Here's why:
* She was a mathematician, not an inventor. Her work focused on proving theorems, developing theories, and solving problems in various areas of mathematics and physics.
* Her contributions were theoretical, not practical. While her work had implications for practical applications, she didn't create any tangible devices or products.
Here are some of her key achievements:
* Germain primes: She studied and explored a specific type of prime number, now known as Germain primes. These primes have specific mathematical properties.
* Fermat's Last Theorem: She made significant contributions to the understanding of Fermat's Last Theorem, although she didn't solve it.
* Elasticity theory: She developed important theoretical models for understanding the behavior of elastic materials, which have applications in engineering.
Sophie Germain's contributions were primarily theoretical and laid the foundation for future research in various fields. She is remembered as a pioneer in mathematics and physics.
