An Essay On Leonardo Da Vinci

What do we consider a genius, and who? When studying different definition, and with prior knowledge from speaking to psychiatrists and other mood evaluators, I now have a good sense of the term genius. A genius is someone who has incredible intellectual ability, as well as creative. One who is not only mentally progressed, but emotionally and creatively as well. Mastering a number of different and diverse skills and having all sorts of knowledge would qualify you. Leonardo Da Vinci, is thought to be one of the most intelligent people to ever have lived. Considered a Renaissance man, Da Vinci was not only an accomplished scholar but also a painter, architect, musician, scientist, mathematician, engineer, anatomist, cartographer, inventor, geologist, botanist, and writer. Da Vinci mastered a number of difficult skills, and had knowledge nobody else had found, especially for his time. His advancements, inventions and art were beyond what you would call good, they were genius. Born April 15th, 1452 out of wedlock, his father Piero and Caterina da Vinci were considered peasants. He was raised by his father, some believed he was not worthy of an education due to this. However, Da Vinci was advanced at the fine arts by age 15 and began his studies in a studio with Verrocchio a Florentine painter. Verrocchio painted for "The Baptist of Christ". He let Leonardo paint with him, though eventually ending his career because he was humiliated that he had been outshone by his student. Da Vinci was accepted into the Painters Guild of Florence. The most famous of Leonardo Da Vinci's art would be the portrait of "Mona Lisa" also known as La Gioconda (wife of Frances Giocondo). You can find it in the Louvre Today. You may have also heard of "The Last Supper", a religious piece of Jesus eating his last supper. Many people still study both these paintings today, still under covering secrets. In the episode "The Da Vinci Conspiracy" on Ancient Aliens, they study both of these paintings. They point out a UFO int the background of the "Mona Lisa". The historians on the show strongly believe that Leonardo Da Vinci had extra terrestrial knowledge, and help due to what he had achieved. He was significantly advanced way before his time, in all subject matters. Da Vinci's had countless inventions, stemming from his engineering knowledge. The most advanced and memorable ones, that we still use today include the helicopter, tank, concentrated solar power, and the calculator. It is hard not to wonder, how was this possible? How did a man of the Renaissance period have this advanced knowledge! It doesn't add up with the rest of his era, or what the rest of the world knew at that point. We still use his notes and mapped out ideas for the inventions he created that we are still using hundreds of years later. Ancient Aliens suggests that Da Vinci had some other wordily knowledge that he some how acquired. Personally, I am open minded but I am not suggesting this is necessarily true, but you have to wonder. I am not opposed to the idea and theories of extra terrestrials, I'm just not set on it either. However, this raises a greg point, how did he acquire this knowledge and intelligence in the era he lived in? Leonardo Da Vinci is by far one of the most, if not the most, interesting and intriguing person to study in history. Da Vinci was known for writing in "code". He had planned to publish a encyclopedia, sharing is knowledge of science and the human anatomy, unfortunately like many other of his plans this one did not get finished. However, 4000 pages of documents have been found from his notebooks and journals of exactly that. The "code" people refer to is his style of note taking. Not only did he spell words peculiarly, but he also wrote form right to left, a mirror image. Another thing that Ancient Aliens covers is this code, it almost seems like he was afraid someone would steal his ideas. There are many other theories about the code but we'll never know the real reason why. May 2, 1519 was the day Leonardo Da Vinci passed away. He lived to be 67 years old, which was a good age to have lived at that time but not for him. He left hundreds of projects unfinished, and the mystery of his knowledge for people to find. Think if he had lived to be eighty, or ninety what other great things he would have discovered. Da Vinci is my, as well as many others, favorite philosopher, scientist, and artists. To this day no one can compare to the way he mastered numerous fields of study and made history for being a genius. It makes you wonder what else is possible in this world if a man as smart as him could of lived. Leonardo Da Vinci is the most studied, interesting and cherished of all the scholars who have lived.

Steam Engine Research Paper Example | Topics and Well Written Essays - 3000 words

