  2. Clockwise - Wikipedia

    en.wikipedia.org/wiki/Clockwise

    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 opposite sense of rotation or revolution is (in Commonwealth English ) anticlockwise ( ACW ) or (in North American English ) counterclockwise ( CCW ...

  3. Right-hand rule - Wikipedia

    en.wikipedia.org/wiki/Right-hand_rule

    When viewed at a position along the positive z-axis, the ¼ turn from the positive x-to the positive y-axis is counter-clockwise. For left-handed coordinates, the above description of the axes is the same, except using the left hand; and the ¼ turn is clockwise. Interchanging the labels of any two axes reverses the handedness.

  4. Curve orientation - Wikipedia

    en.wikipedia.org/wiki/Curve_orientation

    Otherwise, that is if left and right are exchanged, the curve is negatively oriented or clockwise oriented. This definition relies on the fact that every simple closed curve admits a well-defined interior, which follows from the Jordan curve theorem .

  5. Orientability - Wikipedia

    en.wikipedia.org/wiki/Orientability

    A torus is an orientable surface The Möbius strip is a non-orientable surface. Note how the disk flips with every loop. The Roman surface is non-orientable.. In mathematics, orientability is a property of some topological spaces such as real vector spaces, Euclidean spaces, surfaces, and more generally manifolds that allows a consistent definition of "clockwise" and "anticlockwise". [1]

  6. Clock position - Wikipedia

    en.wikipedia.org/wiki/Clock_position

    A clock position, or clock bearing, is the direction of an object observed from a vehicle, typically a vessel or an aircraft, relative to the orientation of the vehicle to the observer. The vehicle must be considered to have a front, a back, a left side and a right side.

  7. Optical rotation - Wikipedia

    en.wikipedia.org/wiki/Optical_rotation

    Dextrorotation and laevorotation (also spelled levorotation) [1] [2] in chemistry and physics are the optical rotation of plane-polarized light.From the point of view of the observer, dextrorotation refers to clockwise or right-handed rotation, and laevorotation refers to counterclockwise or left-handed rotation.

  8. Cardinal direction - Wikipedia

    en.wikipedia.org/wiki/Cardinal_direction

    Medieval Scandinavian orientation would thus have involved a 45 degree rotation of cardinal directions. [5] north (Proto-Germanic *norþ-) from the proto-Indo-European *nórto-s 'submerged' from the root *ner-'left, below, to the left of the rising sun' whence comes the Ancient Greek name Nereus. [6] east (*aus-t-) from the word for dawn.

  9. Sinistral and dextral - Wikipedia

    en.wikipedia.org/wiki/Sinistral_and_dextral

    The terms are derived from the Latin words for "left" (sinister) and "right" (dexter). Other disciplines use different terms (such as dextro-and laevo-rotary in chemistry, or clockwise and anticlockwise in physics) or simply use left and right (as in anatomy). Relative direction and chirality are distinct concepts.
