So what killed the dinosaurs? Without having any background education in science it is hard for the general public to comprehend such matters and they rely on the knowledge of the scientists in this field. Although there has been much research on the subject nobody has come up with a conclusive answer. And we are left to read the countless articles, all having their own opinions as to the mass extinction. One such theory is that a shift in the solar system could have caused the mass destruction. According to an article published in Nature magazine,
“A bizarre wobble 65 million years ago, perturbing the orbits of Mars, Earth and Mercury, may have caused the demise of the dinosaurs, new models of the Solar System suggest.”
The article suggests that an upset could have “disrupted the trajectories of asteroids-normally safely confined to asteroid belts-sending one or more into the Earth.” This is an easy enough idea for the general public to understand yet it is not stated if they know what caused the upset in the first place. And this is where we depend on the researchers to come up with a way of finding this out. They designed a model that would mimic the Solar System 100 million years ago, “based on natural variations in planetary orbits, their proximity to the Sun and their gravitational effects on one another.”
What they did find was fluctuations in the model dating back 65 million years ago right when the asteroid supposedly hit. Even though it sounds like good solid evidence a lot of scientists are still not sold on the idea and need more convincing.
In another article it is suggested that had a meteorite, large enough to cause mass extinction, hit the earth there would have been widespread wildfires wiping out eve...

The possibility if a meteor strike as the cause of extinctions is discarded, something that most specialists agree on. There is no evidence of any meteor crater big enough or recent enough to be accountable for it; there are no “elements that are common extraterrestrially but less so on Earth, such as iridium, and no sign of a tsunami or other phenomena following the impact.” The extinctions where also very selective and occurred over a very long period of time. If a “one shot” catastrophe had been the cause it would have affected all species at the same time and in similar
...ories of why dinosaurs went extinct abound, and as there is no theory yet to be truly confirmed as the “right one”, my theory of dinosaur cannibalism is also purely anecdotal. The discovery of the cannibalistic Majungatholus atopus in Madagascar is an important scientific find because it confirms a long-standing theory of cannibalism among certain carnivorous dinosaurs. Behavioral patterns of extinct animals are difficult to establish; however, these bones give authentication to previous unfounded beliefs about the ancient feeding practices of some dinosaurs.
The late nineteenth century Irish novelist, Bram Stoker is most famous for creating Dracula, one of the most popular and well-known vampire stories ever written. Dracula is a gothic, “horror novel about a vampire named Count Dracula who is looking to move from his native country of Transylvania to England” (Shmoop Editorial Team). Unbeknownst of Dracula’s plans, Jonathan Harker, a young English lawyer, traveled to Castle Dracula to help the count with his plans and talk to him about all his options. At first Jonathan was surprised by the Count’s knowledge, politeness, and overall hospitality. However, the longer Jonathan remained in the castle the more uneasy and suspicious he became as he began to realize just how strange and different Dracula was. As the story unfolded, Jonathan realized he is not just a guest, but a prisoner as well. The horror in the novel not only focuses on the “vampiric nature” (Soyokaze), but also on the fear and threat of female sexual expression and aggression in such a conservative Victorian society.
However, there are still many factors in the evidence collecting process that make it difficult to determine the actual events, let alone the sequence of them. For instance, at the end of the Permian, giant volcanic eruptions occurred in Siberia, spewing out some 2 million km3 of basalt lava, and covering 1.6 million km2 of eastern Russia to a depth of 400-3000mteres, equivalent to the area of the European Community. Consequently, with increasingly precise dating, the Siberian “Trap” (areas which are composed of basalt, a dark-colored igneous rock which is generally not erupted explosively from classic conical volcanoes, but usually emerges more slowly from the long fissures in the ground) have switched from having only a minor role in the Permian crisis to being the most probable cause of the whole catastrophe. Some scientists have even suggested recently that the massive flood basalts were actually themselves caused by a giant extraterrestrial impact, which tore deep into the continental crust of that part of present-day Siberia. So this is yet another example the evolutionary and
Bram Stoker wrote many novels in his life time; he was a brilliant author and could have in fact possibly imagined how significant an impact his novels could have effected literature throughout the ages and more importantly today. Considering Stoker focused on how the past could affect the present and incorporated that ideology into many of his novels including Dracula. Dracula has come to be one of the most well-known pieces of literature in the world. Vampires are everywhere, in many fiction novels and all over TV, which garnered their inspiration from Stoker’s novel Dracula. Although this novel was controversial at the time it was published during the Victorian era, it has accumulated success and has continued to survive and thrive throughout the nearly century and a half since it has been published. It has attributed much to the literary world. This epistolary novel put a spot light on the mysterious, sexuality and mystery that readers today adore.
