I am looking for assistance from someone who read Carl Jensen's book and comprehends it well.

1) What is the background of the author and describe how is it relevant to the understanding the main purpose of the book?

2) prepare down the thesis of the book? How successful is the author of getting his point across to the reader and does he really prove what the thesis claims to show? describe how do we know this (what are some specific illustrations as to how he does or doesn't prove his thesis and how he could have enhanced)?
