If this book is intended primarily for future and current PhD students and doctors (who relive well-known situations ... which advantageously benefit from a selection of blogs and sites that may interest them), it will help the environment, who do not always understand what this work enter, a little better, what life of a PhD student. The set is an ideal length (not too short nor too long, even if the end comes very quickly), the designs are simple but pleasant ... a little guilty pleasure. To discover!
