was advanced in 1957 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

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
Behavior Consultation Theory For this project the behavioral consultation theory (BC) will guide the process of the consultation. The behavioral theory has evolved over the years. At first, the behavior concept started with Watson (1930). He studied only what could be directly observed and measured-behaviors. Then Bandura (1977), the neobehaviorist, he developed the social cognitive theory that has been used to develop some BC techniques. Following, Bergan, (1977) developed the behavior-operant
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
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
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
“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 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
The plague of Athens The Athenian plague was an epidemic that began in the summer of 430 B.C. in Athens—a year after the Peloponnesian war in 431 B.C. It was supposed that the plague was a result of excess number of Athenians within the city walls also known as the long walls—a military strategy by Pericles which consisted of building walls that connected the city to its port . The surplus of Athenians led to a shortage of food, water, an absence of sewage systems, and other important factors were
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
Championship Series (BCS). College football over the years has picked the national champion in the wrong manner by using a flawed system. The BCS was chosen to help with the National Championship game and unfortunately not a popular choice among fans. Fans have argued that the BCS is unjust and a playoff system would be the best scenario to help decide who the real national champion really is. The BCS has their own advocates to keep it around and not use the playoffs. To keep using the BCS would gravely
This paper covers a personal view concerning theories of counseling. Personal beliefs about human nature are also discussed and a balance of life and self-awareness is identified as being one of the most important aspects to human change. It is identified that change only occurs when an individuals’ conditions are altered. Conditions are unable to change without a person first obtaining insight and taking action towards making change happen. Personal theoretical orientation is also discussed. Establishing
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
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
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
