CRUISERS! This week we are headed back to Caltech, for a delve in the realm of structural engineering. Since 1881, research into granular materials has looked at low impact absorption. However, thanks to Dr. Hayden Burgoyne, we now understand how to use these materials to protect against high velocity high force impacts. We also have an interesting analog to optics to help us design 'lenses' to redirect the wave energy away from critical areas. Enjoy!!
