How Boolean Logic Works" Binary - So Simple a Computer Can Do It. Binary - So Simple a Computer Can Do It While every modern computer exchanges and processes information in the ones and zeros of binary, rather than the more cumbersome ten-digit decimal system, the idea isn't a new one. Australia's aboriginal peoples counted by two, and many tribes of the African bush sent complex messages using drum signals at high and low pitches.
Morse code, as well, uses two digits (dots and dashes) to represent the alphabet. Gottfried Leibniz laid the modern foundation of the movement from decimal to binary as far back as 1666, while John Atanasoff, a physics professor at Iowa State College, had built a prototype binary computer by 1939. In the meantime, Claude Shannon, Konrad Zuse and George Stibitz had been pondering away in their own corners of the world, musing on the benefits of combining binary numbers with boolean logic. Basically, binary simplifies information processing. Especially utilisation. So, how does it work? It's not so very difficult, really. Simple. Claude Shannon (1916 - 2001) Claude Shannon (1916 - 2001) In 1936, graduate student Claude Shannon arrived at the Massachusetts Institute of Technology.
In the best tradition of grad students, Shannon was short of money, and happy to be recruited by his professor, Vannevar Bush, to tend Bush's unwieldy mechanical computing device - the Differential Analyser. The Differential Analyser, while a marvel of scientific engineering for its time, was a lot of hard work to maintain. Basically an assembly of shafts and gears, the gears themselves had to be manually configured to specific ratios before any problem could be ‘fed’ to the machine - a boring, laborious (and extremely messy) business: "I had to kind of, you know, fix [it] from time to time to keep it going". Encouraged by Bush to base his master's thesis on the logical operation of the Differential Analyser, Shannon inevitably considered ways of improving it, perhaps by using electrical circuits instead of the present cumbersome collection of mechanical parts.
Hermeneutic circle. The hermeneutic circle (German: hermeneutischer Zirkel) describes the process of understanding a text hermeneutically. It refers to the idea that one's understanding of the text as a whole is established by reference to the individual parts and one's understanding of each individual part by reference to the whole. Neither the whole text nor any individual part can be understood without reference to one another, and hence, it is a circle. However, this circular character of interpretation does not make it impossible to interpret a text; rather, it stresses that the meaning of a text must be found within its cultural, historical, and literary context. History[edit] With Friedrich Schleiermacher, hermeneutics begins to stress the importance of the interpreter in the process of interpretation.
Another instance of Heidegger's use of the hermeneutic circle occurs in his examination of The Origin of the Work of Art (1935–1936). Critique[edit] Judith N.

George Boole (1815 - 1864) George Boole (1815 - 1864) The original Working Class Boy Made Good, Boole was born in the wrong time, in the wrong place, and definitely in the wrong class - he didn't have a hope of growing up to be a mathematical genius, but he did it anyway.
Born in the English industrial town of Lincoln, Boole was lucky enough to have a father who passed along his own love of math. Young George took to learning like a politician to a pay rise and, by the age of eight, had outgrown his father's self-taught limits. A family friend stepped in to teach the boy basic Latin, and was exhausted within a few years. Boole was translating Latin poetry by the age of twelve. By the time he hit puberty, the adolescent George was fluent in German, Italian and French.
It was time to move on. At the age of 24, George Boole published his first paper ('Researches on the Theory of Analytical Transformations') in the Cambridge Mathematical Journal. Rockwell Schrock's Boolean Machine. Boolean Searching on the Internet.
