The Sonic RAREFACTION WAVE GUN (RAVEN) is a Projectile Launch Method that achieves: – Unprecedented Reductions in Recoil Impulse. It can shoot faster, cooler and can be lighter than a current gun ...

The compressible Navier-Stokes equations form the cornerstone of fluid dynamics, describing the motion of viscous compressible fluids under conservation of mass, momentum and energy. By incorporating ...

Rarefaction has long represented a powerful tool for detecting species richness and its variation across spatial scales. Some authors recently reintroduced the mathematical expression for calculating ...

Inspired by the paper folding art of origami, a University of Washington team created a paper model of a metamaterial that uses 'folding creases' to soften impact forces for potential applications in ...

Introduction You may have heard that light consists of particles called photons. How could something as simple as light be made of particles? Physicists describe light as both a particle and a wave.
