The Queen Annes Revenge - Blackbeards Pirate Ship

The Queen Anne's Revenge - Blackbeard's Pirate Ship The Queen Annes Revenge was a massive pirate ship commanded by Edward Blackbeard Teach in 1717-18. Originally a French slaving vessel that Blackbeard captured and modified, it was one of the most formidable pirate ships ever, carrying 40 cannons and enough room for plenty of men and loot. The Queen Annes Revenge was capable of fighting off nearly any Navy warship afloat at the time. It sank in 1718, and many believe that Blackbeard scuttled it on purpose. The wreck has been found and has turned up a treasure trove of pirate artifacts. From Concorde to Queen Annes Revenge On November 17, 1717, Blackbeard captured La Concorde, a French slaving vessel. He realized that it would make a perfect pirate ship. It was large yet fast and big enough to mount 40 cannons on board. He renamed it Queen Annes Revenge: the name referred to Anne, Queen of England and Scotland (1665-1714). Many pirates, including Blackbeard, were Jacobites: this meant that they favored the return of the throne of Great Britain from the House of Hanover to the House of Stuart. It had changed hands after Annes death. The Ultimate Pirate Ship Blackbeard preferred to intimidate his victims into surrendering, as fights were costly. For several months in 1717-18, Blackbeard used the Queen Annes Revenge to effectively terrorize shipping in the Atlantic. Between the massive frigate and his own fearsome appearance and reputation, Blackbeards victims rarely put up a fight and handed over their cargoes peacefully.  He plundered the shipping lanes at will. He was even able to blockade the port of Charleston for a week in April of 1718, looting several ships. The town gave him a valuable chest full of medicines to make him go away. The Queen Annes Revenge Sinks In June of 1718, the Queen Annes Revenge hit a sandbar off of North Carolina and had to be abandoned. Blackbeard took the opportunity to make off with all of the loot and a select few of his favorite pirates, leaving the others (including hapless pirate Stede Bonnet) to fend for themselves. Because Blackbeard went legit (sort of) for a little while after that, many thought he scuttled his flagship on purpose. Within a few months, Blackbeard would return to piracy and on November 22, 1718, he was killed by pirate hunters in a pitched battle off of North Carolina. The Wreck of the Queen Anne’s Revenge In 1996, a shipwreck believed to be that of the Queen Annes Revenge was discovered off of North Carolina. For 15 years it was excavated and studied, and in 2011 it was confirmed to be Blackbeards ship. The shipwreck has yielded many interesting artifacts, including weapons, cannons, medical gear and a massive anchor.

The opening of the exhibit drew record crowds, a testament to Blackbeards lasting reputation and popularity. Sources Cordingly, David.

