Four Eras of Writing Essay Example for Free

Four Eras of Writing Essay History has evolved over the last two centuries. In the introduction to Interpretations of American History edited by Francis G. Couvares, et al., he states that the transition of the way history was interpreted has only â€Å"linked the past more strongly to the present† (Couvares 1). Before, historians –mostly white male- used to report only about â€Å"male† topics but since then, different issues have transformed the way history used to be. Over the last 400 years, the four different stages that have reshaped the writing of American history have been the providential, the rationalist, the nationalist, and the professional. Late- nineteenth-century historians, usually called â€Å"historicists† or â€Å"positivists† believed that history was like science and with practice it could be solved. According to Couvares, Croce believed that Positivists were faulty in their assumptions because history was perceived differently every time it was written down since no one thinks exactly alike. With so many different views, historians are usually adding more and more information to each other’s perceptions. Couvares says that â€Å"history is historiography, the study of history and its changing interpretations† (Couvares 3). When interpreting history, historians were influenced by their personal circumstances, beliefs, and environment. During the seventeenth and eighteenth centuries, all through the Civil War, historians wrote a form of â€Å"providential history† (Couvares 4). Puritans – usually ministers, magistrates, and women- wished to â€Å"justify the ways of God to man, and vice-versa† (Couvares 4) in their history. They interpreted what was happening at the time as a sign of God wanting them to move forward which led them to believe that the Revolution was a win for â€Å"reformed† Christianity. With the European Enlightenment, came more of an intellectual and natural way of thinking. Couvares notes how the â€Å"rationalist historians†, greatly influenced by Newton and Locke, prospered along with the people who had been at the top of the colonies before. During this stage, the progress of reason (Couvares 5), as they called it, was their new belief. Most historians during this time were wealthy and with a high position in society, hence the style of their writing. Because of the way they thought of themselves, their history explained how the enlightened world was a success because of men like them. According to Couvares, Jeffersons Notes on the State of Virginia very much sums up the thought of the rationalists where they were the ones who achieved greatness, it wasnt God driven. However, the rationalists were not that far off from the providential its because their story still pointed upward (Couvares 6). As the nineteenth century went on, historians started to see America as the triumph of Anglo-Saxon people over inferior races (Couvares 6). They thought that because America had overcome other inferior races that they were better. Couvares explains how Bancroft organized Americas history around three themes: progress, liberty, and Anglo-Saxon destiny (Couvares 6). This is where the third stage comes in. Their idea that the Teutonic people were supposed to spread freedom across the globe was the start to their sense of pride, love, and nationalism. Not only were men, but also female historians hooked on this idea. Helen Hunt Jackson wrote about white-Indian relations, which at the time was a big obstacle to jump; while at the same time anthropologists beginning to study these relationships. Around the 1870s, though, Bancroft seemed like the past and the future possibilities were just around the corner. As universities started being built and education was more common among the middle class, history was becoming a profession. Practiced by the people who had access to advanced education, white men, they started concerning themselves with specialized training, research methodology, and educational credentials (Couvares 7). Adams and Turner both shared the belief of applying Darwins method to history. Adams argued that history was like physics and that it could be deciphered the same way. Even though Adams couldnt accomplish his goal, Turner did while at the same time seeming connected to the nationalists is sharing a little bit of their beliefs. Throughout the first half of the twentieth century, another type of professionals emerged. These Progressive historians, unlike the Adams, saw history as politics and not as science. They believed that science was needed to produce usable facts, and art to persuade people to act on them (Couvares 9) but it was political action what they wanted to accomplish with it; which could be why Progressives could be classified as reformers. Basically, their point was that the function of history â€Å"was to uncover the economic basis of political ideas†¦and educate the citizenry† (Couvares 9). In the end, with the Great Depression going on and the Second World War, the question that was raised was whether or not if the history had prepared them. Nobody could have foreseen what was going to happen, and eventually history continues to be written everyday and like Couvares pointd out, â€Å"history is an act of interpretation† (Couvares 1).

