Geometrically it is the increasing of the square of the scientific researches which means raising to the second degree. It is logically to indicate it as a (As for me, this recalls the exciting associations with the formula of the german Nobel Prize Winner Ervin Schroedinger for the probability density, which is full of poetry and music) Comments: © A.
