New Superconductors: Advances, Issues, Limitations Report by Amber Taylor CHME 5699 Dr. Laura Lewis Final Report 23 April 2014 Executive Summary One of the most exciting and magical phenomena observed today in science is the levitation of superconductors in the presence of a magnetic field. While entertaining, this effect is also extremely useful and could combat one of the largest issues facing the world today: how can we continue to transport goods and people without burning fossil fuels
Before Kamerlign Onnes, in 1908, was able to liquefy helium and bring its temperature down to about 1K, it had been known that the resistance of a metal falls when cooled below room temperature. However, it was not known what value the resistance would approach if the temperature was reduced towards 0K until Onnes, while experimenting with platinum, discovered that, its resistance fell when cooled to a very low value that depended on the metal’s purity. As the temperature of mercury was reduced
doesn’t look bright for them. Egypt was one of the first and largest countries beginning in 4000 BC when the Lower and Upper kingdoms merged to create one big country. It was conquered multiple times before becoming its own country again. In 525 BC, Egypt was conquered by Persia and was led under their rule until 332 BC. Alexander the Great took over Egypt from Persia in 332 BC and ruled until 30 BC After Cleopatra killed herself at the age of 39, the Byzantine Province ruled Egypt. Napoleon ruled
My choice for this particular tourism destination is an island off of the coast of the huge Canadian metropolis of Vancouver called Vancouver Island. This particular island was ranked second in 2009 on Condé Nast Traveler’s Reader’s Choice Awards “Top Islands of North America;” Vancouver Island is a relatively large island with a population of 759,366 inhabitants. It is home to British Columbia’s capital city, otherwise known as Victoria. The island is separated from the mainland by four different
by American physicists John Bardeen, Leon Cooper, and John Schrieffer. Their Theories of Superconductivity became know as the BCS theory (which came from each mans last name) and won them a Nobel prize in 1972. The BCS theory explained superconductivity at temperatures close to absolute zero. However, at higher temperatures and with different superconductor systems, the BCS theory has consequently became insufficient to fully explain electron behavior. The Type 1 category of superconductors is basically
A "Golden Age" for Athens? The 5th century BCE was a period of great development in Ancient Greece, and specifically in Athens. The development of so many cultural achievements within Athens and the Athenian Empire has led scholars to deem this period a "Golden Age." It is true that his period had many achievements, but in the light of the Athenians treatment of women, metics (non-Athenians living in Athens), and slaves it is given to question whether or not the period can truly be called "Golden
Defining the Great Dionysia The Great Dionysia, celebrated in the Greek month of Elaphebolion, was seen by all Athenians as an important religious festival. It became a vital celebration in the Athenian calendar and gained international status; many ‘foreign aliens’ travelled from other Attic states to witness the performances. Athenians saw it as a religious festival with rituals that needed to be followed, however, prominent politicians were able to use this to their advantage. Some
“is one of the most revered figures in Greek history” because of his wisdom, integrity and political skills writes John Lewis (2008, p.1). Known as the lawgiver of Athens, he created the first constitution “when he was chosen as chief archon in 594 BC” explains William George Forrest (1996, p.30). In the same year, Solon initiated a series of laws and reforms that had a lasting impact on Athenian society. One particular law that Solon reformed, made him very favourable among the community. He let
The first year of fighting between Athens and Sparta is drawing to a close. As is customary during war, Athens holds a public funeral to both celebrate and mourn their fallen soldiers. Such ceremonies typically featured an oration given by a respected Athenian – with this year’s coming from renowned statesmen Pericles. Previous orations had focused on celebrating the Athenian military by recounting their trials and accomplishments. Pericles decided to depart from this convention, believing it was
In 490 B.C, King Darius made his final push towards Athens. The Athenians were waiting for the Persians to arrive, ready to fight. It seemed crazy for Athens to retaliate against the Persians at this point. Historians still wonder why the Athenians and their 10,000 soldiers stood up to the Persians and their 25,000 soldiers, but this is because of their gallantry. The Athenians valued pride over cowardice.. Athenian men, since childhood, were inspired by tales of the Odyssey, Iliad, etc, and were