The Epic of Gilgamesh is Truly an Epic Essay -- Literary Analysis

An epic is an extensive narrative poem celebrating the feats of a legendary or traditional hero. There are several main characteristics that make up an epic as a literary genre. First is that, it contains an epic hero, its hero searches for immortality (but doesn't find it physically, only through fame), it delivers an historical message, it is a long poem that tells a story, and the gods or other supernatural beings are interested and involved. The Epic of Gilgamesh is classified as an epic because it fits all the characteristics of an epic as a literary genre. The first important characteristic of The Epic of Gilgamesh that helps to classify it as an epic is that it includes a hero. Gilgamesh is the story’s epic hero. Characteristics that determine an epic hero in the ancient world include strength, beauty, and high social status (Tigay 42). Gilgamesh fits all these descriptions. His great strength was described as that which could be matched by no other. His beauty was so evident that he could have any woman that he wanted. In fact, he slept with all the women in his city. Gilgamesh was also made 2/3 God and 1/3 human. This fact alone raised him up to a god-like social status. He was the king of Uruk because no one could challenge his strength or beauty. Most epic heroes are also widely known and famous which Gilgamesh, being king, obviously was. Aside from his attributes and status, the traditional epic hero must perform heroic feats (Abusch 620). Again, Gilgamesh fits into this category. First, Gilgamesh leads Enkidu on an adventure that will gain further fame for himself and his friend. This was the plan to take a journey to the sacred Cedar Tree and kill the Guardian of the Cedar Forest, Humbaba. This is... ..., Ltd., 1999. 21-48. Print. "Gilgamesh."

History of the Violin and Bow Essay

Stringed instruments such as the violin and its accompanying variations have been used in music for thousands of years. The first officially recorded use of the violin was during medieval European times. The earliest form of the violin was referred to as a Fiddle and the person playing it was termed as a Fiddler. During the 15th century though, the violins began taking on a new shape and began to carve its own history in music. The evolution of the violin continued into the 16th century when it developed what was to become its final look and shape. It is this artistic representation of a violin that we still recognize and use in our present time. An Italian from Cremona named Andrea Amati, is recognized as the founder of the most famous violin making school. The violin making school is not a structure per se but more of a school of thought and characterization. It was during this time that an explosion in violin making reached as far as Europe even as Cremona remained as the home of the best violin makers in the world. The most famous of these violin making families are the Amati, Guarneri, Antonio Stradivari, Rugerri, and Bergonzi. In the music world, the finest musicians openly acknowledge the Stradivari and Guarneri violins to be the best violins ever made over the past 150 years. The Violin is a member of the string instrument family and is capable of producing a 3 octave sound range when played by skilled musicians. The sound a violin creates depends on a number of factors, the most important of which are the type of wood used to produce the body of the instrument and the type of metal strings used.. It is usually 14 inches in length and uses metal strings tightened to various degrees on tuning pegs, to produce its exceptional sound quality. A typical violin is composed of the following parts: Chin rest, F-hole, strings, tuning pegs, scroll, tailpiece, fine tuners, bridge, belly, fingerboard, neck, and back plate. The sound is produced by the instrumentalists skimming a bow over the metal strings. Violins are usually constructed to withstand the 17 pounds of downward force that is regularly applied to the 4 metal strings. But just like any stringed instrument, the Violin in itself will fail to make sweet music for the listeners if not strummed with a bow. The bow is the instrument by which a Violinist makes his instrument sing. His expertise in the use of the bow produces the violins varying tones and pitches. How a bow is shaped and the different parts that form the bow all work together to form the best bow for violin playing. A bow is most often described as an arc shaped piece of wood that has a flat horsehair piece stretched and tensioned across the wood. The tips of the bow are pointed on one end and rounded on the other. Although the violin enjoyed various incarnations as it gained popularity and was played by chamber and orchestra musicians, the violin bow did not keep up with these changes. This led to a total redesign that resulted in what is known as the modern bow. The modern bow is believed to have first made its appearance in France during the 19th century at the hands of the Tourte family. The Tourte family is considered by the violin historians to be the bow maker equivalent of the Stradivari family in violin making. The modern bow has more tension and resistance and uses Pemarnbuco wood as wood stick. Sometimes, makers will add subtle modifications to the bow in the hopes of producing a more handy and usable bow. Admittedly, not much has changed in the 150 year history of the bow. The violin and bow can be thought of in terms of milk and cookies or coffee with cream. One always enhances the best aspects of the other in order to produce a very significant experience for the person whose auditory and sensory perceptions participate in the resulting enjoyable final product of the merging of the 2 instruments.

