Very nice book on the subject. Not sure if experts will like it, but as an outsider who only learned group theory for physics purposes and has been asking for long how the stuff from that course can be related to Galois theory about polynomial roots, I find this connection very well elucidated in this book. Reading this book is just like reading a novel, greatly owing to the fact that the style is very much not like the standard "theorem-proof-theorem-proof". Instead, motivations and examples always precede the introduction of an important theorem and its proof.<br><br>In particular, I really find enlightening the author's discussion on the use of axiomatic approach in abstract algebra and the insightful explanation of homomorphism.
