Mary Beth Ruskai (1944–2023), proved subadditivity of quantum entropy, bounded the electrons in an atom, advocate for women in mathematics; Beulah Russell (1878–1940), American mathematician; Alma Johanna Ruubel (1899–1990, Estonian mathematician, developed curvilinear representational geometry
Irène Joliot-Curie [10] and Dorothy Hodgkin [11] were also nominated for the Nobel Prize in Physics, but received a Nobel Prize in Chemistry in 1935 and 1964, respectively. Lise Meitner is the female physicist the most nominated, 16 times for Physics and 14 times for Chemistry. [20] About 1.7% of the Nobel nominations in Physics up to 1970 ...
She observed that radioactive recoil, which had been discovered by Harriet Brooks in 1904, could be a new way of detecting radioactive substances. They soon discovered two more new isotopes, bismuth-211 and thallium-207. [31] [32] [33] Meitner was particularly interested in beta particles. By this time, they were known to be electrons. Alpha ...
The current theoretical model of the atom involves a dense nucleus surrounded by a probabilistic "cloud" of electrons. Atomic theory is the scientific theory that matter is composed of particles called atoms. The definition of the word "atom" has changed over the years in response to scientific discoveries.
In the judgment of the most competent living mathematicians, Fräulein Noether was the most significant creative mathematical genius thus far produced since the higher education of women began. In the realm of algebra, in which the most gifted mathematicians have been busy for centuries, she discovered methods which have proved of enormous ...

The Latest: Mathematicians Discovered Something Mind-Blowing About the Number 15 In a nutshell, an elliptic curve is a special kind of function. They take the unthreatening-looking form y²=x³+ax+b.
This is a historical list dealing with women scientists in the 20th century. During this time period, women working in scientific fields were rare. Women at this time faced barriers in higher education and often denied access to scientific institutions; in the Western world, the first-wave feminist movement began to break down many of these ...
