The cyclist who relies on the rear brake for general stopping can get by until an emergency arises, and, in a panic, he or she grabs the unfamiliar front brake as well as the rear, for extra stopping power.
View full size image. Marie Curie was a physicist and chemist and a pioneer in the study of radiation. She and her husband, Pierre, discovered the elements polonium and radium. Together, they were awarded the Nobel Prize for Physics in 1903, and she received another one, for Chemistry, in 1911.Her work with radioactive materials doomed her, however. She died of a blood disease in 1934.n 1911, after Pierreâs death, Marie was awarded a second Nobel Prize in Chemistry for her discovery of the elements polonium and radium. Later years. Marie continued to do research in radioactivity.
After the war she continued her fundraising for the Radium Institute, even traveling to the U.S. in 1921. There, in addition to donations and publicity, she received a gift of one gram of Radium-a gift that effectively doubled her research supply of the costly substance. By 1934, Curie's health was failing rapidly. The toll of heavy exposure to radiation was at last overpowering her impressive constitution. She did live to see Ir ne and son-in-law Fr d ric Joliot-Curie discover artificial radiation, but not long enough to see them win the Nobel Prize for Chemistry for this achievement. On 4 July 1934 she succumbed to aplastic anemia, or leukemia, induced by radiation exposure.
