In 1894, Marie met Pierre Curie, a distinguished physicist working on crystallography and magnetism. Their mutual passion for science led to a deep personal and professional partnership. They married in 1895, and their collaboration soon yielded significant scientific discoveries.
The Curies were inspired by Henri Becquerel’s discovery in 1896 that uranium salts emitted rays capable of penetrating photographic plates. Intrigued by this phenomenon, Marie Curie chose to investigate further as part of her doctoral thesis. She began by examining uranium rays and discovered that they remained constant regardless of the uranium’s physical or chemical state, leading her to hypothesize that the radiation was coming from the atomic level.
Discovery of Polonium and Radium
Marie’s hypothesis about the atomic origin of radiation marked the beginning of her monumental contributions to science. She coined the term “radioactivity” to describe the spontaneous emission of rays from certain elements. With Pierre’s assistance, she began a systematic search for other substances that exhibited similar properties.
In 1898, the Curies discovered two new elements: polonium (named after Marie’s homeland, Poland) and radium. Isolating these elements required processing tons of pitchblende, a uranium-rich mineral, under grueling conditions. Their discovery of radium, in particular, was revolutionary because of its intense radioactivity, which was millions of times greater than that of uranium.
