To ensure reality of interaction processes in a continuous medium, it is indispensable to have both a positive source ejecting the medium (the radiant) and a negative source sucking the ambient medium (the sink). Whereas the positive source (radiant) in the medium is implemented easily by the flow reflection from the obstacle (body), the negative source (sink) can hardly be implemented without special techniques. One of the solutions may be found in nature. To meet condition (3), we have to stop propagation of the medium (q=0) towards the center of the source by directing the lateral area flow Q transversely to the source radius, i.e. at a tangent to the circumference converting it to a flow rotating around the source axis thereby producing a vortex. evgars(punktumcom/berdinskih

time goes fast for bugs maybe therefore its scary

therfore maybe until then

will you yes i can

empty full tank of yes

no i will do it yes

yesno
