Google honours Ștefania Mărăcineanu with a doodle on Romanian physicist’s 140th birth anniversary, pays tribute to her legacy WorldsAdvisor.Com

Google on Saturday paid Ștefania Mărăcineanu a tribute on her 140th birthday by dedicating a doodle. Mărăcineanu, a Romanian physicist, was one of the pioneering women in the discovery and research of radioactivity. WorldsAdvisor.Com

The physicist formed Romania’s first laboratory for the study of Radioactivity upon her return after working for four years at the Astronomical Observatory in Meudon. WorldsAdvisor.Com

She dedicated her time researching artificial rain for which she travelled to Algeria to test her results. Mărăcineanu also studied the link between earthquakes and rainfall and was also the first to report that there is significant increase of radioactivity in the epicentre leading up to an earthquake.

In 1910, Mărăcineanu graduated with a physical and chemical science degree and started her career as a teacher at the Central School for Girls in Bucharest. There she also earned a scholarship from the Romanian Ministry of Science. WorldsAdvisor.Com

She then did graduate research at the Radium Institute in Paris. The Radium Institute was quickly becoming a worldwide centre for the study of radioactivity under the direction of physicist Marie Curie. Mărăcineanu began working on her PhD thesis on polonium, an element that Curie discovered. worldsadvisor.com

While studying the half-life of polonium, Mărăcineanu realised that the half-life seemed dependent on the type of metal it was placed on. This led her to wonder if the alpha rays from the polonium had transferred some atoms of the metal into radioactive isotopes.

Mărăcineanu's work led to the first example of artificial radioactivity. The physicist finished her PhD in physics within two years at Sorbonne University in Paris.

When Irène Currie, daughter of Marie Curie, and her husband received a joint Nobel prize for their discovery of artificial radioactivity, Mărăcineanu asked that her role in the discovery be recognised. She didn't contest the Nobel prize but wanted recognition for her contribution. WorldsAdvisor.Com

In 1936, her work was recognised by the Academy of Sciences of Romania where she was also elected to serve as a Director of research. However, she never got global recognition for her discovery. WorldsAdvisor.Com
