About Sir William Rowan Hamilton

William Rowan Hamilton

Hamilton became professor of astronomy at TCD and royal astronomer of Ireland. Hamilton was a prodigy and knew 13 languages by the age of 9. He introduced the terms ‘scalar’ and ‘vector’ into mathematics, and he invented the method of quanternions as a new algebraic approach to 3D geometry. This turned out to be the seed of much modern algebra

Today there is a Crater Hamilton on the moon, in memory of this great mathematician.

  4. William Rowan Hamilton (Mathematician and Astronomer) Hamilton had a fascinating personality. He was described by friends as having "a buoyant cheerfulness and a kindly human-heartedness" and was legendary for his great courtesy and amiability. Women invariably found him charming and apparently attractive because of his obvious intelligence.

Sir William Rowan Hamilton PRIA FRSE (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.' Source:
