George Boole (1815 ? 1864) was a largely self-taught English mathematician, philosopher, and logician, most of whose short career was spent as the first professor of mathematics at Queen's College, Cork in Ireland. He worked in the fields of differential equations and algebraic logic and Boolean algebra. Boolean logic is credited with laying the foundations for the information age. Through his work on algebraic logic he laid some of the mathematical foundations of modern computing. - In the first paper, Boole illustrates the "doctrine of discontinuity", and deduces the succession of three theorems, the last of which is identical with that of Fourier's, though in a new form. -- The second paper demonstrates the evaluation of multiple definite integrals by using discontinuous functions. Humphrey Lloyd FRS FRSE MRIA (1800?1881) was an Irish physicist. He was Erasmus Smith's Professor of Natural and Experimental Philosophy at Trinity College Dublin (1831-1843) and much later Provost (1867?1881). Lloyd is known for experimentally verifying conical refraction, a theoretical prediction made by William Rowan Hamilton about the way light is bent when traveling through a biaxial crystal. James McCullagh was born in County Tyrone, Ireland. He was a fellow of Trinity College Dublin and a contemporary there of William Rowan Hamilton. In 1835 he was appointed Erasmus Smith's Professor of Mathematics at Trinity College Dublin and in 1843 became Erasmus Smith's Professor of Natural and Experimental Philosophy. In this his most important paper on optics, he begins by defining what was then a new concept, the curl of a vector field. He first showed that the curl is a covariant vector in the sense that its components are transformed in the appropriate manner under coordinate rotation. he set out to develop a potential function for a dynamical theory for the transmission of light. MacCullagh found that a conventional potential function proportional to the squared norm of the displacement field was incompatible with known properties of light waves. Robert Mallet's paper is considered one of the foundations of modern seismology. He is also credited with coining the word "seismology" & other related words. He built the Fastnet Lighthouse.
