Reflux
Reflux is a distillation technique involving the condensation of vapours and the return of this condensate to the system from which it originated. It is used in chemistry to supply energy to reactions over a long period of time.

You should never allow the top of the condenser to be stoppered because if you attempt to heat sealed glass apparatus it may explode. Also, you should heat gently because there is a huge risk, when not heated gently, of the equipment exploding and breaking. Also, heating under gentle reflux means the solution can vaporise correctly.

Distillation
Distillation is when you purify a liquid by a process of heating and cooling.
Water enters at the end of the tube. The thermometer is placed inside the distilling flask. Anti-bumping granules are used to provide many places where bubbles of gas may form as the water boils. The bubbles are small and rise steadily to the surface of the liquid where they burst. Without the granules, fewer but larger bubbles form. They rise and burst with such force that they shake the test tubes which can be a hazard.

Recrystallisation
We recrystallise in order to purify chemicals. In order to recrystallise, we first have to add a small quantity of appropriate solvent to an impure solid. Then we have to apply heat to dissolve the solid. After this, we have to cool the solution to crystallize the product. Finally we use a vacuum filtration to isolate and dry the purified solid.

Melting point
We use this to determine whether the correct product has been synthesised and to check its purity. Any amount of impurities will depress the melting point.

......the day of the philosopher as isolated thinker--the talented amateur with an idiosyncratic message--is effectively gone. | ” | —Nicholas Rescher, "American Philosophy Today," 'Review of Metaphysics' 46 (4 | It is possible to believe at something which could or couldn’t be true. Atheism is an example of this something. Atheists claim that there is no God because the evidence they experience shows that God is not real; however, to have a static claim as strong as atheism is anti-scientific: because the belief itself lacks foundation associated with our ‘natural laws’ and thus, having a set belief that is static is counter scientific spirit which contradicts that base of atheistic claim.  Thus, to be an atheist using scientific claims as basis is illogical; however, this doesn’t mean that a person cant be an atheist; but only that person who claims to be an atheist because of scientific reasoning is wrong in his assumptions. atheists say there is no God, but before you can deny something, you must first affirm its existence, as a rule... in saying there is NO God, you actually affirm there is one. Hence I must conclude that the answer to our openeng question is a simple and flat no. No, it is not necessary for a truly contemporary person to be an atheist or to disbelieve in the existence of God. And I find no arguments, no reasons, no evidence or facts, not in Bishop Robinson's writings, nor in Bishop Pike's, nor in the writings of Tillich, Bultmann, and Bonhoeffer, or in...

Frankenstein Loss

...Frankenstein Notes ------------------------------------------------- Some Interesting Points * There is a chilling logic in the creature's arguments. Why should he not respond in kind to the way that he has been treated by both his maker, who should have cared for him and looked after him, and by mankind as a whole? If the creature is inhuman, it is only because he is imitating the inhumanity of the human species. Therefore, I think that the novel presents Victor as being more inhuman. * Victor is alien in his society in the way that he removes himself from others, for example when he goes about creating the daemon/creation. Victor is very secretive and seems to like it that way... he doesn't really try to understand people like the creation does. The creation tries again and again to belong in the community, its his greatest desire. With Victor, on the other hand, there seems to be a gulf between him and the rest of society. * Justine’s trial testifies to the inhumanity of man. What is important to note is the way this links in to a vital theme of the novel, which is the presentation of the creature himself. He starts off innocent and wanting a relationship with his maker. It is the way that he is shunned by his maker and by humanity and treated cruelly that forces him into cruelty, but this cruelty is only paralleled by the monstrous nature of humanity as displayed in incidents such as the trial of Justine. We cannot expect the creature to be good when...

The Existentialist

...world,” and the difficulty inherent in such a task. A brief review of May’s biography is useful in understanding the philosophical path which he chose. May was born in Ada, Ohio, the first of six children born to parents who had great difficulty in their marriage. His mother and sister both suffered from mental illness, and their instability caused May to spend much of his internal life in an introspective solitude produced by psychic pain. After briefly attending Michigan State University and Oberlin College, May traveled across Europe where he taught English. He was intensely lonely, and it was at this point that he had one of two epiphanies which would shape his belief in existentialism. May began thinking of his own and other’s inner beauty, and he enrolled in Union Theological Seminary in order to study his newfound optimism. It was during this time that he studied psychoanalysis with Alfred Adler and philosophy with Paul Tillich. He practiced psychotherapy privately in the 1940’s and received his Ph.D. from Columbia University at the age of 1940. During this period, May experienced a second life-changing event: he spent three years in a sanitarium after contacting tuberculosis. This period of solitude allowed him time to read and theorize about man’s ultimate responsibility for his own existence. May noted that this view of man as controller of his ultimate destiny could also be translated into the realm of therapeutic encounters (Feist, 1990). May’s epiphany...

Hawkeye yells at a woman to keep her chicken from squawking, fearful that the enemy would find them, only to be stunned when the woman smothers her chicken while trying to keep it quiet. The audience is just as horrified as Hawkeye when he realizes the woman didn’t smother a chicken; she smothered her infant child.

