HeвЂ™d walked to the college in heavy rain a fortnight earlier, and the wet sheet treatment allegedly meted out by his wife, a big fan of homeopathy, probably didnвЂ™t help. Sadly, in late 1864, George Boole was struck down by pnuemonia at the age of 49. Together, they had five daughters, one of whom ( Alicia) went on to achieve fundamental results in 4-dimensional geometry.Д«ooleвЂ™s landmark book The Laws of Thought appeared in 1854, laying out rules of logic and their application to probability, and was followed by books on differential equations and the calculus of finite differences. She provided valuable input into the three books he wrote in Ireland. In 1855, he married Mary Everest, more than fifteen years his junior, another self-taught English mathematician who saw herself as a mathematical psychologist. It was a remarkable achievement for a man with no university education.Д«oole was a frugal man with sympathies for societyвЂ™s less privileged classes, and in his early years in Cork-in the deep south of a country still reeling from the effects of the Great Famine-his letters reveal that his social conscience was bothered by the opulence enjoyed in some circles. His correspondence with mathematicians Arthur Cayley and Augustus de Morgan, and the support they offered him, enabled Boole to secure the first professor of mathematics position at the brand new QueenвЂ™s College Cork, in Ireland. He started conducting original research, and is credited with creating invariant theory in the early 1840s. Over the next decade, he continued teaching, reading widely and learning advanced mathematics by himself. His self-taught mastery of continental languages as well as his proficiency in Latin and Greek gave him a distinct edge over his better educated mathematics contemporaries, as he was able to read European texts which others in England tended to ignore. He also wrote, and translated, poetry, and was very concerned about the moral upbringing of his pupils. At age 16, he began teaching to support his family, and before his 19th birthday heвЂ™d opened his own school in Lincoln. Born to a shoemaker father, he had little formal education, but was a gifted student with an obsession for learning and self-improvement. George Boole-like Newton before him-was an unlikely success story. By late 1948, Shannon had introduced what we now know as information theory, and digital computers soon followed. Both Victor Shestakov at Moscow State University in 1935 and Claude Shannon at MIT in 1937 proposed using Boolean logic to design electrical switches, the latterвЂ™s work paving the way for a major shift in electrical engineering in the USA. However, it wasnвЂ™t until almost a century after BooleвЂ™s pioneering work that the world caught up.

Indeed anyone who even casually searches the Internet, say for вЂњMichael JacksonвЂќ the late beer and whiskey expert rather than the singer and dancer of the same name, knows how to make judicious use of AND, OR and NOT. вЂњ He adds that while it would be another decade before Boole refined his ideas and published his first work on symbolic logic, вЂњBoole referred to the incident many times in later life and seems to have regarded himself as cast in an almost messianic role.вЂќД«oolean algebra and Boolean logic are very well known today, and form the backbone of electrical engineering and computer science. MacHale writes that this was when вЂњBoole first contemplated the ideas which were to grow into his major contribution to mathematics-the expression of logical relations in symbolic or algebraic form. So reports mathematician Des MacHale in his biography The Life and Work of George Boole: A Prelude to the Digital Age ( Cork University Press, 2014).

The thought however smouldered in his subconscious and became an integral part of his main ambition is life-to explain the logic of human thought. вЂњHe relates that the thought flashed upon him suddenly, but he laid it aside for many years. BooleвЂ™s came early in 1833, when he was only 17, while walking across a field in Doncaster: NewtonвЂ™s Eureka, or Aha!В Moment, was his celebrated musing on falling apples, in 1666 when he was 23, which in due course inspired his development of the theory of gravitation. Both men were from Lincolnshire, England, and had Unitarian leanings, which impacted their career paths in the Anglican dominated world of their eras.ДЇurthermore, both made key mental breakthroughs while enjoying fresh air outdoors. Isaac Newton, Wikipedia tells us, вЂњis widely recognised as one of the most influential scientists of all time and as a key figure in the scientific revolution.вЂќ George Boole (1815-1864) was undoubtedly also one of the most influential scientists of all time, and a key figure in the digital revolution.