Civic Engagement At North Eastern State University

We have identified civic battle as a top degree campus-wide precedence through our strategic planning procedure. Our primary barrier to progressing civic battle is a deficiency of campus-wide substructure to back up and capture civic battle activity happening in curricular and co-curricular scenes. The intent of this white paper is to supply a snap shooting of current activity related to civic battle, place a mensurable long-run aspiration, and offer recommendations for traveling frontward. University Planning Group Strategic Plan The University Planning Group sub-committee focused on Culture of Civic Engagement proposed the undermentioned description and definitions to be adopted by the establishment. Civic Engagement at Northeastern State University is the single committedness to prosecute in a shared duty to take attention of the communities in which we live. This is achieved through the survey, contemplation and action necessary to take personal and societal duty in our single Fieldss of involvement every bit good as in the communities in which we live and serve. Civic battle is lending to a larger community ; is caring about the remainder of the universe ; is consciousness of societal, political, and economic issues within the U.S. and globally ; is recommending for a cause ; is active in lending to community. Types of Civic Engagement[ 1 ]: Academic Service Learning – engages pupils in a three-part procedure: schoolroom readying through account and analysis of theories and thoughts ; service activity that emerges from and informs classroom context ; and structured contemplation binding service experience back to specific learning ends.[ 2 ] Volunteerism – committedness and actions to help in a plan or activity that benefits others Community Service – committedness to turn to and function community demands Community Building – physique swearing relationships among persons and groups around issues of common concern Public Education – draw attending to and consciousness of local, national and planetary issues Community Development – identify and increase the human or economic assets of a community Voting and Political Participation – mobilize influence on public policy through formal political channels Civic Leadership – participate in collaborative decision-making for the benefit of the community Public Scholarship – engage in research that serves the public involvement and has community or social benefits Grassroots Alliances – mobilize Alliess with a common involvement to organize schemes for alteration Environment Scan In 2009, NSU participated in two national surveies focused on pupil perceptual experiences and experiences related to civic battle. The National Survey of Student Engagement ( NSSE ) is an appraisal of freshers and seniors to reflect on single clip devoted to assorted learning activities. NSU 2009 NSSE consequences related to civic battle stated: 7 % of NSU freshman pupils often participate in service-learning or community-based undertakings during a given twelvemonth. 80 % ne'er took portion in such activities. By their senior twelvemonth, 44 % of pupils have participated in some signifier of practicum, internship, field experience, cooperative, or clinical assignment. By the clip they are seniors, 56 % of pupils have participated in community service or voluntary work. The Multi-Institutional Study of Leadership ‘s ( MSL ) intent is to heighten cognition sing college pupil leading development every bit good as the influence of higher instruction on the development of pupil leading capacities. Participants are undergraduates, freshers – seniors. Following are answering distributions on specific features linked to civic battle from the NSU 2009 MSL. 38.5 % of the respondents identified take parting in community service. 36.4 % experienced an academic internship. 20 % participated in an academic acquisition community. The 2009 NSU campus stock list for Campus Compact on academic service-learning happening during the 2008-09 academic twelvemonth: NSU semester norm is 20 academic classs that integrate community service with academic content. 402 pupils participated in academic service-learning which averaged 18.1 hours/week across all classs bing 109143 hours. Nonspecific urethritis does non necessitate academic service-learning classs as portion of the class course of study. Snapshot of activity related to civic battle in academic units. College of Business and Technology – Financial Planning seminars for local community, Volunteer Income Tax Assistance ( VITA ) plan College of Education – Reading clinics for kids, Knowledge is Power Program partnership with Tulsa Public Schools College of Liberal Arts – instructor readying plan focused on the Cherokee linguistic communication and civilization College of Optometry – regional optometry clinics, international service trips College of Science and Health Professions – Speech Pathology clinics Snapshot of activity related to civic battle in co-curricular environment. American Democracy Project ( ADP ) chapter. ADP rank is chiefly module and staff. A little group of pupils have late engaged in ADP. We have sent ADP members to the national conference the last 2 old ages. ADP has developed a growing proposal for execution get downing autumn 2010. Recognized Student Organizations ( RSO ) . 