Effects of Religion

...An Introductory Note by V.V. Raman We are multi-dimensional creatures. Even as biological entities we have several layers of existence: physical, intellectual, psychological, emotional, and yes, spiritual too. By the last I mean an inner experience and longing to be connected with the Cosmos. This longing expresses itself in a variety of ways, in most instances as a religious call. Evolutionary biologists and cultural psychologists may explain this away in the paradigms that are satisfactory for understanding the observed world. For practitioners, however, religious yearning derives from an external intangible source that is not directly amenable to empirical verification. If there can be neutrinos and dark energy that defy easy detection even through powerful and sophisticated instruments, one could argue, why can’t there be other intangibles whose existence is beyond meters and scopes? The matter continues to be debated, but this is not our concern here. No matter what the source, this heart-felt beckoning and fulfilling framework almost defines the religious person’s existence. There are many in our group who are religious persons. Religion informs and inspires the values and visions that are part of one’s existence. It provides a backdrop for one’s life, present and future, terrestrial and beyond, real and visualized. The spiritual yearning has taken concrete forms in human history as different religions with deep historical, geographical cultural links. Though...

...Secularism A Religion Profile from International Students, Inc. Secularism: An Overview Number of Adherents Demographer Davit Barrett estimates that there are 150 million atheists and 768 million nonreligious people in the world. The combined total comes to more than 918 million people (Barrett). Toward the end of the Renaissance, the modern method of empirical science began to develop. The key players were Nicholas Copernicus (1473-1543), Johannes Kepler (15711630), and Galileo Galilei (1564-1642). Although it may seem ironic now, each of these men believed in the Christian God. They viewed science as studying the handiwork of an almighty Creator and discerning His natural laws. Galileo considered God to have written two “books”: the Bible and nature (Hummel, p. 106). Contrary to popular belief, the cause for the diversion between Christianity and science originated not with the Church but with the university professors who were threatened by Galileo’s revolutionary ideas. These professors were steeped in the Greek scientific method, which included observation to a small extent, but mostly explained the workings of nature through rational deduction from first principles, or assumptions, an entire view of the universe had been built up. Consequently, the professors embraced such misconceptions as the sun having no imperfections, the moon being a perfectly smooth sphere that shone with its own light, and the earth alone having a moon since the earth was at the center of the...

In regards to the subject of moral judgment, psychologists and scientists alike have been baffled at the way human beings rationalize what behaviour is ‘moral’ or ‘immoral’. Are the things our society encourages us to see as bad concrete rights and wrongs, or does everyone develop their own right and wrongs based on their beliefs? When seeing Love Crime and reading “A Good Man is Hard to Find” I saw prime examples of human beings choosing to react irrationally...

Personality Theories

...Introduction to Behavioral Science: Personality Theories Dardree Weah University of Phoenix Sigmund Freud is the founder of psychoanalysis; his model portrays personality as a dynamic system directed by three mental structures: the id, the ego, and the super ego. The id is made up of innate biological instincts and urges. The id operates on the pleasure principle. It is self-serving, irrational, impulsive, and totally unconscious. It seeks to freely express pleasure-seeking urges of all kinds. The id acts as a power source for the entire psyche or personality. The ego is sometimes described as the executive because it directs energies supplied by the id. The ego is guided by the reality principle. It is the system of thinking, planning, and problem solving, and deciding. It is in conscious control of the personality and often delays action until it is practical or appropriate. The super ego acts as a judge or censor for the thoughts and actions of the ego. Freud believed that our behavior expresses unconscious forces. He claims that the unconscious holds repress memories and emotions, plus the instinctual drives of the id. He considered sexual impulses to be a primary source of motivation for a person, and that mental activity is essentially unconscious. Freud identified four psychosexual stages, the oral, the anal, the phallic and genital. At each stage, a different part of the body becomes the child’s primary erogenous zone. Each area then serves as the main source of pleasure...

Dr.Jekyll and Mr.Hyde

...Themes Themes are the fundamental and often universal ideas explored in a literary work. The Duality of Human Nature Dr. Jekyll and Mr. Hyde centers upon a conception of humanity as dual in nature, although the theme does not emerge fully until the last chapter, when the complete story of the Jekyll-Hyde relationship is revealed. Therefore, we confront the theory of a dual human nature explicitly only after having witnessed all of the events of the novel, including Hyde’s crimes and his ultimate eclipsing of Jekyll. The text not only posits the duality of human nature as its central theme but forces us to ponder the properties of this duality and to consider each of the novel’s episodes as we weigh various theories. Jekyll asserts that “man is not truly one, but truly two,” and he imagines the human soul as the battleground for an “angel” and a “fiend,” each struggling for mastery. But his potion, which he hoped would separate and purify each element, succeeds only in bringing the dark side into being—Hyde emerges, but he has no angelic counterpart. Once unleashed, Hyde slowly takes over, until Jekyll ceases to exist. If man is half angel and half fiend, one wonders what happens to the “angel” at the end of the novel. Perhaps the angel gives way permanently to Jekyll’s devil. Or perhaps Jekyll is simply mistaken: man is not “truly two” but is first and foremost the primitive creature embodied in Hyde, brought under tentative control by civilization, law, and conscience.
