... Definition 2 An energy tensor M represents a state of pure radiation (at a point) when the whole energy density is radiated as Poynting energy, ρ = |s⊥ |. An energy tensor M represents a state of asymptotic pure radiation (at a point) when ρ 6= |s⊥ | and for any positive real number ǫ one can find a ...

... and then glow the amount of LED’s which have been embedded in the systems. For the light conditions of 0-225 we need all the 4 LED’s tro be glowing while for light condition of the range of 225-450 there is a need for 2 LED’s to be glowing. This requirement of LED’s is further reduced if more of the ...

Einstein`s Theory of Gravity
... • Since the source of the gravitational field is a tensor (Tµν ) the field should be also described by a 2nd order tensor e.g. Fµν . • Since the role of the gravitational potential is played by the metric tensor then Fµν should be a function of the metric tensor gµν and its 1st and 2nd order derivat ...
