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
and life lessons. In today's modern world, we pursue knowledge because it is useful for obtaining information. For many years, humans have strived to gain advanced levels of knowledge and information. In my opinion, a disagreement is the opposite of logic; it contradicts or opposes evidence that has otherwise been proven true. Disagreements act as obstacles that hinder the pursuit of knowledge. The idea of disagreement can be connected to the two important ways of knowing: perception and reasoning.
The human perception of the world is formed through a lense, or perhaps more accurately a filter; the information that is acquired from what surrounds us is articulated through abstract concepts as opposed to physical; that is to say that the basis of our understanding of the world is fundamentally abstract. This is true of the essence of thought and understanding, ergo it must be true of each product of these two processes: truth qualifies as one of these products. However, truth, literally defined
their implicit concept of truth. Even if the skeptic avoids an absolute judgment, the fact that we make judgments about better or worse still presupposes the first principle (even if the principle of non-contradiction is indemonstrable), and the same logic is given to proposition: for we deem some propositions to be closer to the truth than others. Therefore, it is not possible to consistently both affirm and deny the same proposition. Altogether, any judgment presupposes that something is nearer to
“Fat Acceptance”: An Argument Lacking Validity Cynara Geisslers’ essay “Fat Acceptance: A Basic Primer,” was published in Geez Magazine in 2010. The focus of the essay is to refute the pressure of society to be thin and promote self-acceptance regardless of size. While this essay touches on many agreeable points, it tends to blow many ideas out of context in an attempt to create a stronger argument. The article takes on a one-sided argument without any appropriate acknowledgement of the opposition
There is so much evil in the world such as: murder, child mortality, torture, rape, assault and more. So how can there be an all loving God if these things are constantly happening? In this paper, I will be arguing that there is in fact no such thing as an all loving and all powerful God due to Evil. When I think of an all-loving God, I think of God as someone who would never allow a child to be kidnapped, raped, tortured and killed. I think of God as someone who would not allow anything bad
“How can you identify a single counterfeit penny, slightly lighter than the rest, from a group of nine, in only two weighs?”(Suri, 4) This is an interesting mathematical puzzle which everyone might had played in our childhood. The puzzle was invented by a legendary mathematician Martin Gardner in 1956. Are you wondering that why great mathematicians such as Martin Gardner were still interesting in this kind of recreational math? An editorial written by Manil Suri who is an Indian mathematician expounded
Do people even have face-to-face conversations any more? In the article, “The Flight From Conversation,” by Sherry Turkle is successful on backing up that we, as people should get off the phone and social media so we can learn how to actually hold a proper conversation with someone else. Turkle supports her argument by using rhetorical strategies like logos, kairos, and ethos. To begin with, through logos Turkle gives logical reasoning that helps her central claim succeed, but also fail. She uses
In the article “Bring Back Flogging” Jeff Jacoby writes that prison inmates are given a disservice more than people who used to be flogged in the 1600s. Flogging was a punishment that used for a wide variety of crimes and was usually done publicly with the victim being whipped an appointed number of times. Jacoby writes that flogging is a more educational experience than going to jail because it is an experience that the criminal will never forget. He goes on to say that another reason why prisons
