2010/11/29
Size-resolved vertical aerosol number fluxes of particles in the diameter range 0.25–2.5 μm were measured with the eddy covariance method from a 53 m high tower over the Amazon rain forest, 60 km NNW ...
Acceleration of particles by black holes -- general explanation
Acceleration of particles black holes -- general explanation
font style='font-size:12px;'>
2010/12/17
We give simple and general explanation to the effect of unbound acceleration of particles by black holes. It is related to the fact that the scalar product of a timelike vector of the four-velocity of...
