[edit] Appropriation of nomenclature

W.K.Clifford wrote the following footnote to justify use of the term biquaternion:

Hamilton's biquaternion is quaternion with complex coefficients; but it is convenient (as Prof. Pierce remarks) to suppose from the beginning that all scalars may be complex. As the word is no longer wanted in its old meaning, I have made bold to use it in a new one.(footnote pp. 188-9)

Actually the word is wanted in its old meaning. Rgdboer 20:54, 14 April 2006 (UTC)

[edit] Move explained

The term "Clifford biquaternion" is used for both dual quaternions (see Rooney) and for the split-biquaternion ring. This ambiguity is being divided by the natural inclusion of the descriptor (split or dual) of the coefficient ring in each case.Rgdboer (talk) 01:25, 30 March 2008 (UTC)