There has been a debate about what happened to the dinosaurs since they were discovered. There are many thoughts of what happened to the dinosaurs, the two main theories behind the extinction are scientific and religious. Proof for both theories do exist and debates between scientists are still going on to which one really happened. It is a mystery as much for Evolutionists as it is for Creationists about the extinction of the dinosaurs. The fossil record of dinosaurs was poorly know for a long period of time. During this time period was when the dinosaurs were thought to have gone extinct. The scientific reason for their extinction was that there was a giant asteroid that caused chain reaction and wiped out the dinosaurs. Some scientists say the dinosaur’s extinction came quickly. Evolutionists say the dinosaurs went extinct 65 million years ago. Creationists say that the dinosaurs weren’t able to survive the Earth after the flood. Both of the theories have supporting evidence and that is why there is an ongoing debate over what really happened to the dinosaurs.

On July 27, 1890, van Gogh woke up to paint in a wheat field as he usually did, but this time shot himself in the chest though the bullet did not kill him. He was later found in his room bleeding out. Two days later, on July 27, Vincent van Gogh died in the arms of his brother, His last words being, “La tristesse durera toujours" which translates to, “The sadness will last forever” His brother, who was already suffering from syphilis, died six months later from the grief of losing his
Count Dracula is written into vampire history and lasts to this day. He is now unarguably the most worlds’ most famous vampire. Count Dracula is the lasting legacy that Bram Stoker leaves on this Earth. Even to this day, he is never able to hide from the aura of vampirism and awe that he is leaving behind today. In the dawn of the vampire age, Bram Stoker’s Dracula has given a spark to the fire of vampire culture that has been ever growing into the 21st century.
Throughout Earth’s history there have been many changes. These changes have consisted of temperature fluctuations, atmospheric differentiations, extinctions of various plant and animal life, etc. Over time everything seems to have evolved in some way form or fashion. However, the Permian Era extinction was different from all the rest. This extinction affected every form of life, but especially the marine life. Researchers have stated that 93-97% of all Earths species went extinct during this period of time. This essay will explain how a once blossoming progressive era turned into Earths most catastrophic event.
“Sex, Drugs, Disasters, and the Extinction of Dinosaurs” is written by Stephen Jay Gould, professor of geology and zoology at Harvard. This essay is one of more than a hundred articles on evolution, zoology, and paleontology published by Gould in national magazines and journals. It tells about scientific proposals for the extinction of dinosaurs – a confusing but an exciting problem that humanity tries to solve. By analyzing and describing each of the claims for the reptiles’ demise – sex, drugs, and disasters – Gould differentiates bad science from good science and explains what makes some theories silly speculations, while the other, a testable hypothesis.
The most famous vampire is Dracula, the main character in the book Dracula written by Bram Stoker in 1897. It is said that Stoker was inspired by the Transylvanian Prince VladIII, also known as Vlad Dracula, but other than the name there are not many similarities that prove he was Stoker’s role model. Before Stoker shocked the...
It is precisely the point that Hollywood distorts and corrupts serious literature for the entertainment pleasures of a mass audience. In the task of comparing and contrasting the novel of "Dracula" to film extracts of "Bram Stoker’s Dracula", values, meaning and context discovered lie between discrepancy and similarity. The change from differing mediums, novel and film, reveal characteristics and possibilities of narratives. Through the advancement of technology, modern writers have gained a cinematic approach to their writing. However Dracula, written in 1987 by Abraham Stoker, where the introduction of technology was gradual, forging inventions such as the typewriter and phonograph, made reference to in the novel, had no anticipation of what technology would have an effect on such writings. With society’s fascination with the supernatural, and love of technology, Dracula’s many adaptations, film, stage, have ensured its survival through the passage of time.
At the age of sixteen, Van Gogh went to go work with his Uncle Vincent, whom he was named after, as an art dealer at the Goupil and Co. This job had branches not only in Europe, but America also. Vincent was assigned the branch in London. There he got his first rejection in love. He fell in love with the daughter of his landlady. Van Gogh thought her feelings would be mutual, though she was not attracted to him. In fact, she was disgusted by him. She was engaged to be married, anyway. Because he was so hurt from this rejection, he took it out on his career. He told the costumers they were buying useless junk and insulted them for that. Van Gogh had to go to Paris and only his uncle's influence allowed him a second chance with the firm. His harsh behavior toward the costumers continued. In 1876, the Goupil's managers had to let him go.
