This week in science history: Marie Curie dies


The great French scientist pioneered atomic physics, and twice won a Nobel Prize.

In its eulogy for Marie Curie, who dies on July 4, 1934, The New York Times expressed: “Couple of people contributed more to the general welfare of humankind and to the headway of science than the unobtrusive, self-destroying lady whom the world knew as Madam Curie. Her age making disclosures of polonium and radium, the consequent respects that were offered to her – she was the main individual to get two Nobel prizes – and the fortunes that could have been hers had she needed them, didn’t change her method of life.

“She remained a laborer in the reason for science … What’s more, subsequently she vanquished awesome privileged insights of science as well as the hearts of the general population the world over.”

Conceived Maria Sklodowska in Warsaw, Poland, on November 7, 1867, Marie Curie turned into the principal lady to win a Nobel prize and, as The Times noted, at the time she was the main individual to win the honor twice.

In 1891 she went to Paris and learned at the Sorbonne, where she was perceived in material science and arithmetic. She met Pierre Curie, educator in the School of Physics, in 1894 and they were hitched the next year. She succeeded her significant other as leader of the material science research facility at the Sorbonne, picked up her Doctor of Science degree in 1903, and following Pierre’s passing in 1906 had his spot as teacher of general physical science in the Faculty of Sciences. It was the first run through a lady had held the position.

The Curies based upon crafted by French physicist Henri Becquerel, who in 1896 had been researching X-beams, which had been found the earlier year.

As indicated by, “Coincidentally, [Becquerel] found that uranium salts unexpectedly transmit an entering radiation that can be enlisted on a photographic plate. Additionally examines made it unmistakable that this radiation was something new and not X-beam radiation.”

The Curies made Becquerel’s work a couple of strides further. Marie was examining uranium beams and discovered they were not subject to the uranium’s shape, but rather on its nuclear structure. Her hypothesis made another field of study, nuclear material science. She authored the adage “radioactivity”.

Marie and Pierre worked with the mineral pitchblende, a type of the crystalline uranium oxide mineral uraninite, which is around 50 to 80% uranium. Through this exploration, they found the radioactive components polonium and radium. In 1902 the Curies declared that they had delivered a decigram of unadulterated radium, exhibiting its reality as an extraordinary synthetic component.

In 1903, Marie and her better half won the Nobel prize in material science for their work on radioactivity. In 1911, Marie won her second Nobel, this time in science.

By the late 1920s her well-being was starting to fall apart. She kicked the bucket from leukemia, caused by presentation to high-vitality radiation from her exploration. The Curies’ oldest little girl Irene was additionally a researcher, and furthermore won a Nobel prize for science.
