@j_bertolotti On the plane are they just uniform or hyperuniform?

[Diego Di Battista @diegus841]

@WFShaping And not on the quality of her/his science

[Diego Di Battista @diegus841]

@WFShaping Cause It might depend on how good he/she is in shaking hands

How lightinings appear from our orbit? Glad to be part of this challenging project.

@romolo_savo @cref_official Grande Romolo, sono contento per te. Ci vediamo a Roma

@LucaBizzarri Cosa - sóla.

@valeriolundini A Roma se fa solo 'a pizza ar taglio, tutto er resto so robba de risvortini, monopattini e mocassini.

@j_bertolotti In my opinion the problem is not in the average itself, but in the assumption we make to belong to a Normal Distribution. It is not always normal to be in Normal as for the N-1 case

Lightning Imager, #Leonardo’s lightning detector, has been shipped from Campi Bisenzio to @Thales_Alenia_S plant in France where it will be integrated on the first Meteosat Third Generation satellite to hunt for lightning. Find out more: https://t.co/OyhBjrCclL

@MCherkashin @JamesDManton Said that, I see on this thread much more authoritative expert in the field than I do. I am sure you can find more precise explanations reading through their articles and book chapters.Happy new year Maxim

[Diego Di Battista @diegus841]

@MCherkashin @JamesDManton Yes and not, the light is, indeed, reflected by less uneven surface but it is not really matter of angular distribution. I like to interpret the problem as follows here below, although it might not be super faithful with the exact theory:

[Diego Di Battista @diegus841]

@MCherkashin @JamesDManton It follows that the combination of several element mixed up (tends to randomise, if you like better) the pattern on the screen, then the speckle grains are smaller.

[Diego Di Battista @diegus841]

@MCherkashin @JamesDManton On the contrary, when the reflected spot is larger, the amount of light reflected is the same (as in the previous) but a lot of portions of light has "experienced" very different roughness. Then, in this case, the reflected field can be decomposed into very numerous elements.

[Diego Di Battista @diegus841]

@MCherkashin @JamesDManton The small spot reflects a lot of light that has experienced very similar roughness, then this light can be decomposed into a few elements of an orthonormal basis. Each point on the screen (optical bench surface) is the result from the combination of these independent components.
