Explore the critical angle condition that determines the motion of a spool under applied force. This physics problem breaks down the concepts step by step, explaining when the spool rolls forward, ...

One of the concepts within vehicle dynamics that is often misunderstood, but vital in terms of gaining a competitive edge, is slip angle. Imagine taking a corner at speed on a track. There is a moment ...

Emergence of anti-hyperuniform defect organization in active nematics. At high activity (left), topological defects are distributed nearly uniformly throughout the system. Reducing activity toward a ...

In addition to finding total rare-earth oxide and yttrium grades ranging from 0.40% to 0.47%, with heavy rare-earth oxides representing approximately 26% to 27% of the total rare-earth oxides and ...

An obscure theory of elementary particles proved to be key to China’s re-emergence as a scientific nation after the Cultural Revolution had stalled its development. Robert P Crease finds out more from ...
