Cosmic filaments are among the largest structures in the Universe, and they rotate. In a new study that stacked thousands of filaments together, they were observed to be rotating along their ...

Twisted light: self-torque could be used to manipulate molecules. (Courtesy: iStock/VikaSuh) Physicists in Spain and the US have shown that the orbital angular momentum, or twistedness, of light can ...

Can we improve performance by adding control elements external to the PID loop? Yes. Here we consider torque control and the related subject of torque feedforward — which can make systems run more ...
