Abstract
This paper examines the positive and negative nature of electricity, which was first identified by Benjamin Franklin. This paper details the basics of lightning, which is a natural occurrence, generated through the two interactive processes of tribo-electricity and electrostatic induction. This paper delves into how thunder clouds are formed by ice and water. This paper also contains an illustration, detailing the origins of lightning, as well as a table listing the dielectric constants of various insulators, relevant to this particular topic.
From the Paper
"In a thunder cloud, the two dissimilar materials are ice and liquid water. Most thunderclouds' bottoms are at about 5km above Earth's surface, where it is usually sufficiently cold to freeze any liquid water. Powerful winds circulate up and down the interior of a thunderstorm, bearing up small drops of freezing water which collide with descending hail stones. Even though these two objects are made from water, the fact that one is large and solidly frozen while one is small and only partially frozen means that they occupy different positions on the tribolectric scale. The hail stones tend to become negatively charged and the smaller particles positively so. The negative charge accumulates at the base of the thunderstorm, and the positive at its top. In essence, thunderstorms act like immense Van de Graaff generators."

Abstract
This paper explains that Mark Twain's "Mrs. McWilliams and the Lightning" apparently takes place in a carriage of a train and is told by a certain Mr. McWilliams, who is telling stories to the listener, but in fact is re-telling and transmitting Mr. McWilliams' words. The author points out that the humor in the story is (1) a very extensive and well-developed dialogue, which is almost never interrupted, (2) is the voice of the narrator who seems to be very impartial in spite of the fact that he is one of the main participants of the story and (2) the style and language of the whole piece are very important for the creation and development of the comic effect because they add heightened color to the absurdity of the situation. The paper relates that the story has a pace, which resembles very much a train: At the beginning, it starts slowly, with Mr McWilliams presenting his tale, then it accelerates and continues in a quick pace for a while with accelerating dialogues along the way and, finally, when the train comes to a stop, the story comes to a stop on its turn.
From the Paper
"The story begins with Mr. Williams giving his listener (or listeners) some personal thoughts on the subject. After comparing the fear of lightning to a dangerous disease or a handicap and saying that it is so for human beings he goes on to put on the same scale both dogs and human beings: "It is mostly confined to women; but now and then you find it in a little dog, and sometimes in a man." This effectively sets the humorous tone for the whole tale which truly starts with Mr. McWilliams waking up because Mrs. McWilliams calls him out of the boot-closet where she has hidden herself. Then, we have a series of dialogues between the two, Mrs. McWilliams giving orders to her husband about how to save himself from lightning while he tries to reason her. The second part of the story contains two passages in German which are used by Mrs. McWilliams to persuade her husband that he has to protect himself from lightning even inside the house."

Abstract
This research paper focuses on the language of Herman Melville?s "The Lightning-Rod Man". The author examines diction, characterization, and description, and how Melville uses these aspects to portray the theme and religious symbolism of the story. Also includes short comparison to John Milton?s "Paradise Regained".
From the Paper
"Herman Melville?s short story, ?The Lightning-Rod Man,? first appeared in Putnam?s Monthly Magazine in August of 1854 and was later published in Melville?s The Piazza Tales in 1856 (Verdier, 273). It seems all critics have a different opinion of the story. One anonymous critic said,? ?The Lightning-Rod Man??a story which excited great attention when originally published in Putnam?s Monthly? (Parker, 83). One the other hand, another anonymous critic said, ? ?The Lightning-Rod Man? is a very flat recital which we should never have suspected Melville of producing, had it not been put forth under the sanction of his name? (Parker, 81). Critics also differ in what they think is the theme of the story, but most will agree that Melville creates religious symbolism through his diction and characterization. Verdier says, ?the tale may be seen as a confrontation between Good and Evil? (274), which the story, on an emblematic level, most definitely is. Through description and diction, the narrator is understood as a follower of God, someone who believes in The Almighty watching over him. On the other hand, the lightning-rod man is seen as a negative character, someone who only has faith in the product he?s peddling. Symbolically, the lightning-rod man is representative of Satan himself. "

