Cotton thread is made of many tiny fibers, each just 2-3 cm long, yet when spun together the fibers are capable of transmitting tension over indefinitely long distances. From a physics perspective, how threads and yarns transmit ...
Optical fibers are now delivering ultrafast internet connections to homes across the world. By replacing electronics-based technologies with architectures that process pulses of light, a similar leap in speed might also be ...
