Quaternions and spatial rotation of a circle representing a particular rotation angle will be half of the angle represented by that rotation, since as the point is moved from the north to south pole, the latitude ranges from zero to 180 degrees, while the angle of rotation ranges from 0 to 360 degrees. (the "longitude" of a point then represents a particular axis of rotation.) Note however that this set of rotations is not closed under composition. Two successive rotations with axes in the "xy" plane will not necessarily give a rotation whose axis lies in the "xy" plane, and thus cannot be represented
38 Degrees comes from the speed with which 38 Degrees can launch a campaign or find out members' views. Campaigning techniques include both online methods, such as mass email, social media, blogs and online petitions, and offline methods, such as calling an MP or visiting a surgery. 38 Degrees has also fundraised from its membership to commission legal advice and to run advertising campaigns. 38 Degrees 38 Degrees is a British not-for-profit political-activism organisation.
