Mathematics After Evariste Galois in The Story of Algebra 🍂🍁🦋 After Galois, algebra never looked the same again. It is no more restricted to ordinary number systems and equations. By the end of 19th century, algebra expanded to the study of abstract structures such as groups, rings, fields, modules and vector spaces. Mathematicians started to study abstract algebra as a vector space over a field that is also a ring. The study of these abstract algebraic structures helped mathematicians to lib
