- 2241: Cryogenics and the Future
- ... in 1986, J Gregore Bednorz and K. Alex Muller discovered that an oxide of lanthanum, barium, and copper becomes superconductive at 30 K. This discovery shocked the world and stimulated scientists to find even more "High- Temperature Superconductors". After this discovery, in 1987, scientists at the University of Houston and the University of Alabama discovered YBCO, a compound with a Tc of 95 K. This discovery made superconductivity possible above the boiling point of liquid Nitrogen, so now the relatively cheap, liquid nitrogen could replace the high priced liquid helium required for cryogenic experiments. To date the highest reported Tc is 125 K, which belongs to a compund made of Thallium, Barium, Calcium, Copper, and Oxygen. Now, with the availability of high-temperature superconductors, all the sciences including, cryogenics have made extraordinary advances. Some applications are demonstrated by magnetically levitated trains, energy storage, motors, and Zero-Loss Transmission Lines. Also, superconducting electromagnets are used in Particle ...

- ... earthly father), a mentor (a coach or teacher), or her Heavenly Father for support. He tells her to Spread your arms wide, to open herself to all she can be; to set her goals as high as the gulls fly; as high as her abilities will allow her to attain. He advises her to allow others to help her, but to always make certain the goals she sets are pure, and the people she puts her trust ... warns her that goals set too low will not prepare her for the future when she must be out on her own. Then, he assures her that when she does these things; sets her goals high, allows others to help prepare her for the future, then she can use that base for support as she goes through life. This poem is speaking to a beginner. The beginner could be any ...
- 2243: Education Of The Middle Ages
- ... were the Knights who had learn how to fight with various weapons so that they could fight for their king. The common people, however, had no way of being educated other than going a monastic school. However, if they did this, they had to donate their property to the church. The people who went to this school later become monks or nuns. They had to follow three important laws: chastity, obedience, and the law or the lord if not followed they would be thrown out of the monastery. Most monasteries had a ... a place to stay (Monasteries 499-501). Cathedral schools were there to train higher-member of the Church in their professional duties as ministers of the Christian people. The bishop in whose Cathedral complex the school was located needed a group of trained priests to administer the various needs dioceses. The Cathedral school largely emphasized practical skills, effective reading, singing, and knowledge of Church Law, public speaking and the administration ...
- 2244: Our Declining Education System
- ... the problems they are faced with and still offer the best possible education to our youth. The use of drugs in the general population has become a very serious problem in society and within the school system. There are two aspects to drug use that teachers are having to deal with now. The first is in trying to teach the new generation of crack babies that are now entering the schools. These students have extremely low attention spans and can be very disruptive in class. Early intervention programs designed to target these children and focus on behavior management within the school setting have been effective in preparing these students for school. Educators have also identified drug use among students as one of the most significant problems that our schools face today. According to the text, the rate of drug use among students has declined in ...
- 2245: Nuclear Energy
- ... of uranium oxide, the uranium oxide is a gas form of the solid uranium. These fuels which cause the radioactive particles usually are always highly radioactive themselves. Because of this all the power plants take high safety standards and use special shields to prevent leakage. Usually the leakage can cause nuclear contamination. This means they must take high safety standards. After nuclear fission has occurred many of the thermal neutrons are moving at thermal neutrons are moving at thermal velocities which are harder to be absorbed, so they rely on constructional details. Usually ... use thick medals such as lead or tungsten, usually now though the barrier is made of concrete. The average shield of a power plant twelve to fourteen feet in diameter and fifteen to twenty feet high. This creates a problem with gamma ray leakage out into the biomes. this usually would only happen in a time of crises, this is why shields are so highly needed. Because of this factor ...
- 2246: Roll Of Thunder, Hear My Cry
- ... fairly minor people in the book, their characters are used to inforce and strengthen the themes of the novel. We first meet TJ Avery when Cassie, Stacey, Little Man and Christopher-John are walking to school. Right from the very start we find out that none of them actually likes TJ, except for Stacey. The reader sees that he is a liar, a cheat and a coward. He is ashamed of ... ways that he lets them down is when he gets Miz Logan fired. He went up to the store and told Kaleb Wallace that Miz Logan failed him on purpose and that she was destroying school property. ...I got fired...Harlen Granger came to the school with Kaleb Wallace and one of the school board members. Somebody told them about those books I d pasted over...but that was only an excuse. (Pg 151) This highlights some of the themes ...
- 2247: A Separate Peace: Comparison and Contrast Between Book and Movie
- ... that the movie was a novel before it was a movie, are similar and dissimilar at times. Both take place at Boys Schools, although the air surrounding both schools are not quite the same. One school is dedicated to preparing its students for college and the other was simply a school for boys, a place where mothers sent their sons to be educated without letting them be entangled by the outside world. The climates of the two schools were similar in the fact that they had ... Summer Session, while the members of the Dead Poets Society seemed to prefer the colder climate. Speaking of the SSSS, the time at which the story of Devons students begins is a sort of summer school, while the beginning of the story of the students of Wellton begins on the first day of school. Some of the events that happen between the two schools have similarities, but even in the ...
- 2248: History of Computers
- ... for over a half-century, but its ancestors have been around for 2000 years. However, only in the last 40 years has it changed the American society. From the first wooden abacus to the latest high-speed microprocessor, the computer has changed nearly every aspect of people's lives for the better. The very earliest existence of the modern day computer's ancestor is the abacus. These date back to almost ... the military. New weapons systems were produced which needed trajectory tables and other essential data. In 1942, John P. Eckert, John W. Mauchley, and their associates at the University of Pennsylvania decided to build a high-speed electronic computer to do the job. This machine became known as ENIAC, for "Electrical Numerical Integrator And Calculator". It could multiply two numbers at the rate of 300 products per second, by finding the ... wire it to perform whatever task he wanted the computer to do. It was, however, efficient in handling the particular programs for which it had been designed. ENIAC is generally accepted as the first successful high-speed electronic digital computer and was used in many applications from 1946 to 1955 (Dolotta, 50). Mathematician John von Neumann was very interested in the ENIAC. In 1945 he undertook a theoretical study of ...

- 2250: The Life of the Great William Shakespeare
- ... oldest son, William Shakespeare was born in 1564, and they baptized him in Stratford-upon-Avon, Warwickshire. The Shakespeare family was not rich and therefore could not afford to send their children to a "private school," and it is commonly accepted that the children attended Stratford's Grammar School. "William's education consisted of mostly Latin studies (learning to read, write, and speak the language almost fluently), and the study of some of the classic historians, moralists, and poets. Of course, they also had ... toward the field of their choice" (Britannica 253-254). William Shakespeare, however, did not go to the university, and instead tried his hand at life with only the education he received at the local grammar school. This surprises most historians; they find it hard to believe that one with minimal education could write such historically accurate plays. This generally makes us assume that he liked school, and did well in ...
