Naples [ ]— counterclockwise; that is, when they move.
Unfortunately, there is a shortage of benches on which to pass the resulting time, but at least the wait provides a soothing prelude to the decidedly non-dull Naples traffic.
Arch adds that the carousel runs quite silently, and that there is another belt for oversize luggage, which is not a carousel, but many seem to spend a lot of time watching it.

Technically, the terms clockwise and counterclockwise can only be applied to a rotational motion once a side of the rotational plane is specified, from which the rotation is observed.
For example, the daily rotation of the Earth is counterclockwise when viewed from the North Pole, and clockwise when viewed from the South Pole.
Typically, screws and bolts are loosened (moved towards the observer) counterclockwise and tightened (moved away from the observer) clockwise, in accordance with the right-hand rule.

 Motor driven shutter activated by single motor having controllable clockwise and counterclockwise rotations - Patent ...
On the other hand, the opening lever 7 is turned counterclockwise resisting the bias of the spring 7d because the control portion 7a is pushed by the cam portion 3c, and activates the pin 8 to close the shutter blades which are in an open state.
When the step motor 1 further rotates counterclockwise, the closing lever 10 is turned clockwise resisting the bias of the spring 10d because the control portion 10c is pushed by the cam portion 3d and activates the pin 11 to open the diaphragm blades which are in a closed state.
When the motor M rotates counterclockwise corresponding to either signal of the balb mode or time mode, the stepped portion 3f retreats from the pin 10a and the closing lever 10 is rapidly turned by the spring 10d, closing the shutter blades and ending the exposure.

Usually, when one pulls the plug in the bathroom sink the water tends to be moving either clockwise or counterclockwise.
As the water moves toward the drain, the preexisting clockwise or counterclockwise motion is enhanced because of a law of physics that requires the circular motion to be maintained.
However, if the water is perfectly still and there is no disturbance as the drain is opened, the water should tend to develop a counterclockwise flow pattern as it drains away in the northern hemisphere, and a clockwise pattern if it drains in the southern hemisphere.

 Electrophysiological determinant for induction of isthmus dependent counterclockwise and clockwise atrial flutter in ...
The short stimulus to onset of the ECG flutter wave interval in both situations indicates that the coronary sinus ostium was the exit of the slow conduction zone in counterclockwise atrial flutter and the low lateral right atrium was the exit in clockwise atrial flutter.
The cycle length of the counterclockwise atrial flutter (A) was 226 ms, and that of the clockwise atrial flutter (B) was 217 ms.
Note the abrupt unidirectional block between Halo 1 and Halo 10 (that is, the isthmus zone) and the initiation of clockwise atrial flutter (cycle length 224 ms) after repenetration of the right atrial wavefront from the coronary sinus ostium end to the LLRA end of the isthmus.

 Language Log: Westward on the eastbound shuttle; or, what a long strange trip that would be
The idea that you can distinguish a clockwise from a counter-clockwise circular loop by saying that one goes to the west and the other doesn't is more than just wrong, it's a screamingly obvious geometrical impossibility.
John Cowan noted that "left" and "right" are conceptually linked with "counterclockwise" and "clockwise", respectively, and with "west" and "east", respectively.
Most contemporary ceiling fans have a switch that toggles between clockwise and counterclockwise motion; the counterclockwise direction pushes air down (for getting a breeze in warmer months) and the clockwise direction draws air up (which in turn pushes the warmer air down in colder months).

When you specify an arc using the Angle option, again there are two possible arcs, one drawn counterclockwise and one drawn clockwise.
To draw the arc clockwise, use a negative number for the angle.

 Clockwise vs Counterclockwise : Fool Moon   (Site not responding. Last check: 2007-10-26)
I visualize a tall glass panel with a transparent clock on it, and the hands are moving quite rapidly in a clockwise direction.
Clockwise or counter-clockwise depends on which side of the clock we are staring at, the hands are always making their sacred circle, we are the ones who impose the concept of "direction" on the motion, and we are the ones who associate qualities with the direction we perceive.
Personally I would link clockwise (which only came into play as a concept once there were clocks, or was it sundials?) with righthandedness, dextrousity, "rightness".

 Clockwise or counterclockwise polygon in a plane   (Site not responding. Last check: 2007-10-26)
For the more general case where the polygons may be convex, it is necessary to consider the sign of the cross product between adjacent edges as one moves around the polygon.
There are pathological cases to consider here as well, all the edges cannot be colinear, there must be at least 3 vertices, the polygon must be simple, that is, it cannot intersect itself or have holes.
Example and test program for testing whether a polygon is ordered clockwise or counterclockwise.

The seeds of a flower head form interlocking spirals in both clockwise and counterclockwise directions.
The number of clockwise spirals differs from the number of counterclockwise spirals, and these two numbers are called the plant's parastichy numbers (pronounced pi-RAS-tik-ee or PEHR-us-tik-ee).
Buds 0, 13, and 26 form a clockwise spiral and buds 0, 8, 16, 24, and 32 form a counterclockwise spiral.

Professor Philippe Cluzel at the Materials Research Center at the University of Chicago, and his collaborators would offer a resounding "yes!" Their laboratories have recently demonstrated that the patterns of clockwise and counterclockwise rotations of an individual bacterial tail, over time, reflect changes in molecular environment.
Counter-clockwise rotations of the tail cause the bacteria to swim in a straight line, whereas clockwise rotations of the tail causes it to "tumble" by initiating a change in direction.
First, the fluctuations between clockwise and counterclockwise tail rotation is attributable to the chemical signalling network itself.

 The Straight Dope: Do bathtubs drain counterclockwise in the Northern Hemisphere?
The erroneous bit of folk wisdom you refer to says that water always drains in a clockwise direction in the Southern Hemisphere, and in a counterclockwise direction in the Northern Hemisphere.
However, when you get down to itty-bitty phenomena such as the water draining out of your bathtub, the Coriolis effect is insignificant, amounting to roughly three ten-millionths of the force of gravity (in Boston, at least, which is where they happened to do the measuring).
When the plug was pulled after four to five hours, the water started draining clockwise, then gradually slowed down and finally started swirling in the opposite direction.