Steam Engine - Research Paper Example The basic purpose of the stationary steam engines is to pump and drive mills by generating power. While introduced in the 18th century, these engines continued to be produced in huge numbers throughout the 19th century, and most of the part of the 20th century until advancements made in the electrical field leading to the practical application of electric power and the development of the internal combustion engine took their place. The use of the fixed steam engines accelerated between the time period of 1750 and 1850 but started to gradually decline afterwards when more advanced and adaptable electricity powered engines began to be introduced. Though the use of internal combustion engines became more widespread later, this paper aims at stressing the fact that the importance of efforts leading to the discovery of steam power and invention of first commercially successful steam engine cannot be denied and should never be overlooked when contemplating the technological inventions intr oduced prior to 1850. Stationary steam engines have often been mistaken for other kinds of engines introduced during the time steam engines were under development process. But a little research into this matter proves that they can be distinguished and stand in contrast to locomotive engines used for railways, traction engines used for manufacturing roads, steam cars, and agricultural engines used for ploughing and harvesting fields. The steam engine is arguably considered the most important technology of the industrial revolution and the literature reviewed in this paper aims at underlining this claim that the steam engine due to multiple factors was indeed an... This essay stresses that the world witnessed a sustained growth in the obvious influences exerted by technology related revolutions which begin to revolutionize every aspect of daily life for the better. Period extending from 1750 to 1850 is characterized by the transitional change of the manual and animal-based labor into critical machine-based manufacturing. This paper makes a conclusion that the steam engine has always remained in limelight in the history. After Savery, Newcomen played a gigantic role of critical nature in advancing the efforts initiated by the previous engineer and introduced a version of steam engine which not only overcame the issues associated with the earlier model but also helped in greatly facilitating the human life by fostering the transition of manual-based labor into machine-based manufacturing. Then Watt’s highly effective double-acting rotative steam engine and later versions of steam engines invented in later years served as the basis for a whole new wave of modern or revolutionary steam technology. General consensus is that though the steam engine was an essential early element of the industrial revolution, still this technology remained underused for most of the part of that period as most of the industries then continued to rely on wind and water power along with manual and animal-based labor to run machines. The discovery of steam power formed the backbone of the steam engine manufacturing process and multiple scientists and engineers whose work precedes 1850 are involved in continually developing this technology.

Paper Part C - Statistics Project Example Similar to the coefficient of variation, the coefficient of determination normally ranges between +1 and -1. The coefficient of determination between the credit balance and size is established at 0.566; this means that 56% of the total variation can be explained by the linear relationship that exists between the credit balance and size of the household. The remaining 44% of the variation cannot be explained by the linear relationship which exists between the credit balance and size of a household. The above results of a two tailed t-test help a statistician to understand the probability of the differences of a given data; it indicates whether data are attributed to sampling errors. The t-test is mostly used by statisticians to reject a particular hypothesis or not. Mostly, if the p-value, which indicates the level of probability, is less than a certain significance level, one can reject a hypothesis. The above two tailed t-test was performed on credit card balance (variable 1) and size of household (variable 2). The P (T

First and Second Language Acquisition Essay -- Biology Essays Research

First and Second Language Acquisition In our everyday lives, the origin of our ability to communicate is usually not often taken into consideration. One doesn't think about how every person has, or rather had at one time, an innate ability to learn a language to total fluency without a conscious effort – a feat that is seen by the scientific community "as one of the many utterly unexplainable mysteries that beset us in our daily lives" (3).. Other such mysteries include our body's ability to pump blood and take in oxygen constantly seemingly without thought, and a new mother's ability to unconsciously raise her body temperature when her infant is placed on her chest. But a child's first language acquisition is different from these phenomena; different because it cannot be repeated. No matter how many languages are learned later in life, the rapidity and accuracy of the first acquisition can simply not be repeated. This mystery is most definitely why first language acquisition, and subsequently second language acqu isition, is such a highly researched topic. On the surface one would look at child first language acquisition and adult second language acquisition and see similarities. In each case the learner first learns how to make basic sounds, then words, phrases and sentences; and as this learning continues the sentences become more and more complex. However, when one looks at the outcomes of these two types of acquisition, the differences are dramatic. The child's ability to communicate in the target language far surpasses that of the adult. In this paper differences in these two processes that most always produce such different outcomes will be explored. Before this exploration begins, however, I would like to state ... ... learning. In conclusion, because of so many varying factors, both the processes and outcomes of child first language acquisition and adult second language acquisition are extremely different, and are only connected by a common goal.

