The upper figure shows the viscoelastic toy model proposed here, characterized by only six independent parameters. Surprisingly, this simple mechanical model produces complicated system dynamics, as ...

Opinion polarization is often considered as the primary driver of social friction, leading to exhaustive efforts to force a consensus. However, new research suggests a more pragmatic goal: reducing ...

Friction, though familiar in everyday life, remains a complex phenomenon—especially at the microscopic level. Scientists long believed it arose from rough surfaces rubbing together, where tiny bumps ...
