## Early Life and Education of Évariste Galois

Évariste Galois, the renowned French mathematician, was born in **Bourg-la-Reine**, a town near Paris, in 1811. Growing up in a household that valued intellectual pursuits, Galois was exposed to philosophy and literature from an early age. However, it was his education at the **Collège Royal de Louis-le-Grand** that ignited his passion for mathematics.

At the **Collège Royal de Louis-le-Grand**, Galois studied under the guidance of Louis Richard, a distinguished mathematician of the time. It was during this period that Galois began to delve into the study of algebra, with a particular focus on solving **algebraic equations**. He was determined to unravel the conditions under which equations could be solved by radicals, a question that had puzzled **mathematicians** for centuries.

Despite his exceptional talent and dedication, Galois faced several challenges along his educational journey. He experienced setbacks, such as being rejected from the prestigious École Polytechnique and later being expelled from the **École Normale Supérieure** due to his involvement in republican activities during a politically turbulent period.

In summary, Évariste Galois’ early life and education set the foundation for his future work in mathematics. The rigorous education he received at the **Collège Royal de Louis-le-Grand** and his relentless pursuit of solving **algebraic equations** by radicals laid the groundwork for his revolutionary contributions to the field.

## Galois’ Revolutionary Contributions to Mathematics

Évariste Galois, a brilliant mathematician of the 19th century, made extraordinary contributions that forever changed the landscape of mathematics. One of his most groundbreaking achievements was the introduction of **solvability by radicals**, a concept that transformed the study of **algebraic equations**.

It was Galois who realized that solving equations required a deeper understanding of the relationships between the roots of the equation and their permutations. This insight led him to develop the theory of groups, with a specific focus on **automorphisms** and their solvability.

Through his profound insights, Galois demonstrated that an equation can be solved by radicals only if its associated group of **automorphisms** is solvable. This revolutionary idea paved the way for a fresh approach to solving equations beyond the quartic degree, challenging the conventional methods used by **mathematicians** of his time.

Although Galois did not formally define the concepts of group, subgroup, and coset, his innovative ideas laid the foundations for modern **group theory**. His work not only expanded the horizons of **mathematicians** but also opened up a whole new world of **abstract concepts** that continue to shape mathematical research today.