A Study Of Anatomy And Psychology Essay Example for Free

A Study Of Anatomy And Psychology Essay ? The procedure in lifting the leg to climb a stair is a complex one which involves a huge amount of technology inter-transfer between the brain and the eventual skeletal muscle. There is initiation of the movement at the brain which is transmitted via specialized white fibre tracts to the hip flexors via the intermediate spinal cord, involving a very complex mechanism at the cellular level   The initiation of the   process is at the motor cortex (Ms I) of the brain. The primary motor area is located at the precentral gyrus of the frontal lobe. The area controlling the motion of the lower limbs lies towards the superior surface of the brain. Within this area lies the cell body of the primary neuron. These neurons are known as upper motor neurons (UMN). These UMNs receive modulating impulse from the inputs from the cerebellum and the basal ganglia via the extrapyramidal pathways. These tracts modulate the gross movement initiated at the frontal cortex. In turn these areas are modulated by afferent signals from ascending spino cerebellar, and spino-thalamic pathways. The complex the signal initiated at the nucleus of the cell body is transmitted electronically via the axon of the myelinated neuron via the mode of salutatory conduction. The myelin sheath which surrounds the axon of nerves that involve fast transport, breaks at intermediate regions known as Nodes of Ranvier. The electrical impulse moves in   a jumping manner at these nodes nerve transmission as a neural impulse, generated by the formation of a nerve action potential. Like all excitable tissue, nerves maintain a resting membrane potential that is the difference of voltage across the membrane of the neuron. In neurons this value is   – 70 mV. This voltage difference is maintained by the Na/K pump on the membranes. This impulse generated at the axon hillock is transmitted via the depolarizing phase which allows sodium ions ingress into cells via opening of the Na channels. This entry of Na in one portion allows activation of other Na channels, causing depolarization of the adjacent region of the neuron. Subsequently repolarization occurs via the opening of K channels, which restores the membrane potential. Thus this process continues which allows the transmission of impulse. Many such nerves together descend as the descending cortico spinal tract in the pyramidal system, which travels through the midbrain into the spinal cord, decussating at the level of midbrain( 90% of the fibres decussating and forming the lateral spinothalamic tract) and again at the level of spinal cord ( the other 10%, forming the anterior spinothalamic tract) . It is the former which is responsible for the lower limb movements. The cortico-spinal tract travels in the anterior horn cell of the spinal cord till the lumbar level where they synapse with the spinal ventral root neuron (lower motor neuron). A single post-synaptic neuron receives signals from many neurons. At the axon terminal, the propagation of impulses leads to release of neurotransmitters, which are stored in specialized vesicles. The released Ach diffuses into the synaptic cleft and binds with receptors on the post synaptic membrane to produce excitatory post synaptic potentials. This leads to generation and propagation of impulse in nerves which are destined to innervate the neuro-muscular junction. At the neuro-muscular junction, Ach is released, which diffuses into the synovial cleft and binds to receptors in the motor end plate, and triggers a muscle action potential. The released Ach is destroyed by the acetylcholinestrase. At the level of the sarcolemma of the muscles, the muscle AP travels along T-tubules, opening Ca release channels in the sarcoplasmic reticulum. Ca binds to troponin-tropomysin complex, which releases the myosin heads, these then bind to the actin thin filaments, and draws them closer to the M line. Meanwhile bringing the Z disc closer. This leads to muscle fibre contraction. This is a self propagating sequence eventually leading to the contraction of ilio-psoas muscle, which causes the flexion of thigh on the pelvis. Each nerve fibre innervates many musle fibres ( about 150). This is   the motor unit. The greater the number of motor units recruited by the nerve action potential, the greater the force of contraction of the muscles. In the spinal cord, nerve impulse travels along the lumbar plexus (L1-L5) to innervate the iliopsoas ( hip flexion- ilio-inguinal nerve), biceps femors, semitendinosus and semimembranosus ( knee flexion – sciatic nerve), ankle flexors ( EHl, EDL, TA – tibial nerve), leading to the person climbing the step. This excitatory impulse is also associated with the production of inhibitory action potential ( hyperpolarizing impulse) in the antagonists (eg the glutei, which must relax to allow flexors to act. In the event of raising of the upper limb above the head, to lift a book, the impulse travels along the cortico spinal tract till the level of the cervical cord to synapse with the lower motor neurons of the brachial plexus ( C3-T1). From here the nerve impulses travel to shoulder elevators ( supraspinatus, deltoid, trapezius, and latissimus dorsi)- posterior cord ), elbow extensor ( triceps and anconeus – radial nerve) wrist extensor ( ECRL, ECRB – radial nerve), finger flexors ( FDS, FDP – median nerve and the ulnar nerve)   and the intrinsics – ulnar nerve and the median nerve) A Study Of Anatomy And Psychology.

Agree or disagree with Hawking's quotation Essay

Agree or disagree with Hawking's quotation - Essay Example While the importance of talking throughout the history of mankind in general and in the contemporary age in particular cannot be overemphasized, the author is too optimistic and unrealistic about the results talking can produce. Talking can or cannot be effective depending upon the context, participants, topic, and means of communication. For example, the governments of Pakistan and India have conducted dialogues with each other several times, but have never been able to end their differences, and the rift between the two neighbor countries continues, to some extent, even to date. Many wars in the history have reached an end as a result of dialogue between the concerned countries. There is yet a long list of world events in which the dialogues among different countries did not produce any meaningful results. Therefore, it cannot be established that no matter what problem is at hand, all that needs to be done is talking for that. If the author’s argument is supposed to be based on reality, then it is obvious that he is not talking about just any kind of talking. It would take a lot of effective talking to reach a point in time when the wildest hopes and thoughts could be materialized into reality. Effective talking can be defined as the kind of talking that occurs at the right place, in the right environment, at the right time, between the right people, and upon the right subject. But this is an ideal situation which requires a range of events to take place many of which are beyond the control of human beings. Talking is not everything. For example, the first hurdle in the way of developing such a technology is reaching a unanimous decision on its creation because such a technology is likely to harm the world in more ways than benefit it. If anybody could do whatever he/she wanted, then this world would be a mess. There are fair chances that if, ever, such a matter is discussed, there would be so many