96 pupil organisations are recognized by NSU. 38 % of the organisations organize community service activity as identified in their organisation description. Populating Learning Community. Housing hosts a life larning community focused on service. Large Event. The Senator Rozell Scholars coordinate the one-year Big Event, a 1-day community service undertaking. Over 600 pupils participated in Large Event in March 2010. Center for Student Leadership Development and Community Engagement. Student Affairs has designated an office in the University Center lower degree to function as a cardinal location for a freshly formed Center for Student Leadership Development and Community Engagement. A alumnus helper is dedicated to resource and plan development under the supervising of the Director of Campus Involvement. Campus Compact. NSU is a member of Oklahoma Campus Compact. Our activities over the last 4 old ages with Campus Compact include an AmeriCorps VISTA voluntary, MLK Volunteer Project grant receiver, and one-year study of service. Cherokee Nation Community Service Program. Cherokee Nation requires pupils having fiscal aid to finish a set figure of service hours per semester. Several service plans coordinated by Cherokee Nation and NSU entities are presently underway. 2015 Aspiration: Carnegie Community Engagement Classification The Carnegie Community Engagement Classification standards require the followers: Infrastructure: a campus-wide coordinating substructure ( centre, office, etc. ) to back up and progress community battle, establishment have a definition and a procedure for placing Service Learning classs Budget: internal budgetary allotments dedicated to back uping institutional battle with community, external support dedicated to back uping institutional battle with community, and fund-raising directed to community battle Learning results: institutional ( campus-wide ) larning results for pupils ‘ curricular battle with community, departmental or disciplinary acquisition results for pupils ‘ curricular battle with community, outcomes consistently assessed and used Integration in curricular activities: community battle integrated into Student Research, Student Leadership, Internships/Co-ops, Study Abroad, community battle integrated with course of study on an institution-wide degree – Core Courses Graduate Studies, First Year Sequence Capstone ( Senior degree undertaking ) , In the Majors General Education Faculty scholarship: associated with their curricular battle accomplishments, module scholarship associated with their outreach and partnerships activities ( proficient studies, course of study, research studies, policy studies, publications, etc. ) Outreach and Partnerships: Outreach focuses on the application and proviso of institutional resources for community usage with benefits to both campus and community. Partnerships focal point on collaborative interactions with community and related scholarship for the reciprocally good exchange, geographic expedition, and application of cognition, information, and resources ( research, capacity edifice, economic development, etc. , mechanisms to consistently supply feedback and appraisal to community spouses and to the establishment Recommendations for Traveling Forward Make a NSU Civic Engagement Council dwelling of representative from the American Democracy Project, Student Affairs – Center for Student Leadership and Community Engagement, each academic college, Futures Institute, Herb Rozell Scholars ( Big Event ) , NSGA, and Housing – Living-Learning Community on Civic Engagement, Continuing Education and Athletics. Interested campus community members beyond the identified representatives may go to council meetings. The intent of the council is to strategically incorporate civic battle through: Identifying University-wide ends related to % of pupils who participate in civic battle while at NSU. Develop University pupil larning nonsubjective ( s ) linked to civic battle. Create systematic campus-wide trailing or certification mechanisms to enter and/or path battle with the community Develop a systematic campus-wide appraisal mechanisms to mensurate the impact of institutional battle Provide professional development support for module, staff, and pupils who engage with community Supply the community with a cardinal mercantile establishment for a â€Å" voice † or function for input into institutional or departmental planning for community battle Serve as a cardinal communicating hub for civic battle activity happening throughout campus. Develop an academic enterprise that includes the followers: Get down a conversation on the feasibleness of necessitating service acquisition in every major and minor. Create an interdisciplinary child in civic battle with the aspiration of going a major. 12 credits required for a minor to get down with, so construct a major that is interdisciplinary on top of the minor. Necessitate that all pupils must finish at least one class in service larning leading and finish a service larning undertaking as portion of that class†¦ and all of those classs have a service larning constituent available so that pupils could take the class they want. Create a Service Learning Center that includes full-time module who teach required lower division classs in service larning leading, community development, squad and interpersonal relationships, societal and political motions throughout history, societal organisations and societal action, non-profit leading, etc. etc. The basic thought is a section with a major/minor in countries that may pull new pupils, supply a path to hold bing pupils take part in service acquisition. American Democracy Project creates a particular involvement path or certification within the civic battle major and/or child. Designate shared infinite for civic engagement academic and co-curricular plans coordinated through Academic Affairs and Student Affairs in the installations maestro program. This designated infinite could go a paradigm for interdisciplinary plans and services. Long-run end could be a new edifice dedicated to Making Place Matter through acquisition, invention, and outreach.

