In mathematics, quaternions are a non-commutative number system that extends the complex numbers.Quaternions and their applications to rotations were first described in print by Olinde Rodrigues in all but name in 1840, [1] but independently discovered by Irish mathematician Sir William Rowan Hamilton in 1843 and applied to mechanics in three-dimensional space.
Clinton Eastwood Jr. (born May 31, 1930) is an American actor and film director. After achieving success in the Western TV series Rawhide, Eastwood rose to international fame with his role as the "Man with No Name" in Sergio Leone's Dollars Trilogy of spaghetti Westerns during the mid-1960s and as antihero cop Harry Callahan in the five Dirty Harry films throughout the 1970s and 1980s.

The Quaternion Society was a scientific society, self-described as an "International Association for Promoting the Study of Quaternions and Allied Systems of Mathematics". At its peak it consisted of about 60 mathematicians spread throughout the academic world that were experimenting with quaternions and other hypercomplex number systems.
The walk was launched in 1990 by Prof Tony O'Farrell of the Department of Mathematics at St Patrick's College, Maynooth. [3] It starts at DIAS Dunsink Observatory, where Hamilton lived and was the Director from 1827 to 1865, and ends at the spot where he recorded his discovery by carving the following equation on Broom Bridge: [4]
Alexander McAulay (9 December 1863 – 6 July 1931) was the first professor of mathematics and physics at the University of Tasmania, Hobart, Tasmania.He was also a proponent of dual quaternions, which he termed "octonions" or "Clifford biquaternions".

Of the actors who had previously played Quatermass, only Keir and Mills were still alive; Keir took the role, his final professional performance before his death the following year. [53] The Quatermass Memoirs was repeated several times on digital radio station BBC7 from 2003, and the serial was released on CD in 2006.
