Summary of the book “ A Mathematician’s Apology” by G H Hardy (Mentor of Shri Srinivasan Ramanujan)
"A Mathematician's Apology" is a book written by G.H. Hardy, a prominent mathematician of the early 20th century. The book is a personal reflection on the nature of mathematics and the role of a mathematician in society. It was first published in 1940 and has since become a classic in the field.
The book is divided into two parts. The first part focuses on the aesthetics of mathematics, arguing that mathematics is a creative art form that is both beautiful and timeless. Hardy suggests that the beauty of mathematics lies in its pureness and abstraction, rather than in its practical applications. He also discusses the idea that mathematicians do not create mathematical concepts, but rather discover them, and that the best mathematical ideas are those that have been discovered for their own sake, without any practical application in mind.
The second part of the book focuses on the role of a mathematician in society. Hardy argues that mathematics is a pure and idealistic pursuit that has little direct practical application. He suggests that this is a good thing, as it allows mathematicians to work on problems purely for the sake of their beauty and intellectual challenge. Hardy also discusses the idea that mathematics is a young person's game, and that mathematicians tend to do their best work when they are young and have not yet been corrupted by the practical concerns of the world.
Overall, "A Mathematician's Apology" is a thought-provoking and insightful reflection on the nature of mathematics and the role of a mathematician in society. The book is written in a clear and accessible style, and it has inspired generations of mathematicians and non-mathematicians alike to think deeply about the beauty and importance of mathematics.