SAT Results in Physics to Impress College Admissions

SAT Results in Physics to Impress College Admissions Because most colleges that ask for SAT Subject Tests are highly selective, you will most likely want a score in the 700s if youre going to succeed in impressing the admissions officers. The exact score is going to depend on the school, so this article will provide a general overview of what defines a good Physics SAT Subject Test score and what some colleges say about the exam. Subject Tests vs. the General SAT The percentiles for SAT Subject Test scores cant be compared to general SAT scores because the subject tests are taken by an entirely different student population. Because the test is required primarily by some of the nations top colleges and universities, the students who take SAT Subject Tests tend to be high achievers. The regular SAT, on the other hand, is required by a wide range of schools, including many that are not selective at all. As a result, the average scores for SAT Subject Tests are significantly higher than those for the regular SAT. For the Physics SAT Subject Test, the mean score is 664  (compared to a mean of about 500 for individual sections of the regular SAT).   While no tool exists for you to calculate your chance of admission based on the Physics exam, you can figure out your chance of admission based on your GPA and general SAT scores. What Subject Test Scores Do Colleges Want? Most colleges do not publicize their SAT Subject Test admissions data. However, for elite colleges, you will ideally have scores in the 700s. Here are what a few colleges say about the SAT Subject Tests: MIT: The Massachusetts Institute of Technologys admissions website states that the middle 50% of students scored between 720 and 800 on SAT II Subject Tests in the sciences.Middlebury College: The prestigious liberal arts college in Vermont claims that they tend to receive SAT Subject Test scores in the low to middle 700s.Princeton University:  This elite Ivy League school states that the middle 50% of admitted applicants averaged scores between 710 and 790 on their three highest SAT II Subject Tests.UCLA: As one of the top public universities, UCLA states that about 75% of admitted students scored between 700 and 800 on their best SAT Subject Test, and the average score for the best SAT Subject Test was 734 (675 for the second best subject).Williams College: Over half of matriculated students scored between a 700 and 800 on their SAT Subject Tests. As this limited data shows, a strong application will usually have SAT Subject Test scores in the 700s. Realize, however, that all elite schools have a holistic admissions process, and significant strengths in other areas can make up for a less-than-ideal test score. Your academic record will be more important than any test scores, especially if you do well in challenging college preparatory courses. Your AP, IB, dual enrollment, and/or honors courses will all play an important role in the admissions equation. Colleges will also want to see strong non-numerical evidence of your preparedness for college. A winning application essay, meaningful extracurricular activities, glowing letters of recommendation, and other factors can make an application stand out even when the test scores arent quite what you had hoped for. Very few colleges use the Physics SAT Subject Test to award course credit or to place students out of introductory level courses. A good score on the AP Physics exam, however, often will earn students college credit (especially the Physics-C exam). Physics SAT Subject Test Scores and Percentiles Physics SAT Subject Test Scores and Percentiles Physics SAT Subject Test Score Percentile 800 87 780 80 760 74 740 67 720 60 700 54 680 48 660 42 640 36 620 31 600 26 580 22 560 18 540 15 520 12 500 10 480 7 460 5 440 3 420 2 400 1 Data from the College Board Examine the correlation between Physics SAT Subject Test scores and the percentile ranking of students who took the exam. Nearly half of all people who took the exam scored a 700 or higher, a far bigger percentage than with the regular SAT. 67 percent of test takers scored a 740 or below on the Physics SAT Subject Test. In 2017, only 56,243 students took the Physics SAT Subject Test.

