‎First printing of Gross's important paper including ""The Gross Tranformation"" on cosmic rays which relates the absorption of isotropic and unidirectional beams of radiation. ""Using this transform one can obtain the vertical intensity of a certain radiation per unit solid angle at a certain atmospheric depth in terms of the integral (omnidirectional) rate of that radiation at this depth. He applied this relation to cosmic radiation."" (Dobrigkeit, Cosmic Ray Physics in Brazil. P. 3).There is however, a consequence into this fkgmghncsdlfgmmvgnv,slffmck‎
