Hence, serial homicide psychology is essentially described as the study of the mental and behavioral aspects of a serial killer. A serial killer is described as an individual who commits specific murders because he or she is driven by a particular desire and urge to kill individuals. A serial killer is defined as such when he or she is involved in the murder of a minimum of three people. In essence serial homicide is executed in manner that there is usually what is defined as a â€Å"cooling off† period between the murders with the intent of making the murders seem unconnected. The cooling off period is used by serial killer to strategize, plan and evaluate the public reactions of people in the society. The Federal Bureau describes that the mind of a serial killer is driven by several elements such as thrill, financial gain and the need of attention form the police as well as the society. The prey of a serial killer is usually unaware of the presence of a murder seeking their blood for various reasons. Majority of serial murders are usually executed in a similar manner, which makes tem easily linkable to the serial killer (Andrews Bonta, 2010). Essentially the motivation of murder by a serial killer is usually based on psychological issues. Hence, scientists as well as theorists seek to understand the functions inside the mind of a serial killer towards murder. In addition, the traits exhibited by a serial killer are not detailed within the Diagnostic and Statistical Manual of Mental Disorders (DSM) of American Psychiatric Association does not define any behavior exhibited by serial killers as part of mental illnesses. Majority of the serial killers usually exhibit antisocial personality disorders, which are not entailed as part of mental illnesses within the DSM manuals (Andrews Bonta, 2010). Individuals with Anti-Social Personality Disorders (ASPD) usually have long histories of confrontation with the law and end up arrested by law enforcement officers (Andrews Bonta, 2010). In addition, such individuals are also involved in physical confrontations with people they met in the various social settings. They are also descried as individuals with excellent oratory skills such that they are able to tell lies without notice from their listener. Some are also unable to stay in employment, as they tend to get hostile with other employees as well as the employer due to their confrontational behavior. Some psychologists regard psychopathic behavior as an advanced form of ASPD. Furthermore, they also view that psychopathic behavior is usually exhibited more in men than in women. Psychopaths usually have antisocial tendencies, which are more advanced because of the additional behavior, which they tend to exhibit, thus making them difficult to diagnose and eventually give treatment. The main traits exhibited are the lack of responsibility for actions as well the lack of remorse and guilt for their actions. They are also usually paranoid and suspicious of all activities around them as if they think that people around them want to victimize them. Serial killers generally love the power and attention they accrue from holding and killing their victims. They essentially need the thrill and attention they accrue from holding their victims hostage and doing away with the victim by death. Majority of the serial killers usually have histories of neglect and child abuse leading to a need to seek attention in manners, which they know, through violence. Hence the means to vent out the anger emanating from a history of neglect and violence results in use of identical or higher levels of violence to seek and attention and vent out their anger. The media attention granted to the serial killers is usually a motivating factor for the killers. This is because they learn that their efforts are recognized, hence they seek to commit heinous acts to gain attention, while venting out their anger. Once a serial killer is involved in murder, he or she grows the need to commit more identical acts to satisfy the innate psychological needs, which migh t be emotional, physical or sexual. Majority of the serial killers are described to have a psychological disorder, which is the main cause for their antisocial and unstable behavior. Hence, their activities are usually related to one of more of the psychological disorders detailed in the DSM manuals for psychological disorders. Some of most high profile serial killers in the world exhibited mental instabilities and obsession in their activities. For instance, Gary Leon Ridgeway alias the Green River Killer was charged and convicted of at least 48 murders of women. However, he confessed that he had killed more than double the number, which had been identified. Majority of the women he had killed were prostitutes. He was able to exercise such because as a serial killer he had the ability to lure the women with the promise of money for sexual favors. He gained the alias Green River Killer after the first five of his victims were discovered in the Green River. His main method of killing was by strangling and with the use of ligatures. This is an express indication of the lack of consideration and respect for human life. He used such methods to make sure that he that felt powerful as he took away the lives of the women that he killed (Waller, 2010). Another infamous serial killer famed for his actions was John Wayne Gacy, who was a member of the Junior Chamber Of Commerce. He confessed about the murders of numerous people some of whom were not accounted for by the authorities. He was a respected member of society. However, he had an abusive relationship with his abusive alcoholic father. There were suspicion that he was a child molester and homosexual. This is an indication that previous childhood experiences might have had role in his killings. Theodore Robert Cowell alias Ted Bundy was an infamous serial killer in the 1946 who was famed for his good looks. This enabled him to lure his victims with ample ease to their death. He used various approaches such as posing as a police officer, firefighter and other workers to gain trust from his potential victims. He was responsible for killing 40 women after raping them and eventually mutilating their bodies. He confessed to the murders. Eventually, he was executed. It is claimed that before he dumped his bodies, he applied make up to the dead woman and slept with them (Bartol, Bartol, 2008). Mass murder is essentially described as the act of killing more than four individuals at the same time or over a relatively short period. In addition, the Federal Bureau of Investigations (FBI) describes that mass murders are characterized by the time of occurrence, which separates them from the definition of serial murders or