Sophie Germain

Sophie GermainSophie Germain2Sophie Germain was a French mathematician physicist and philosopher.

She was born on the 1 April 1776 at Paris and she died when she was 55 years old on the 27 June 1831 at Paris too .

Sophie Germain was the first and only woman who demonstrated Fermat’s Last Theorem or number theory.


There aren’t invalid integers x , and z such as :  xn + yn = zn  as soon as n is an integer strictly upper to 2.

In case n = 1, the equation xn + yn = zn corresponds to the usual addition.

In case n = 2, this equation has another infinity of not invalid solutions, the smallest of which is (3, 4, 5)  :   32 + 42 = 52
