ackthpt writes "A team of engineers claims to have created the world's lightest material. Made from a lattice of hollow metallic tubes, the material is less dense than aerogels and metallic foams, yet retains strength due to the small size of the lattice structure (abstract). The material's density is 0.9 milligrams per cubic centimeter. Among other things, it's potentially useful for insulation, battery electrodes, and sound dampening."
A method of solution is perfect if we can forsee from the start,
and even prove, that following that method we shall attain our aim.
