One of the pre-eminent physicists of our time selects and comments on the greatest mathematical results ever. The selection of results is perfect, but the commentary is flawed, fatally in places. The worst example I found is in the commentary on Galois. There, Hawking writes, 'To be brief, Galois demonstrated that the general polynomial of degree n could be solved by radicals if and only if every subgroup N of the group of permutations Sn is a normal subgroup. Then he demonstrated that every subgroup of Sn is normal for all n≤ 4 but not for any n 5.' Never mind the typo that would leave the reader wondering about the case n=5. Not every subgroup of S3 or S4 is normal, so this explanation is factually inaccurate. Personally, I wouldn't buy this book until a new edition is released that corrects errors such as these.
