![]() ![]() ![]() It did eventually catch up to her however, and she died of aplastic anemia. Millikan oil-drop experiment, first direct and compelling measurement of the electric charge of a single electron. Also, she survived a very long time for someone who messed around with radioactive materials. Some interesting facts about Marie Curie are that her name isn't actually Marie, but is instead Maria by birth! SHe changed it after marrying Pierre, and it is how she is most known. (U.S.A.), as the second son of the Reverend Silas Franklin Millikan and Mary Jane Andrews. ![]() She also measured how radium, polonium, and uranium affected the air, which allowed her to see just how radioactive each was. (1868-1953) Robert Andrews Millikan was born on the 22nd of March, 1868, in Morrison, Ill. He is best known for his famous oil-drop experiment, which helped to determine the charge of an electron and led to a more accurate understanding of atomic structure. The theory of the four elements was much more well-received. Robert Millikan was an American physicist who made significant contributions to the field of atomic theory. These discoveries came from her numerous experiments involving radium, which she would usually get from pitchblende that she crushed. Atomic Theory: The Ancient Greeks proposed two basic theories about the elements, one which theorized there were four elements, earth, air, fire, and water, and the other that proposed that each substance was composed of small individual particles of that substance called atomies. She had also discovered both Polonium and Radium, naming them after Poland and the word Ray respectively. Marie's biggest contribution to the atomic theory was that atoms' arrangement did not lead to them being radioactive, but that the atoms themselves were radioactive instead. In 1886 he entered Oberlin College in Ohio. When Millikan was seven, his family moved to Maquoketa, Iowa, where he attended high school. Marie had eventually gone to Paris and married Pierre Curie, and after feeling homesick, had returned to Poland. Born in Morrison, Illinois, Robert Andrew Millikan was the second son of the Reverend Silas Franklin Millikan and Mary Jane Andrews. She worked as a tutor to gain the funds for both herself and her sister to receive education, and in her free time, Marie would read up on chemistry books. Employing a photonic interpretation of cosmic rays, Millikan developed a theory of their origin in 1928, the 'atom-building hypothesis.' In his summary of the argument, cosmic rays were the 'birth cries' of atoms, a phrase which quickly achieved a good deal of notoriety among both the scientific and the lay publics. How did Robert Millikan contribute to the atomic theory Flexi Says: He sprayed tiny drops of oil into a chamber. She had many obstacle in life to overcome, such as the fact that she was a girl, which meant she could not get higher education, and the fact that her dad could not put her into university because of money constraints. She had her mother die when Marie was only 10, and this led Marie to be put into boarding school. Marie Curie was born in Warsaw, Poland, and lived from 1867-1934. ![]()