The Declaration of Independence and Its Irony for Equality Term Paper

The Declaration of Independence and Its Irony for Equality - Term Paper Example Its primary goal is to discuss how the Declaration departs from its true essence based on the undermined state of the minorities within the society throughout history. For research materials, this paper will deal with the American Political Thought by Kenneth M. Dolbeare and Michael S. Cummings as its primary source of information for the Declaration of Independence. It will also use several internet and magazine articles as other sources of information. Keywords: Thomas Jefferson, the Declaration of Independence, equality and the rights of men, racial discrimination, women, gays, lesbians The Declaration of Independence and its Irony for Equality The Declaration of Independence portrays literal power in the usage of rhetoric devices that clearly stands out throughout the document. Thomas Jefferson, as its writer, had such proficiency beyond doubt that he was a very learned and skilled person. The rhetoric devices used to point at the possibility of a good education and literal skill s well developed throughout the writer’s experiences. As the studies of the Declaration of Independence find attest, the document is perhaps one of the most creatively designed state documents. Distinctively enumerated into exceptional divisions, Jefferson demonstrated some rare writing skills that make it one of the best literal state papers. The Declaration of Independence can be divided into an introduction, a clearly developed preamble, a section describing the indictment of the Crown, denunciation of the American oppressors - the British - and a good conclusion (Dolbeare & Cummings, 2009, pp. 49-52). Any paper passing the test of good writing must at least show such organization. With skill in rhetoric and a steadfast soul for nationalism, Jefferson had created some of the most messianic, heroic and memorable lines contained within the Declaration of Independence. Even down to his choice of words, Jefferson managed to immortalize this document throughout the annals of th e United States. Usage of terms such as â€Å"necessary† creates an impression of the strong need for the Americans to take the proposed action, which is well connected to their human nature. The line, â€Å"One people† can be translated to send a strong message that the Americans and the British were different people brought together politically and breaking the â€Å"political bands† which was a necessity for the survival of the Americans. This choice of words was intended to capture the attention of America’s friends. However, there is one line in the Declaration that gathers much controversy and debate. The usage of the line, "We hold these truths to be self evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among them are Life, Liberty and the Pursuit of Happiness† poses an intention that could have well been deeply thought to bring a diverse interpretation by the Americans, the British and possible allies who could assist the Americans in their quest for independence. This line consists of a group of principles pertaining to human rights that are naturally and rhetorically read and interpreted together.

Margaret Fell Fox Essays -- essays research papers

Margaret Askew Fell Fox In the seventeenth century, a commanding female public minister emerged during the radical religious movement of Quakerism. Margaret Askew Fell Fox was one of the founding members of the Religious Society of Friends, and was popularly known as the "Mother of Quakerism". She has been known less as a minister and more as a founder and provider of financial support then other young women. Throughout this paper I will refer to her as Fell Fox, name she acquired through marriages during her lifetime. Through her struggles and triumphs, radical actions and beliefs, and her desire to worship God, Fell Fox had a significant impact on the world around her. In this essay, I hope to share how Fell Fox’s life, writings, and actions contributed to her radical contribution to life in seventeenth century England. In 1614, Fell Fox was born in Lancashire, England. She was born into the landed gentry, a level of society with both good education and breeding. In her late teens, she married an older man, a highly respected judge, by the name of Thomas Fell. Fell was politically involved in the society and several times was a member of Parliament. During their marriage, Fell inherited a house from his father and he and Margaret lived at the estate. The estate had been named Swarthmoor Hall by Fell’s father. During that time, Fell was often away from home on court circuits. Fell was well known in the region for his hospitality to travelers, and accordingly, the Hall was open to travelers. Fell Fox followed her husband’s desire for hospitality. In June 1652, George Fox came to Swarthmoor while Fell was away on a circuit. (Fox was later credited with being the founder of the Quakers.) When Fell returned home, Fell Fox and their nine children were no longer attending their community Anglican Church. Instead, Fell Fox had deeply involved her family and herself in the â€Å"Principle and Persuasion† that was introduced to her through Fox. We have later learned that the moment Fell Fox met Fox, she changed her religious alliance. According to a analysis of Fell Fox’s works, her conversion from the Anglican Church to Quakerism revealed â€Å"none of the traditional Puritan obsession with self-doubt and self-introspection, while going through a gradual faith-awakening proc... ...aking.

