Author Don Nardo examines the many aspects of science underlying the popular sport of surfing. This book discusses the physics of waves, the science behind board shape and how riders stay on the board, covering the principles of gravity, buoyancy, and water surface tension. It also covers the scientific principles behind movements such as popping-up on the board; catching a wave; riding a wave; turning; the "hang-ten"; the "duck dive"; the "turtle roll"; and others. Other connections to science are made through discussion of wiping out, rip currents, collisions and typical injuries, hypothermia, and shark attacks. This volume discusses psychological aspects, especially anxiety.
