=Marie-Sophie Germain=

She started her interest in mathematics when she was 13 years old. She was forced to stay indoors because of the war and most of the time she studied mathematical books that filled her with much curiosity and enjoyment. Her parents were not very fond of her studies mostly because of her gender as a women but that did not disturb her love for the subject. in fact they disapproved of it so much that they would eliminate amenities such as clothes or light. She was self-taught and soon enough her cousin and later her parents would support her studies.
 * Start of Interest In Mathematics**

**Related Math Problem(s)**She is famous for her work in number theory, as follows: Sophie Germain's Identity -

States that for any {x,y} X4 + 4y4 = ((x + y)2 + y2)((x – y)2 + y2) = (x2 + 2xy + 2y2)(x2- 2xy + 2y2)

Sophie Germain prime -States that any prime plug it in to 2p+1,where p=prime, is also prime.

Germain curvature - (K1+K2)/2 are part of a normal curvature


 * Contributions**

=
Sophie Germain contributed many things to the mathematics world. She was one of the only individuals interested in pursuing the elasticity theory. She also did much work on Fermat's Last Theorem. As well as winning the grand prize for the Paris Academy of Sciences for her essay on the subject. ======

She was never married.

 * Social/Educational Climate**

=
Sophie lived during the French revolution. Women did not have many rights then. Her parents kept her from studying because it was unfit for women, back then, to be interested in math. She was denied admittance to the École Polytechnique, a high educational facility because women were not allowed to be in there ======


 * Nationality**

=
 Two of her philosophical works, Pensées diverses and Considérations générales sur l'état des sciences et des letteres aux différentes epoques de leur culture were published after her death ======

 She had one younger sister, named Angélique-Ambroise, and one older sister, named Marie-Madeline
 Her nephew Armand-Jacques Lherbette published some of her work after her death

Joseph Louis Lagrange was Sophie Germains main mentor in math. She also gained a lot of knowledge from her fathers massive library that she was frequently in.