homicide (FBI Serial Murders Report, 2009). They usually occur during the â€Å"cooling off† period. Furthermore, mass murders usually occur in a specific location whereby all the victims are killed in a single location or a vicinity of a particular location. In essence, mass murder is defined as the intentional and indiscriminate murder of individuals by either individuals or organizations. Serial killers when involved in the murder of large numbers of people, usually execute such plans in a longer period. Serial murders are usually instigated and executed based on psychological needs and imbalance by the serial killers. On the other hand, mass murders are usually aimed at execution of large numbers of people without discrimination of the victims. Hence, the difference between mass murders and serial murders are based on the selection of the victims. Mass murders are at times based on killing of family, friends, colleagues and strangers based on an individual belief. Such events usually have motivating factors such as bullying, racism, loss of employment, lack of attention, discrimination and perceived alienation of an individual. Hence, a mass murderer executes his or her activities of killing people because of previous encounters and experiences with a targeted group of individuals. Mass murders are usually based on various contexts. Death of people a result of an act of war is by some in society considered as mass murder. On the other hand, others consider that mass murder amounts to death of people who do not have any reason to face such cruelty. They simply become victims of fate. Mass murders are also based on political contexts such as during the execution and murder of political supporters of a specific grouping. This is at times regarded as genocide based on the numbers of people executed in such circumstances (Geberth, 2006). The definition of serial homicide from the Bureau of Justice Statistics defines serial homicide as an act that involves the murder of several individuals in separate events, which are separated by time but are executed in a similar fashion or signature. This gives definition to the serial killer. A serial killer and a spree killer usually have identical traits in the execution styles of their activities. A spree killer is described as one with the ability of hunting for the victims whereas the serial killer uses seduction and luring tactics to lure the victims to their demise. In addition, serial killers actualize their need to kill based merely on sadistic urges, which are essentially defined as psychopathic. Furthermore, their sociopathic and unsociable traits make them unable to interact and sympathize with others about their suffering. Hence, the lack of remorse is usually a trait evident in majority serial murderers (Waller, 2010). In conclusion, serial killing is based on psychological instabilities and disorders of an individual. On the other hand, mass murders are usually executed at a specific moment. However, the two instances are identical in that serial killing and mass murder involve premeditation of such efforts before the actual execution of plans to kill large numbers of people. In essence, both perspectives involve taking the lives of people who are unaware of such preplanned events aimed at actualizing their demise. Reference Andrews, D. A., Bonta, J. (2010).

The impact of relationship between rape victims and men Essay

The impact of relationship between rape victims and men - Essay Example Social stigma as a form of secondary victimization also continues to haunt the rape victims as they move on with their lives after the attack. White & Robinson-Kurpius’ (1999) study revealed that men continued to subscribe to the mythology associated with rape that women/victims are culpable for what had happened to them because of the way they are dressed, their behavior, type of work or sexual experience (p.993). These were then used to rationalize or justify or absolve the acts of the aggression. Victims of sexual assaults experience a range of short and long-term effects such as anxiety and depression (Harris & Valentiner, 2002, p.286). Also associated with the sexual violence various forms and symptoms of post-traumatic stress disorder (PTSD) in majority of the victims. In addition, victims developed problems in interpersonal relationships and social functions (p.286). Victims of sexual violence develop interpersonal functioning problems especially when their pre-traumatic schema differed from the post-traumatic experience. The victims generally avoid sexual activity primarily because they developed a basic distrust towards other people and a misconception and belief in â€Å"random distribution of events.† All these, in addition to a general feeling of discomfort in resuming sexual activity contribute to the reluctance of rape victims to resume normal social relationships (Harris & Valentiner, 2002, p.302). Harris & Valentiner (2002) also noted that extreme self-paranoia is a consequence of â€Å"beliefs that the world and its inhabitants are harmful and that unfortunate events are distributed in a random pattern.†(p.302). Trust is a factor that is lost and the victims usually perceive other people as untrustworthy and dangerous. Self-blame contributes to reduction of self-esteem and most would perceive themselves as â€Å"socially

Issues in Internet Sales Law - Essay Example ld there be a contract and the case goes before the courts, according to the freedom on contract set forth in article 6 will not only enforce it but also to specific trade terms commonly used in international commercial transactions, such as Incoterms. (Butler, 2007) However in the absence of an agreement the CSIG provides for the passing of risk from the seller to the buyer with reference to the price ask or payment of the goods, due to loss or damage, as set forth in Part III Chapter IV: Passing or Risk, Articles 66-70 (Butler, 2007). Should Pretel contemplated not going to court, her lawyer would advise her otherwise because according to Butler (2007), Article 66 states; â€Å"Loss of damage to the goods after the risk has passed to the buyer does not discharge him from his obligation to pay the price, unless the loss or damage is due to an act of omission of the seller.† For the most part according to Steingold (2005), the same legal rules apply when one does business online as when one sells brick and mortar to a customer or by mail (Steingold F.S., 2005). This is possible the attorney went on to say, as long as the federal and state statutes and regulations are not violated. However, a look at the condition of sale on Cheryl’s website as well as the condition British received the goods, will set the stage for the arguments and case studies to be mentioned.

