Title: focuses on the contributions of Abel to the unsolvability of the quintic
Review: Abel's Proof takes an interesting approach to mathematical writing. The author places all mathematical formulas and derivations in boxes that are separate from the flow of the text so you don't have to do the math if all you want is a knowledge of the history of this era in mathematics. The author does a great job of explaining this history, covering the story of the factoring of polynomials in general but focusing on the unsolvability of the quintic. Abel's life of poverty is covered in detail. There is a lot of mathematics, if you are interested, including how to factor a cubic polynomial and Abel's proof of the unsolvability of the quintic. I found the math somewhat hard to follow but worth the effort of doing so. I found Abel's story to be very sad. The book is worth reading just for his life story alone.
