A computer-implemented method teaches a user to evaluate a gemstone, such as a cut diamond. The method includes providing a computer system connected to an apparatus capable of capturing an image of a gemstone. The computer system is arranged to process a received image of a gemstone to determine one or more optical properties of the gemstone. In one aspect, the method presents on a display of the computer system a series of pre-stored screens comprising a graphical representation how the cut of a gemstone affects its light handling ability, and a user interface screen. The user interface screen allows the user to control the operation of the apparatus to measure the one or more optical properties of a particular gemstone provided to the apparatus, to view an image of the gemstone measured, and to view representations of the measured one or more optical properties.

A system of construction that uses a discrete repertoire of elastic modular units that interconnect forming assemblies of diverse curved geometries applicable at any scale. Each modular unit is formed with linear elements with less than infinite elastic modulus. The modular units connect to one another under tension creating structural networks that have stored elastic potential energy. The linear elements may be formed of carbon based composite materials and their future permutations, including smart materials. The modular assemblies created using this system have application in terrestrial, space and aquatic environments and as an educational tool.
