1. When your muscles contract it is largely because many C–C sigma (single) bonds
   are undergoing rotation (conformational changes) in a muscle protein called
   myosin (肌蛋白質、肌球素).


2. When you etch glass with a diamond, the C–C single bonds are resisting all the
   forces brought to bear on them such that the glass is scratched and not the
   diamond.
