His review of Black's 'Neural Networks for Pattern Recognition' made me chuckle, and accorded with my own experience of the book.
To the reviewer who said "I was looking forward to a detailed insight into
neural networks in this book. Instead, almost every page is plastered up
with sigma notation", that's like saying about a book on music theory
"Instead, almost every page is plastered with black-and-white ovals (some
with sticks on the edge)." Or to the reviewer who complains this book is
limited to the mathematical side of neural nets, that's like complaining
about a cookbook on beef being limited to the carnivore side.
