Sophie Germain is one of the greatest women mathematicians. Sophie started her journey in Paris, France. She was born on April 1, 1776, raised by both parents, her father Ambroise-Fran?ois Germain, her mother Marie-Madeleine Germain. Sophie decided her career goals at a surprisingly early age. She was born during the time of the French Revolution which caused her to stay indoors most of the time. One day she was going through the books in her fathers’ library, and became interested in many books. At age thirteen while she read an “Account of the death of archimedes at the hands of a Roman soldier,” (Germain Biography). She mainly read books which brought up her interest about mathematics. Little did she know than that she was to become a great mathematician soon. After reading many books from her father’s’ library Sophie decided to start teaching herself. She would bring a notebook, and a pencil so thashe could practice the steps herself. Although Sophie really enjoyed learning math, her parents thought that it was a disgrace for a female to be doing such things. So to keep her parents from knowing she tried to study at night, but the parents still found ways to stop her from studying, they did things such as “turning off the heat, and lights,” (Agnes Scott). This still didn’t stop her, because her strive to learn something new was so strong and important to her that she wouldn’t stop. At night she would use candles, and extra quilts to provide heat and light to her. Later the parents found out again, and decided that there was nothing they could do, so they left her alone. This was only the beginning of Sophie’s amazing journey. By reading these books, she was able to learn very hard calculus without the help of anyone else,which is pretty remarkable since many people usually struggle with calculus, her ability to do this on her own is great. When Sophie was 18 years old she applied herself for Ecole Polytechnique which was meant to train mathematicians and scientists, but the problem of this was only men were allowed to sign up for this program. Even though these were her struggles, her friend gave her the notes from the lectures and she used to study off of them. At the end of the year, Sophie sent a letter to the head of the group, and he was amazed when he found the the person with such crafty work was a women. Sophie soon sent a letter to gauss explaining her theories, Gauss was also amazed by this and took her in as her mentor. After learning almost everything she could from Gauss, she still realized that she had a lot to learn from the wonders of math. Sophie Germain came up with the number theory, which is widely used all across the world. The theory is n xp + yp = zpWhich was based off of Fermat’s Last Theorem for odd prime p. After Sophie came up with this theory the way people reacted was just unimaginable. Gauss had said, “How can I describe my astonishment and admiration on seeing my esteemed correspondent M leBlanc metamorphosed into this celebrated person… when a woman, because of her sex, our customs and prejudices, encounters infinitely more obstacles than men in familiarising herself with number theory’s knotty problems, yet overcomes these fetters and penetrates that which is most hidden, she doubtless has the most noble courage, extraordinary talent, and superior genius.” Sophie herself said, “In describing the honourable mission I charged him with, M. Pernety informed me that he made my name known to you. This leads me to confess that I am not as completely unknown to you as you might believe, but that fearing the ridicule attached to a female scientist, I have previously taken the name of M. LeBlanc in communicating to you those notes that, no doubt, do not deserve the indulgence with which you have responded.” These quotes simply showed how great Sophie Germain not only thought about herself, but what others closest to her thought about her. Sophie Germain inspired many woman to come about how it does not matter about your gender, but what truly matters is your talent and capability to do the things you like. This is why Sophie Germain is undoubtedly one of the man great mathematicians, not because she is a woman because she worked hard so that she could achieve her dreams.