Abstract
Lightning is a natural phenomenon that is dramatic, often beautiful, and yet deadly and dangerous at the same time. A bolt of lightning involves the rapid discharge of a massive amount of electrical energy producing both the bright flash of light and the sound of thunder
From the Paper
"Lightning is a natural phenomenon that is dramatic, often beautiful, and yet deadly and dangerous at the same time. A bolt of lightning involves the rapid discharge of a massive amount of electrical energy producing both the bright flash of light and the sound of thunder. There are a number of different kinds of lightning produced by different conditions, and new information on lightning is discovered all the time. By its nature, lightning is an ephemeral phenomenon, making it difficult to study under all conditions and explaining why new types of lightning have been found as man makes his way higher and more often into different regions of the upper atmosphere. Lightning is an extremely common natural phenomenon. Since Benjamin Franklin demonstrated the electrical nature of the lightning bolt, lightning has been subjected to many scientific studies."

Abstract
This paper presents in chronological order the study of lightning and how as new ideas would come about and be proven, other inventors would use that idea and take it into a new direction.
From the Paper
"Lightning is a form of static electricity. When it is raining, raindrops can acquire extra electrons. These negatively charged raindrops seek out the positively charged ground. When these two charges connect, current flows through randomly placed areas of charged particles. This is what lightning is, and what gives it the jagged pattern (see diagram). Lightning has been on Earth longer than people have. Still we don?t know everything about it. We do know that lightning can take a variety of forms. The most common are forked, streak, ribbon, or bead lightning. All of these types are essentially the same with variations on atmospheric conditions. There is one type called ball lightning, but very little is known about this type. It is also known that lightning will travel from cloud to cloud, cloud to ground, and ground to cloud. Early studies done to find that lightning is electricity paved the way for several other important findings about electricity and how it behaves."

"In some substances, particularly metals, negatively charged particles (electrons) can move easily. Such substances are called electrical conductors. Other substances, in which electrons do not move freely, are called electrical insulators. There is another group of substances which are neither good conductors nor good insulators but which have become increasingly important in the last 50 years; these are called semiconductors."

Abstract
The strengths and weakness of various theories including extremely low frequency (ELF) electromagnetic radiation waves and quantum theory as it applies to psi are discussed. Also examined are the problems of scientific paradigm shifts and the possibility that the statistical evidence for psi activity is an "anomaly" in our current paradigm and a precursor to a paradigm shift.
From the Paper
"Parapsychology occupies a unique position within the scientific realm. The results of the field are often considered invalid, fraudulent, or insignificant. Psi is often thought to be inconsistent with the current knowledge of physics. Despite the large body of statistical evidence for anomalous cognition, psi will not be widely accepted until a solid, testable physical theory is developed. Although the uncertainties and seemingly illogical consequences of quantum theory seem promising for the development of this sort of theory, as yet none exists."

Abstract
This paper explains that, throughout history, investors have been caught off-guard by the bursting of one speculative bubble after another. The author believes that investors should be in the market for the long haul to reduce its volatility. The paper suggests the use of the stop-loss orders on every stock purchase, which stop a stock's free fall when things go wrong; the IBD philosophy is to set the stop at 8% below the purchase price.
From the Paper
"Like an overzealous clown blowing up balloons, eventually those balloons will not hold any additional helium air and they, well, ?BURST.? We should learn financial history for the sake of avoiding making the same idiotic mistakes from other generations. But, our human nature continues to allow great financial and social losses to occur because speculative bubble investing continues. Some examples of speculative bubbles have colorful names like the Tulip-Bulb craze, the south sea bubble, the Florida real estate craze, the nifty-fifty era and, yes, The Crash of 1987."

Abstract
Our ability to remember sets of verbal and visual landmarks and to conceive their relationship with us, depends on our orientation and spatial cognition. This paper deals with memory mechanisms for representing visualizations of different phenomena from our external environment. This paper illustrates how subjective aspects are represented in memory and how characteristics of these affect response quality. This experiment also checks memory performance for the questioning in Urdu.
From the Paper
"Memory is divided into semantic, episodic and procedural memory. The questionnaire tests the major aspects relating to episodic and semantic memory. When testing for these, one must also be testing whether memory is reconstructive or reproductive. Reconstructive memory is recalled based on stimuli that have post event encoding and storage. This questionnaire has tested exactly this.
Perception is an active process. It is carried out through the provision of data through stimuli and the organization of stimuli through one?s experience. One?s perception is guided through expectation of events."

