Marie Curie's birthplace, 16 Freta Street, Warsaw, Poland. Maria Salomea Skłodowska-Curie [a] (Polish: [ˈmarja salɔˈmɛa skwɔˈdɔfska kʲiˈri] ⓘ; née Skłodowska; 7 November 1867 – 4 July 1934), known simply as Marie Curie (/ ˈ k j ʊər i / KURE-ee; [1] French: [maʁi kyʁi]), was a Polish and naturalised-French physicist and chemist who conducted pioneering research on ...
Pierre and Marie Curie in their laboratory, circa 1900.. International scientific research into the atom began with the discovery of X-rays by German physicist Wilhelm Röntgen on November 8, 1895, in Würzburg, following the observation of a strange, pale glow coming from a luminescent screen placed, by chance, on a table at a distance from a Crookes tube.
In 1898, Pierre and Marie Curie discovered that pitchblende, an ore of uranium, contained a substance—which they named radium—that emitted large amounts of radiation. Ernest Rutherford and Frederick Soddy identified that atoms were breaking down and turning into different elements. Hopes were raised among scientists and laymen that the ...
Pierre and Marie Curie discovered that uranic rays vary in intensity depending on the uranium ore. Starting in 1898, they aimed to isolate the element responsible for this phenomenon. By manually refining hundreds of kilograms of uraninite, they discovered the first element in July, which they named polonium in honor of Marie's homeland.
Polonium was discovered on 18 July 1898 by Marie Skłodowska-Curie and Pierre Curie, when it was extracted from the uranium ore pitchblende [4] and identified solely by its strong radioactivity: it was the first element to be discovered in this way. [5]
Fat Man was the second nuclear weapon to be deployed in combat after the US dropped a 5-ton atomic bomb, called "Little Boy," on the Japanese city of Hiroshima.
The Curie is a unit of measurement (3.7 × 10 10 decays per second or 37 gigabecquerels) used to describe the intensity of a sample of radioactive material and was named after Marie and Pierre Curie by the Radiology Congress in 1910.
