of the muscles and skeletal systems of humans and other animals. Why the Wheel Is Round explores all mann
