On the basis of postulates for the holographic description of gravity and the introduction of entropic force, for static sources we derive the universal law: the entropy of a holographic screen is equal to quarter of its area in the Planck system of units. The ideas offered by Verlinde in [15] have generated wide discussions and investigations, wherefrom we can mention applications to cosmology [20][21][22][23][24][25][26][27][28][29][30][31][32], entropic corrections to the Newton's law of gravity [33][34][35][36][37][38], interpretations in terms of Rindler horizon [39][40][41][42], study of specific gravitational systems [43][44][45], relations with Loop Quantum Gravity [46-48] and a specific microscopic justification of bits on the surface [49].
