Why does a magnetic mirror acting on ballistic electrons not violate the 2nd law of thermodynamics?

Magnetic mirrors are well known in plasma physics. In order to work, the mean free path of the charge carriers has to be at least as long as the helical paths under the influence of the B field....

Is there a (dis-)advantage in dicotomizing Likert data?

Given there is some k-step (k=3 or 5 or 7 etc) Likert data with "absolutely no" on one side, "absolutely yes" on the other side, and "neutral" in the middle. A correct way to analyze such...

Magnetic monopole pairs generated by photon/photon collisions?

The transformation of two "colliding" photons into a pair of particle / anti-particle was experimentally observed already. But the observed particles are always electrically charged. 1. If such a...

Is it correct to call lo(w)ess "non-parametric"?

It's a weighted least-squares polynomial regression, so it's based on assuming normal errors, and the normal probability model is parametric. However, in some statistics book and online statistics...

Which optical E-field sensor would you recommend for time-domain measurements?

For some years, optical E-field sensors (plus remote units) are commercially available; main advantage: the field is much less disturbed than by electrically conductive sensors. We would like to...
