quaternion
n 1: the cardinal number that is the sum of three and one [synonym:
{four}, {4}, {IV}, {tetrad}, {quatern}, {quaternion},
{quaternary}, {quaternity}, {quartet}, {quadruplet},
{foursome}, {Little Joe}]

Quaternion \Qua*ter"ni*on\, v. t.
To divide into quaternions, files, or companies. --Milton.
[1913 Webster]


Quaternion \Qua*ter"ni*on\, n. [L. quaternio, fr. quaterni four
each. See {Quaternary}.]
1. The number four. [Poetic]
[1913 Webster]

2. A set of four parts, things, or person; four things taken
collectively; a group of four words, phrases,
circumstances, facts, or the like.
[1913 Webster]

Delivered him to four quaternions of soldiers.
--Acts xii. 4.
[1913 Webster]

Ye elements, the eldest birth
Of Nature's womb, that in quaternion run. --Milton.
[1913 Webster]

The triads and quaternions with which he loaded his
sentences. -- Sir W.
Scott.
[1913 Webster]

3. A word of four syllables; a quadrisyllable.
[1913 Webster]

4. (Math.) The quotient of two vectors, or of two directed
right lines in space, considered as depending on four
geometrical elements, and as expressible by an algebraic
symbol of quadrinomial form.
[1913 Webster]

Note: The science or calculus of quaternions is a new
mathematical method, in which the conception of a
quaternion is unfolded and symbolically expressed, and
is applied to various classes of algebraical,
geometrical, and physical questions, so as to discover
theorems, and to arrive at the solution of problems.
--Sir W. R. Hamilton.
[1913 Webster]

  • Quaternion - Wikipedia
    In mathematics, the quaternion number system extends the complex numbers Quaternions were first described by the Irish mathematician William Rowan Hamilton in 1843 [1][2] and applied to mechanics in three-dimensional space
  • Introducing The Quaternions - Department of Mathematics
    Take any unit imaginary quaternion, u = u1i + u2j + u3k That is, any unit vector
  • Quaternion -- from Wolfram MathWorld
    The quaternions are members of a noncommutative division algebra first invented by William Rowan Hamilton
  • What Is a Quaternion? The Math Behind 3D Rotation
    A quaternion is a number with four components: one real part and three imaginary parts Written out, it looks like q = w + xi + yj + zk, where w, x, y, and z are ordinary real numbers, and i, j, and k are three distinct “imaginary” units
  • Quaternions: what are they, and why do we need to know?
    quaternion into a ‘scalar’ and a ‘vector’ part For a few decades, quaternions were used in physics to represent spa ial quantities, often with the scalar part set to zero Maxwell
  • Quaternion | Rotations, Hypercomplex Numbers, Algebra | Britannica
    Quaternion, in algebra, a generalization of two-dimensional complex numbers to three dimensions Quaternions and rules for operations on them were invented by Irish mathematician Sir William Rowan Hamilton in 1843
  • Lecture 5. Quaternions - Stony Brook University
    A quaternion of the form 0 + bi + cj + dk, where b; c; d 2 R is called pure imaginary If q = a + bi + cj + dk is any quaternion, then a is called its scalar part or real part and denoted by Re q and bi + cj + dk is called its vector part and denoted by Ve q
  • Maths - Quaternions - Martin Baker - EuclideanSpace
    Quaternions form an interesting algebra where each object contains 4 scalar variables (sometimes known as Euler Parameters not to be confused with Euler angles), these objects can be added and multiplied as a single unit in a similar way to the usual algebra of numbers
  • Introduction to Quaternions • RAW
    Quaternions are based on Euler’s rotation theorem, which states that a relative orientation of two coordinate systems can be described by the rotation about a single rotation axis Quaternions were also adapted in physics For example, Maxwell’s equations were originally formulated with quaternions
  • 1. 2: Quaternions - Mathematics LibreTexts
    The quaternions, discovered by William Rowan Hamilton in 1843, were invented to capture the algebra of rotations of 3-dimensional real space, extending the way that the complex numbers capture the algebra of rotations of 2-dimensional real space
