Bits, bytes and silicon transistors? Boy, you have it good -- back in 1953, state-of-the-art computers were made of gears, sprockets, chains and cams, and we trusted them to accurately wreck lives ...

First-principles calculations, rooted in quantum mechanics and executed without recourse to empirical parameters, provide a robust framework for predicting the mechanical and thermodynamic properties ...

Figure 1. (click to enlarge) Available in tape or rod form, carbon-fiber composites are increasingly being used in place of metals for implants. The basic mechanical principles behind implants used ...