The case comes to life because the seller, Cheryl, refused to honor the request for a refund, saying that the risk had rest with the buyer. It seemed that Cheryl

Maths in Everyday Life Essay Example for Free

Maths in Everyday Life Essay You may find yourself wondering what use we have for some of the knowledge we obtain from math class in school. It is sometimes difficult for students to appreciate the importance of Mathematics. They often find the subject boring and hard to understand. With this project we will hopefully help our students realize that Mathematics is not just a subject on their time-table but a tool they use in their everyday life. Mathematics is one of the first things you learn in life. Even as a baby you learn to count. Starting from that tiny age you will start to learn how to use building blocks how to count and then move on to drawing objects and figures. Through the years, and probably through the centuries, teachers have struggled to make math meaningful by providing students with problems and examples demonstrating its applications in everyday life. Now, however, technology makes it possible for students to experience the value of math in daily life, instead of just reading about it. Math is everywhere and yet, we may not recognize it because it doesnt look like the math we did in school. Math in the world around us sometimes seems invisible. But math is present in our world all the timein the workplace, in our homes, and in life in general. When you buy a car, follow a recipe, or decorate your home, youre using math principles. This presentation also, is prepared using the principles of math. Math applies to daily life, with sections on gambling odds, buying and leasing cars, population growth, decorating, and cooking. Most sections include hands-on activities. Formulas are a part of our lives. Whether we drive a car and need to calculate the distance, or need to work out the volume in a milk container, algebraic formulas are used every day without you even realizing it. Simply put, mathematics is about relationships. Mathematicians have developed a language of precise relationships, illustrated through their formulas and equations. We live in a world where so far, as we have observed, everything is related and everything is experienced as different. We can learn about relationships in our world by looking at mathematical relationships that seem to match the situation being explored. For instance there is a relationship between distance traveled, time of travel, and speed of travel. Mathematics provides a relatively simple equation: Distance traveled = average speed multiplied by time of travel In simpler mathematical terms, d = s x t Math involves data analysis, number relationships and graphing, patterns and functions, statistics, and measurement. People who use math in their work, it doesnt occur that often that youd need to calculate 7 x 7 x 7 x 7 or 0. 1 x 0. 1 x 0. 1 x 0. 1 x 0. 1 or other such calculations. One example of how math do kind of connect with our everyday lives: when we speak about square feet, square meters, square inches, square miles, square kilometers or any other area units, or when we speak about cubic feet, cubic meters, cubic centimeters or any other such volume units. If you talk about SQUARE shaped areas, for example if you say My room is twelve by twelve square, youre meaning your room is 12 feet x 12 feet, or 122 square feet. I believe one reason that mathematics is not more generally applied has to do with a tendency to ‘think’ of mathematics only in terms of numbers, precision, quantification, and so on. We forget that mathematics is also about relationships, relatedness, relationships between relationships, interconnections, dependency (functions), changing relationships (calculus), factors that constitute relationships (variables), structure (order, relationships), asymmetric relationships (order), (graphical, numerical, and other representations (mapping), increase and decrease (addition, subtraction , multiplication, division, etc. ) and so on. The notion of a â€Å"function† is another mathematical tool we can apply to our everyday situations. Function in mathematics has to do with â€Å"relationships between variables – how a dependent variable changes when related variables change. In a simple equation y=3x, if we change the value of x, then y changes. Y is called the dependent variable, and x the independent variable. In other words the value of y depends on the value we give to x. And in this equation, we can give x any value we choose. In our everyday living, we do many things that are related to other things – although not as precisely as in mathematics – and we give values, assign meanings, and so on. Our whole living involves relationships. Our successes are a function of our efforts. The way others treat us is a function of how we behave towards them. Meanings, values, significance, understanding, etc. , are functions of ‘time’ – more specifically information available at a ‘time’. In a world where as far as we know everything is related, we can learn a lot about our everyday relationships by studying the approaches of a system that deals specifically with relationships. Variables and functions are only two examples of a vast number of other mathematics approaches we can apply to better understanding our everyday relationships. Math applies to daily life, with sections on gambling odds, buying and leasing cars, population growth, decorating, and cooking. Most sections include hands-on activities. One of the most complete and self-sufficient math units on