Its Common Sense That Animals Do Suffer essays

Its Common Sense That Animals Do Suffer essays It's Common Sense That Animals Do Suffer Many people and animal right activists object to having animals used in experiments. The animals used in medical research are put through experiment to help find cures for the well being of mankind, but somewhere down the line, some of these animals are tormented and tortured. Most of the researchers or "animal abusers" are caught and brought to court because of the heinous acts committed against these creatures and the excuse most animal abusers use is that animals do not suffer because they cannot communicate or express feelings. The author of "Animal Liberation", Peter Singer, argues that animals do suffer and most animals can communicate and express their feelings, such as pain. He states this clearly when he says, "Most people agree unhesitatingly that animals like cats and dogs can and do suffer." Many animals, such as mammals and birds communicate pain through, whimpering, yelping, and whining. Also, if animals did not suffer, then why would there be a law that prohibits cruelty towards animals. This law fines and even incarcerates people who abuse animals. Moreover, this law infers that animals do suffer and also, that they do have rights against inflicted, and unnecessary pain. In addition, one reason why people experiment with animals and do not care if the are hurting them is because animals do not have a language and cannot voice their feelings so they say. Science research found that chimpanzees ( a species similar to humans) can communicate and have a developed language. But what about infants? Infants cannot talk. So, are the not able to suffer because they lack a language? Why are these medical experiments not performed on infants? If animals do not hurt because they cannot communicate, then why can we not say the same for human babies? All in all, medical researchers are using animals to come up with cure for the many diseases and viruses humans bear....

Definition of Algorithm in Mathematics

Definition of Algorithm in Mathematics An algorithm in mathematics is a procedure, a description of a set of steps that can be used to solve a mathematical computation: but they are much more common than that today. Algorithms are used in many branches of science (and everyday life for that matter), but perhaps the most common example is that step-by-step procedure used in long division. The process of resolving a problem in such as what is 73 divided by 3 could be described by the following algorithm: How many times does 3 go into 7?The answer is 2How many are left over? 1Put the 1(ten) in front of the 3.How many times does 3 go into 13?The answer is 4 with a remainder of one.And of course, the answer is 24 with a remainder of 1. The step by step procedure described above is called a long division algorithm. Why Algorithms? While the description above might sound a bit detailed and fussy, algorithms are all about finding efficient ways to do the math. As the anonymous mathematician says, Mathematicians are lazy so they are always looking for shortcuts. Algorithms are for finding those shortcuts. A baseline algorithm for multiplication, for example, might be simply adding the same number over and over again. So, 3,546 times 5 could be described in four steps: How much is 3546 plus 3546? 7092How much is 7092 plus 3546? 10638How much is 10638 plus 3546? 14184How much is 14184 plus 3546? 17730 Five times 3,546 is 17,730. But 3,546 multiplied by 654 would take 653 steps. Who wants to keep adding a number over and over again? There are a set of multiplication algorithms for that; the one you choose would depend on how large your number is. An algorithm is usually the most efficient (not always) way to do the math. Common Algebraic Examples FOIL (First, Outside, Inside, Last) is an algorithm used in algebra that is used in multiplying polynomials: the student remembers to solve a polynomial expression in the correct order: To resolve (4x 6)(x 2), the FOIL algorithm would be: Multiply the first terms in the parenthesis (4x times x 4x2)Multiply the two terms on the outside (4x times 2 8x)Multiply the inside terms (6 times x 6x)Multiply the last terms (6 times 2 12)Add all the results together to get 4x2 14x 12) BEDMAS (Brackets, Exponents, Division, Multiplication, Addition and Subtraction.) is another useful set of steps and is also considered a formula. The BEDMAS method refers to a way to order a set of mathematical operations. Teaching Algorithms Algorithms have an important place in any mathematics curriculum. Age-old strategies involve rote memorization of ancient algorithms; but modern teachers have also begun to develop curriculum over the years to effectively teach the idea of algorithms, that there are multiple ways of resolving complex issues by breaking them into a set of procedural steps. Allowing a child to creatively invent ways of resolving problems is known as developing algorithmic thinking. When teachers watch students do their math, a great question to pose to them is Can you think of a shorter way to do that? Allowing children to create their own methods to resolve issues stretches their thinking and analytical skills. Outside of Math Learning how to operationalize procedures to make them more efficient is an important skill in many fields of endeavor. Computer science continually improves upon arithmetic and algebraic equations to make computers run more efficiently; but so do chefs, who continually improve their processes to make the best recipe for making a lentil soup or a pecan pie. Other examples include online dating, where the user fills out a form about his or her preferences and characteristics, and an algorithm uses those choices to pick a perfect potential mate. Computer video games use algorithms to tell a story: the user makes a decision, and the computer bases the next steps on that decision. GPS systems use algorithms to balance readings from several satellites to identify your exact location and the best route for your SUV. Google uses an algorithm based on your searches to push appropriate advertising in your direction. Some writers today are even calling the 21st century the Age of Algorithms. They are today a way to cope with the massive amounts of data we are generating daily. Sources and Further Reading Curcio, Frances R., and Sydney L. Schwartz.
