From hidden figures to musings on how birds fly, Leonardo da Vinci’s notebooks have long been known as treasure troves of art and science. And it turns out that, 500 years after the master doodled in ...

Chemists and engineers have discovered a fundamental friction law that is leading to a deeper understanding of energy dissipation in friction and the design of two-dimensional materials capable of ...

CAMBRIDGE, England, July 22 (UPI) --Scribbled pages in a notebook of Leonardo da Vinci, previously dismissed as nonsense, have been revealed as the polymath's earliest musings on the laws of friction.

Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in wet ...
