Marie Curie Essays - Marie Curie, Nobel Laureates In Physics

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 was one that took for good education. For this reason, she left Poland and went to Paris to study mathematics, chemistry and physics. She studied at the Sorbonne and in 1891, she became the first woman to teach there. While she was in France, she took to their way of spelling her name, Marie. Around that time she met Pierre Curie who taught physics at the University of Paris. They soon started to conduct research on radioactive substances and before long they got married. In 1903, the Curies, along with, Antoine Henri Bacquerel, a French physicist won the Nobel Peace Prize for their discoveries in Physics. Madame Marie continued working on radioactive elements and won the 1911 Nobel Prize for chemistry for isolating radium and studying its chemical properties. In 1914, Madame Curie helped found the Radium Institute in Paris, and was the Institute's first director. In 1934 she died of leukemia that was probably induced by the extensive exposure to high levels of radiation involved by her studies. In dedication to her death, the Radium Institute was renamed the Curie Institute in her honor. Biographies

League of Nations failure essays

League of Nations failure essays Why did the League of Nations failed in the 1930s? The break down of the League did not happen overnight but rather progressively. An important reason for this could be because America was not able to loan huge amounts of money the Depression that followed on after the Wall Street Crash in 1929. Without the badly needed money, the Dawes Plan could not be put into effect any longer. Therefore, economically, Europe was spiralling down into deeper depression. America was also a powerful country, if they had became a member, the League would have stood a chance of enforcing economic sanctions on Japan in the Manchuria incident, and Italy in the Abyssinia incident. It is true that other members like France and Britain could have enforced it themselves, but the consequences are that trade would be disrupted and lead to a dropout of international relations. For example, when the issue of activating sanctions on Italy was discussed, France was not willing to co-operate because France saw Italy as a valuable ally that would protect France f rom Germany. However, one can argue that even if France had agreed, these sanctions were more than possible to be broken soon. In fact, to make it worse, the outcomes of the Manchuria and Abyssinia crises caused the League to lose Japan and Italy as important and powerful members. France and Britain were meant to provide firm support in times of crisis like these, but they were both too preoccupied by the self interests of their own nations to tackle the League problems. Their country came first instead. The League did not have an army for them to stop the Italians from invading Abyssinia. Again, Britain and France were meant to help provide the majority of these troops but they were reluctant to. This is due to the fact that at this time, both countries could not risk sacrificing military reinforcements. To them, it was not practical to send their own troops all over the world, leaving their own bord...