In my past experience with learning writing, I can group the ways I have been taught into three categories. I have learned by teaching myself how to write, have learned in an academic setting, and have learned through hands-on experience in a professional setting. The first time that I attempted to write, as I know understand it, was for the purpose of writing a book. At the time, I was only ten years old, so it wound up being a series of short stories consisting of no more than a few pages each
In the Hellenic era from 500 to 338 BCE, the Greeks had many major values. These values include Greek mythology, social roles, war, agriculture, and government. Some of the values are still present today. Greek mythology is still prevalent in the modern Greek society and western society because it is still studied today. The Greeks’ view on social roles is one of the ideas that are not shared in modern society but were widespread in past culture. The Greek agricultural and political values are used
The Archaic period of ancient Greece gave rise to the formation of a Greek identity and provided the foundation for later period’s belief in Greek superiority over her neighbors. In Athens the Solonian reforms, Peisistratid tyranny, and the reforms of Kleisthenes all led to the rise of a democratic Athens (Bintliff 2012; 237, 240). During this time, the Persian empire expanded into Ionia and made excursions into Thrace, the region to the north-east of Greece. During the Ionian revolt against Persia
Persian Empire, and Rome before arriving in Athens . The disease attacked the population of Piraeus and then travelled to Athens where the death tolls were greater. The plague came back in 429 were it claimed the most lives, and later on in the winter of 427/426 B.C were it claimed more lives. From man to woman, the rich and the poor, and the elderly and the young, everyone in the Athenian population was affected by the disease. As it will become evident, the Plague of Athens devastated Athens and which
Thucydides’ interpretation of Pericles’ Funeral Oration is a significant text of the Classical World, delivered by Pericles during 5th Century Greece and the Age of Pericles. It is intended as an account of the soldiers lost during the Peloponnesian War, however it is a statement that expresses the myth and ideals of Athens, all of which are relevant to 5th century Athens. It functions as a model for future societies and portrays the unique image and characteristics of Athens. Within the oration
Pericles, the leader of the Athenians had presented this oration about those people, who had first fallen in battle. It is part of their law and show the respect of honor to those who had lost friends and families. The purpose of Pericles’s speech was for the ancestors the supervisors, who died for their country and lands. This famous oration was from the early days of Peloponnesian war. The speech was for every Athenian and any others who wished to attend. Athens was one of the oldest first city
The late 5th, early 4th centuries, in Athens were an eventful and emotional time for civilians. Between wars and the political debates of the time, civilians were fearful and anxious over the uncertainty of their government. To their advantage, they had games and other forms of entertainment, such as western theater to distract them from the outside world. Aristophanes was one of many playwrights to write comedy and satire plays, specifically Clouds and Women at the Thesmophoria are said to be the
During the Classical Age of Greece, two powerful city-states emerged, each governed by a different system. Athens was run by democracy, whereas, Sparta, a military state, was governed by oligarchy. Athens' democracy served its people better. Since all had a say in the government and everyone was included in a state was ruled by many. In Sparta, the state was controlled by a select few, kings and ephors, who had absolute power. In Athens plenty of time was spent on architecture, to ensure that Athens
The Delian League was an incredibly unique political system that would dominate the Greek world in the fifth century B.C.E. This dominance, maintained through the sheer military might of the Athenian navy, led to an unprecedented strengthening of the Aegean economy and Greek culture as a whole. Economic prosperity in Athens led to the strengthening of the Athenian democracy. Unfortunately, the whims of the Athenian Demos and demagoguery led to a massive weakness in the political system. Within the
The Trinovantes’ earliest interaction with Rome occurs during Julius Caesar’s British campaign in 55 B.C. During his campaign, Caesar’s protection is requested by Mandubracius, the young son of the deceased Trinovantian king, Imanuentius. In his account, Caesar brings the Trinovantes under his protection—only after they agree to his terms—and describes the tribe as “almost the most powerful state of those parts” (Caesar 5.20, De Bello Gallico). It can be inferred from this passage that the Trinovantes
