    Welcome to my homepage. I am a postdoctoral research fellow in theoretical particle physics at the University of Cambridge. My research is supported by the Walter Grant Scott Research Fellowship in physics at Trinity Hall. My main interests are division algebras, Clifford algebras, Jordan algebras, and their relation to particle physics.

Excerpt from Octonions: A Development of Clifford's Bi-Quaterions I owe a great debt of gratitude to an old pupil for the results of a casual conversation I had with him some six or seven years by: 6. FROM a purely formal point of view, apart from any question of geometrical or physical application, the mathematical method known as quaternions may be described Octonions a system of shorthand for dealing with the algebra of certain complex numbers.

By this I mean that they do not depend in any way on an arbitrarily chosen system of axes or arbitrary origin. But one of the two quaternions implied by Clifford's term does so depend on an arbitrary origin.

This. The biquaternions form an example of a quaternion algebra, and it has norm (,) = + + +. Two biquaternions p and q satisfy () = () indicating that N is a quadratic form admitting composition, so that the biquaternions form a composition algebra.

The philosophical perspective, the technical language, and the notation. changes as quaternions evolve into Grassmann algebras and into the theory. of non-commutative complex rotational groups, so following the historical. development is especially challenging in the absence of a source by: 2.

In ring theory, dual quaternions are a ring constructed in the same way as the quaternions, except using dual numbers instead of real numbers as coefficients. A dual quaternion can be represented in the form p + ε q, where p and q are ordinary quaternions and ε is the dual unit (which satisfies εε = 0).

This book investigates the geometry of quaternion and octonion algebras. Following a comprehensive historical introduction, the book illuminates the special properties of 3- and 4-dimensional Euclidean spaces using quaternions, leading to enumerations of the corresponding finite groups of symmetries.

The second half of the book discusses the less familiar octonion algebra, concentrating on its. Cayley’s (which are now called “octonions,” x ∈ O), or to Clifford’s (which are in a way an anticipation of Penrose’s “twistors”). 2 MATH-VARIA The books by W.R. Hamilton, P.G. Tait, and C.J. Joly listed in this section also contain chapters or sections on the applicationsof quaternions to classical physics.

Clifford developed the theory of biquaternions (a generalization of the Irish mathematician Sir William Rowan Hamilton’s theory of quaternions) and then linked them with more general associative algebras.

He used biquaternions to study motion in non-Euclidean spaces and certain closed Euclidean manifolds (surfaces). In McAulay published, through Cambridge University Press, his Octonions: a Development of Clifford's Biquaternions.

McAulay died on 6 July His brother Francis Macaulay, who stayed in England, also contributed to ring theory. The University of Tasmania has commemorated the McAulays' contributions in Winter Public al advisor: Ernest Rutherford.

Q: Quaternions and Octonions: what. Posted on Febru by The Physicist Physicist: The most straightforward way to stumble across quaternions is to sit around thinking about complex numbers, where we have “i” which is the square root of -1 and stands for “imaginary number”. Octonions are a superset of quaternions in the same way that quaternions are a superset of complex numbers McAulay A.

Octonion Value Operations. He invented the Clifford algebras, of which octonions and biquaternions are special cases. He published his ideas in On the Space-Theory of Matter (), as well as the book of children's tales The Little People, but died at the peak of his creativity.

This book is about the beasts I selected for attention (if you will, to ren­ der this metaphor politically correct, let's say I was a nature photographer), and the kind of tools I had to develop to get the kind of shots Iwanted (the tools that I found there were for my taste overly abstract and theoretical).

$\begingroup$ You don't need a book on Clifford/ geometric or Lie algebras. Quaternions are only a small part of those topics. If you'd like to really use quaternions and understand exactly how and why they work then studying geometric algebra can help, but if you just want to be able to read Maxwell's treatise you should look at the way that quaternions were be used at that time -- possibly.

A split-biquaternion is a member of the Clifford algebra Cℓ 0,3 (R). This is the geometric algebra generated by three orthogonal imaginary unit basis directions, {e 1. (Note that the z here occurring is only required to ensure harmony with tri-quaternions of which our present biquaternions, as also octonions, are particular cases.) The point whose position vector is Vrq i is on the axis and may be called the centre of the bi-quaternion; it is the centre of a sphere of radius Srq i.

The standard model of particle physics is the result of decades of collaboration, which began roughly in the s, and converged finally on its current state in[ 1 ]. It is a perfected set of rules that tells us how the known fundamental particles behave.

In the decades sincethe standard model has seen little in the way of. He had already published Utility of Quaternions in Physics () and Octonions: A Development of Clifford's Biquaternions (). With Professor E. Hogg, McAulay carried out a magnetic survey of Tasmania in A preliminary sketch of biquaternions.

Octonion. Quite the same Wikipedia. Just better. Most off-diagonal elements of the table are antisymmetric, making it almost a skew-symmetric matrix except for the elements on the main diagonal, as well as the row and column for which e 0 is an operand. The table can be summarized as follows: = {, =, = − +, where is the Kronecker delta and is a completely antisymmetric tensor with value +1.

In octonions the analogue of Hamilton's vector is localized to the extent of being confined to an indefinitely long axis parallel to itself, and is called a rotor; if p is a rotor then wp is.

Yet Clifford is now best remembered for his eponymous Clifford algebras, a type of associative algebra that generalizes the complex numbers and William Rowan Hamilton's quaternions.

The latter resulted in the octonions (biquaternions), which he employed to study motion in non-Euclidean spaces and on certain surfaces, now known as Klein-Clifford.

The term hypercomplex number harkens back to the age of steam. For the most part, the hypercomplex systems have been assimilated through the resolution of vision provided by groups, rings, and fields, and the term has been retired from use.