the Web is Project Sky Math: Making Mathematical Connections Using the Science and Language of Patterns to Explore the Weather. They study the history of weather prediction, develop symbol sets, prepare graphs, predict changes, solve problems, and discover rules. General semantics involves applying the methods of science and mathematics to our everyday living. For instance, if we ‘think’ of things – anything – in terms of the â€Å"variable†, we will come to realize that like the mathematical variable that is sometimes a higher value and sometimes a lower value, we should expect things and situations to change. Sometimes this change will occur in the way we like; other times not. Sometimes more than we expect, sometimes less. Sometimes we will observe no significant change. We can expect our moods and ‘feelings’ to vary. ‘Thinking’ in terms of the variable better prepares us to anticipate and manage changes in our lives. This could reduce a great deal of stress in our lives – stress related to our forgetting that thing-processes are not constants. Family, partners, friends, work situations, health, etc. , won’t stay the way we found them or the way we expect them to go. ‘Thinking’ in terms of the variable, we would expect variations in our lives, and situations to vary related to different ‘time’, ‘places’, contexts, and so on. It is important to keep in ‘mind’ that with regards to our everyday relationships, unlike mathematical equations, precision is not the important factor-variable here. Important factors involve recognizing relationships, interconnections, and â€Å"interdependencies†. An important factor is to be aware that we assign our own individual values to what we see, hear, read, and so on. We could avoid, or better manage many conflicts, by remembering variables and functions. There are lots of real uses of mathematics in our life. All the mathematics terms base on counting. Today our all businesses base on counting. There is no concept of business without mathematics. Before the mathematics rules people use barter system. They give their goods to others and take the goods from other people. But this system cannot continue longer when need of humans increased day by day. Now you can think that counting has vital role in our daily life, just imagine if there were no mathematics at all, how it would be possible for us to count days, months and years. There is a cost for everything that we may use or purchase from markets so whats a cost? What are utility bills? Whats the ticket price? These are all applications of mathematics. We cannot deny the importance of mathematics in our daily life. When we got to shop to purchase something we need mathematics. When someone comes to our shop to purchase something we need calculations. There are many uses of mathematics in real life most likely in jobs like accounting, banking , store manager or just working at a simple fast food store. These are very simple applications of mathematics. Mathematics is at the core of all the communication technologies, its used in accounting, finance etc in short we are using mathematics in some form or another everywhere in our daily lives. But the most important use of mathematics in our technologies cannot be contradicted. Our most of the system base on computers and all the computer technology are stands on mathematical rules. All computers work on binary code, code of zero and one. So we cannot deny the importance of mathematics in real life. Everyday life would be quite difficult if you had no knowledge of math. To know whats the time, the most precious thing. On a basic level you need to able to count your money, multiply, subtract and divide. You need knowledge of math if you want to work out how much material to buy for a job. More advanced mathematics is essential if you take up any kind of technical career such as engineering. Working on algebra and geometry also helps with reasoning skills and assists later in life with technical problem solving. Living your day to day life without maths would be extremely difficult. Even if you were a nomad in the desert you would want to count your goats, wouldnt you? The key to opportunity These are the years of small beginnings until the day comes that you have to be able to do something as intricate as algebra. Math is the key that will unlock the door before you. Having the ability to do algebra will help you excel into the field that you want to specialize in. We live in a world where only the best succeed. Having the ability and knowledge to do algebra will determine whether you will take the short cut or the detour in the road of life. Prerequisite for advanced training Most employers expect their employees to be able to do the fundamentals of algebra. If you want to do any advanced training you will have to be able to be fluent in the concept of letters and symbols used to represent quantities. Science Moreover, it is also believed that Mathematics is the mother of all sciences. This also shows us that all the sciences that are evolved have a sound foundation in mathematics, if we go further in debate it would be justified to say that the blessings of all these modern sciences and technologies are only possible with mathematics. Mathematics is used as a problem solver in every field of science. Mathematics is playing a very important role in our daily lives. In fact mathematics is involved directly or indirectly wherever we go and every thing that we may use. When doing any form of science, whether just a project or a lifetime career choice, you will have to be able to do and understand how