How to Prepare Common Acid Solutions

How to Prepare Common Acid Solutions Common acid solutions can be prepared using the handy table below. The third column lists the amount of solute (acid) that is used to make 1 L of acid solution. Adjust the recipes accordingly to make larger or smaller volumes. For example, to make 500 mL of 6M HCl, use 250 mL of concentrated acid and slowly dilute to 500 mL with water. Tips for Preparing Acid Solutions Always add acid to a large volume of water. The solution may then be diluted with additional water to make one liter. Youll get an incorrect concentration if you add 1 liter of water to the acid. Its best to use a volumetric flask when preparing stock solutions, but you can use an Erlenmeyer flask if you only need an approximate concentration.  Because mixing acid with water is an exothermic reaction, be sure to use glassware capable of withstanding the temperature change (e.g., Pyrex or Kimax). Sulfuric acid is particularly reactive with water. Add the acid slowly to the water while stirring. Recipes for Acid Solutions Name / Formula / F.W. Concentration Amount/Liter Acetic Acid 6 M 345 mL CH3CO2H 3 M 173 F.W. 60.05 1 M 58 99.7%, 17.4 M 0.5 M 29 sp. gr. 1.05 0.1 M 5.8 Hydrochloric Acid 6 M 500 mL HCl 3 M 250 F.W. 36.4 1 M 83 37.2%, 12.1 M 0.5 M 41 sp. gr. 1.19 0.1 M 8.3 Nitric Acid 6 M 380 mL HNO3 3 M 190 F.W. 63.01 1 M 63 70.0%, 15.8 M 0.5 M 32 sp. gr. 1.42 0.1 M 6.3 Phosphoric Acid 6 M 405 mL H3PO4 3 M 203 F.W. 98.00 1 M 68 85.5%, 14.8 M 0.5 M 34 sp. gr. 1.70 0.1 M 6.8 Sulfuric Acid 9 M 500 mL H2SO4 6 M 333 F.W. 98.08 3 M 167 96.0%, 18.0 M 1 M 56 sp. gr. 1.84 0.5 M 28 0.1 M 5.6 Acid Safety Information You should always wear protective gear when mixing acid solutions. Be sure to wear safety goggles, gloves, and a lab coat as well. Tie back long hair and make sure your legs and feet are covered by long pants and shoes. Its a good idea to prepare acid solutions inside the ventilation hood because the fumes can be noxious, particularly if you are working with concentrated acids or if your glassware isnt absolutely clean. If you do spill acid, you can neutralize it with a weak base (safer than using a strong base) and dilute it with a large volume of water. Why Arent There Instructions for Using Pure (Concentrated) Acids? Reagent-grade acids typically range from 9.5  M (perchloric acid) to 28.9 M (hydrofluoric acid). These concentrated acids are extremely dangerous to work with, so they are usually diluted to make stock solutions (instructions included with the shipping information). The stock solutions are then further diluted as needed for working solutions.

Do Women Have Better Color Vision than Men Essay

Do Women Have Better Color Vision than Men - Essay Example Females have better connections and additional frequent communication between their brain's halves. This accounts for women's knack to have better insight. Men's brains are planned to chasing, which explicates their contracted scale of vision, while women's brains are capable to interpret a broader range of information. In the 1980s, vision examiners started to get some genuine physical discrepancies between the eyes of many women and those of most men. "Normal" color vision is doable because usually human have three different sorts of cone cells in their eyes, each one of which reacts to a different wavelength of beam. The procedure is principally opposite to that of a television set or computer monitor mechanism: on a TV, there are three colored marks - blue, green, and red - and a wide variety of "colors" we see are based on combinations of different degree of those colors. In the eye, cone cells comprises of three different photo tinctures. These are typically generalized as blue, green, and red, but their concrete values are nearer to bluish violet, green, and yellowish green. To keep away from mystification, psychologists characteristically refer to them to long-, medium, and short-wavelength receptive cones. For example, we are looking at a yellowish-green object, the long-wavelength cones are provoked the most, the medium-wavelength cones are kindled a bit, whereas the short-wavelength cones are not revived by any means, and the apposite signal is passed along the optic nerve to the mind, which then identifies the color as "yellowish-green." What the researchers were verdict when they truly looked at the structure of the eye is that most of the women - possibly more than fifty percent - owned a fourth picture pigment. Was this purely a genetic irregularity The premature research recommended that it would not. There is no superiority in women at deciding whether two very alike color scraps were in fact the same. They were only to some extent better than men at perceiving subtle marks of red light, a truth researchers accredited to individual distinction. On the other hand, Jameson and her companions were not influenced by this substantiation. Young girls are better at designating colors than boys, and matured men are not as fine at color-naming compared to women. They experienced the presented measures of color understanding and color-matching did not detain all the discrepancies between men and women, and formulated a new research that they felt was more correspond to real-world vision. (Deeb, 1996) It's to a certain extent complicated to observe an eye to conclude if it has an extra photo pigment - the method generally involves confiscating an eye itself. Jameson and her age group members may perhaps have had just a bit of intricacy recruiting volunteers to take part in a research involving such severe measures, so as an alternative they used a genetic examination to decide how many different photo pigments applicants were expected to possess and they guess this estimate this practice to be about 90 percent correct (Mollon, 2000). Out of 64 contestants in the research, 26 women were have 4 photo pigments, 16 of them were women with 3 photo pigments and 22 were males with 3 photo pigm
