- Aging Theories - 1,709 words
Aging Theories This report outlines the main theories of how the process of aging works. Since researchers have not discovered a universally-accepted theory of aging, the theories discussed are potential explanations of how we age. The likelihood of each hypothesis is considered roughly equal. The different theories discussed focus on the workings of different parts of the body, from the molecular level of DNA mutations and replication, to the organism level of becoming "worn out." Aging is a very complex and gradual process, and its ongoing operation is present to some degree in all individuals. It is a journey to the maturity, as well as to the degeneration of the body. Because aging affec ...

- Madame Curie - 415 words
Madame Curie Discoverer of Radium Originally named Marja Sklodowska, Marie Curie was born in Warsaw on Nov. 7, 1867. Her father taught high school physics. In 1891 she went to Paris (where she changed her name to Marie) and enrolled in the Sorbonne. Two years later she passed the examination for her degree in physics, ranking in first place. She met Pierre Curie in 1894, and they married in 1895. Marie Curie was interested in the recent discoveries of radiation. Wilhelm Roentgen had discovered X rays in 1895/ ~ 1896 Antoine Henri Becquerel had discovered that the element uranium gives off similar invisible radiations. Curie thus began studying uranium radiations, and, using piezoelectric tec ...

Marie And Pierre Curie Marie Sklodowska ( a.k.a.) was born in Warsaw in 1867. Her parents were teachers who believed strongly in the importance of education. Marie had her first lessons in physics and chemistry from her father. She had a brilliant aptitude for study and a great thirst for knowledge; however, advanced study was not possible for women in Poland. Marie dreamed of being able to study at the Sorbonne in Paris, but this was beyond the means of her family. To solve the problem, Marie and her elder sister, Bronya, came to an arrangement: Marie should go to work as a governess and help her sister with the money she managed to save so that Bronya could study medicine at the Sorbonne. ...

... not being used. Theyre the work of separation and analysis began. Marie performed the chemical separations, while Pierre did the measurements after each successive step. Physically it was heavy work for Marie. She processed 20 kilos of raw material at a time. She had to clear away pine needles and debris, then she had to undertake the work of separation. In that shed they performed their experience and Marie writes that they spent the best times of their lives. Sometimes they could not do their processing outdoors, so the harmful gases had to be let out through the open windows. The only furniture was an old, worn pine table where Marie worked with her costly radium fractions. Since the ...

- Marie Curie - 305 words
Marie Curie The year was 1919. Europe had been ravaged by World War I, and radium was far too expensive for a scientist of modest means to afford for experiments, even one as famous as Madame Marie Curie. As a result, Madame Curie's ground-breaking research had reached a virtual standstill... For my biography, I chose Marie Curie. Marie Curie was born in 1867 in Warsaw, Poland as Manya Sklodowska. She was not only a great chemist, famous for her work on radioactivity, but she broke boundaries for woman also. In fact with the help of her husband, Pierre, made up that word. Madame Curie who was the first woman to win a Nobel Peace Prize won two for her work in Physics and Chemistry. Her family ...

- More Than Hundred Years Passed Since Marie And Pierre Curie Won The Nobel Prize For Discovering Radioactive Elements Polonium - 724 words
More than hundred years passed since Marie and Pierre Curie won the Nobel Prize for discovering radioactive elements polonium and radium. The scientific world was excited with the newly discovered force of nature, but they soon realized that that the discovery was not the best for human race. They soon learned that the great discovery was a threat to health. Unfortunately, long time went by until their concerns were taken seriously. Marie Curie denied that radiation was bad for health even though everyone around her, who was exposed to radiation, was dyeing from leukemia. She never fully acknowledged that her work had ruined her health Marie curie herself was chronically ill and nearly blind ...

- Nuclear Energy - 1,925 words
Nuclear Energy From Theory to Practice The nuclear age began in Germany, in the 1930s in the lab of chemist Otto Hahn. Hahn was attempting to produce radium (In great need during the war) by bombarding uranium atoms with neutrons. To his surprise, he ended up with a much lighter element, barium. That was 1938, This started the race for the power of the atom. Just four years later Canada entered nuclear age in cooperation with the british. Wartime, 1942: The British wanted a safe place to conduct nuclear experiments; Since their country feared invasion by the nazi's or bombing attacks, Canada provided the haven the british needed in return for a opportunity to work in the project. The leader ...

- Radon - 569 words
Radon Radon is an element that is on the periodic table of elements. It is a member of the family called the noble gases, which is group number 18. Radon is a gas. It is a gas at 298 k. it is the heaviest known mononuclear gas at that temperature. Radon is also colorless. When it is cooled below the freezing point, radon exhibits a brilliant phosphorescence, which becomes yellow as the temperature is lowered. At the temperature of liquid air it is sort of an orangish-red. The noble gases can be found on the very right side of the periodic table of elements. Radon has been around for quite some time. Radon comes from the element radium, which is derived from the element uranium. After radium ...

... s in their psychic "sorties" to locate Soviet submarines. Alexander seems to have an extremely eclectic background -- he received a PhD. in Thanatology (the study of death and near-death experiences) from Georgetown University under the tutelage of the celebrated Dr. Elisabeth Kubler-Ross. Apparently, Alexander is a "mind-control" junkie, having studied everything from Silva Mind Control, to a stint in a Buddhist monastery. When the National Research Council issued its findings that there was no evidence of paranormal phenomena, Alexander wrote a critique of the report that was both passionate and eloquent. In this rebuttal, he compared the report's apparent a priori conclusions to the C ...

The Life Of Madame Curie The Life of Madame Curie Madame Curie was born Maria Sklodowska on November 7,1867, in Warsaw Poland. Maria was the fifth and youngest child of Bronsilawa Boguska, a pianist, singer, and teacher, and Wladyslaw Sklodowski, a professor of mathematics and physics. Maria's accomplishments began at a young age; by the time she was sixteen she had completed secondary school and taken work as a teacher. In 1891 Maria went to Paris, while in Paris Marie attend Sorbonne University and began to follow lectures of many already well known physicists--Jean Perrin, Charles Maurain, and Aime' Cotton. It was during this time that Marie finally turned towards mathematics and physics. ...

... rm of authority, and therefore it is capable of the same or greater evils. How many atrocities have been justified by the claim that God is on our side? - DEATH People are dying constantly in Slaughterhouse-Five, and of course the destruction of Dresden brought death on a massive scale. Vonnegut follows every mention of death with that familiar phrase, So it goes. In this way he attempts to find a saner attitude toward death by emphasizing that death is a common aspect of human existence. Billy Pilgrim finds consolation in the Tralfamadorian notion that people who are dead in the present remain alive in the times of their past. Perhaps the author is saying that we too should be consoled: ...
