Spectacle lens design following Hamilton, Maxwell
... The main motivation for this was the need to design multifocal (progressive) lenses for the presbyopic population. The advances in understanding spectacle performance, and the introduction of novel optimization methods enabled also the design of high-quality speciality lenses, such as sport lenses. ...

The ins and outs of conical refraction
... Stripped to their essentials, two versions of conical refraction are shown in figure 2, adapted from Thomas Preston’s Theory of Light (1890) [1]. In both cases a crystal causes a narrow beam of light to develop into a hollow cone, where a pair of rays might be expected from the theory of double refr ...

William Rowan Hamilton
Sir William Rowan Hamilton (midnight, 3–4 August 1805 – 2 September 1865) was an Irish physicist, astronomer, and mathematician, who made important contributions to classical mechanics, optics, and algebra. His studies of mechanical and optical systems led him to discover new mathematical concepts and techniques. His best known contribution to mathematical physics is the reformulation of Newtonian mechanics, now called Hamiltonian mechanics. This work has proven central to the modern study of classical field theories such as electromagnetism, and to the development of quantum mechanics. In pure mathematics, he is best known as the inventor of quaternions.Hamilton is said to have shown immense talent at a very early age. Astronomer Bishop Dr. John Brinkley remarked of the 18-year-old Hamilton, 'This young man, I do not say will be, but is, the first mathematician of his age.'
