All currents are circular when you zoom out far enough, and are driven by inequalities in energy. Inequalities in thermal energy, for wind, and wind energy, for waves. Inequalities in voltage drive electrical current, which is remarkable fluid like, in its behavior.
I thought the US government had a policy against paying ransoms. But we did it with the basketball player in Russia, too
This will come back to haunt us because it clearly communicated to terrorist organizations (even if they are governments of foreign nations) that the US will pay you if you threaten enough citizens.
Where does an ocean wave start?