Abstract
This paper is a quantitative study of the phenomena of connectivity that uses a sample population of 425 displaced women treated in Bogota, Colombia, to test the hypothesis. The author used a formal questionnaire with two main scales to measure the degree of connectivity among these women against a background of emotional and psychological well-being. The paper reports that this thesis has found evidence for 1) a biological basis for connectivity, 2) psychological effects on connectivity, and 3) environmental effects on connectivity. These findings are extremely important because such a study has not previously been undertaken and because these results add weight to the body of literature that suggests trauma can lead to anti-social, deviant behavior arising from a lack of connectivity.

"Attachment theory developed out of this early work of Bowlby?s, combined with his growing awareness of evidence emerging from developmental biology and the new science of ethnology. Lorenz?s work with imprinting in birds and Harlow?s work with monkeys showed that affectional bonds could develop unrelated to the satisfaction of hunger needs. Bowlby?s (1958, 1969) insights led him to conclude from this that humans needed social interaction that was satisfied by the caregiver being close by and available for support when needed, This was in contrast to the traditional psychoanalytic theory of dependency, where affectional bonds were thought to develop secondarily to the primary drives for food and sex. As attachment behavior had been found to occur in most species of mammals, he suggested that there was a ?primary attachment relationship? that developed during the first nine months of life whose evolutionary function was to protect from predators "

"Thunderstorms are impressive and terrifying natural phenomena. Rattling the earth with sharp, explosive sounds of thunder, and lighting up the sky with electric bolts of lightning. As Mark Twain once said, "Thunder is good, thunder is impressive, but it's lightning that does the work."
Thunderstorms are defined in terms of their electrical manifestations which in fact are a product of the storm itself. The development of a thunderstorm is a continuous process but there are three recognizable stages through which the storm goes ((Hidore).
The first stage is the cumulus stage. During this stage cumulus clouds become larger and taller. There is a general updraft throughout the cloud formation and condensation in the form of water particles. The updrafts are strongest toward the (...)"

A Study of Unidentified Flying Objects, 2005.
This paper examines the phenomena of unidentified flying objects.

Abstract
In this article, the writer notes that one of the more curious unexplained phenomena of our age is the continuous sightings of unidentified flying objects. The writer points out that unidentified flying objects (UFOs) have been sighted since ancient times and are still sighted each day. Some believe that the UFO phenomenon has something to do with everything from the pyramids to the beginning of life on this planet. Others insist that the entire idea is ludicrous and every sighting can be explained as either a hoax or as a result of "natural" causes. The writer discusses what actually classifies as a UFO and notes that one way of looking at this is to classify UFOs as anything that takes flight that is unidentifiable at the time. The writer maintains that the problem remains that numerous sightings do not fall into these categories and remain in the realm of the unexplained.
From the Paper
"Like many in the private sector, the government sightings are far from all being the same. On February 15th, 1965, a United States Air Force captain stared upward into the sky and, to his amazement, saw three enormous, oval-shaped objects. In 1953, while running the initial tests on a new tracking device, US Air Force operators were astonished to pick up a gigantic object orbiting near the equator. Some type of huge, unknown object was circling the Earth some six hundred miles out. Another, this sighting on May 5th, 1954, depicts a military that is not sure what they are dealing with ..."

Abstract
This paper states that, to date, parapsychology research has only been able to demonstrate the likelihood of the ability to ?read minds?. The author reviews the SCAI experiments but believes that science has not been able to explain clearly and definitively the phenomena. He concludes that currently science believes the probability of people being able to read minds is low though evidence in the future may indicate otherwise.
From the Paper
"Recent premises for the above claim by parapsychologists are the results of the ganzfeld, the random-number generator, and the famous SRI and SAIC experiments. Prima facie, it would appear that there is a great deal of empirical evidence to indicate that mind reading can and does happen. However, a closer look will reveal that all the cited examples of scientifically approached experiments suffered from certain limitations. The SAIC experiments on anomalous mental phenomena have been acknowledged by a large body of respected scientists to be methodologically and statistically superior to the earlier SRI research as well as to previous parapsychological studies, since they avoided all the major flaws such as non-independent trials and the problems of multiple statistical testing that was characteristic of much of the previous work."