Ethics in Psychology Essay

The definition of ethics is as follows: â€Å"a theory or system of moral values; the general nature of morals and of the specific moral choices to be made by a person†. (dictionary.com ) In modern day society, we have bio-ethicists; professionals who are trained to judge what can be considered ethical, as well as strict guidelines set forth by the APA (American Psychological Association). However, during the early years of the formation of Psychology, there were no bio-ethicists or universal guidelines, therefore some of the early experiments such as the â€Å"Little Albert†, and â€Å"Mother Attachment† would be considered unethical and therefore would not be permitted today. In 1920, behaviorist John B. Watson and his assistant Rosalie Rayner conducted an experiment now called the â€Å"Little Albert†. The desired outcome of the experiment was to show empirical evidence of classical conditioning in humans. (T. Bartlett) A similar study that preceded â€Å"Little Albert† was conducted by Russian physiologist Ivan Pavlov, which demonstrated the conditioning process in dogs. It is said that Watson wanted to continue and further Pavlov’s research to eventually show that emotional reactions could be classically conditioned in humans. Watson and Rayner first selected a nine month old baby from a local hospital, his name was Douglas Merritte. The child was then exposed to a series of stimuli including a white rat, a rabbit, a monkey, masks, and burning newspapers; his initial reactions were observed and recorded. The boy initially showed no fear of any of the objects he was shown. However, the second time the boy was exposed to the white rat, it is accompanied by a loud starling clang, that clearly frightens the child. This portion of the experiment is repeated multiple times until the mere sight of the white rat, or creatures that have a similar appearance, frighten the child even when unaccompanied by the startlingly clang. The researchers have successfully conditioned Little Albert to be afraid. (T. Bartlett) Today â€Å"Little Albert† is considered to be a cruel experiment of questionable value, clearly in violation of all five of the APA’s general ethical guidelines. The APA states that psychologists must: â€Å"respect the dignity and worth of all people, and the rights of individuals to privacy, confidentiality, and self-determination. Be aware that special safeguards may be necessary to protect the rights and welfare of persons or communities whose vulnerabilities impair autonomous decision making. Be aware of and respect cultural, individual and role differences, including those based on age, gender, gender identity, race, ethnicity, culture, national origin, religion, sexual orientation, disability, language and socioeconomic status and consider these factors when working with members of such groups. Try to eliminate the effect on their work of biases based on those factors, and they do not knowingly participate in or condone activities of others based upon such prejudices.†(APA) The first problem with â€Å"Little Albert† stems from the harm caused to the individual in question. Douglas Merritte was ultimately driven to feel extreme fear and even terror when exposed to anything that remotely resembled the white rat. This was mentally damaging for the child, and may have impaired his ability to integrate himself into society at a later date. (Cherry. K) Secondly, the right to withdraw was not present in the experiment; even when the boy became distressed and even ill the experiment continued. Therefore, today, the â€Å"Little Albert† experiment would be considered highly unethical. During the 1960’s, American Psychologist Harry Harlow, conducted a series of controvertial experiments known as the â€Å"Mother Attachment Experiments†. These experiments were used to analyze the mother-child relationship in primates. In Harlow’s initial experiments, infant monkeys were separated from their mother’s shortly after birth and were raised instead by surrogate mothers made either wire or soft terry cloth. In one experiment both types of surrogates were present in the cage, but only one was equipped with the ability to nurse the infant. Some infants received nourishment from the wire surrogate, and others were fed from the cloth mother. Harlow established that mother love was really behavior based, meaning the offspring would seek physical comfort, rather than feeding. Harlow’s isolation studies also demonstrated the need for maternal interaction with their infants and the importance of play as part of the normal process of psychosocial growth. Harlow has received multiple awards for these experiments, they have been deemed â€Å"of extreme significance for understanding those aspects of human behavior related to depression, aggression or sexual dysfunction, which originated in the formative years of mother-infant interaction.†(Theodore Lidz of Yale University Medical School). However, due to the fact that the experiments caused extreme psychological effects on the primates used in the trials, they could be seen as highly unethical. In the APA’s ethical principles of psychology, section 8.09 clearly states that psychologists must have a: Humane Care and Use of Animals in Research. Subsections B and D of section 8.09 are relevant when considering Harlow’s treatment of the primates. Subsection B states: â€Å"Psychologists trained in research methods and experienced in the care of laboratory animals supervise all procedures involving animals and are responsible for ensuring appropriate consideration of their comfort, health and humane treatment† (APA). In the â€Å"Mother Attachment† experiments, Harlow himself was not trained in the research methods and experienced in the care of the primates, nor was there any consideration for their comfort or mental health after the experiment. Furthermore, subsection D states that: â€Å"Psychologists make reasonable efforts to minimize the discomfort, infection, illness and pain of animal subjects† (APA). Harlow failed to minimize the negative effects of his experiments on the primates in a long term setting; most primates involved in the study were clinically depressed after the termination and in some cases during the experiment.Therefore, in accordance to the APA’s ethical guidelines Harlowâ €™s experiment would be seen as morally questionable and in most cases unethical in modern society. There is no question that the science which is psychology has been built and greatly advanced through the means of what some would consider unethical means and experimentation. â€Å"Little Albert† is seen today as a cruel experiment of questionable value. However knowledge was gained from this â€Å"unethical† experiment that has helped modern day psychologists. The â€Å"Mother Attachment† experiments, have won multiple awards for their â€Å"extreme significance† (Theodore Lidz) in the analysis of behavior based on the mother-child relationship; despite the fierce criticism and controversy surrounding the experiments. Should both experiments be considered morally wrong and unethical? Perhaps. Did both experiments play a large role in the advancement of psychology? Without a doubt. Therefore in Harlow and Watson’s cases, the end justifies the means. References American Psychological Association (APA). Ethical Principles of Psychologists and Code of Conduct.

Roxas nodded confidently. But that place is crawling with heartless. Ive been there like twice already, and I dont want today to be the last time, Xion said. Exactly. Man, Roxas, you sure do Scare me with big talk like that. How about we just walk around the city and see what we can find. Uh, yeah, thats a better idea, Roxas said, sounding a little embarrassed. The trio jumped off the roof and landed in a narrow street. Axel walked in front of them. I think after we get outta this street and cross a few alleys, there should be a big fountain up ahead. A big fountain? We never saw anything like that, Roxas said. Not my fault youre both bad at recon missions. I like to make the most out of my stay. What are you talking about, youre usually the earliest one for ice cream, Xion said. Not lately though. Only because Im the one who usually buys. Besides, Im just efficient at my job, thats all. Hey Axel, how long have you been in the Organization anyways? Roxas asked. Longer than you two have. He quipped. We know that, like...how many days has it been? I lost track. I tell ya, days in the Organization go on and
