comment Gedankenexperiment to derive the Robertson uncertainty relation without confusing it with the obersver effect
@JánLalinský It's part of the curriculum and I don't want to make the ideas too wrong (for example by confusing the Robertson relation with the noise-disturbance relation...)!

@Martin I guess this will be mathematically to advanced for high school level.

comment Conservation of energy and momentum in photoelectric effect
Ok, so the $\phi$ represents that the solid takes some part of the energy to fulfill energy conservation. But how would be the equation for the momentum conservation?

comment Visually appealing ways to plot singular vector fields with matplotlib or other foss tools
Nice picture. Can you share your source code? Though matlab is not free software, one might be able to translate this to free software tools, if one has the source code. By the way: The vector field doesn't seem singular to me.

comment Visualize singular vector fields with TikZ or PsTricks and friends
Nice. What's missing is some type of color map for the field lines and (or) the equipotential lines to indicate the field strength. Is it also possible to get the vector field plot and not the field lines?