to use and apply the concepts of math. Analysis When it comes to analyzing anything, whether the cost, price or profit of a business you will need to be able to do math. Margins need to be set and calculations need to be made to do strategic planning and analyzing is the way to do it. Data entry What about the entering of any data. Your use of algebraic expressions and the use of equations will be like a corner stone when working with data entry. When working on the computer with spreadsheets you will need algebraic skills to enter, design and plan. Decision making Decisions like which cell phone provider gives the best contracts to deciding what type of vehicle to buy, you will use algebra to decide which one is the best one. By drawing up a graph and weighing the best option you will get the best value for your money. Interest Rates How much can you earn on an annual basis with the correct interest rate. How will you know which company gives the best if you cant work out the graphs and understand the percentages. In todays life a good investment is imperative. Writing of assignments When writing any assignments the use of graphs, data and math will validate your statements and make it appear more professional. Professionalism is of the essence if you want to move ahead and be taken seriously. Math is basically about solving problems and calculating different things. So if you are good in math, you are good at solving problems and calculating things first hand. Can you see the importance of algebra? Your day can be made a lot easier with planning. In financial decisions this can save you a lot of finances or maybe get you the best price available. It all comes down to planning and using the knowledge and algebraic skills you have to benefit your own life. Use the key you have and make your life a lot smoother. Mathematics is very important for life since it helps us to quantify all the visible and invisible things with which we are dealing in daily life. It is human nature that they do not have complete confidence in the subjective or relative things, in the modern day of today the objective things are preferred and trusted more than the subjective things. Mathematics helps us to have an objective view of the different things we are dealing with. It helps us in making calculations about the things which are not physically developed like for buildings before construction. Living a life unknowing Maths would be living in random oblivion. Mathematics is primarily used for the purpose of scientific calculation of figures and objects. In real life the use of Mathematics can be applicable to every aspect, field, profession and subject etc. In IT field, in Statistics, in Accounts, in Algebra, in Geometry, for instance, Mathematics is used for calculating, multiplying, subtracting, division, differentiating, manipulating and managing the data in desired form. In other professions Mathematics can merely be used for the calculation of currency, recording the profits and loss. In ordinary life Mathematics can be used for the calculation of any specific or general sort. Concisely it can be said that Mathematics can be used for the authentic and scientific variation between and calculation of numbers, amounts, quantities etc; measurements of the frequencies of light and sound, of distance. Maths is all around us. It is present in different forms; it is very important that we take note of it. Things are measured or accurate due to maths. Mathematics has a prominent role to play in our daily life. We even didnt realize that maths is involves in every sort of activities. Whenever we pick up the phone, manage the money, travel to some other place, unintentionally in all these things maths is involved. Another very simple application is calendar year. How we know that today is Tuesday? It was Thursday on May 1, 2012? Its actually mathematics that gives/provides us all this information. Mathematics do play a big part in our daily lives. Mathematical functions like addition, subtraction, multiplication, division and so on are used in our daily activities. From poor to rich , all have to some how use mathematics in their real lives. Consider a housewife, who has to run her house in the given budget. She divides money according to her needs and estimates about the expenses and then spends it according her range. From the advent of civilization, man learn to count using stones and beads. In the earliest civilization, barter-system was used. Now-a-days, all day to day transactions in a multi-national or national companies involve mathematical operations . The application of maths is seen every moment, right from the moment we wake up from bed in the morning till the moment we again go back to bed at night. As soon as we wake up, we first of all give a big yawn-that makes us think for how long we have yawned? 