Close up we see pistons move up and down or side to side. Pendulums sway, the small parts of machinery move. Gears drive larger wheels. Gears within gears spin. Shafts turn some mechanism that is out ...

First-principles methods, particularly density functional theory, have become indispensable for probing the fundamental origins of mechanical resilience and electronic behaviour in crystalline ...

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 with ...