A country boy Essay

Not just my family members and I, every Cambodian citizen is the victim of genocide, the act which took the lives of around two million Cambodian citizens. One can say that this is the curse that all Cambodians were to experience while the others might say that it is our sin or karma. The war ended, and my family had to start from the scratch all over again. I did not really know how hard my grandparents had to go through to raise four children, but I experienced growing up living in a one-storey flat which was the shelter of at least ten family members. Unlike the other kids, I rarely saw my parents since my father had to work far away from home, and my mother was still pursuing her Bachelor Degree in Biology. I spent most of my childhood with my grandparents. My grandmother would always tie me behind her back to the hospital where she is still working as a retired doctor while my grandfather is a retired administrative staff of the same hospital, and was a former Lon Nol’s air force. I can still remember how I envied some of my childhood friends whom I called â€Å"Rich Kids†. During my very first day at school, my classmates were showing off their new bags, yet I only had a black plastic bag to store my books and pencils. The other kids were mocking that I did not even have a bag to carry my books to school. I was a quiet kid, and I chose to remain silent. I came back home, and told my grandmother that I wanted a bag. It took her around a week or two to buy me a yellow used bag which cost around 1000 Riels or less. Though it was a used bag, I hugged my bag with joy. I was a kid from the province, and I did not have a chance to go to expensive language schools like some other kids. Due to financial constraint, my parents had to send me to the language schools nearby. I never did well in English class. I was the worst student in my English class. Luckily, my parents were better-off, and they sent me to an international school. It is the place that changed my life. From a language student who never did well in class, I have now become a teacher of English. From a student who copied the whole reading text to submit to the teacher as a writing assignment, and got zero for plagiarizing, I have now won four national writing awards. Again, March and April this year have marked another turning point of the life of this country kid. I was slapping my face to see whether it was a dream or reality. I used to be rejected by the 26th ranking university in Asia, yet I got admitted and have been given a full scholarship to do a Master Degree at the second- best university in Asia which is one among the top universities in the world, and at the same time, I was also among the citizens of five Southeast Asian nations to be offered a full scholarship to pursue a Master Degree at one of the wealthiest universities in Europe. I failed once or twice, and it does not mean that I would always fail. I believe that life is full of possibilities. Life tests us to see how patient and how determined we are. Life does not kill us, but it teaches us. With hope and commitment, I believe that a person can make positive change to his or herself and to the society. â€Å"I like the night. Without the dark, we’d never see the stars.† ― Stephenie Meyer, Twilight

How Did The American Revolution Affect The French Revolution

How did the American revolution affect the French revolution? The French revolution took place after, and was deeply affected by the American revolution. From 1765 to 1783 the American revolution involved the colonists and Great Britain in a civil war. The colonists left England planning to make riches, find religious freedom, and leave persecution. Eventually thirteen colonies were formed along the Atlantic coast of North America. Later problems involving new acts led to the wanting for independence, and in 1783 the Treaty of Paris was signed, finalizing American independence. Six years later began the French revolution, from 1789 to 1799. The French revolution was a civil war between the three French Estates. After helping the†¦show more content†¦Later Parliament passed the Tea act, British companies could ship tea without having to pay tax, threatening to put American merchants out of business. To keep the angry colonists under control the Intolerable Acts were passed, shutting down the Boston Harbor and keeping the region under military control. This sparked the first battle of the American revolution, after the First Continental Congress. During the 1700’s the French were divided into a hierarchy with three estates. The First Estate was made up of church officials, and the Second Estate was made up of nobles. The nobles and Catholic clergy lived high lives, they enjoyed privileges such as education, not having to pay taxes, the right to vote, along with high social and occupational standings. Then there was the Third Estate which made up about 98% of the powerful European country. At the top of the Third Estate were the bourgeoisies, people like merchants and bankers, then there were servants and artisans, at the very bottom were peasants. Although they paid taxes they, like the American colonists, had no representation in government, and endured hard labor with little education. â€Å"This is not of much consequence, for the people, ins tead of reading their memoirs, are not able to read at all...In the agricultural conversations we have had on the journey from Orleans, I have not found one person who seemedShow MoreRelatedThe French Revolution And The American Revolution1395 Words   |  6 PagesHonors English 29 September 2014 The French Revolution Some do not know what the real cause of the French Revolution was.
