This transition led to the prevalent adoption of the right-hand rule in the contemporary contexts. Following a substantial debate, the mainstream shifted from Hamilton's quaternionic system to Gibbs' three-vectors system. ![]() Josiah Willard Gibbs recognized that treating these components separately, as dot and cross product, simplifies vector formalism. In the context of quaternions, the Hamiltonian product of two vector quaternions yields a quaternion comprising both scalar and vector components. William Rowan Hamilton, recognized for his development of quaternions, a mathematical system for representing three-dimensional rotations, is often attributed with the introduction of this convention. The right-hand rule dates back to the 19th century when it was implemented as a way for identifying the positive direction of coordinate axes in three dimensions. In geometry, a Cartesian coordinate system (UK: / k r t i zj n /, US: / k r t i n /) in a plane is a coordinate system that specifies each point uniquely by a pair of real. Four points are marked and labeled with their coordinates: (2, 3) in green, (3, 1) in red, (1.5, 2.5) in blue, and the origin (0, 0) in purple. In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.
