An artillery shell hits the side of a house; its impact breaks through a wall or a window, the subsequent explosion blows out the whole side of the house, or takes the roof off, and the damage is the result of a precise equation depending on the trajectory of the shell, the angle of impact, the yield of the explosion, and the physical properties of the construction elements of the house - the brittleness of bricks and mortar, the elasticity of steel or timber or the density of concrete, the only material to provide any degree of protection.
