Boolean Logic 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
thromboembolism or anticoagulation” and “prophylaxis” to determine the results. This yielded 3401 results, however it was discovered that by using “or” as a Boolean operator rather than “and” lead the discovery of articles which were not appropriately related. The articles did not have all the criteria required to answer the proposed PICO question. Therefore, the Boolean operators were changed to meet the criteria of the question. This included using the keywords “venous thrombosis” and “anticoagulation” and “prophylaxis”
inputs. Using the truth table will help designers to write Boolean expressions more easily. An example of the truth table can be found at Figure 2.3. The output V will be one if two or three of the inputs are one. 2.2 Gates [2] A gate is a primitive building box which describes Boolean expressions. Standard logic gates are gates for the logic operators AND, OR and NOT (Figure 2.2). These gates are formed from transistor switches. Every Boolean expression can be implemented by wiring a combination of
signals from point A to point B. The information is transmitted from one circuit to another by using electronic currents. However, the logic sequences that have been incorporated into the electrical circuit is what distinguishes digital electronics from the electronic devices from the past. Binary logic, also known as Boolean theory, implements a base two-value logic system of “true” and “false” to transport information through electric signals. The electronic gate (circuit) is the source of what
off. At one point even Albert Einstein used Boole’s methods of mathematics to continue to advance of his own mathematics and sciences. Lastly, to wrap up, after living for a short 49 years, Boole is buried in the Church of Ireland. Boolean algebra and Boolean Logic are still around to this day and probably will be for many, many more years.
The Structure of Wholeness Using a part-whole-calculus the vague concept of wholeness is rendered precisely as the structure of an atomic boolean lattice. The so-defined prototypical structure of wholeness has the status of a category, since every element of our experience may be considered as an intended application of it. This will be illustrated using examples from different ontological spheres. The hypothetical and therefore fallible character of the structure is shown in its inadequacy in
British mathematician, and he is known as the inventor of Boolean Algebra. His theories combined the concepts of logic and mathematics, and hence he is known as the father of mathematical logic. This combination of mathematics and logic came to be known as Boolean algebra, and is the basis of digital electronic design, which is used in fields ranging from telephone switching to computer engineering. Because of the utilization of the concepts of Boolean algebra in electronics and computers, George Boole
One important branch of philosophy is logic. Through logic, the world can see how questions are developed, why questions are asked, and how questions are invalid. Many logicians have been formulating hypothesis centering around logic for years. Aristotle and George Boole are two logicians who are extremely well known for their work in the philosophical field and their conflicting viewpoints when considering logic. In the textbook, A Concise Introduction to Logic by Patrick J. Hurley, tenth edition
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. The first thing I did to determine my mathematician was turn to Amazon to find a good short book that I might find interesting from any of the options. After stumbling upon "The Mathematical Analysis of Logic: Being an essay towards a calculus of deductive reasoning" I realized I had found my Mathematician
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
the timing of the turns could be controlled by the bit output of the counter. We used binary logic to choose the different bits the robot would turn at while making sure that only one combination would make the turn. NAND, OR and NOT gates were used in order to make the turn selection. We were careful to set the frequency low as we did not want the robot to make each turn multiple times. After the binary logic was implementing, analog circuitry was in place in order to feed a signal to the motor control
My guiding principle has been my passion to keep learning about and using Computers and Mathematics. Having a profound interest in discrete mathematics, I have always wanted to work on logic and that is the major reason for me to choose Computing. During my A-levels, I learned Visual Basic independently and how logic can be utilized for problem solving in any complex scenario. I also implemented these useful VB codes into my AS ICT coursework for which I received 97%. The puzzle-solving aspect of mathematics
In Huemer’s The Problem Of Political Authority an argument is made against the idea of political authority. Political authority is defined as the feature that the government has that makes it morally permissible for them to do things that ordinary citizens cannot. The idea in this argument is that the government should not have rights that citizens do not have. The purpose of this paper is to show that Huemer’s argument fails by arguing a consent-based response to Huemer’s criticisms, which shows
Critical thinking takes consistent behavior in asking the right questions about the subject. In my life, I have come across people who ask many questions and some people who “go with the flow” and believe everything they hear because it is spoken with some sort of authority. Assumptions can be damaging to relationships and without critical thinking and communication, our thought process can assume the wrong idea entirely. When I speak with someone who is a critical thinker, they can be so convincing
Bertrand Russell, a renowned analytic philosopher, argues about the existence of God in his article “Is there a God?” (1952). For most of his life Russell held the opinion that religions are meant to instill distress and helplessness into people’s minds and belief in religion is the major cause for all the deadly conflicts that have occurred in the past. In his article “Is there a God?” Russell discusses how theologians have been presenting their arguments to prove God’s existence and then gives
In this paper I will present two differing views on the topic of the design argument. In particular, I will explain William Paley's view supporting the design argument and Bertrand Russell's view against the design argument. After a presentation of the differing views, I will then evaluate the arguments to show that William Paley has a stronger argument. There are several forms of the design argument. The general form of the design argument starts with the basic idea that certain parts of the universe
The Cove is a film of activism, a film meant to move the hearts of individuals who love and support the rights of mammalian sea-dwellers like that of whales, porpoises, and most importantly dolphins. Produced in 2009 by the Oceanic Preservation Society it offers a unique perspective, when compared with other activist documentaries. In The Cove the producer and co-founder of the Oceanic Preservation Society was actually personally involved in the filming efforts and worked directly with dolphin trainer
Donald Davidson identifies three forms of knowledge which he believes to be irreducible and interdependent: knowledge of self, which is immediately known; knowledge of the outside world, which is simply caused by the events and objects around you, and thus depends on sense organs to be semi-immediately known, yet open to uncertainty; and knowledge of the minds of others, which is never immediately known. The standard approach to philosophy tries to reduce one of these forms of knowledge to one or
In Meditations on First Philosophy, Descartes illustrates that the objective reality of some of his ideas seems so great that he cannot be the cause of such ideas, thus something else also exists in the world (29). Though Descartes inquires particularly into adventitious ideas to support his claim, he does not offer the definitions of innate and adventitious ideas clearly, nor does he explain the differences of them in any detail. In this paper, I will demonstrate that the ambiguity of innate and
Russell Brand has a newfound fame—not in Hollywood but in the political realm. Brand speaks very elegantly toward social issues, especially to an American ear. Taking command of any interview, he speaks quickly and clearly. However, as with most postmodern thinkers, his points and arguments seem to lack depth or critical consideration of the points made. In this article, Russell Brand comments on the recent events he was involved in at the GQ awards. His comments, entitled “Russell Brand and the
