In this first-ever popular introduction to maglev-- the use of magnetic forces to overcome gravity and friction--Livingston takes lay readers on a journey of discovery, from maglev nanotechnology to Chinese trains that travel at 250 mph without touching the tracks. He finds magic in fighting friction by fighting gravity.
