Hamilton&#8217;s famous creation of a strange new number system, called Quaternions, on the banks of the Royal Canal in Dublin on October 16, 1843. Hamilton was walking with his wife Helen from their home at Dunsink to a meeting of the Royal Irish Academy (at that time) in Grafton Street.<\/p>\n<p>The walk retraces Hamilton&#8217;s steps from Dunsink Observatory to Broom Bridge in Cabra where he had his Eureka moment. He had ben for many years trying to create an algebra of three dimensional space, but had been unable to do so. His Eureka moment was to see that he could do this, but in four dimensions represented by quaternions. Hamilton performed a piece of mathematical graffiti by scratching his quaternion formulas on a stone in the canal bridge.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-7 fusion_builder_column_1_2 1_2 fusion-flex-column\" style=\"--awb-bg-size:cover;--awb-width-large:50%;--awb-margin-top-large:0px;--awb-spacing-right-large:3.84%;--awb-margin-bottom-large:20px;--awb-spacing-left-large:3.84%;--awb-width-medium:100%;--awb-order-medium:0;--awb-spacing-right-medium:1.92%;--awb-spacing-left-medium:1.92%;--awb-width-small:100%;--awb-order-small:0;--awb-spacing-right-small:1.92%;--awb-spacing-left-small:1.92%;\"><div class=\"fusion-column-wrapper fusion-column-has-shadow fusion-flex-justify-content-flex-start fusion-content-layout-column\"><div class=\"fusion-text fusion-text-4\"><p>Quaternions now play a fundamental role in computer games and animation, special effects in movies, space navigation, physics, engineering and many other areas. The walk was established by Prof Tony O&#8217;Farrell of Maynooth University in 1990 and is continued by Dr Fiacre O&#8217;Cairbre also of MU.<\/p>\n<p>In an act of mathematical vandalism, Hamilton opened up a whole new mathematical landscape where mathematicians could now feel free to conceive new algebraic number systems that were not shackled by the rules of ordinary numbers in arithmetic. According to Dr O&#8217;Cairbre Hamilton freed algebra from arithmetic and was called the Liberator of Algebra.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":3,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_vp_format_video_url":"","_vp_image_focal_point":[],"footnotes":""},"class_list":["post-8466","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Hamilton Walk &#8211; MATHS WEEK IRELAND<\/title>\n<meta name=\"description\" content=\"Maths Week will take place from 11 - 19 Oct. 2025.
