Karel Čapek wrote with intelligence and humor on a wide variety of subjects. .... He is perhaps best known as a science fiction author, who wrote long before science fiction became established as a separate genre. He can be counted as one of the founders of classical non-hardcore European science fiction, which focuses on possible future (or alternative) social and human evolution on Earth, rather than technically advanced stories of space travel.

The paper containing the culmination of the calculus of operation, and the theoretical as well as technical origin of Boole’s revolution in mathematical logic, treated systematically in 1847. Boole’s innovative combination of logical propositions by means of algebraic symbols rested entirely on his early development of calculus of operations, which he conducted following Herschel’s and Babbage’s early work, also pursued independently by Gregory and De Morgan. Boole’s primary aim was the ‘distillation’ of algebraic calculi common to different areas, like propositions, classes and probabilities. The General Method of Analysis was awarded the Mathematical Medal of the Royal Society in 1844. Philosophical Transactions of the Royal Society of London, vol. 134, part II.
