Many of our computer databases utilize boolean logic as the basis of querying the database. Boolean logic has a much older history than most computer users imagine. It is helpful to understand the background and theory behind this concept, because this theory is the foundation on which contemporary computer science and information technology

has been built.

George Boole was an English mathematician. Born in 1815, he had no formal higher education, but had a natural gift for mathematics. He studied Newton and other mathematicians from the eighteenth and nineteenth centuries. He began submitting papers to mathematical journals and by 1844 was awarded a medal for discussing ways in which algebra and calculus could be combined and applied to several other disciplines. In 1847, Boole wrote a paper entitled "Mathematical Analysis of Logic" (Smith, 1993). His premise in this paper was the relationship of logic and mathematics; he thought logic was more properly associated with mathematics rather than philosophy.

Boole received a professorship in mathematics at Queens College in Ireland, based on his writings. In his most famous work, "An Investigation into Laws of Thought, on Which Are Founded the Mathematical Theories of Logic and Probabilities," (Smith, 1993), published in 1854, Boole wanted to separate logic from philosophy and combine it with algebra as a science unto itself (Smith, 1993).

Boole was able to analyze the mechanics of human reasoning and the result of this analysis became the principle of information retrieval, from manual and mechanical, to electronic. Boole believed that reasoning involved either the addition of different concepts to form more complex concepts or the separation of complex co...

- The work of George Boole on mathematical logic that gave birth to the “Boolean Algebra” was the most important contribution to the development of computer technology. We are going to see briefly, how the prodigy George Boole came from an economically modest family, to change the way we relate with logic, influencing the concept of computing and processing information. We are also going to analyse how his work in algebra revolutionised the way we think and symbolise logic sets, making the binary code and logic relations as the fundamental tool in the evolution of computer systems and networks, from the first breakthrough of Boole's work, until many years later, when science identified that hi...

## DatabaseManagement System and IRR Essay

- A database management system (DBMS) is a collection of programs that's enable you to store, modify, and extract information from a database (Smitha, 2006). DBMSs have many different types that are run on a personal computer as a small system to large systems that are run on mainframes. An example of database function is like flight reservation system, hotel computerized system and clinic system. DBMS also is a computer program created to manage the database and implement operations on the data requested by the comprehensive consumer.... [tags: data, Boolean IR, search system]

## Essay on Heidegger and the Logic of Categorical Syllogisms

- Heidegger and the Logic of Categorical Syllogisms According to traditional syllogistic logic, which has its roots in Aristotle, there are four types of propositions: the A proposition ("All S are P"), the E proposition ("No S are P"), the I proposition ("Some S are P"), and the O proposition ("Some S are not P"). These propositional types represent all of the possible combinations of the dichotomies of affirmative/negative and universal/particular. Each makes a claim that a certain essent (the particular I and O propositions) or an entire class of essents (the universal A and E propositions), the subject or subject-class, relates in some way (belongs or does not belong) to a class o...

## Fuzzy Logic Essay

- Fuzzy Logic "So far as the laws of mathematics refer to reality, they are not certain. And so far as they are certain, they do not refer to reality." -Albert Einstein, Geometry and Experience “It’s funny how when we’re the recipients of pain we’re clear that it’s black and white. But when we’ve got something to gain there are shades of gray.” – Dr. Laura Schlessinger Fuzz adds extreme choices of black and white, between shades of gray. Claim ness is given with fuzz; it does not make us choose.... [tags: Essays Papers]

## Fuzzy Logic Essay

- Fuzzy Logic Fuzzy Logic is a term used to identify a new trend of quantifying partial truths. One disadvantage of most rule sets that they cannot process inconsistent data. Fuzzy logic is a superset of conventional logic that has been extended to handle the concept of partial truth, being values that lie between "completely true" and "completely untrue". Dr. Lotfi Zadeth of UC/Berkley first introduced it in the 1960s as a means of modeling the uncertainty of natural language. All this works by using expanding on Boolean logic and the concept of subsets.... [tags: Papers]

## George Boole's Impact on Mathematics Essay

- “He had a better mind and a more rigorous temperament than me; he thought logically, and then acted on the conclusion of logical thought. Whereas most of us, I suspect, do the opposite: we make an instinctive decision, then build up an infrastructure of reasoning to justify it. And call the result common sense.” This quote, by Julian Barnes, embodies the reason George Boole was my choice for my mathematician. I have always been fascinated by logic and reasoning, possibly because I constantly find myself in arguments which I prefer to call friendly debates.... [tags: logic, award, computers]

## A Brief Look at Malware Types Essay

- Malware Types Logic Bomb: A logic bomb is code which consists of two parts: 1- A pay load, which is an action to perform. The payload can be anything, but has the connotation of having a malicious effect. 2- A trigger, a boolean condition that is evaluated and controls when the payload is executed. The exact trigger condition is limited only by the imagination, and could be based on local conditions like the date, the user logged in, or the operating system version. Triggers could also be designed to be set off remotely, or - like the "dead man's switch" on a train - be set off by the absence of an event.... [tags: logic bomb, back door, virus]

## Logic And The Concept Of Logic Essay

- The concept of logic is defined by the Webster Dictionary as “a proper or reasonable way of thinking about or understanding something”. The concept of logic is a way of thinking, solving, reasoning, and almost a state of mind given the right circumstances. Logic is a broad statement because it could mean an abundance or lack of logical thinking, or use of. Logical thinking is what prevents people from making poor decisions, and sometimes a lack of thinking creates unwanted effects. Logic is normally used in sentences as logically, logical, logicality and sometimes can also be called logistics.... [tags: Reasoning, Logic, Thought, Scientific method]

Thinking is a very important process of how our thoughts, when transferred verbally or written on paper, can produce a clearer understanding of our views. The nature of logic as it relates to critical thinking, and my perceptual process have been influenced through sources of enculturation.

## Nature of Logic Essay

- Nature of Logic The nature of logic and critical thinking go hand in hand. A person must use logic during the critical thinking process. However, each person’s logic may depend on his/her perceptual process or their perceptual barriers. No person can ever fully understand their own perceptual process in its entirety. The reason being is that no person knows all of their perceptual barriers. Without knowing all of the barriers, how is a person able to determine the process in which they perceive things....
