Title: Geometrical Applications of Split Octonions

Geometrical applications of split octonions is considered. Eight real parameters characterizing physical signals are related to space-time coordinates, to the classical action and to the wavelengths.

Representation of rotations by split octonions (active transformations of basis units) lead to the real non-compact form of Cartan's group G2.

Elementary particles are connected with zero divisors, the elements which nullify octonionic intervals.

In front of time-like coordinates in the expression of pseudo-Euclidean intervals naturally appear two fundamental physical parameters, the light speed and Planck's constant.

From the requirement of positive definiteness of norms under G2-transformations, together with the introduction of the maximal velocity, there follow uncertainty relations.
