Irish inventions and discoveries are objects, processes or techniques which owe their existence either partially or entirely to an Irish person. Often, things which are discovered for the first time, are also called "inventions", and in many cases, there is no clear line between the two. Below is a list of such inventions.
Sir William Rowan Hamilton was an Irish mathematician, astronomer, and physicist. He was Andrews Professor of Astronomy at Trinity College Dublin.
The following is a timeline of low-temperature technology and cryogenic technology. It also lists important milestones in thermometry, thermodynamics, statistical physics and calorimetry, that were crucial in development of low temperature systems.

George Francis FitzGerald was an Irish physicist known for the Lorentz–FitzGerald contraction, which became an integral part of Albert Einstein's special theory of relativity.
George Johnstone Stoney was an Irish physicist. He is most famous for introducing the term electron as the "fundamental unit quantity of electricity".
Loughrea is a town in County Galway, Ireland. The town lies to the north of a range of wooded hills, the Slieve Aughty Mountains, and Lough Rea, the lake from which it takes its name. The town's cathedral, St Brendan's, dominates the urban skyline.
Louis Brennan was an Irish mechanical engineer and inventor.
Thomas Preston was an Irish scientist whose research was concerned with heat, magnetism, and spectroscopy. He established empirical rules for the analysis of spectral lines, which remain associated with his name. In 1897 he discovered the Anomalous Zeeman Effect, a phenomenon noted when the spectral lines of elements were studied in the presence or absence of a magnetic field. Preston reported, in an important paper published in The Scientific Transactions of The Royal Dublin Society, read on 22 December 1897, and published the following April, that he reported results more complicated than Zeeman had reported. Following this up further, he reported in a second paper in the RDS Scientific Transactions, read on 18 January 1899, and published the following June, that he had found results that were ’very startling’ and appeared ‘quite contrary to all theoretical explanations’. The full explanation had to wait for the theory of relativity and the introduction of quantum mechanics, which were to shake the rigid framework of Newtonian conceptions of absolute time and space. Preston’s results were an important step in this development.
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process. Multiple discovery sometimes occurs when multiple research groups discover the same phenomenon at about the same time, and scientific priority is often disputed. The listings below include some of the most significant people and ideas by date of publication or experiment.
Ireland's Greatest was a 2010 public poll by Raidió Teilifís Éireann (RTÉ) and associated television documentary series broadcast on RTÉ One, where viewers voted to choose the greatest person in the history of Ireland. The concept was based on the BBC series 100 Greatest Britons. The winner was John Hume.
The 19th century in science saw the birth of science as a profession; the term scientist was coined in 1833 by William Whewell, which soon replaced the older term of (natural) philosopher.