3 to 5 seconds? Here maths comes! Again when we look at the clock, we realise how late we have got up! 8:30 a. m! Here the part called Time of mathematics is put to focus. Even when we brush our teeth, we should know how much amount of toothpaste we must useits written on the tubes that children below the age of 6 years should use only a pea-sized amount of it. Again, we must keep a track of how much time we have to take to brush our teeth. Then comes the time of studying.. we keep a regular routine of how long we must study a particular subject and i often hear my mom saying me. You must keep a little extra time for Maths and Science.. Then comes bathingwe take a certain amount of water which we can count in litres. Now if i have to go on saying for the whole day about the use of maths in real life, i would not be able to complete it in a day! The list is endless. Mathematics is very important for life since it helps us to quantify all the visible and invisible things with which we are dealing in daily life. It is human nature that they do not have complete confidence in the subjective or relative things, in the modern day of today the objective things are preferred and trusted more than the subjective things. Mathematics helps us to have an objective view of the different things we are dealing with. It helps us in making calculations about the things which are not physically developed like for buildings before construction. We do calculations and ensure if their design is safe or not, similarly mathematics helps us to plan things for future either is any production environment for products or services. It helps us to have an idea that how much earning or spending has been done and would it be beneficial to do a certain activity or not. In todays world mathematics is being applied everywhere like in the economy of a country, construction of buildings, marking and evaluation of persons. It would be appropriate to say that mathem atics has helped a lot in achieving the fast speed life with all its comforts and delights If we are quick at mental arithmetic, it will help you a lot in saving hundreds of pounds or dollars in the supermarket. And if you have knowledge of statistics it will help you see through the baloney (non sense, lies) in television adverts or newspapers. You can also understand different kinds of information about the football or cricket team. Even simple maths equations are just around us, like spherical shapes of soap bubbles, ripples on the surface of water. Maths help engineer in making different shapes with geometrical shape the structure of the building was not possible. The beauty of maths is not only around us but a strong know how of maths help us in every day life too. Just start looking around you and you will find that how maths is help full to you in your life We do calculations and ensure if their design is safe or not, similarly mathematics helps us to plan things for future either is any production environment for products or services. It helps us to have an idea that how much earning or spending has been done and would it be beneficial to do a certain activity or not.

It would be appropriate to say that mathematics has helped a lot in achieving the fast speed life with all its comforts and delights. Without math, one would not be able to function in the REAL world. We use math to purchase things we want, we use math to measure, tell time and so on. We all need the basics but having a more advanced knowledge in math such as geometry, algebra and metric system always helps. As they say knowledge is priceless.

The Human Eye in Space :: essays research papers

Human visual hardware is a result of a billion years of evolution within the earths atmosphere where light is scattered by molecules of air, moisture, particular matter etc. However as we ascend into our atmosphere with decrease density, light distribution is changed resulting in our visual hardware receiving visual data in different format. Some Aspects to Consider: 1. Visual acuity is the degree to which the details and contours of objects are perceived. Visual acuity is usually defined in terms of minimum separable.Large variety of factors influence this complex phenomenon which includes : # Optical factors- state of the image forming mechanisms of the eye. # Retinal factors such as the state of the cones. # Stimulus factors such as illumination, brightness of the stimulus, contrast between the stimulus and background, length of time exposed to the stimulus. * Minimum separable: shortest distance by which two lines can be separated and still be perceived as two lines. "During the day, the earth has a predominantly bluish cast..... I could detect individual houses and streets in the low humidity and cloudless areas such as the Himalaya mountain area.... I saw a steam locomotive by seeing the smoke first..... I also saw the wake of a boat on a large river in the Burma-India area... and a bright orange light from the British oil refinery to the south of the city (Perth,Australia.)" The above observation was made by Gordon Cooper in Faith 7 [1963] and which generated much skepticism in the light of the thesis by Muckler and Narvan "Visual Surveillance and Reconnaissance from space vehicles" in which they determined that a visual angle of ten minutes was the operational minimum, and that the minimum resolvable object length [M.R.O.L] at an altitude of 113 miles would be 1730 ft. This limitation of acuity was revised the next year to 0.5 seconds of arc for an extended contrasting line and 15 seconds of arc for minimum separation of two points sharply contrasting with the background. Orbiting at 237 miles in the skylab it was possible to see the entire east coast [Canada to Florida Keys] and resolve details of a 500 feet long bridge based on inference. Of Interest is the fact that even though the mechanical eye [camera systems] can resolve objects greater than fifty times better than the human eye, without the human ability to infer, interpretation of the data is meaningless. Conclusion: Visual acuity in space exceeds that of earth norm when objects with linear extension such as roads, airfields, wake of ships etc. 2. Stereoscopic vision: the perception of two images as one by means of fusing the impressions on both retinas. In space one has to deal with a poverty of reference points.
