Backwards Clock Anti Clockwise Unusual Novelty Joke

Product Information

The best-known surviving example is the Münster astronomical clock, whose hands move counterclockwise. Then, when the Sun moves in the sky (from east to south to west), the shadow, which is cast on the sundial in the opposite direction, moves with the same sense of rotation (from west to north to east). It may be difficult to come up with fun and engaging ways to teach your KS1 and KS2 students about clockwise and anti-clockwise rotation. From expansive spaces like lounges and foyers to the more confined areas such as offices and corridors, there is an anticlockwise clock to fit every setting. There are a number of rather charming superstitions about clockwise and anticlockwise motion; one in Britain was that walking widdershins around a church three times was sufficient to summon the Devil (I haven't had the nerve to give it a shot) and in general moving anticlockwise seems to have been considered unlucky (as an extension to the idea that anything to do with leftward motion is also unlucky; after all, the Latin for left is "sinister" and not for nothing does "right" mean both the direction, and that which is proper or correct).

Curiously, unlike with games, there is usually no objection if turns begin to move counterclockwise. There's nothing to stop the hands of a clock from running backwards — indeed, some actually do — but the overwhelming majority move, well, clockwise. In 2014, for example, the new clock fitted on the building housing Bolivia’s national congress in La Paz was fitted with hands which move in an anti-clockwise direction.

As an alternative to using a clock to describe the rotation of a body, it is possible to use the right/left hand rule to determine the rotation.Clockwise motion (abbreviated CW) proceeds in the same direction as a clock's hands relative to the observer: from the top to the right, then down and then to the left, and back up to the top. The first methods that humans used to measure time were the celestial bodies: the Sun, the Moon and the stars. The reason for the clockwise standard for most screws and bolts is that supination of the arm, which is used by a right-handed person to tighten a screw clockwise, is generally stronger than pronation used to loosen. Before clocks were commonplace, the terms " sunwise" and "deasil", "deiseil" and even "deocil" from the Scottish Gaelic language and from the same root as the Latin "dexter" ("right") were used for clockwise. Backwards time travel, by the way, actually seems to be permissible in relativity theory; there are certain solutions to its equations that are "closed timelike curves," the traversing of which would be equivalent to backwards time travel.

Why is there no period in history where anticlockwise and clockwise rotation competed for supremacy? Following onto Year 2, by then students should be able to understand these turns and which direction they are going in, clockwise or anti-clockwise. The first mechanical clocks did not start appearing in Europe until around the start of the 14 th century. At its simplest a sundial consists of a plate and a gnomon, usually a triangular blade, whose purpose is to cast the shadow of the sun. Children who are in Year 6 need to rotate shapes through 90˚ or 180˚ either clockwise or anti-clockwise.A universe in which it can't happen is a much tidier one; backwards time travel has the potential to produce nasty paradoxes. By the time countries in the southern hemisphere began to consider designing clocks, their time to impose the way the shadow of the sun appears to move over their skies as the gold standard for clock movement had long passed. What this means is that while the shadow cast by the gnomon reflects the apparent motion of the sun through the sky, it is represented as travelling in the opposite direction, from west through north to east. Some gas fittings are left-handed to prevent disastrous misconnections: oxygen fittings are right-handed, but acetylene, propane, and other flammable gases are unmistakably distinguished by left-handed fittings.
