comment Is there any case in physics where the equations of motion depend on high time derivatives of the position?
Any other classical (or non-classical) problems involving jerk?

comment Is this a Fata Morgana?
@PeterShor It was taken in Israel, the coast of the Mediterranean sea, around September.

How's that this layer of clouds have such a uniform height above the horizon? I would expect that when clouds appear more dense near the horizon they'll go from sparse to dense in a more gradual transition than seen here. I see a lot of similarity in the uniform height of the layer to that seen in superior mirages, like here.

Maybe Fata Morgana is a wrong name for this phenomena. I think that superior mirage is more adequate. If this dark layer is because of light diffraction by clouds as you suggested, why its boundary is so sharp and at such a uniform height above the horizon? I would expect the change in the brightness to be more gradual.

comment Dark and bright areas around atoms in a scanning tunnelling microscope image
I'm interested in the probability density $|\Psi(\mathbf{r}, t)|^2$ of finding an atom at a given position. Is it possible that the atoms are pretty well localized in space, and yet we will see those wave-like patterns in the STM image, e.g. a quantum mirage inside a quantum corall?

comment Dark and bright areas around atoms in a scanning tunnelling microscope image
Is it because the atoms themselves aren't localized to a specific location, or is it because their electron cloud exhibits wave properties? In the first case, I would expect that using atoms with heavier nucleus (at the same temperature) will reduce this effect. Moreover, aren't the CO molecules that have been used by IBM have enough momentum at this temperature so that their position could be regarded as a position of a classical object?

OK than, thanks.
