WebNov 3, 2024 · In the paper Hamilton's Discovery of Quaternions by B. L. VAN DER WAERDEN, the author lists the criteria Hamilton was looking to satisfy from his algebra: They must define a finite-dimensional unital algebra over R. This led him to adopt the notation a + b i + c j for the elements of such an algebra. In mathematics, the quaternion number system extends the complex numbers. Quaternions were first described by the Irish mathematician William Rowan Hamilton in 1843 and applied to mechanics in three-dimensional space. Hamilton defined a quaternion as the quotient of two directed lines in a three … See more Quaternions were introduced by Hamilton in 1843. Important precursors to this work included Euler's four-square identity (1748) and Olinde Rodrigues' parameterization of general rotations by four parameters (1840), but neither … See more Conjugation of quaternions is analogous to conjugation of complex numbers and to transposition (also known as reversal) of elements of Clifford … See more The vector part of a quaternion can be interpreted as a coordinate vector in $${\displaystyle \mathbb {R} ^{3};}$$ therefore, the … See more Quaternions are also used in one of the proofs of Lagrange's four-square theorem in number theory, which states that every nonnegative integer is the sum of four integer squares.
