Can u please do American woman. On the other hand, the uranic rays, discovered in by Henri Becquerel, raised a puzzling problem. Uranium compounds and minerals appeared to maintain an undiminished ability to blacken a photographic plate over a period of several months. Stunt cock What was the source of this inexhaustible energy that apparently violated the Carnot principle that energy can be transformed but never be created or destroyed? Pierre Curie, already a famous physicist for his work on magnetism and crystal symmetry, had a feeling that the phenomenon was quite extraordinary, and he helped his wife reach a decision in her choice of thesis topic. After initial excitement, interest in the new rays had faded rapidly. One reason was the proliferation of false or doubtful observations of radiation similar to uranic rays in a variety of substances. The topic was moribund when Marie Curie entered the scene. However, within eight months in she discovered two elements, polonium and radium, founding a new scientific field—radioactivity.1 Dec Results were not long in coming. Just after a few days, Marie discovered that thorium gives off the same rays as uranium. Her continued systematic studies of the various chemical compounds gave the surprising result that the strength of the radiation did not depend on the compound that was being studied. 19 Mar Marie Curie, shown in Fig. 1, devoted her life to her research and her family. She discovered two new elements, radium and polonium, and was the first women to win a Nobel Prize. She is also the only woman to win two Nobel prizes in different fields, namely chemistry and physics.

Marie Curie thus became the first woman to be accorded this mark of honour on her own merit. One woman, Sophie Berthelot, admittedly already rested there but in the capacity of wife of the chemist Marcelin Berthelot In point of fact - as the press pointed out - this initiative was symbolic three times over. Marie Curie was a woman, she was an immigrant and she had to a high degree helped increase the prestige of France in the scientific world.

Sorbonne-bred physicist Pierre Curie had been noodling with crystals and magnetism since the early s. He was a professor at the School of Physics in Paris when one of his students, Marie Sklodowska , caught his eye. They wed in , and theirs was both a happy marriage and a fruitful professional collaboration. A colleague of the Curies, Henri Becquerel , paved the way for their groundbreaking research with his discovery of spontaneous radioactivity in
