<p/><br></br><p><b> About the Book </b></p></br></br>"The exposition is quite efficient, packing much material in a limited number of pages. . . . The greatest asset of this book is its nice selection of topics, focusing on the fundamental theorem of Galois theory and its application to solvability of equations by radicals. . . The style is no-nonsense, crisp . . ".--"The American Mathematical Monthly" (on first edition).<p/><br></br><p><b> Book Synopsis </b></p></br></br>There are too many errors in the first edition, and so a "corrected nth print- ing" would have been appropriate. However, given the opportunity to make changes, I felt that a second edition would give me the flexibility to change any portion of the text that I felt I could improve. The first edition aimed to give a geodesic path to the Fundamental Theorem of Galois Theory, and I still think its brevity is valuable. Alas, the book is now a bit longer, but I feel that the changes are worthwhile. I began by rewriting almost all the text, trying to make proofs clearer, and often giving more details than before. Since many students find the road to the Fundamental Theorem an intricate one, the book now begins with a short section on symmetry groups of polygons in the plane; an analogy of polygons and their symme- try groups with polynomials and their Galois groups can serve as a guide by helping readers organize the various definitions and constructions. The exposition has been reorganized so that the discussion of solvability by radicals now appears later; this makes the proof of the Abel-Ruffini theo- rem easier to digest. I have also included several theorems not in the first edition. For example, the Casus Irreducibilis is now proved, in keeping with a historical interest lurking in these pages.
