Rotate the belt tensioner counter-clockwise once again.
Correspondingly, the plane of the pendulum as viewed from above appears to rotate in a clockwise direction once a day.
As reported in the British journal Nature, the researchers cooled the ring to near absolute zero and showed that a current consisting of billions of electrons could be coaxed to spin around it in two directions at once, clockwise and counterclockwise.
The second was turning 48 small pegs a quarter-turn clockwise; and then once that was finished, going back to the beginning and doing another quarter-turn for each peg (and so on).
In the ordinary world, a current in such a loop can flow in only one direction at once, either clockwise or anti-clockwise.
Because of weird quantum effects, current flow through the circuit can be in superposition: The current is, in effect, flowing clockwise and counterclockwise at once.
They include these images, clockwise from top left: "Once There Were Jews Here" by Karin Meyers; "Untitled" by Arnold Kastenbaum; and three images by Eugenia Ames, "The Covered Car," "The Abandoned Building" and "The White Pony".
Meanwhile, in 2002, Lloyd and Bill Kaminsky, a graduate student in his group, proposed a way to realize an adiabatic quantum computer using superconducting electrical circuits, in which current flow can be in superposition: effectively, the current is flowing clockwise and counterclockwise at once.
Once the clockwise velocity field was established until the peak of the snowmelt runoff in the middle of April, the negative vorticity was retained by the small runoff although the clockwise velocity field gradually weakened because of the spin down.
Most planets also rotate on their axes in an anti-clockwise direction, but Venus rotates clockwise (called "retrograde" rotation) once every 243 Earth days the slowest rotation period of any planet.
(Clockwise from left) RH New York was once home to Pastis, a popular French bistro.
