Development of the vacuum assisted closure technique. The practice of exposing a wound to sub-atmospheric pressure for an extended period to promote debridement and healing was first described by Fleischmann et al in 1993 [1], following the successful use of this technique in 15 patients with open fractures.

Physics is the study of matter, energy, and their interactions with one another. Physics seeks to study the world around us, the world inside us, and the world beyond us. It is the foundation of all other natural sciences, including chemistry, biology, oceanography, geography, and radiography.
