Google Doodle celebrates the 140th anniversary of the birth of Romanian physicist Stefania Maracineanu | India News



NEW DELHI: Google celebrated Romanian physicist’s 140th birthday on Saturday Stefania Maracineanu with a doodle. Maracineanu was one of the pioneering women in the discovery and research of radioactivity.
She was born on June 18, 1882 in Bucharest. His research on polonium led to what is most likely the first example of artificial radioactivity.
The doodle features Maracineanu working on polonium in a lab. Maracineanu has devoted his time to research on artificial rain.
Maracineanu obtained a degree in physical and chemical sciences in 1910, beginning her career as a teacher at the Central School for Girls in Bucharest. While there, Maracineanu obtained a scholarship from the Romanian Ministry of Science. She decides to pursue graduate studies at the Institut du Radium in Paris.
The Radium Institute quickly became a world center for the study of radioactivity under the direction of physicist Marie Curie. Maracineanu began working on his doctoral thesis on polonium, an element discovered by Curie.
While researching the half-life of polonium, Maracineanu noticed that the half-life seemed to depend 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. His research resulted in what is most likely the first example of artificial radioactivity.
Maracineanu enrolled at the Sorbonne University in Paris to complete her doctorate in physics, which she obtained in just two years! After working for four years at the Astronomical Observatory of Meudon, she returned to Romania and founded the first laboratory in her native country for the study of radioactivity.
Maracineanu devoted his time to research on artificial rain, which included a trip to Algeria to test his results. She also studied the link between earthquakes and precipitation, becoming the first to report that there is a significant increase in radioactivity in the epicenter leading to an earthquake.
In 1935, Irène Currie, daughter of Marie Curie, and her husband received a joint Nobel Prize for their discovery of artificial radioactivity. Maracineanu did not contest the Nobel Prize, but asked that his role in the discovery be recognized.
Her work was recognized by the Romanian Academy of Sciences in 1936, but she never received worldwide recognition for her discovery.
