The team will continue their tests using an artificial human arm to model the physical effects of far more severe collisions. (newscientist.com)
By extending the range between the camera and the subject (likely yourself) further than a natural human arm span, it allows the frame of the photo to be expanded. (ordinarytraveler.com)
I was involved in a project that investigated the modulation of human arm stiffness with the presence of external perturbations. (sciencemag.org)
